I recently bought a new bicycle for my wife that was built with sew-ups. It's a NOS bike that's
about 15 years old, and I want to keep the hubs but lace them to clinchers so I unlaced the sew-up
rims. Last night I laced the hubs with fresh spokes and Mavic MA-3s. I laced the rear according to
the steps in Jobst Brandt's book, like I always do.
The problem is the elongation of the spoke holes caused by the first build has the spokes going in
the wrong direction.
Following the directions, I have the hub drive-side down. I keep the in-bound (spoke head facing
outside) spokes in the holes as it was originally laced, and the first spoke goes to the higher hole
on the rim, left of the valve stem. I repeat on the opposite side. Then when it comes time to wrap
the hub so that the first spoke pulls away from valve stem hole, I see that the elongation marks on
the hub are opposite from the way the spokes are oriented. In other words I would have to wrap the
hub the opposite direction, so that the first spoke would angle across the imaginary line between
valve stem hole and rim, if I were to match the existing spoke-hole elongation marks.
Make sense?
What to do?
Not good at these sorts of conceptual puzzles,
