The Ribble Ultra-Road is an intriguing beast, designed primarily for riders who want to go fast on a bike that’s more comfortable than pro-level machines. While it doesn’t match the relaxed position of an endurance road bike, its geometry and material choices deliver on its promise of speed with just a little more comfort.

At first glance, the Ultra-Road is an aero bike through and through. The carbon fibre frame has been shaped and refined to reduce drag, from the flared, squared downtube to the flattened seat post and forks. However, closer inspection reveals a few concessions to a more practical approach to riding: the stealthily positioned mudguard (but not pannier rack) mounts, and enough bandwidth in the frame for tyres up to 38mm.

It’s still very lightweight for a road bike (8.2kg for the XL), and the frame is UCI-compliant. The frame also looks low-key spiffing, in a shade of deep grey with just a touch of glam-metal glitter. It comes in metallic damson and white, or any colour you choose (for an extra £350), plus there’s an option for a ceramic coat to keep it box fresh (for an extra £35).

Happily, Ribble has gone for a BSA 68mm threaded bottom bracket and a Universal Derailleur Hanger, which should please home mechanics.

Cockpit and groupset

Our review model came with aero upgrades, including a one-piece carbon cockpit with an integrated computer and GoPro mount. The cockpit comes in a variety of sizes, but it’s worth dialling in your fit before you buy, because there’s no going back without cutting your brake hoses.

We also got the Shimano Di2 12-speed model, with its crisp shifting delivered with the pleasing whizz of the electric servo motor. Other builds are available though. The bike starts at £2,599 with Shimano’s dependable 105 12-speed groupset, while the highest-end version, with Zipp 303 SW carbon wheels, SRAM Red AXS E1 wireless groupset, and a power meter, will set you back £6,999.

Final touches include bar tape that is just squishy enough and a Selle Italia SLR Carbon Superflow saddle which definitely isn’t squishy enough, but never became uncomfortable.

We also got the aero bottle cage bundle (+£35) thrown in, and there’s a neat little storage hatch in the down tube to accommodate your tools or bike elf.

The ride

A 100km audax taking in Wiltshire and Somerset proved to be the perfect testing ground for the bike, although I had to do a little explaining to ardent single-speed audaxers: that chunky down tube makes the Ultra-Road look more like an e-bike than a lot of actual e-bikes.

The Ultra-Road felt a little uncomfortable to start with, and noticeably stretched out. However, it all came together on flat, long, smooth sections, which is where the bike felt most at home. It wants to go quickly, and it wants to go in a straight line, to the point where it feels that the bike is leading you, and even trying to accelerate away from you, as you put the power down.

It’s a wonderful feeling, and there were certain cases where a tailwind was pushing me past pedalling riders. The build also inspires confidence: the stiff bottom bracket and even weight distribution help you feel like you’re magnetically attached to the road, and it corners beautifully with little more than a tap on the Ultegra hydraulic disc brakes for reassurance.

Of course, British roads aren’t always plain sailing, but this is a bike that doesn’t mind being chucked about a bit; it soaks up those surprise potholes that like to jump out and say boo, as well as distressed tarmac, without making you feel like your bones are about to vacate your body. On the open road, it delivers just the right balance of compliance and speed.

This is down to the geometry and the choice of wheels and tyres: Mavic SL 42 aero wheels cut through the air while proving relatively unflappable in cross-winds, while the 30mm Vittoria N.Ext tyres sit in the sweet spot between speed and comfort, and they didn’t pick up any punctures despite the absolute state of British roads. They come installed with inner tubes, but Ribble also supplies valves so you can go tubeless, which would make a lot of sense here.

While the bike felt completely at home on the UK’s shambolic road surfaces, it became sketchier on really rough terrain. The audax included 10km of canal path, and this uneven surface is where the bike struggled and became more uncomfortable, with my wrists and palms taking the brunt of the bumps. Room for wider tyres suggests that it might be able to handle this kind of thing, the geometry prevents any substantial off-roading.

It wasn’t just bumpy roads that exposed the Ultra-Road’s weaknesses – it’s not a climbing machine. Its long wheelbase (1026mm on the XL) causes an uneven, wobbly feel to the whole bike when you’re out of the saddle and pushing it hard. Thanks to the gear range (34t front and rear) you can usually sit and spin up hills, but the bits where the gradient increases or you need to dig deep can be unsteady.

It’s here that a discrepancy comes to light: the Ultra-Road’s wheelbase is 15mm longer than its faster Ultra-Race brethren. That may not sound like much, but the Ultra-Race is already a long bike, and stretching things further should be a recipe for discomfort. In the XL, the stack-to-reach ratio is remarkably similar, with the Ultra-Road coming in at 1.47 and the Ultra-Race at 1.44.

There might be a good reason for stretching the bike, though. Thanks to the Ultra-Road’s blend of carbons, over the Ultra-Race’s single material, the longer frame presumably gives the bike more leeway to soak up those rough roads without dropping speed, even if it does mean the bike handles more like a bomber than a fighter.

Ribble also shifts the rider sizing, recommending bigger bikes for smaller riders, and the Ultra-Road range tops out at a maximum ride height of 6ft 4in over the Ultra-Race’s 6ft 6in. From a purely theoretical point of view, a longer design makes sense, and it’s what helps keep the bike so unshakeably glued to the ground, but it’s also what makes it a wobbly climber.

Value

The Ribble Ultra-Road delivers on its promise of being a fast bike for mere mortals – it just does it in a roundabout kind of way. It’s most at home at the head of the pack on sportives or club runs, and I reckon you could squeeze an imperial century out of it – but you’ll be craving a cat/cow session when you get home.

If you fancy something that’s a bit more forgiving, the Scott Addict 20 (£4,299) is a close match to the Ultra-Road’s build, but its geometry is more forgiving and endurance-like. It might not be quite as fast, but its slightly more upright positioning delivers more comfort.

Specialized’s Aethos 2 (£5,499) is a similarly fast and comfortable bike, although it doesn’t offer huge aero gains, and you’ll need to switch out the lifeless stock tyres.

Finally, Cervelo’s Soloist sits in similar territory to the Ultra-Road, aiming for a light and aero bike that keeps the rider comfortable and happy.

Conclusion

I really enjoyed my time with Ribble’s Ultra-Road to the extent that the road.cc team actually had to prise my shoes from the clipless pedals to get it back. Initially, it doesn’t feel comfortable, and you will feel muscular tension by the end of longer rides. However, the middle part, where you need to reach blistering speeds for a sustained period, is so joyful that it makes up for some of the bike’s shortcomings.
