just bought a 1999 Curcuit, nice, stiff, fast ride. Aluminum fork is okay, it’s definitely stiff and adds some chatter to the bars but for lower miles it isnt too bad. Comfortable frame but wants to go fast. It handled nicely and looked like you could maybe get 32s in the frame? I just measured a Denti and could be confusing the measurement though. I was very, very surprised at how nicely it rode. I immediately started thinking about drivetrain replacement and a carbon fork. It’s a 1” threaded aluminum fork as of now. The Schwinn branding is cool and you get some intrigued looks by people, especially if you’re keeping up/going past them.

What’s the top tube measurement?

Good eye, I didn’t notice that! I picked at the defect with my fingernail and it came right off - it was a bit of slag or debris caught under the paint. Here’s what it’s like now:

The rear dropout is 130mm.

Thanks!
