Product Details

Shimano 105 5800 Chainset

The Shimano 105 5800 chainset offers key features proven at Dura-Ace / Ultegra level such as HollowTech 4-arm cranks and 11-speed compatibility.

The chainset is reinforced around the chainring area to create a pair of cranks which are more flex resistant despite their lighter weight.

  • Shimano's innovative HollowTech forged, anodised, aluminium crank arms are indeed hollow and noticeably lighter weight.
  • The chainring teeth have been developed to work in conjunction with Shimano HG-X 11-speed chains for optimal contact to maximise power transfer and drivetrain efficiency.
  • The HollowTech II design employs a wider diameter axle and larger bearings set wider apart to create a chainset that is more flex resistant, more durable and lighter weight.
  • The lightweight anodised SG-X aluminium chainrings deliver smooth, precise shifting.
  • The integrated 2-piece design makes for easier installation, adjustment, and maintenance.
  • Can be used with Shimano external or press-fit bottom brackets (BB not supplied).
  • Weight: 742g - based upon weighing one Shimano 105 5800 Chainset with 50/34t rings and LH crank at Bike Co-op HQ in May 2015.
  • Be aware that cycling equipment specifications can change without notice so please regard our published weights as an honest but approximate guide.
