Hi! Would you mind telling me what mech you swapped to or use, fossala?
(My first post to the forum.) I have a Micro that I haven't ridden for a few years and I'm getting it back on the road again. One ride so far was super fun. The previous (replacement) mech got very close to the ground, enough to eat grass if I cycled across a long lawn. So I did the tooth difference calculation (41) and ordered a Tiagra. To my annoyance it was the same length as the existing Deore. I suppose it originally was fitted with a shorter cage mech with the instruction never to use the big ring and big cog together. I basically need a shorter mech so that the chain and arm don't get too close to the ground.
Secondly, I see that you seem to have a shorter amount of tube that the chain runs through to keep it off the ground. Mine has a longer tube and one support pulley. Have you done any adaptations there? do you run a really skimpy chain length? Coming from other bikes there is quite a lot of noise from the chain through this tube. Thanks!
