i noticed my chain was loose this week so i tightened it to perfection, i took it out for a half hour hard ride and its loose already, what the hell? i tightened all the bolts back on, a chain can't stretch that fast can it ? i'm gonna try to tighten it again and again, and hopefully it will stay

 

How much freeplay are you leaving?

 

unless your chain is shot, it should not stretch much at all, make sure u have
about 3/4 in. of slop in the chain. Torque the bolts to 35lbs without a hitch
& about 45lbs if u have a hitch. do not over tighten these bolts!! make sure
your bolts are in good shape & lube the chain, if it still keeps getting loose,
get a new chain and sprockets.

 

i left enough slack in the chain, it just kinda loosened right back to where it was before. I don't think i tightened the bolts back up enough. What should u torque the caliper bolt to, the one to the far left? i think i fixed it but i haven't been for a ride to see if it loosened again. thanks

 

caliper bolts are 12 lbs. for torque
