I've been riding using only one gear since that first post. It's really great, not having to think about shifting. But, as a temporary fix, how would I go about adjusting the limit screws to keep it in one place? I fiddled with them a bit but I can only seem to keep it in the 2nd smallest cog (16t) or the 1st smallest (14t) , and those gearings are a bit too much for me.
