i recently upgraded the the cog on my new mercier kilo tt, it was a 16t and now i have a eai 17T installed (http://cgi.ebay.com/ws/eBayISAPI.dll...=STRK:MEWNX:IT).
but now the chain is too small for it, what size chain do i get now? because when i put on my rear tyre, it wont let me pull the chain back to make the chain not loose. HELP PLEASE?!?!
