Although the crank arms and spider arms are noticeably bigger, which increases stiffness, the overall weight of the Shimano Dura Ace R9100 chainset has dropped by 7g over the previous edition of Dura-Ace. Shimano has adapted the crankset to work with disc brake road bikes that generally have 135mm rear hub spacing and shorter chainstays without the need to increase Q-factor thanks to its wider chainring spacing. The double version offered here comes in numerous gear combinations to best suit each individual rider's needs. Please note: Bottom bracket is not included.
Shimano Dura-Ace R9100 11 Speed Road Double ChainsetThe Shimano Dura-Ace R9100 11 Speed Road Double Chainset boasts Shimano's well-known 4-arm hollow spider that is constructed from hollow-forged aluminium. This chainset has been completely redesigned to ensure it boasts the best combination of lightweight and rigid construction. The chainset has been adapted by Shimano to work with disc brake road bikes that have a 135mm rear hub spacing and shorter chainstays without the need to increase Q-factor thanks to its wider chainring spacing.

Already a legend in its time, the SRAM Red Exogram Crankset is now available with refreshed graphics to compliment SRAM RED eTap components. The SRAM Red Exogram crankset features a completely hollow construction all the way to the spider. It's hidden bolt pattern makes better use of carbon fiber to further improve stiffness and shed weight. As always for seamless, flawless performance and Yaw compatibility, the chainset has been equipped with X-GlideR chainrings. The chainrings are designed for an optimised shifting performance with the Yaw front derailleur. The stiffer rings (5mm 7075-T6 aluminum CNC-machined) feature upshift rivets with an advanced design adopted from SRAM XX. CNC machining allows for precision control of each tooth shape, ramp, and nearly every shifting feature of the chainring. Chainrings, chain, and front derailleur are designed as a single integrated system for optimised performance.Arm Material: CarbonChainring Material: AluminiumBottom Bracket: GXP (Not Included)Weight: 609g
