Q & A

The new Shimano Ultegra HollowTech II 10-speed compact chainset benefits from the technology pioneered by the flagship Dura-Ace groupset. Offering the optimum balance of light weight and rigidity, making it the perfect choice for both competitive and enthusiast riders. 

Shimano has raised the bar to a new level of performance with the development of a hollow outer chainring, giving vast improvements in rigidity and increased weight savings. The hollow outer chainring has essentially removed outer chainring flex, hugely improving shift performance making it precise even under high load.

The chainring teeth have been developed to work only in conjunction with the CN6700 chain for improved contact providing more efficiency and improved power transfer. This 50-34T ratio compact crankset is available in a wide range of crank arm lengths to suit all riders and racing disciplines.

The HollowTech II integrated bottom bracket design uses a wider bearing placement and larger axle diameter for increased stiffness and efficiency. The bottom bracket's seal design has a minimal bearing interface giving superbly smooth rolling and increased durability.

Weight including bottom bracket 785 grams.

Note: Supplied without bottom bracket cups which must be purchased separately, See accessories below.

New Ultegra has been developed significantly to offer a greater level of performance, offering many of the features from the top of the range Dura-Ace groupset. The design of the Ultegra 6700 series is centred largely around improved aerodynamics and weight saving with upgrades across each component. The most striking differences however are the HollowTech II chainset, and redesigned shifters with hidden gear cable routing, features previously exclusive to Dura-Ace.

Ultegra is available in a wide range of component options including Double, Triple and Compact to suit all kinds of road cyclists, from the enthusiast to the elite road racer.

Ask a question In relation to the crank length, forgive me for being a novice but I'm looking to upgrade my groupset from Tiagra to Ultegra on a month by month basis (I can justify this to the wife this way.....can't be doing with earache)she can spend 200 on hair and beauty treatments every month, but spend money on upgrading my bike...!Anyway, you've already answered my last question on upgrading to Ultegra brakes, thanks for that, could you please advise on crank length as in where to measure to and from.RegardsJoe Johnson (1 Answer)
Ask a question One further question relating to crank/bottom bracket. I have a BB30 bottom bracket on my Cannondale, could you advise on suitable bottom bracket cups as it states these are not supplied with the crankset. Many thanks Joe (1 Answer)
