Thanks GN...the chain tensioner is installed. It is a little loose, it's 8 mm chain & it really doesn't look that durable to me, but I guess that's what racing chains look & feel like. Had to find another gear box because the gb that came with the kit was trashed (broken shaft). Couldn't find a cost effective alternative so I went with Dax's set-up. The set-up performs well...it's alot quieter and almost 1/2 the size of the stock gb. I've gotten up to 33mph on the flats which is amazing to me weighing 224. You do have to peddle to get going though and it doesn't take hill climbing at all which in my case I need. I did a 25 mile ride and it was fun but the next day I was all stiff and hurting. How do you say ADVIL?How well does the DAX race box perform? Are you going to install a chain tensioner on the left side chain? It looks awfully loose in the pictures.
