Need to replace my lower chain roller on 05 ec250 and want some opinions. I have a TM Designs on my Honda and the plastic is so hard that it doesn't seem to always roll...chain just slides over it. This happens quite often if its wet and muddy. Even though it slides it still has little to no resistance. Anyone using these in their gasser? Stock one is a bit cheaper and will fit. I haven't seen a TM Design lip roller for this bike. Bike already had TM Design chain slider and chain guide installed when I got it. Any other option out there that has worked well? Thanks.
