Information

With all the different bottom bracket styles, frame manufacturers, and component makers out there you’re bound to run into situations where spindle spacers may be needed to make your particular frame/crank/bottom bracket combination fit correctly together.  Because there’s no way for us to know what your particular situation might be, we offer “kits” to cover a wide variety of combinations.

We offer three spindle kits for 24mm, 29mm and 30mm spindles.  The 24mm and 30mm spindle kits also come with one “wavy” washer which goes on the spindle and acts as a bearing “preload” mechanism for crank arms that do not use a built-in bearing preload adjuster.
