sprockets....i'm lost

FMYStreetRacer · 01-03-2007, 09:09 PM

i need to order sprockets for my Roketa db-07a. anyone know what chain this has by any chance? i'm guessing it's a 520 chain? i'm looking at the jtr279 sprokets and i'm thinking of going with a 15 tooth front and a 42 rear. this sound about right for street/trail use? it will be used on the street more than the trail.

or i could go with a 14/39 and be about the same ratio and still have allot more room to play with by playing with just the front. i'm very lost in all of this. i also don't want it to tear up my chain gaurd to bad.

if anyone can help me please do. thanks.

Edit: ok now i'm almost sure that my chain is not a 520 but a 428. all the 428's are offered in higher numbers (like what i have on my bike 17/56) so i think i'm just going to order a 44 tooth and see how it does. maybe a 42 will come later on.

Edit #2:

i ordered a jtr 269 44 tooth rear sproket from bikebandit.com. can't wait to get it on the bike.
