Ribble R872 Ultegra Di2
8 10

Ribble's R872 is a really solid package for anyone wanting to ride quickly without handing over life-changing sums of money. This Shimano Ultegra Di2 build just sneaks over the £2,000 mark and for that you're getting a very responsive frame and fork, excellent groupset, decent finishing kit and some okay wheels. The R872 handles really well and it's easy to get on with, save for a slightly harsh front end. For the money it's easy to recommend.

The R872 has been in the Ribble range for years but this year's bike is a new design bearing the same name. 'Our challenge was to improve our best-selling carbon road bike,' says Ribble on its website. 'How do you actually improve an already perfectly balanced bike? The R872 has been so popular with road racers and triathletes alike that we listened to their needs for an even stiffer and even faster ride.'

Reading that, you'll not be surprised to learn that stiffness has been beefed up over the previous incarnation, and if you're a fan of percentages then you're going to like this paragraph. Stiffness gains include: Fork (in-line) 16.4%; Fork (lateral) 26.5%; Head tube 8%; Bottom bracket 15.4%; Chainstays 14%. So, then: stiffer. There are also some marginal gains in aerodynamics from a redesigned fork and head tube, and the new bike uses carbon dropouts instead of alloy inserts. The geometry remains the same.

The ride reflects the stiffness numbers. The R872 feels very solid from the get-go, and the massive press-fit bottom bracket shell and beefy chainstays transmit all your leg power to wheel rotation without any mucking about. Even properly stamping on the pedals doesn't elicit any flex. It's the same story at the front, with the fork tracking extremely well. The steering feels precise and predictable, it's not a nervy bike at all.

One of the downsides of all that stiffness is that it very efficiently transmits road shock through the bike. It's most noticeable at the front: the bike doesn't glide over rougher surfaces and you get a thorough commentary on what's going on at the contact patch through your hands. Our test bike had a standard Deda Zero 2 alloy cockpit and cork bar tape; the R872 is fully customisable through the advanced bike builder on the Ribble website and you can spec a more expensive bar and better bar tape when you order it. I'd certainly recommend fitting the nicest bar tape that Ribble offers (Fizik Performance Soft Touch would be my pick); whether spending more on a posher carbon bar is worth the extra £120+ is a bit more of a marginal decision.

Comfort at the back isn't bad at all. The frame is reasonably compact which means there's plenty of seatpost showing, and the standard issue Superleggera carbon 'post does a really good job of taking the sting out of the surface. Less so the Selle Italia Flow X1 saddle, which isn't one of my favourites – but again, there are lots of options to choose from at the point of order.

Road and race track

I've thrown the R872 at a range of riding and I've been very pleased with the way it's performed. On two 100km loops of the Mendip hills it was a very capable and reliable companion. The bike doesn't have any vices: it's happy to cruise with minimal input, and if you do want to put the hammer down will jump to attention. It's easy to keep your momentum if you're riding quickly, with the Ribble eager to respond if you put in a dig to get over a short rise.

Once you get onto a more sustained climb the R872 is very competent at clocking up the metres of ascent. Seated climbing feels unflustered and the bike is comfortable when you're keeping most of your weight on the saddle; on steeper and looser climbs the bike sometimes scrabbles a bit at the front, but it's rare.

Out of the saddle the Ribble can feel a bit skippy over rough back road surfaces but up a well-surfaced climb it's very well behaved and you don't feel like you're wasting any power. The Fulcrum Racing Sport wheels are the only thing on the bike that's really a budget option, and at around 1,900g they're stolid and dependable, rather than lively. There's nothing really wrong with them though, and if you wanted lighter wheels you might be better off buying them separately, depending on your choice: upgrading to Shimano's RS81-C24 wheels will cost you £400 when you can buy a set for about £30 more than that, whereas swapping to Mavic Ksyrium Elites is a £300 upgrade and they're about £475 to buy online. If it was my money I'd probably spec Fulcrum Racing 7s – which are £40 more than the Racing Sports but significantly lighter – and save up for a posh wheelset at a later date.

I also took the R872 racing down at the local crit circuit. I didn't do very well, but that's par for the course right now, rather than being anything to do with the bike. I had to disassemble the headset and regrease it to get rid of an annoying creak (that I thought for a long time was the bottom bracket), so I took the opportunity to slam the stem for a more aggressive position. With a stack-to-reach ratio of 1.45 in the XL size tested the Ribble is not quite as nose-down as the Boardman Road Pro SLR (1.41) that I normally race on, but I didn't feel like the position was too upright for mixing it in the bunch.

The super-stiff frame and fork respond very well to being thrown into tight corners and then punched back out of them to try to hold a wheel; the heavy wheels take a bit of edge out of the bike's response when you're mashing the pedals to try to stay in the race, but if you were planning to race the R872 on a regular basis you'd probably want to roll on something lighter and more aerodynamic than stock wheels.

Shifting opinion

Shimano's Ultegra Di2 groupset is a firm favourite here at road.cc. 'With all the performance of Dura-Ace at half the price and with a weight penalty that only weight weenies could worry about, Ultegra Di2 steals the show,' said Dave Arthur in his review of the groupset back in 2014; there's been a lot of water under the bridge since then but Ultegra Di2 is still holding its own out there. There's a new Ultegra R8000 groupset coming, but you'll still be able to get bits for this groupset for many years to come.

Functionally, the groupset gave no issues at all, shifting precisely and accurately every time, even under heavy pedal load. The front shifts are especially impressive when you're putting the power down. I don't personally think that the ergonomics of the shifters are quite as good as the other two electronic systems – SRAM Red wireless is my favourite, and Campagnolo EPS is good too – but there's no issue with the performance. The dual pivot brakes are very powerful and were a bit grabby on the shiny alloy of the brand new Fulcrum wheels, but things settled down there after about 100km and now they're both effective and predictable.

Conclusion

So who should look at buying the R872? Ribble's sales pitch is at the privateer racer and triathlete, and certainly if you want to race you're getting a lot of bike for the money here. If you're not interested in pinning a number on your back but you still want to go quickly at the sportive or against your mates then it's a great bike for that too: the R872 is fast and agile, with a stiff frame and precise steering.

The spec for the money is about as good as you'll find, and the Ribble Advanced Bike Builder gives you a huge range of options if you want to customise your bike.

If you're looking for a bike to ride fast, and value for money is high on your list, then this Ribble should be high on your list too. You can have the R872 with a Tiagra groupset for under £1,100 if you pick the cheapest options but you'll do better to spend a little bit extra on the wheels and finishing kit for a better all-round experience.

This build, with Shimano Di2 and Fulcrum wheels for £2,065, is a compelling package. I'd change the saddle and bar tape and fork out a bit more for the next wheels up in the range.

Ribble says: "The R872 is our signature carbon road race bike. New for 2017, our next generation R872 has been made stiffer with updated tube profiles and advanced carbon layups as well as gaining increased tyre clearance.

The Ribble R872 is a performance, race-bred, road bike. It has been technically engineered to optimise power transfer, meaning less energy is lost through frame flex. With the short wheel base this keeps ride handling precise and agile.

The R872 is now available in stealthy Matt Black and a new Matt Silver colourway.

Great value package, and a fast riding and purposeful frame. A bit harsh through the front end, but it's designed to go fast and it does that very well.
