Building a flat tracker?

A custom wheel shop like RTR Precision Wheel Lacing can help you with the spokes, or you can stumble through the attached file.

Things to think about are whether the width will be correct for the tire you'll use (narrower 19's are available; the 125/250F used a 1.85), and whether the drilling angles of the nipple holes in the rim are close enough to be used.

Here's the formula for spoke length:

Whenever I saw a guy in front of me at a TT with no front brake, I knew just how to pass him. :smirk:

just a follow up.The rear 19in rim will lace up to the front hub,using the rear spokes.You need to drill the front hub to rear spoke size,life is good
