hey so i was planning on going riding this weekend but i changed the front sprocket for a smaller one. problem is now i got a crapload of slack in the chain. turns out the idiot that used to own it conveinently stripped the chain tensioners in the place where they needed to be so it worked for now. but now i need to tighten the chain up so i can go riding this weekend. any ideas of how to rig it up so it will at least work for now? thanks in advance
