Acros AI-22 Stainless Block Lock
Acros AI-22 Semi-Internal headset
The latest innovation from ACROS is the BLOCK LOCK System. We've integrated a steering limit to prevent you from frame damage due to handlebars or forks. This makes our Block Lock especially useful if you have an ultra light weight carbon frame. Cutouts in the upper bearing shell guide the pin of the headset top cap and limit the steering in a mechanical way. The forces will be reduced by elastomeres to increase the grade of protection for your frame. The basis for our BLOCK LOCK system are our proven ACROS headsets AH-06 and Ai-22. Both use high quality stainless steel bearings and our proven R3 seal to guarantee you a long lasting performance. For the positve locking between headset and stem / steerer is guarantied by our special locking spacer or our ACROS BLOCK LOCK compatible A-Stem.
