Done it! Roller-Cam

[MikeD]

It's pretty, but I don't think it's ever going to work terribly well - there's not much pulling in the right direction going on, and doesn't the cam hit the seat tube at some point? A togglecam would work better

As long as i keep the blocks close to the rim then it doesn't hit the seat tube.

What's a togglecam is it like a web cam but for bikes

fixed. locking the wheel up nicely
