German component icon Tune certainly had one of the most creative booths at this year's Eurobike show - James Huang / Immediate Media
Tune focused its attention this year on the fat bike market, launching new hubs as well as associated quick-release skewers and thru-axles. Note the claimed weights, too - yowza! - James Huang / Immediate Media
Tune built up this 9:Zero:7 Carbon Whiteout frame with a smattering of its own parts, and as expected, the result was exceptionally light - James Huang / Immediate Media
How light, you ask? Well, 9.1kg (20.06lb) is mighty impressive for a fat bike - James Huang / Immediate Media
Although most of the parts come from Tune, certainly elements are borrowed from other companies, such as the Kuroshiro carbon rims and Brake Force One disc brakes - James Huang / Immediate Media
The Tune carbon crank is fitted with an integrated chainring from UK company Absolute Black - James Huang / Immediate Media
If scenes like this look familiar, that's because they're often used in Tune's print catalogues - James Huang / Immediate Media
Tune says it received unexpectedly positive response to its Spurtreau - a laser-based alignment tool to help mechanics get stems perfectly lined up with the front wheel - James Huang / Immediate Media
Does a display like this really showcase Tune's products? Not really, but we sure remembered it - and that was exactly what company founder Uli Fahl intended - James Huang / Immediate Media
Acros's A-GE hydraulic derailleur system has been updated to handle 1x11 cassettes - James Huang / Immediate Media
New from Acros is a range of 35mm-diameter bars, which are available in three different finishes - James Huang / Immediate Media
Of course, Acros also announced a collection of matching 35mm-diameter stems - James Huang / Immediate Media
Acros offers its A-Flat pedals in three platform sizes to suit rider preferences. The A-Flat SL is the smallest and lightest option and only comes with a titanium spindle - James Huang / Immediate Media
Riders that prefer a very large platform - such as many DH racers - would likely turn to the Acros A-Flat XL, which is about 30mm longer and 12mm wider than the smallest version - James Huang / Immediate Media
Acros has developed a new line of hubs for 2015 called Nineteen - a reference to the 19mm-diameter carbon fibre axle hidden away inside - James Huang / Immediate Media
The Acros A-GE hydraulic shifter hasn't changed and is still quite a marvel of CNC machining - James Huang / Immediate Media
Acros makes a variety of componentry but the company's tools are also quite impressive. This bottom bracket tool, for example, features a full-length 24mm shaft to ensure that the cups thread in straight - James Huang / Immediate Media
Looking for a super burly headset press? Acros is happy to help - James Huang / Immediate Media
Acros showed off a new prototype, ultralight mountain bike hardtail built with sustainably produced cellulose fibre tubes held together with pressure-sensitive adhesives - James Huang / Immediate Media
Custom angles would be no problem with this kind of construction - but it's strictly a dry-conditions item - James Huang / Immediate Media
The 19mm-diameter carbon fibre axle on the new Acros cross-country and road hubs features an adjustable bearing preload collar similar to what's used on its i-Lock headsets - James Huang / Immediate Media
Virtually the entire Acros booth was made of corrugated cardboard - James Huang / Immediate Media
Acros says its entire Eurobike booth - which was quite sizeable - easily fit inside a standard van - James Huang / Immediate Media
New from Acros is a conversion kit to adapt its bottom brackets to SRAM GXP cranksets - James Huang / Immediate Media
New from Trickstuff is this ultralight 11-41T mountain bike cassette, which uses a mix of aluminium and steel cogs - James Huang / Immediate Media
Care more about weight than durability? Take a look at Trickstuff's range of carbon fibre chain guides with weights that range from 28 to 110g - James Huang / Immediate Media
Trickstuff also offers a 41-tooth cog that retrofits on to standard 10-speed Shimano and SRAM cassettes - as long as you're willing to deal with ditching the 17-tooth cog in the process - James Huang / Immediate Media
Trickstuff offers its own range of disc brake pads that use a thin, stainless steel backing plate that then allows for more pad material than usual - James Huang / Immediate Media
Carbonice is yet another German company offering a wide range of ultralight carbon fibre bits - James Huang / Immediate Media
Looking to burn a pile of money to save a few grams? Carbonice is ready to help you - James Huang / Immediate Media
This carbon fibre seatpost collar from Carbonice supposedly weighs just 6.6g - and costs €35 - James Huang / Immediate Media
THM-Carbones' ultra-exclusive Clavicula SE carbon fibre crankset supposedly weighs just 287g for the arms and spindle. Total weight including chainrings and a threaded bottom bracket is a staggering 509g - but retail cost is a similarly incredible €1,270 - James Huang / Immediate Media
The original THM-Carbones Clavicula crankset now becomes the Clavicula Classic - James Huang / Immediate Media
The THM-Carbones Fibula carbon brakes aren't new but they're still amazing to behold - James Huang / Immediate Media
