i have the 45degree front to back drop outs ..the torque from the drive pulls the hub loose ...any one know how to set up a device to prevent this from happening
i have the opposite front to backYes. I think they are called 'Skewres', in short little off-set eye bolts you put on both sides hub bolts before the hub nuts, and a stay that cups around the end of the frame chainstay like this.
In short very cool cheap little helpers, especially when chain matching with no tensioner.
Your local bike shop should have them.
That bike by the way is a Grubee GT1, it comes with them as well as a hub mounted drive sprocket.
You don't need a device; you need a proper installation. Grease the axle threads before replacing the nuts and tighten them firmly (with a box end wrench or socket, not an adjustable wrench). If you have a quick-release axle, use a steel enclosed cam type QR lever, oil its mechanism with chain lube, and tighten it through 90 degrees of cam clamping.i have the 45degree front to back drop outs ..the torque from the drive pulls the hub loose ...any one know how to set up a device to prevent this from happening.
Here's the deal: When you tighten a nut, you apply a certain amount of torque, and you get a certain amount of tension on the fastener. Friction takes the torque and wastes it, without using it to tension the fastener. The more you can reduce friction, the more tension (clamping) you get for a given torque on your wrench. So if you are savvy, you grease the treads so that a reasonable amount of wrench torque results in a decent amount of clamping. Good bike mechanics all do this.i am not sure i'm following you on the grease issue? what does that have to do with a tight fit?
