The OEM fork for the frame i bought had 65mm of travel. When converting to a rigid fork, how does that translate to proper, or closest offset?
Chalo said:There's no single answer for that. It's "whatever offset gives you the desired amount of trail". Trail is a function of head angle, wheel diameter, and fork offset.
The amount of trail you're looking for varies by riding style, typical speed, and amount of load carried on the front wheel. For a very fast bike, you want more trail. For a bike that carries lots of weight on the front, you want less trail. But you can't go much wrong shooting for about 2 inches of trail.
What kind of bike are you retrofitting with a new fork?
With MTB suspension forks, you don't really get to choose from among different fork offset values. They're all going to be right around 44mm. It isn't always right for the job, but it's what you get. If you can find a rigid fork with a little more offset, you might like the handling better.
The shorter the fork is from axle to crown, the less steering trail you'll have with the same fork offset.
