anyone know if the rennen tensioner will work with a fat chance yo eddy? the hanger is flat on the vertical surface between the dropout and where the deralleur threads in, that seems to be the main issue.

Rennen on 87 FAT CHANCE Wicked

Put one on an 87 FAT CHANCE Wicked about a month ago. I had a little bit of modificiations to make. The derrailler hole bolt would not go in. Off about about 2 mm. I had to put it in the drill press and widen the slot a little. Then fit up good. I have no idea why it did not work. Maybe these old drop-outs were just a little different. No problems with the flat area fitting. Has been working good for me. I think a great product.

I agree, quality product

everything about the Rennen is first class, and the design is solid. I bet it is just a minor difference in some drop outs. If you had about 30 minutes and a rat tail file, you could widen the slot just as I did on the drill press. I would not hesitate to recommend product.

The Rennen has a limited range in axle-derailereur hole distances. My mainstream Taiwan biek (well a Proto bikewith mainstreatm dropouts) was a tad too long. I rode the bike with the driveside axle NOT fully seated in the dropout, hindered by the Rennen. But I had commited to using that bike to regain a SS title, and for that it worked. Took the Rennen off after and sold it. I've heard much prefereble reports on the On-One Otherdoofer which is similar, but different.
The Rennen relies on a proprietary o-ring which is ever so tiny and falls in the tall grass whatever you try when doing on-trail repairs.
Once installed I much say the Rennen is about as good as a SS gets. I did get lucky with chain lengh though.
A friend got an Otherdoofer (highly similar for chainlength issues) and it was hard to get it to work with a chosen gear ratio, either too much slack to take up, or too short a chain. Halflinks are good things to have, if you don't want to use 2nd-choice cog sizes.

thanks fellas

i looked into the dropout / hanger bolt distance by lining up an extra replacable hanger i had lying around next to the fat hanger and it seems to be a few mms off depending on what angle i hold it at. i will probably just file it to fit if need be. now i just need to get it...ordered it 2 thursdays ago and asked george to 2nd day it but still don't have it. anyone have experience with ordering from rennen direct?
