I see the seller is asking $100, if it's rideable, it's not out of line. Good luck!

If you do a lot of trail riding, don't make the change. On the other hand, if you're on asphalt all the time, with fat tires, who needs a spring?

I am looking online for a used or new rigid fork for a lugged steel Trek 930 frame I bought, and as the frame cost me $60, a fork at $50-$80, including shipping, seems expensive. If there is a bike coop near you, maybe you can find one cheap.

If I were on a student budget, I'd save the dough, as you're halfway to a decent starter C&V road bike.

This thread should be on the appraisal thread, but probably too late to move.
