PROTYPE - 68 x 109mm ISO Taper BB!!!
The number one question/email we get is..."Does anyone offer a reasonably priced sealed cartridge bottom bracket for the Sugino 75 track crankset, a true 109mm ISO taper bottom bracket?". The answer for a very long time was unfortunately "no".
Well, after searching high and low (for what seems like a millennium)we found a manufacturer!