German companies certainly lean on their collective carbon fibre reputation pretty hard - James Huang / Immediate Media
Carbonice offers machined carbon fibre pulleys - James Huang / Immediate Media
Carbonice was first founded with these 4.5g carbon fibre front derailleur braze-on clamps. Other items quickly followed - James Huang / Immediate Media
In case the stock SRAM and Avid clamps are too heavy for you - James Huang / Immediate Media
Carbonice's ultralight headset spacers feature a carbon fibre outer skin but two thin rings of aluminium inside - James Huang / Immediate Media
Clamps like these are common in ultralight seatposts - James Huang / Immediate Media
Suspension company German A can easily build forks in any number of configurations given their modular design - James Huang / Immediate Media
Rather than use a tapered steerer tube, German A uses a straight 1 1/8in carbon fibre tube and builds the lower bearing race seat into the crown - James Huang / Immediate Media
The exposed rebound adjuster mechanism doesn't look to be terribly mud-friendly on this German A fork but it sure looks cool - James Huang / Immediate Media
German A's Revo inverted downhill fork uses teardrop-shaped upper tubes for extra stiffness - James Huang / Immediate Media
Linkage forks may have disappeared from the American landscape ages ago but they're alive and well in Germany - James Huang / Immediate Media
Longstanding champion of ultra-feathery wheels Lightweight shifted gears for Eurobike, instead showcasing this intriguing e-bike project - James Huang / Immediate Media
The blank carbon fibre panels would ultimately be replaced by various instrument panels - James Huang / Immediate Media
Lightweight's e-bike concept skips over traditional motors in favour of a novel drive system. Magnets line the entire rim of the rear wheel, which are accelerated as they pass through the frame - James Huang / Immediate Media
Access to the motor guts is provided via this removable panel down below - James Huang / Immediate Media
Haero Carbon's new H.135 mountain bike bar is aimed at endurance racers that might appreciate the slightly aero position - James Huang / Immediate Media
The Haero Carbon H.380 modular bar system is designed for triathletes that use the same bike for general road riding and racing. The short extension shown here is aimed at short-course races and can be replaced with longer extension for longer events. The tops are shaped so that they serve double duty as armrests. Retail price is €450 - James Huang / Immediate Media
The Haero Carbon H.253 carbon fibre integrated aero bar supposedly weighs just 350g. Prices start at €699 - James Huang / Immediate Media
Riders that tackle predominantly uphill time trials might be interested in the Haero Carbon H.155, which starts life as a 178g drop bar but can be easily fitted with full-length or short, looped extensions for faster sections. Prices start at €415 - James Huang / Immediate Media
Haero Carbon also had some of the most impressive branding at Eurobike. Anyone fancy an apple? If nothing else, these were a heck of a lot cheaper than anything else in the booth - James Huang / Immediate Media
Germany's BrakeForceOne has ditched its old carbon reinforced plastic master cylinders for all-aluminium construction that not only looks far better but feels better in your fingers, too - James Huang / Immediate Media
BrakeForceOne still contends that its disc brakes are so powerful that you'll never require more than one finger. That said, the company also offers a two-finger blade - James Huang / Immediate Media
BrakeForceOne's massive aluminium caliper has no cutouts for cooling airflow. Instead, the company says the caliper's large surface area is enough to dissipate excess heat - James Huang / Immediate Media
BrakeForceOne also has its own collection of stainless steel brake rotors, all of which are quite light. Claimed weight for a single 160mm-diameter rotor is just 97g - James Huang / Immediate Media
New from BrakeForceOne is the BFO M caliper. Instead of using a conventional coil-spring for the secondary hydraulic booster valve - which is the key to BrakeForceOne's impressive power - the BFO M uses a magnetic valve that requires less force to open. There's no change in braking power but less effort required at the lever - James Huang / Immediate Media
Reset Racing has a wide range of no-bleed shock pump adapters - James Huang / Immediate Media
Got a Truvativ Hammerschmidt? This widget from Reset Racing reduces the chances of damaging your housing if you frequently ride in rocky or excessively technical terrain - James Huang / Immediate Media
These flat pedals from Reset Racing look absolutely vicious - James Huang / Immediate Media
Rohloff's iconic Speedhub 14-speed internally geared rear hub is now available in a fat bike version called Speedhub XL. As of right now, though, there is no thru-axle version - James Huang / Immediate Media
Think road bike disc wheels have to be heavy? The AX-Lightness U 28C D carbon clinchers supposedly come in at just 1,110g for the pair - James Huang / Immediate Media
Helping AX-Lightness hit that incredible weight figure is Extralite's CyberFront and CyberRear hubs - James Huang / Immediate Media
AX-Lightness equips its U 28C D carbon clinchers with a tubeless-ready profile - James Huang / Immediate Media
