Shimano Ultegra 6700 Brake Caliper

Review from road.cc

Although it's great to look at new and shiny Dura Ace (and Di2) kit, it's always the announcement of the new Ultegra groupsets that generates the most excitement here at road.cc towers. Ultegra has always been the smart choice in the Shimano range: affordable enough to be a serious consideration with first dibs on all that innovation trickling down from the top.

Dura Ace 7900 was a fairly big leap in a market that mostly makes incremental changes, and Ultegra 6700 has stepped up a notch too, taking on plenty of the new technology at a price point that's much more within the reach of the keen amateur cyclist.

Ultegra now has the hollowglide chainring of Dura Ace. It also shares the internal lever cable routing, the Carbon lever blade, redesigned hood shape and repositioned pivots on lever and brake. In fact there's not much that it doesn't have, really only the no-trim shifting of the front mech. So what's the performance difference between the two groupsets?

Hand on heart I'd have to say that blindfolded I'd be very hard pressed to tell the difference between the two. There's no real performance advantage to be had by buying Dura Ace kit over the new Ultegra, not one you'll notice out on the road at least. The new Ultegra kit is excellent: shifts are crisp, braking is noticeably better, power transmission is near faultless.

In the end it all comes down to weight: Dura Ace 7900 is about 300g lighter than Ultegra 6700. If you can honestly say you'd notice half a pound more kit hanging from your frame then you need to consider the top-of-the-line groupset. For everyone else, myself very much included, the smart money's with Ultegra. Forget the RRPs for a minute: In the real world 7900 is going to cost you a grand, and 6700 can be had for less than £600. For me it's a no-brainer: if you're a Shimano fan then Ultegra 6700 is definitely the groupset that gives you the most bangs per buck. Here's how we rate the components...

There's lots of incremental changes this year but when you hear Shimano say they've upped the stopping power of the brakes in the wet by 100% then that's a grand claim. I'm not going to pretend that I've had the rolling road and the strain gauges out but I have been seriously impressed by the Ultegra 6700 callipers. There's a depth of stopping power there that's definitely a step above most dual pivots I've tried. Shimano say that the performance improvements are down to a repositioned pivot and a new brake compound. This incarnation of the brake also allows you to adjust the spring tension so you can tailor the feel. There's a multi-position quick release so you can adjust the pad clearance easily on the go, and the barrel adjuster is nice and chunky for gloved hands.

In conclusion...

Ultegra is the new amateur rider's benchmark for performance and price. Almost indistinguishable from Dura Ace in terms of performance, it only loses out on weight – but more than makes up for that in value for money.
