I have a new coaster-brake bike with an aluminum frame and forward-facing slotted dropouts. I'd like to buy an axle tensioner. I purchased an Origin8 brand one, but it won't work There are two flaws:

1. The slot in the rear of the tensioner is not wide enough to fit over the wider aluminum dropout

2. The bolt in the tensioner is not long enough to reach the rear of the longer aluminum dropout

I may modify the tensioner by filing out the rear for sufficient clearance. I may then add a link to the chain so the axle will sit further back in the dropout (this might make the bolt sufficient to reach the rear of the dropout).

Rather than do this, though, I'd rather buy a tensioner that's designed for aluminum frames. Anyone make one?

PS: Note that I do NOT have the rearward-slotted "track" dropouts on this bike.

Thanks - FH
