Shimano is revamping its Ultegra group, cutting weight from the second-in-line road parts and, in trademark trickle-down fashion, incorporating many features that the company added to its Dura-Ace group last year.
The company claims that the new Ultegra 6700 group will be more than 150 grams lighter than the current Ultegra 6600 and 45 grams lighter than the Ultegra SL group.
The most noticeable changes are the under-the-tape shift cable routing, revised shift/brake lever shape, improved braking and improved shifting under load, thanks to a hollow large chainring and wider derailleur pivots — all features borrowed from Dura-Ace 7900.
The company did not release information on pricing or availability.
Shifters: The new shift/brake levers also feature carbon brake levers with reach adjustment and a revised brake lever pivot point to improve leverage. Shimano claims to have moved some of the shifters’ mass inward, toward the rider, saying that will improve bike handling.
The rear derailleur has an all-aluminum pulley cage to save a claimed 15 grams.
The cogset and new chain also are a claimed 15 grams lighter than the previous Ultegra group. The chain is asymmetric, like the Dura-Ace 7900 chain.
Brakes have a revised arch pivot location and a new pad compound said to improve wet weather braking. The cable stop has been moved down to improve routing.
The new Ultegra wheelset (model WH-6700) weighs 1650 grams and is road tubeless tire compatible.
Changes to Deore, too
The Deore mountain bike label now applies to two sets of parts, one for off-road and the other for trekking.
The group features a low-profile rear derailleur, borrowing technology from the higher-end XT and XTR parts. New shifters feature a 2-way release trigger and removable optical gear display.
The group’s hydraulic brakes have improved stopping power and now have the same brake pad shape as the SLX, XT and XTR brakes.
The E-Thru 15mm quick release hubs are now available in an SLX version.
The CS-HG61 cassette now comes in a 12-36 combination intended for use with 29ers. The cogs are: 12-14-16-18-21-24-28-32-36 and the cassette will work with any of the Shimano Shadow
design rear derailleurs.
