Chain tensioners that fit vertical drop outs? I've looked everwhere, ebay, craigslist, uinversal cycles, nashbar... no one has them. I know they exist though because i saw a set on a conversion. This was befre i needed them so i didnt ask where to find a set.
Thanks

i've never used one, but hearsay votes for the surly singleator. you can't use it if you're building a fixed gear though.

edit: nevermind. we're not talking about the same thing.

edit #2: what the hell are you talking about? chain tensioners push the wheel. with a vertical dropout there's nowhere for it to go.

? Semi-vert? ITT... my head hurts.

Maybe you mean horizontal dropouts, i.e. not track ends? If so, a Surly Tugnutt works beautifully on my conversion, particularly in conjunction with the little holes in my 1010 dropouts. I bet just about any tensioner will work if you are prepared to mod it and./ or your dropouts slightly.

yo meng, what are you building and why haven't you informed me of it.... if its the basso then you can use the surly one's cuz the fit perfectly on the notch on the back of the drop outs.

edit: or did u finally get a mountain bike frame for a polo bike? damnit i need to finish mine.... so yea hit me up later im trying to build some crap before the ride tomorrow

Not sure if this is what you mean, but I have a similar problem. There is enough of a gap tolerance in my vertical drops to allow the wheel to shift on the drive side. This was aggrivated by a poorly installed axle by the local shop (just a little too much axle sticking out on the QR so the wheel would tighten but not quite enough to keep it locked in place). Worked fine when geared, but now on SS/Fix the offroad mashfest pulls the wheel forward and detensions the chain.

Had some SKS tensioners from a track frame, but the wouldn't workout. Not sure if there is anything else out there that would do the trick.

You running QR on that setup? Having proper tracknuts/bolt on axle has made a huge difference in grip for me, anyway.

no im not running QR... they are for semi vertical dropouts the kind on road bikes, I know they exist because i have seen more than one pair on bikes. Thanks for the help though... send me some pics of your conversion, and when i get my rear wheel shipped ill have some of mine up.

BMX "star" chain tensioners..just file off the back part.

PS. QRs are fine on fixed gear bikes.
