Hill climb racing is all about your power-to-weight ratio and while aero considerations come in to play on longer or faster courses, there are still potentially significant gains to be made by dropping weight from your bike.
Similarly, as hill climbs in the UK are governed by the CTT and not the UCI, the 6.8kg minimum weight doesn't apply here. You can run pretty much any bike you like, so long as it's not a recumbent and it has two brakes (or one brake if it's a fixed gear).
Removing brake pad retaining bolts? It must be a hill climb. - @mattgrayson_photo - http://instagram.com/mattgrayson_photo
Potential performance gains aside, dropping grams from your bike is also a lot of fun, and ogling the resulting builds is even more fun (and less harmful to your bank account than doing it yourself).
We were at the National Hill Climb Championships at the weekend to scope out the sauciest lightweight tech on show, and the nine bikes we picked certainly don't disappoint.
Held in Streatley near Reading, this year's nationals course ran over 0.8 kilometres with an average gradient of 13 per cent, peppered with a maximum, gut-wrenching section of 25.9 per cent.
The event's enormous 479-strong start list was also notable for the size of the women's field. A record 140 female riders lined up for this year's nationals, thanks in large to efforts of riders such as Laurie Pestana, whose campaigning saw sponsors fund the places of around 90 female riders.

The 2020 men's hill climb national champion – and friend of BikeRadar – Andrew Feather rode his 5.4kg 2019 Cannondale SuperSix Evo to victory. - @mattgrayson_photo - http://instagram.com/mattgrayson_photo
Andrew Feather – a man lightweight by name and nature. - @mattgrayson_photo - http://instagram.com/mattgrayson_photo
Andrew rides with a 61kg Schmolke carbon saddle, which is paired with an Mcfk seat post. - @mattgrayson_photo - http://instagram.com/mattgrayson_photo
Andrew uses CaneCreek EE brakes with a custom red accent. - @mattgrayson_photo - http://instagram.com/mattgrayson_photo
A C-Bear ceramic bottom bracket should reduce friction, saving precious watts. - @mattgrayson_photo - http://instagram.com/mattgrayson_photo
Andrew uses a Rotor Aldhu Crank that is paired with the brand's InSpider spider-based power meter. - @mattgrayson_photo - http://instagram.com/mattgrayson_photo
A previous-generation Red eTap rear derailleur takes charge of shifting. - @mattgrayson_photo - http://instagram.com/mattgrayson_photo
Hunt's Hill Climb SL wheels were a popular choice on the day. They weigh just 900g for the pair. - @mattgrayson_photo - http://instagram.com/mattgrayson_photo
Andrew has switched to 42cm bars this year, preferring their feel when climbing out of the saddle. Last year he rode 38cm bars. Andrew is also using an Alpitude Stelvio carbon out-front Garmin mount, which weighs just 15g. - @mattgrayson_photo - http://instagram.com/mattgrayson_photo
The rear derailleur is upgraded with a set of C-Bear jockey wheels. - @mattgrayson_photo - http://instagram.com/mattgrayson_photo
Be sure to use a torque wrench whenever there is carbon involved. - @mattgrayson_photo - http://instagram.com/mattgrayson_photo
Andrew Feather (HuntBikeWheels.com) has had a perfect hill climb season, winning every single race he entered.
He also took his second win at the nationals following his 2018 victory, with a time of 2:04.86. For this year's event, he rode the same 2019 Cannondale SuperSix EVO he has raced on for the past two seasons.
