Hey guys. Just gone to fit a single pinch 401 and found that my sugino spider doesn't fit as the spindle section of the arm is a different level to the chainring mount if that makes sense?
There's a small lip on the chainring mount, so I'm guessing that a specific Redline chainring / spider fits onto this to level things out.
Anyone got any ideas? I've bought s sugino spider, bolts and chainring so may have to try and trade or replace.
Thanks
