rear wheel slipping in dropout

[ocd]

i have a track wheel, standard bolt on mounted in a 120mm road frame. i'm getting a bit of slipping in the dropout. the bolts a tight, but still slipping on the drive side. any ideas? i'm considering roughing up the dropout w a file for a bit more grab. thanks in advance

Correct assumption—if the nuts are tight, rear wheels mostly slip because the dropout material is too hard and/or too slick. Roughening the dropout faces a bit should help, so will removing the chrome if there is any. Start with the inside dropout faces, that may be all you need. I'm assuming your wheel is held on by real track nuts—the kind where the nut turns independent of the washer.

drive-side chain tensioner?

On a road frame? I would assume that the OP has forward facing dropouts.

Of course, like so very often, I could be wrong.

Campy Track Nuts with separate washer work great for this.

I've used them on fwd-facing road frames as well as track drops. On a road frame you use the rear curve of the dropout for leverage. Push/pull is same-same, regardless.

I know the Surly tugnuts work with traditional forward facing dropouts.