AX-Lightness's carbon tubular disc road wheelsets are even more shockingly light. Claimed weight for the 24mm-deep P 24T ED is a staggering 880g per pair (!) while the 38mm-deep P 38T TD is still just 1,030g per set - James Huang / Immediate Media
The AX-Lightness Vial Evo carbon fibre road frame has a claimed weight of just 660 to 720g but this one is only 650g - and that's with a seatpost collar and rear derailleur hanger - James Huang / Immediate Media
AX-Lightness builds the Vial Evo in its factory in Creussen, Germany - James Huang / Immediate Media
The raw look may not appeal to everyone but the fact of the matter is that paint is heavy - and there's no way the AX-Lightness Vial Evo could hit its incredibly low weight with any sort of conventional finish - James Huang / Immediate Media
The raw finish leaves all of AX-Lightness's handiwork plain to see - James Huang / Immediate Media
The internal cable routing system on the AX-Lightness Vial Evo definitely isn't the most convenient to set up - although running a full-length liner would certainly help - James Huang / Immediate Media
AX-Lightness has developed solutions for riders that need to lower their bar height (although it's not the most aesthetically pleasing item we've seen). That said, claimed weight is incredibly low at just 68 to 80g, depending on size - James Huang / Immediate Media
The carbon fibre stem extension on the AX-Lightness Rigid stem is sandwiched between an aluminium faceplate and two small aluminium backing plates - plus titanium bolts, of course - James Huang / Immediate Media
AX-Lightness also showed off these machined aluminium cranks - James Huang / Immediate Media
Quite the neat display from AX-Lightness - James Huang / Immediate Media
Gearbox transmissions are far from dead - although their supporters are still frustrated by the slow development of compatible frames. German company Pinion offers one of the most compact and elegant options we've seen with a total gearing range as high as 568 percent, which is nearly as generous as conventional triple drivetrains - James Huang / Immediate Media
Since all of the gears are completely encased with the aluminium housing, Pinion's gearbox drivetrains are essentially modular units. The transmission is thus also protected from the elements, Pinion claims a 10,000km service interval, and there are minimal external drivetrain components exposed to impact damage - James Huang / Immediate Media
Pinion's P1.9XR model clearly trumps conventional 1x drivetrains in terms of overall range - James Huang / Immediate Media
As enticing as the Pinion gearbox system might be, not everyone will get on with the twist-style shifter. And although the 2,200g (4.85lb) claimed weight of the lightest P1.9CR model is impressive given that it replaces an entire drivetrain, it's still heavier than other high-end options - James Huang / Immediate Media
Full-suspension bikes equipped with Pinion gearbox transmissions will often require this tensioner to account for chain stay growth as the rear end moves through its travel - James Huang / Immediate Media
The German bike industry has always been a star of the Eurobike show and this year's event only further reinforced that trend. Carbon fibre once again is the primary material of choice for ultralight principals such as AX-Lightness, THM-Carbones and Carbonice, but companies such as Tune, German A, Trickstuff and Acros continue to demonstrate that aluminium still has its place.
Here's some more details on a few highlights but be sure to browse through the image gallery for even more lustworthy bits and pieces such to whet your tech weenie appetite – and your wallet.
Staggeringly light road disc wheels from AX-Lightness
AX-Lightness showed off a range of astoundingly light road disc wheels, all built with carbon fibre clincher or tubular rims built in the company's German headquarters.
Think road bike disc wheels have to be heavy? the ax-lightness u 28c d carbon clinchers supposedly come in at just 1,110g for the pair:
Road disc brake clinchers weighing just 1,110g per pair? Yes, please
Headlining the range are the P 24T ED tubulars, built around Extralite CyberFront and CyberRear six-bolt disc hubs and straight-pull, ultra-thin stainless steel spokes for a claimed weight of just 880g. Clinchers weigh as little as 1,110g per set.
AX-Lightness doesn't seem to have skimped on the rim features, either. Both the tubulars and clinchers are available in 24mm and 38mm depths, while the clinchers are built with a tubeless-ready profile and have a generously sized 18mm internal width.
AX-Lightness equips its u 28c d carbon clinchers with a tubeless-ready profile:
AX-Lightness's carbon clincher road rims are generously sized with an 18mm internal width. They're also tubeless-compatible
AX-Lightness also continues its incredible Vial Evo carbon fibre road frame with claimed weights between 660g and 720g depending on size (although the one on display was only 650g). Efficiency of material is the name of the game here, with mostly round or modified oval cross-sections, relatively large tube diameters, and smooth transitions throughout.
Like the rims, AX-Lightness builds the Vial Evo in its German factory and the raw finish leaves nothing to hide. That said, the frame design may be form-follows-function but it's awfully nice to look at nonetheless.
