Shimano 105 is a by-product of our premier engineering range but has its own unique identity, offering a greatly enhanced and sleek design that's backed by a high performance. The Shimano 105 design concept of "smooth, Round and Natural" is consistently demonstrated in every component, giving its user a sense of satisfaction and pleasure.
The Hollowtech II crank and bottom bracket combines race-proven hollow forging technology with the integrated crankset & bottom bracket. Weight is reduced while rigidity & power transfer is radically increased. Finished with SG-X chainrings which enable super smooth shifting. The rings use special tooth profiles, pick-up spikes and ramps to help make the front derailleur shifts quiet, easy and trouble free for you the rider.
Shimano road chainsets do not include a bottom bracket, you will need to order this separately to suit your frameset
Innovative HollowTech forged and anodised aluminium crank arms utilise a hollow design that minimises flex and keeps the weight low
HollowTech II allows the bottom bracket bearings to be spaced wider apart (outboard from the frame), enabling the use of larger bearings and an increased axle diameter
The system allows for easier installation, adjustment, and maintenance
Lightweight anodised SG-X aluminium chainrings for smooth and precise shifting
