Shimano FC-RS510 11-Speed Double Chainset For 135/142mm Axle

Sleek and efficient, the Shimano FC-RS510 Double Chainset grants performance to any road bike using an 11-speed gear setup by being fully compatible with both 135mm or 142mm spaced rear dropouts, enabling optimal use with either rim or disc brake frame configurations.

The anodised crank arms offer a smart silhouette, keep the weight to a minimum and grant excellent pedalling efficiency, even during high power sprints and climbs. The drive side crank arm is mated to the oversized, 24mm diameter axle via a seamless, two-piece design to heighten rigidity and strength. This oversize axle configuration permits larger bottom bracket bearings (available separately) that are more efficient and durable.

Lightweight aluminium chainrings have chamfered teeth profiles to improve gear shifting markedly and provide silent running through even the most gritty conditions. The spacing of these chainrings is specifically formatted to work perfectly with bikes that have either 135mm or 142mm rear axle spacing. This chainring spacing also accommodates shorter chainstays.
