I have a Tern Link C7 and plan on upgrading the crankset and free-wheel and make it a single speed. For those who are familiar with the C7's gearing, my question is: What combination of free-wheel and crank-set ring size(how many teeth) do I need to allow my bike to get up to speeds as fast as, or faster than it will allow now? I want to keep my top speed on my bike or increase it if possible. (@ about 26mph I begin to peddle too frantically to keep it up.)
I understand that the crank-set 'ring' must be large while the free-wheel must be small (mine is 52 for crankset, and 11 at smallest on the (7-speed) free-wheel). However I read the free-wheel should be as big as possible or it is more susceptible to damage and I want to avoid damaging it as I ride a lot. What gearing is optimal?
Also, what are a good crankset and free-wheel company? How are Retrospec all-stars? And can I upgrade their ring(teeth)?
ps. If you're offended by my post for some odd reason don't bother. I'm only looking for answers to my questions, and any explanations any can give.
