Another day, another wheel (and so on).
A customer left me with a rear wheel from a ZIPP 303.
The rim is WO (Welded Rim) spec.
I also have a Dura-Ace 9000 hub on hand,
and the customer wants the hub swapped out—basically a complete wheel rebuild.
It's a rear hub from the radial-lacing era on the freewheel side,
but while the hubs with silver bodies can't be converted to 11-speed,
the black ones came with 11-speed freebody from the start,
so 11-speed conversion isn't the motivation for the rebuild.
It's in excellent condition with barely any sign of use—
apparently it was ridden briefly, performed poorly, and has been in storage ever since.
This shot is from later in the process, with just the hub isolated,
and you can see the freebody is in pristine condition—
barely any bite marks from the sprocket teeth.
The washers sandwiched between the nipples and rim were Sapim's new B model
(→here)(→here).
The old B washers stick to magnets well, so they're easy to recover,
but the new B washers barely attract magnets at all,
so you have to shake the wheel around and fish them out with tweezers through the rim holes—
pretty tedious work.
It's rare with ZIPP's in-house manufactured wheels,
but one of the washers was deformed because
the long axis wasn't properly aligned to the front-back direction of the rim
before spoke tension was applied.
I didn't reuse that one—instead I used a new B from my shop stock.
All built.
FH-9000, 24H, black half-comp, 4-cross lacing
with black aluminum nipples. I'll do the wire lacing later.
The black aluminum nipples are new—not the 14mm Sapim ones from before the rebuild,
but 12mm DT Swiss nipples instead.
