Another day with wheels (and so on).
I've taken in an ENVE rear wheel for a rebuild.
The rebuild is for the rear wheel only—converting from a 40-spoke to a 46-spoke lacing pattern.
Normally for this kind of work, you don't completely disassemble the freewheel side
and just swap out the spokes on the non-freewheel side... but.
Since we're doing 46-spoke Italian lacing with a right-hand drop, it should work,
except the valve hole ends up in the middle of a bundle of four spokes—
the two final crossing spokes and their two counterparts on the opposite side.
What gives?
I figured out the cause.
It was laced as a reverse rim.
It's laced opposite to the standard hole drilling pattern of most rims.
This rim has no drilling offset (probably), so it can be laced as a reverse rim,
but the ENVE manufacturer site shows it laced as a standard rim,
and I can't think of any reason to lace it as reverse.
Here I have two options:
Treat it as a reverse rim and do a left-hand drop 46-spoke Italian lacing without disassembling the freewheel side,
or completely take the wheel apart and do a right-hand drop 46-spoke Italian lacing treating it as a standard rim.
The first option is easier work-wise, but
I decided to take it apart and build it from scratch.
While I was at it, I cleaned the hub and rim too.
↑Right-hand drop.
Done.
