Hi!

My stock Kilo TT has 48t/16t chainring/cog. I would like to upgrade the gear ratio for more skid patches, and lower ratio. I'm thinking upgrading the chainring to 45t will be the best bang for the buck. In my search, I found the Shimano Alfine S501 45t chainring for $26+$9shipping. http://goo.gl/e80jkv It's very hard to find a 45t chainring.

Would the above chainring work with my stock chain, and stock crankset? Any downside to having an odd number chainring tooth count?

Thank you!

I'm assuming and hoping I won't need to replace the crank bolts.
