    surly 1x1 wheel pulling loose on the brake side?

    Just built up a Surly 1x1 frame with the parts off of my old bike. I've got the Surly tensioners on both sides. Under hard braking on rough surfaces the wheel will pull loose on the brake side, sliding back and binding the brake. (running discs) It pulls the oposite way that the tensioner holds. I've got the scewer pretty tight. How do I stop it? Had to stop 4 times in a 17 mile ride and re-center the wheel the other day.

    What QR are you using ? Often times the QR does not have enough clamping force and an upgrade is neccesary . I have had excellent results with Shimano XT QR's . Good luck .

    When you use the rear brake it tries to move the wheel backwards in the track ends.

    I don't think a QR is up to the job of locating your wheel with a disk on a 1x1. It works ok with V-brakes.

    This problem is why some manufacturers are moving their disk mounts forward and down, so that the reaction to the braking forces is upwards rather than along the axis of the track ends.

    Get rid of the chaintug on the brakeside.
    It doesn't help you, and it's smooth surface only reduces friction.
    And use a good QR, like Shimano (XT).
    When that doesn't solve your problem, you'll need a bolt on rear axle.

    i have a 1x1 with xt quick release and no tensioner with no real problems. i have to make sure i tighten it really well or it will come loose when i mash hard enough on the pedals. i do plan on getting at least one tuggnut to prevent it from happening ever.
