Fuji’s road range has for the last four years been under constant, ground-up redevelopment. The Track Elite with its wind tunnel-optimised design led to the TDF TTT-winning Norcom Straight time trial machine.

Lessons learnt from these gave way to development of the Transonic aero-road bike that impressed us at BikeRadar.

With the ultra-light SL arriving last year, finally the endurance-oriented crowd is catered for via the all-new Gran Fondo. Aside from its universal adoption of disc braking, Fuji’s design team, led by senior road product manager Steve Fairchild, have looked at every element of the GF’s chassis to improve comfort while maintaining swift handling from the SL and the stability of the Transonic.

The frameset is available in two versions. The higher grade 1 series uses Fuji’s C10 carbon and tips the scales at 940g for a 56cm, with the paired fork adding a further 370g. Meanwhile the second-tier 2 series using C5 carbon has a frame weight of 1070g, with the fork clocking 410g. See below for range details and pricing (AU$ figures were TBC at time of writing).

These figures are light for a disc-specific bike with endurance geometry; Fairchild told us the brand could have gone lighter, but explained that would have been at the expense of all-important comfort.

Road-buzz killer

That’s because both frame specifications use ‘VRTech’ material – seen here for the first time in a bike – in the seat and chainstays and through the fork legs. The VRTech process (it stands for Vibration Reduction Technology) uses a layer of polyurethane (PU) material within the carbon layup that Fuji claims vastly improves the frameset’s ability to absorb high-frequency, low pitch vibrations – that’s road-buzz to you and me. The VRTech does add 3-4g per layer, which amounts to around 24g per frameset – not exactly a big penalty to pay when Fuji has measured a 24.6% reduction over a non-VRTech frame.

Testing and proving the concept was conducted with two methods. The first was on road ride testing, with a bike equipped with accelerometers mounted at both hubs, and at the stem and seat rails. These recorded vibrations over mixed surfaces and offered direct comparison to gauge the effect of the frame. Both (VRtech and standard carbon) bikes were equipped with exactly the same components, with equal tyre pressures and the same test riders over the same routes.

The second test was lab based in Taiwan’s Cycling & Health Tech Industry R&D Center (CHC). The machinery here allowed Fuji to replicate plenty of road surfaces from the smoothest of tarmac to big potholes.

Its not just the VRtech wonder material helping aid the riders comfort though. Fuji has also designed new ‘Wave’ seatstays, which are kinked at the brake bridge position (though there isn’t a brake bridge, just a fender mount) to disrupt the energy path from impacts at the rear wheel reaching the rider’s hindquarters.

The bikes come equipped with 28mm tyres, though there is space to fit 30mm with mudguards (fenders) and, according to Fairchild, a high percentage of 32mm models will fit too. Fairchild told us he believes 30mm rubber is the future for endurance-style bikes, as the increased comfort pays dividends – especially over long distances.

The disc specification means Shimano flat-mounts plus 12mm thru-axles front and rear (surely 12/12 is set to become the default for road bikes). Interestingly the rear 12mm thru-axle is convertible: with the removal of a single 5mm nut and bolt on both rear dropouts you can remove the threaded thru-axle section and run a standard 135mm QR rear wheel, should you wish.

To ensure the balance of the bike’s rear end the chainstays are highly assymetric, with the non-drive side significantly beefier than the drive side to handle the extra forces upon it from the disc brake.

Size-specific geometry, women’s version in the pipeline

We like that Fuji has built in year-round versatility with the additional of concealed mudguard mounts, with each bike including a set of add-in stainless eyes to fit full length front and rear ’guards.

The ride position is as you’d expect taller at the front and shorter in reach, with our 58cm test bike having a 625mm stack and a 389mm reach. The steering geometry is the same as the race bred SL.