Bithja Jones' 5.6kg Tifosi Mons
Bithja Jones, who won the women's event, rode this Tifosi Mons, which weighs in at just 5.6kg. - @mattgrayson_photo - http://instagram.com/mattgrayson_photo
This Time Carbon Pro saddle isn't one for long days out but, for a short hill climb, comfort isn't a priority. - @mattgrayson_photo - http://instagram.com/mattgrayson_photo
Bithja uses a deeper-than-average Fulcrum Racing Speed wheelset, believing there are significant benefits to the extra stiffness that comes with them for riders that pedal predominantly out of the saddle. The rear wheel is 55mm deep and the front are 40mm. The front doesn't need to be as stiff, hence a shallower depth. On longer or faster climbs there will, of course, also be an aerodynamic benefit compared to a shallower wheelset. - @mattgrayson_photo - http://instagram.com/mattgrayson_photo
The shifting components have been totally gutted from the left lever, leaving just the brake lever. - @mattgrayson_photo - http://instagram.com/mattgrayson_photo
Bithja runs a Hope narrow-wide chainring to improve chain security with the non-clutched rear derailleur. - @mattgrayson_photo - http://instagram.com/mattgrayson_photo
Absolutely all non-essential parts – including even the screws in the brake blocks – are removed to reduce weight. - @mattgrayson_photo - http://instagram.com/mattgrayson_photo
Bithja uses wider-than-average Trigon Dual Groove bars to improve feel and increase leverage when climbing out of the saddle. - @mattgrayson_photo - http://instagram.com/mattgrayson_photo
The wheels are secured with a pair of lightweight Token skewers. - @mattgrayson_photo - http://instagram.com/mattgrayson_photo
Bithja rode the even in honour of David Little, who passed away due to lung disease. His wife, Isha Little, has sponsored the frame. - @mattgrayson_photo - http://instagram.com/mattgrayson_photo
Bithja Jones (Pankhurst Cycles) took the win in the women's event with a time of 2:47.94 on her Tifosi Mons.
Bithja has had an equally impressive season, taking wins at Berkhamsted CC, Newbury Velo and Blazing Saddles' promotions this season.
Her 5.6kg bike is notable for its use of (in the context of hill climbing) deep Fulcrum Racing Speed wheels
Tom Bell's 5.5kg Rose X-Lite Team
Tom Bell (another friend of BikeRadar and semi-regular contributor to the site) took second in the men's event on this Rose X-Lite Team, which weighs just 5.5kg. - @mattgrayson_photo - http://instagram.com/mattgrayson_photo
Tom runs the bike in a 1x configutation with a 40t Wolf Tooth narrow-wide chainring. - @mattgrayson_photo - http://instagram.com/mattgrayson_photo
An Mcfk saddle sits atop a Mt Zoom seatpost. - @mattgrayson_photo - http://instagram.com/mattgrayson_photo
The Rotor Uno 11-28t cassette is among the very lightest cassettes out there. - @mattgrayson_photo - http://instagram.com/mattgrayson_photo
Super lightweight Mt Zoom skewers hold the wheelset in place. - @mattgrayson_photo - http://instagram.com/mattgrayson_photo
With a background in world cup-level XC racing, Tom prefers Shimano XTR SPD pedals. He has also found it easier to clip-in to the pedals at the start of a climb since – owing to Coranavirus restrictions – there is no longer a marshall to hold you at the start of the race. - @mattgrayson_photo - http://instagram.com/mattgrayson_photo
Tom Bell (High North Performance) – also a friend of BikeRadar and semi-regular contributor – took second in the men's event with a time of 2:05.93.
He rode a Rose X-Lite Team that, notably, was fitted with a pair of Shimano XTR SPD mountain bike pedals. Click through the gallery above to find out why!
Hamish McDougall's 5.3kg Dolan Seta
Hamish McDougall – who placed a more-than-respectable 54th on the day – rides a Dolan Seta Track bike that he has whittled down to a mere 5.3kg. - @mattgrayson_photo - http://instagram.com/mattgrayson_photo
Hamish ran a 19t Talon alloy sprocket paired with a 39t chainring for the big day. - @mattgrayson_photo - http://instagram.com/mattgrayson_photo
This brake lever weighs in at a mere 40g. CTT regulations dictate that fixed gear bikes only require one brake, reducing weight further. - @mattgrayson_photo - http://instagram.com/mattgrayson_photo
Hamish has swapped the stock fork for an Easton EC90 carbon fork that weighs considerablyy less than the track forks that came with the bike. The Planet X CNC brake calliper is similarly feathery, weighing just 105g each. - @mattgrayson_photo - http://instagram.com/mattgrayson_photo
As mentioned, Hamish ran a 39 x 19t gear ratio on the day. Running the chainring on the inside of the spider gives an acceptable chain line for the fixed gear drivetrain. - @mattgrayson_photo - http://instagram.com/mattgrayson_photo
The Vittoria Cronos tyres in an alarmingly-narrow 22mm width weigh in at 165g each. - @mattgrayson_photo - http://instagram.com/mattgrayson_photo
Hamish rides a 56cm frame with a 140mm stem. He undersizes his usual frame size and compensates with a longer stem to reduce overall weight of the bike. - @mattgrayson_photo - http://instagram.com/mattgrayson_photo
The low profile carbon rims are laced to super light Novatec Hubs. - @mattgrayson_photo - http://instagram.com/mattgrayson_photo
Hamish McDougall (Team Lifting Gear Products/Cycles In Motion) possesses two notable things – one of the best/angriest pain faces of any hill climber we have come across and this wonderfully uncompromising fixed gear hill climb bike.
