Andy sold me a few fork crowns here a little while back, and now I'm ready to get busy building me a fork for my road bike.

Existing fork is a Reynolds Ozuo Pro w/43mm offset. I think it's about 270 370mm, axle to crown (or something close).

Plan is to build a fork with as much tire clearance as possible. The Reynolds will clear 25's, but the rear end looks capable of at least 30's, so that is my goal...if not bigger.

I'm thinking something in the range of 42mm offset, and as long as possible. Slowing the steering is not a problem. Rim brakes, Dura-Ace 11 speed calipers. How wide a tire will fit between the brake shoes on these calipers?

I'll dry fit and check clearance, etc, before brazing the legs into the crown, but you guys are so dang smart, I'd like to solicit suggestions before I begin.

Please share any suggestions. Also, suggestions on a simple brazing fixture.