The gran fondo's geometry compared to the sl – it's a little taller, a little shorter in the top tube, but a bit longer in wheelbase:

Fairchild went on to explain that Fuji has introduced an ‘optimal range of trail’ too – in other words the trail figures are size specific (to avoid any potential toe-overlap). So on the XXS bike that’s a trail of 61.7mm on a fork offset of 52mm, on the XXL its 58.7mm on a more standard 43mm offset. Like all Fuji road machines the tubing diameters are also size specific to ensure parity in ride feel across the board, so the (down tube) diameter ranges from 52.3mm on the XXS to 57.2mm on the XXL.

Fuji also announced a women-specific version called the Brevet to launch soon. Alongside the components being female-friendly (slightly narrower bars, women specific saddles) the developers have also adapted the tube diameters, and size for size they are slightly smaller than the men’s versions (because female riders tend to be lighter than their male equivalents). The top-tube lengths size for size are slightly shorter too.

Further models are on the way including flat-barred versions and a range-topping model equipped with SRAM’s wireless Red eTap groupset. The frames already come with injection moulded cable stops for mechanical, Di2, and flush-fitting blanks should you want to forgo cables all together.

First ride impressions: precise handling and tingle-free fingers

We took the Gran Fondo 1.3 for a spin over a mountainous test route in Taiwan. While the road surface was generally good, over speed bumps, bridge expander sections and some rain-scarred tarmac the 1.3 seemed truly impressive. Now, any bike running fat rubber on nicely wider rims like the Oval 723s we’d expect to be great, so to see if the frame really lived up to its claims we banged the pressure up to a way-over-the-top 110psi.

Still the overall impression is a chassis that’s as good at isolating you from irritating road buzz as anything I’ve tried without the aid of suspension. The slightly more upright position than I’d usually ride did at first feel like a bit of a compromise; on the rolling terrain of the first third of the ride I really had to hunch into the drops to get a faster position.

The 1.3 model is based around shimano's ultegra di2 and r785 hydraulic brakes, sadly this model won't be coming to the uk: the 1.3 model is based around shimano's ultegra di2 and r785 hydraulic brakes, sadly this model won't be coming to the uk

When we hit the mountain climbs however the ride position felt ideal, natural and easy on the lower back. Once we’d crested the rise and into a 10km-plus hairpin descent the 1.3 was brilliant in the drops – the perfect mix of power and feel coming from the superb Shimano R-785 brakes and the formidable grip from the big Vittoria slicks only being topped by the stability of the extended wheelbase and the light, swift and precise way the bike steers.

The equipment looks like decent value too. The shapely Carbon Oval Ergo 910 bar has a big oversized shape to the tops, with the opening-out shape of the ergo drops offering plenty of room for even the biggest shovel-hands. Out back the carbon post is a fine match for the frame, with enough slender mast exposed to add a bit more compliance. We even liked the narrow (yet well padded) Oval 700 saddle.

The 723 disc specific wheelset, looks pretty understated and, if anything, seems a little modest on a Di2-equipped bike. But as mentioned above the wider rim suits the big volume tyres and they didn’t flex or creak under pressure, and handled well in a section of blustery crosswinds.

Once the ride had finished Fairchild had waiting for us an equally equipped bike, with the same 110psi in the tyres and the same frame material (sans VRTech). We jumped straight onto this unmarked mule, and rode back up the final descent and then back to the finish.

Honestly the difference was marked – on the production bike this section felt smooth and slick, while on the mule halfway down the steep twisting descent we had that telltale tingle in our hands. Elsewhere bike the difference was less drastic, but that probably had more to do with the punishing climbing we’d done over the previous few hours.

In all the Gran Fondo impresses, though the short and tall geometry won’t appeal to racing snakes, even if the handling is spot on. The comfort levels afforded by the frame though should be welcomed and positively encouraged, whatever your particular peccadillo is. We can’t wait to get a GF back on UK soil and treat it to some truly bad road surfaces to see if VRTech really is the cure for tingling fingers we think it might be.
