hello, i don't wanna mess anything up on this, there are 2 allen bolts on both side of the bearing carrier and on bolt in the middle of the bearing carrier. do i loosen the 2 allen bolts and tighten the one cent bolt until the chain is tight or what.

 

loosen the two bolts on the lower part, then there is a wheel on the left side of the carrier with spots for a tool tightner i just use a wrench and spin the wheel, this will tighten the chain

 

The little 10 or 12mm headed bolt doesn't need loosened to tighten the chain.

 

awsome i will check that out tomorrow