Built around a Dolan Seta track frame, Hamish ran a 39×19t gear on the day for the 13 per cent average gradient climb, which included pitches up to 25 per cent. Perhaps that explains the pain face.
Mary Wilkinson's 7kg Vertex SLR
Mary Wilkinson, who came second in the women's event, rode this Vertex SLR, which weighs just under 7kg. - @mattgrayson_photo - http://instagram.com/mattgrayson_photo
Mary uses these (comparatively) deep-rimmed Corima wheels for hill climbs. - @mattgrayson_photo - http://instagram.com/mattgrayson_photo
Mary ran a Vittoria Triathlon Evo on the front wheel. These are lighter than the Vittoria Corsa Evo on the rear, but she finds the Corsa gives a bit more grip on slippery surfaces. - @mattgrayson_photo - http://instagram.com/mattgrayson_photo
A 38t Dura-Ace chainring was chosen over a 36t for the event. - @mattgrayson_photo - http://instagram.com/mattgrayson_photo
This is paired with an 11-27t cassette. - @mattgrayson_photo - http://instagram.com/mattgrayson_photo
Stopping on the way back down the hill is taken care of by a pair of FSA Energy brakes. - @mattgrayson_photo - http://instagram.com/mattgrayson_photo
Mary Wilkinson (Yorkshire Road Club) came second in the women's event aboard this ~7kg Vertex SLR.
As well as running an interesting mix of 10-speed era Shimano Dura-Ace and Ultegra components, Mary also opted for a grippier rear tyre, which was a wise choice because riders in the latter half of the event suffered from heavy rain showers.
Josh Coyne's 5.5kg Cube Litening
Josh Coyne, who placed 45th in the men's event, rides this Cube Litening, which weighs in at an impressively light 5.5kg. - @mattgrayson_photo - http://instagram.com/mattgrayson_photo
Josh Run's a Dura-Ace crankset paired with an Ultegra Di2 rear mech. A 1x oval chainring sits on the outboard face of the spider. - @mattgrayson_photo - http://instagram.com/mattgrayson_photo
Josh also uses Hunt's Hill Climb SL wheels. These are fitted with Vittoria Corsa Speed tyres. - @mattgrayson_photo - http://instagram.com/mattgrayson_photo
Josh uses a Dura-Ace TT shifter with a modified cable that operates just the rear derailleur. - @mattgrayson_photo - http://instagram.com/mattgrayson_photo
CaneCreek EE brakes are among the very lightest rim brakes you can get. - @mattgrayson_photo - http://instagram.com/mattgrayson_photo
Every gram is a prisoner on a hill climb bike and even the expander bung and top cap has been removed on Josh's bike. - @mattgrayson_photo - http://instagram.com/mattgrayson_photo
A slither of grip tape adds some security without a meaningful weight penalty. - @mattgrayson_photo - http://instagram.com/mattgrayson_photo
Profile's Svet TT base bars are among the lightest base bars on the market. Bull horn style bars are popular in hill climbs as the drops are never used on the typically short and steep climbs. - @mattgrayson_photo - http://instagram.com/mattgrayson_photo
Josh Coyne's (Bpm Coaching) 5.5kg Cube Litening is one of our favourite bikes from the day.
The super-clean build features all sorts of interesting tech, with the Profile Svet TT bull horn bars being a particular highlight.
