Thanks Shane, looked at the M3, nice reviews but I’m more leaning toward the Cycleops and btw Cycleops is the most expensive one among the 3 hahaha, which proform you have, it seems the early versions gen 1 and 2 have more issues and it’s been claimed that the centennial has resolved all, not much reviews available on the latest one though, time will tell, still waiting for Hall cycle guys to give me the price of the cycleops.
