Shimano Fc-7900 Dura Ace Double Chainset 170mm 39/53t Description

The hollow outer chainring has essentially removed outer chainring flex, hugely improving shift performance making it precise even under high load

These industry leading HollowTech II cold forged hollow crank arms have been evolved to increase rigidity, reduce weight, and improve strength

The teeth have been developed to work only in conjunction with the CN7900 chain for improved contact providing more efficiency and improved power transfer

There is a wide range of chainring ratios and crank arm lengths available enabling customisation for all riders and racing disciplines

HollowTech II integrated bottom bracket design uses a wider bearing placement and larger axle diameter for increased stiffness and efficiency

Bottom bracket seal design has a minimal bearing interface gives superbly smooth rolling and increased durability

Weight including bottom bracket 725 grams

Bikes

J E James Cycles stock a wide selection of bicycles across all cycling categories including road bikes, commuter bikes, BMX, Mountain Bikes, XC, downhill, electric bikes and folding bikes. Most cycles can be bought in store and online, although there are exceptions with certain bike brands, where the bicycle can only be collected in store. These bikes are clearly labelled online where the bike is added to the shopping basket.

Prior to dispatch, all full sized bicycles are assembled and inspected by our qualified Cytech mechanics. These bikes will then be partially disassembled and placed in a cycle box ready for shipping. On receipt of your bike some assembly will be required, which may include attaching pedals, front wheel, seat pin, handle bar and stem. Single speed kid's bikes and BMX bikes will be shipped by J E James Cycles as they are received from the manufacturer. Customer assembly will be required.
