i also want to swap my rear sprockets on both my bikes. i have 530 chains and other than that what measurements do i neeed to check before i buy them?  i think i would like to try a 38 or 39 on my long bike. and maybe a 43 on space truck'in. i am mainly concerned about highway riding as i would like to keep up better with larger engine bikes on all day rides. so do yall think the 38/39 would be my best bet? dose a 43 make much differance on highways riding?
damageduck what do you want for the39 and do you have others so i could get them both from you to save shipping?
johnnycakes what do you want for the 38?  thanks