The ax-lightness vial evo carbon fiber road frame has a claimed weight of just 660-720g but this one is only 650g - and that's with a seatpost collar and rear derailleur hanger:
650g of carbon fibre goodness
THM-Carbones' new Clavicula SE cranks break the 300g barrier
How light can carbon cranks get, we wonder? THM-Carbones has updated its long-running Clavicula and created the Clavicula SE, built with moulded carbon fibre arms and a carbon fibre spindle that supposedly weigh just 287g.
The claimed weight for a complete setup with bottom bracket and 53/39-tooth Praxis Works chainrings is an unbelievable 509g. That's roughly 200g lighter than comparably configured top-end offerings from the big three and an even more incredible figure when you look at it in terms of percentage.
THM-Carbones' ultra-exclusive clavicula se carbon fiber crankset supposedly weighs just 287g for the arms and spindle. total weight including chainrings and a threaded bottom bracket is a staggering 509g - but retail cost is a similarly incredible ó1,270:
THM-Carbones' new Clavicula SE cranks are unbelievably lightweight – and pretty
As compared to the original Clavicula – which will continue to be sold as the Clavicula Classic – the new SE boasts a more skeletal five-arm spider and a driveside arm that's now hollow where it's joined with the axle.
THM-Carbones has also built in a wide range of compatibility, too, with options to fit threaded, PF86, PF30, BB30, BBright, and BB386EVO bottom bracket shells.
Carbonice shaves off the grams
Looking to cut a few grams and got some money burning a hole in your wallet? Carbonice first established itself in 2008 with a carbon fibre braze-on front derailleur adapter that weighed a claimed 4.5g, but the company now has a fairly wide range of bits catering to hardcore weight weenies.
Carbonice was first founded with these 4.5g carbon fiber front derailleur braze-on clamps. other items quickly followed:
Try not to think too much about what these things cost
Examples include a 750mm-wide riser bar at just 124g, 10g Matchmaker X clamp setups for SRAM/Avid brakes and trigger shifters, a 5g seatpost collar and a 3g chain catcher.
As you'd guess, the prices aren't exactly cheap. The handlebar will set you back €200, the clamps are €60, the seatpost collar is €73, and the chain catcher is €20. And that braze-on derailleur adapter? That'll set you back a cool €50.
This carbon fiber seatpost collar from carbonice supposedly weighs just 6.6g - and costs ó35:
Naturally, you have to pay more to get less
Tune gets fat
Tune is perhaps best known for its hubs and this year the company has decided to concentrate on fat bikes – already a well established market in the US but a segment that's apparently seeing steady growth in Europe.
The Fat Kong rear hub comes in as low as 240g – the same as many high-end conventional mountain bike hubs. Tune will offer it in both 170mm and 190mm widths for quick-release dropouts along with the corresponding 177mm and 197mm thru-axle variants.
Tune focused its attention this year on the fat bike market, launching new hubs as well as associated quick-release skewers and thru-axles. note the claimed weights, too - yowza:
Tune is banking on the continued growth of the fat bike market
The matching Fat King front hub weighs as little as 139g and will be available in 135, 142, and 150mm spacing.
Naturally, Tune saw fit to do a complete fat bike build to showcase the other items in its stable. Centered around a 9:Zero:7 Carbon Whiteout, the showpiece came in at just 9.1kg (20.06lb) without pedals.
Tune built up this 9:zero:7 carbon whiteout frame with a smattering of its own parts, and as expected, the result was exceptionally light:
9.1kg, all in
Lightweight's surprise e-bike concept
Lightweight had its usual collection of silly-light carbon fibre road wheels (in both disc and rim brake varieties) at Eurobike along with its recently introduced Urgestalt road frame.
What came as a complete surprise to us, however, was the e-bike concept on display in its booth – a project commissioned by the German Federal Ministry of Education and Research.
Longstanding champion of ultra-feathery wheels lightweight shifted gears for eurobike, instead showcasing this intriguing e-bike project:
Not many expected to see a concept e-bike in the Lightweight booth at Eurobike
Built around a carbon fibre frame and fork (naturally), the bike features a highly integrated design with the drive system, battery, lights and controls all forming a rather cohesive-looking shape. Hidden inside the chassis is a new type of drive system that uses a string of magnets situated around the rim, which are then accelerated as they pass through the frame.
Keep in mind that the bike is still in concept form but the designers claim a healthy 500-watt boost on top of the rider's pedaling efforts plus a sub-15kg (33lb) target weight.
Lightweight's e-bike concept skips over traditional motors in favor of a novel drive system. magnets line the entire rim of the rear wheel, which are accelerated as they pass through the frame:
The rear wheel is driven via the magnets that are situated around the perimeter of the rim
Who knows if it'll ever see the light of day but we'll certainly never discourage anyone from aiming just a little bit higher.
