I have a 930 Singletrack that I believe is a 1996 model. Frame size is 19 1/2". It came with unsuspended forks, but is "suspension corrected". The frames should have the same geometry for the entire 900 series, I would assume.

Here's what it looks like. I thought a lot about getting a normal "non-corrected" fork like they put on older Singletrack models from previous years. Feels like I'm riding a damned chopper sometimes with those long fork blades. I would much be happier with a normal-length fork myself, but that's how Trek built them back then, for whatever reason.
