sprocket specialists are good, the front and rear are easy to install but if youre making a big change ull hafta take it somewhere to get the chain done, at least i do

 

I am switching mine to a 15/46 and going with RK chain and sprocket brand. I got mine on Ebay. 129.95

 

I recently ordered the 520 conversion - Q/A kit from the local shop and after I paid, found out that the kit is on back order from the manfacturer! I have waited for about 2 weeks and the shop called yesterday to say that it has been shipped and they should be getting it in tomorrow! Can't friggin' wait to get it on the bike.
