• Uni-band clamp fits 34.9/31.8/28.6mm seat-tubes with included shims
• Convertible between top-pull and bottom-pull cable routing in either low-clamp/top-swing (TS) or high-clamp/down-swing (DS) configurations
• For 65-71 degree chainstay/seat-tube angles (most common)
• Designed for 54.3mm chainlines (83mm-shell/150mm-dropouts) with a 165mm max bashguard diameter (for 68/73mm shells with 50/51mm chainline, use SLX-M665/667 offerings)