Marcus Cram's sub-5kg Sarto Asola
Marcus Cram, who placed 30th on the day, rode this custom Sarto Asola, which has a frame weight of just 700g. The frame has no paint – just raw carbon layup with a protective top layer. It was custom built in Italy and assembled by Backyard Bikeshop in Newcastle. The complete bike weighs under 5kg. - @mattgrayson_photo - http://instagram.com/mattgrayson_photo
Running no bar tape or bar hoods help get the bike under 5kg. The drops are retained as that is Marcus' preferred riding position. - @mattgrayson_photo - http://instagram.com/mattgrayson_photo
The bike is built around an 11-speed generation SRAM Red eTap groupset. - @mattgrayson_photo - http://instagram.com/mattgrayson_photo
The wheels are custom-made by Rick Bailey and weigh in at just 990g for the pair. - @mattgrayson_photo - http://instagram.com/mattgrayson_photo
Edco's cassettes are a true weight weenie special and are rarely seen outside of the discipline. - @mattgrayson_photo - http://instagram.com/mattgrayson_photo
This Ultimate USE Evo seat post weighs a feathery 121g. - @mattgrayson_photo - http://instagram.com/mattgrayson_photo
Once again, CaneCreeks EE brakes are a common sight at hill climbs thanks to their low weight. - @mattgrayson_photo - http://instagram.com/mattgrayson_photo
Marcus Cram's (Blaydon CC) sub-5kg custom Sarto Asola is one of the lightest bikes we saw on the day. Based around a 700g frame that was custom built in Italy and assembled by Backyard Bikeshop in Newcastle, the complete bike weighs under 5kg.
The ludicrously lovely boutique build and unpainted finish also goes some way to bringing the weight down.
Bexy Dew's Colnago V2R
Bexy Dew, who came fifth in the women's category, rode this lovely Colnago V2-R. - @mattgrayson_photo - http://instagram.com/mattgrayson_photo
Bexy run's Prime Primavera X-lite carbon handlebars without bar tape to save on weight. - @mattgrayson_photo - http://instagram.com/mattgrayson_photo
Continuing with the Italian theme, the bike is built around a Campagnolo Super Record EPS groupset. - @mattgrayson_photo - http://instagram.com/mattgrayson_photo
Bexy uses Hunt's Hill Climb SL Tubular wheels, which are fitted with Vittoria Corsa Graphene 2.0 tyres. - @mattgrayson_photo - http://instagram.com/mattgrayson_photo
Bexy is running the 11-speed era version of the groupset. - @mattgrayson_photo - http://instagram.com/mattgrayson_photo
An Astute Skylite SR is Bexy's saddle of choice. - @mattgrayson_photo - http://instagram.com/mattgrayson_photo
Bexy Dew (Army Cycling) placed fifth in the women's event aboard this beautiful Colnago V2R.
Though we didn't catch a weight for the bike, it really doesn't matter – we're happy just ogling that classic Campagnolo SuperRecord EPS groupset and those tan wall tyres.
The bike is fitted with a pair of Edco Vue des Alpes wheels. - @mattgrayson_photo - http://instagram.com/mattgrayson_photo
These are fitted with a pair of Continental Podium light tyres, which give a good balance of weight and resistance to punctures. - @mattgrayson_photo - http://instagram.com/mattgrayson_photo
Nicola runs a Dura-Ace crankset with the outer chainring removed. - @mattgrayson_photo - http://instagram.com/mattgrayson_photo
The Dura-Ace drivetrain is finished with a fetching red trim an extra touch of style. - @mattgrayson_photo - http://instagram.com/mattgrayson_photo
Nicola uses Garmin Vector power meter pedals. - @mattgrayson_photo - http://instagram.com/mattgrayson_photo
To save weight, the hoods have been removed, the drops sawn off and the left gear lever and cabling have been removed. Going one step further than most, a section of the brake lever has also been chopped off. Madness! - @mattgrayson_photo - http://instagram.com/mattgrayson_photo
Nicola Soden's (Datalynx-Parenesis Cycling) Parlee features some of the wildest modifications we spotted on the day.
Going as far as chopping the rear brake lever in half and removing the brake pad retaining bolts, this handsome pared-back bike is about as hill-climb specific as they come.
