hey guys whats up today? my ?is on my 88 racer im running 18/11/8 tires on the back and its geared to low i believe i have 11?42 gears what should i be running or what do the other people run with this size tire . generally i play race and generally ride pretty aggressive. thanks for your help guys

 

IMO I think you should bump the 11 up to the stock 12.

 

Try both the 12 and 13 in the front. I think most people bounce back and forth between the 12 and 13.

 

i went from 11 too 13 and it gave me lots of top but did not sacrifice alot of bottom... good for all around riding IMO
