hi
i have bought a giant stp ss 2011 recently to ride street-trials but the gear ratio is really really anoying . specially when doing trials moves
crank : 28 t rear sprocke : 12 t
i wanted to change crank to trial crank but my friend said you must change the chain to trial too and it wont work with your rear sprocke .
im confused what i should do .. is it possible to change the rear sprocke too ?
