stu t Posted September 21, 2010 Report Share Posted September 21, 2010 (edited) I'm looking at using a 4bolt mtb chainset on my stock GU to replace and Onza Orbita but I need a small diameter bashing. Can anyone recommend anything? The DMR ring thing inner looks ok but I can't find anywhere stocking a 4 bolt version. I've also found a Backside Granny in 4 bolt but can't find the diameter anywhere to check if it will clear my frame. Cheers.
