Description
These conversion kits fit hubs which were used on a lot of older wheelsets (up to 2016 or so). Current 6-bolt standard spacing hubs are the 3-in-1 which converts up to 15mm (not 20mm) and uses different end caps.
These end caps do fit current fat bike hubs, use these for 135mm and 150mm fat standards (135 qr, 135×15, 150×15 etc)
