so I was out having fun in the slush and snow on my STP (w/hookworms!) when all a sudden I was slammed into the stem! the deraileur hanger snapped off clean, jamming my tensioner between my CS and tire. Very sad, no STP hangers in town and if i could find a 34 tooth chainring I could have a magic ratio. No rings either.

Now i'm thinking the frame was only 400cdn, I could file the drop outs just a bit and run my current 36x18 tentionerless, question is. how should I do this? Rat tail file? Dremel?
Anyone try this?

I have done it before. Use whatever you can control the easiest. You don't want to remove too much...

File the axle, not the frame.

I remember a thread about that a year or more ago. I was ready to do it when a wheel switch solved my problem. But, you can replace the axle on your wheel easier that any material removed from the frame. Do a search and then give it a try. Then post pictures and tell us how it worked. :D

The difference in length between a 34:18 and a 36:18 tensionerless chain-stay is 6mm, that is a lot of material to file off. If you do, make sure there is enough material in the dropout. You'd be better off using a ratio closer to your chainstay length... like 34:18.

I used both, a dremel and a round medium file. Take a little bit off at a time, check frequently by inserting the wheel to make sure the slots are parrallel.

I posted this 2 years ago - unfortunately the pictures are missing due to issues at MTBR (http://forums.mtbr.com/showthread.php?t=2005). However, it only gives you +/- 2.5mm of ajustability, enough to take care of chain wear.

Cheers,

Tom
