Some do, some don't, it depends on the rod used in the cranks, I have just fitted a 62/115 that hardly needed anything trenching out, yet I've fitted five 60/110 cranks in the last few weeks that all needed lots trenching out.shocky wrote:My 60 crank fitted no probs as does my 58/110
the 62/115 ive just fitted has had the rod changed for a better one with a better bearing, with the standard rod in that crank a lot more trenching is required.
