he Shimano Sora Chainset features a compact chainring design for 9 speed drivetrains, offering excellent value, this chainset is ideal for training or riders taking their first steps into road cycling. The 2-piece cap-free design is quick and easy to install, whilst being lighter and stiffer than a traditional crank/ bottom bracket assembly.

The aluminium crank arms are combined with compact 50 or 46 tooth alloy and 34 tooth steel SG-X chainrings which feature strategically placed chain pick-up pins and tooth profiles to ensure fast and positive shifting.

Designed to work with HollowTech II type bottom bracket cups (not included) and compatible with 9-speed HG chains. Chainrings use a compact Shimano 110mm bolt circle diameter.
