Can I install these:

on a road frame with horizontal dropouts?

If so, how? You have a pic?

Thanks.

Probably. I wouldn't guarantee that they'll work with every frame, but I just checked a couple of older road bike frames in my besement and I'm pretty sure they would work with both of them.

The rear wheel's axle goes through one of the big holes and the moveable part of the chain tensioner rests against the back of the dropout. Tightening the bolt pulls and holds the axle back in the dropout.

So the tensioner affixes to the outside of the dropout. Thanks, good description. Does a person need to use them on both dropouts, or is one sufficient?

What, exactly, are you trying to do?

Bolt-on rear axles can be a pain to set up because the axle likes to "walk" forward as you tighten the axle bolt. That's even more important on singlespeed and hub gear bikes because, when you install the rear wheel, you also have to set the chain tension.

Sometimes the BMX guys just put a tensioner on the drive side to save weight or something. I like having them on both sides because it's so much handier to dial the rear wheel exactly into the middle of the dropouts.

:D. Nothing crazy, really. I bought one set of tensioners for the purpose you described. I have a fixed conversion and a ss conversion, and I was just trying to determine if I could just use one per bike, rather than buy another pair. Thanks for the info, it's all I needed.
