SHIMANO CENTERLOCK LOCK RING SM-HB20 – SECURE MOUNTING FOR YOUR BRAKE DISCS
The Shimano Centerlock lock ring SM-HB20 is the reliable solution for mounting your brake discs on Centerlock hubs. This version features an external spline that is installed with common Hollowtech II bottom bracket tools. This offers the necessary space and excellent power transmission when tightening, especially with axle standards with larger end caps (e.g., 15 mm or 20 mm thru-axles).
Made from robust material and including the matching washer, this lock ring guarantees a permanently secure fit for the brake disc. Thanks to its flat design and precise splines, it is compatible with all common Shimano Centerlock brake discs. Weighing only approx. 9 g, it is also a lightweight yet highly stable choice for your XC, Road, or Gravel setup.
