rear wheel drive-side spoke length

ellis said:

Is there a rule of thumb for how much shorter drive side spoke length should
be from non-drive side for a rear wheel? Let's say I have a 36h rim with
270mm spokes for front wheel for standard 3-cross lacing; same rim & hub for
the rear. If the non drive side is 270mm spokes, how long should the drive
side be? TIA.

Look it up on your spoke-length calculator. In general, the RHS spokes
are a couple mm shorter. In practice, it's not enough to matter.

268mm if the rim is not off center frilled and the hub isn't some sort
of wierd close together flange type-

Disagree that it's not enough to matter. 2mm can mean spoke past
nipples or threads showing. Poor show for a competent wheelbuilder.

Really cheap wheels are often built with all spokes the same size, though.
I've even seen cutters designed to cut off the bits of spoke protruding
from the nipple, once the wheel is built.

Or one of those weird frilled hubs... :-)

Every rear wheel I've built for derailleur-esque bikes has had 2mm
shorter spokes ont he right side vs. the left side. It doesn't make a
whole lot of difference, but the wheel is close to correct dish when
you start to put tension on the spokes.

Nope, I built American Classic hubs into Velocity Aerohead OC rims and
the spokes were the same size and almost the same tension on both
sides of hub.
