What an unpleasant feeling when I walked into the bike locker. The front wheel and fork were stolen. That $ucks!

I would like to replace it with a non suspension fork for 2 reasons, I only ride on paved surfaces and it's cheaper. Could not find the physical frame spec sizes for my 2010 Trek 7500. I would welcome any suggestions for a rigid fork that does not change the frame/fork geometry of the original setup. I was thinking of a threaded fork (only a thought) because I like the idea of adjusting the height of the bar by loosening 1 bolt. I have that old style handle bar with locking wedge...somewhere. Thanks Much!

what you need to do is find the axle to crown distance of the fork. You have some leeway replacing a suspension fork since the A/C distance changes. "Suspension corrected" rigid forks are fairly easy to find, and it probably isn't too important what the A/C distance is as long as it's within a reasonable range. But knowing the original A/C distance will help you know how far off you are.

Looked and searched at many web sites for that A/C (axle to crown) measurement but have not found it yet. So, if anyone knows what that A/C is please post a reply. Thanks

is that a 29'er? Do you know what the travel is?

on edit: hybrid, 700c, looks like it has 35mm travel.

I would probably ask the local Trek dealer what they would do, that's probably something that they do occasionally

Followed your suggestion and called my local Trek dealer. To maintain the proper geometry a "suspension corrected ridgid fork" can be used to replace the OEM fork. I may try searching for a used 700c suspension fork. Thanks unterhausen for you kind help.
