The little brother of Shimano's high end road cranks has really come into its own in the most recent generation of 105. Featuring Hollowtech II crankarms and Hyperglide ramped and pinned chainrings, it shifts nearly as well as the Ultegra or Dura-Ace cranks with just a bit of a weight increase. If you''re a beginning competitive road cyclist, 105 is one of the best componentry lines money can buy, hands down.
- 7075 aluminum Hyperglide chainrings with ramps and pins
- Hollowtech II bottom bracket spindle and crank arms for increased stiffness and reduced weight
- Weighs in at 910g
