Gearbox chainring

For more ground clearance while mountain biking, we recommend the 24T sprocket. For touring, we recommend the 30T sprocket. Available in 2 sizes. 

Chainline: 50 / 54 mm

For maximum durability, selected sprocket sizes are also available in the Longlife version! A comparison of regular (left) vs Longlife (right) version is below.

Longlife

Extra-sturdy sprockets with 1 mm wider teeth. The Longlife sprockets are designed for use with ½”x 1/8 chains with a total width of up to 8 mm. Use only in combination with X101 Longlife chains. Only get a longlife part if all the rest of your sprockets are longlife-compatible.
