I have recently replaced my chain as the previous one had worn to just over 0.5% (measured with a vernier so hopefully I got it right). This was my first chain replacement (the bike was new) and I didn't replace the cassette or chainrings as they did not appear to be sufficiently worn. I'm unsure of total mileage but it was probably about 2500-3000k. Almost immediately when putting down some power the chain slips and often jumps off. I have since cleaned off the factory grease and lubricated with the oil I normally use but the problem is just as bad. I can't say exactly where this is happening but I think it is the bigger chainring because the problem does not happen when I am on the smaller ring. Could the larger chain ring be too worn with so little mileage? It really does not look bad (the teeth are a little flattened from riding over rocks, etc but their shape still looks good) and none of the teeth appear to be bent. Components: Chainring: Shimano XT FC-M785 28-40T (2x10) New chain: Shimano XT HG-X 10 speed Cassette: Shimano XT 10 speed (not sure of ratios) Has any-one experienced something similar?
