Tom Booth Posted July 21, 2005 Report Share Posted July 21, 2005 (edited) So, is 20T not advisable on the GU frame then?? ← Yeah you can still run one, but it wont need a 127mm bb it could use a lower length as the ring is smaller, it wont need as greater clearence on the yoke, so the bb ca be smaller :S Edited July 21, 2005 by Tom Booth Quote Link to comment Share on other sites More sharing options...
totaltrials Posted July 21, 2005 Report Share Posted July 21, 2005 I think you can get away with 122 bottom bracket if it's ISIS you can space the cranks furtehr out if you need to, a 128 is always best no matter what chain ring you have, but I think either of them 122 or 128 will be fine.
