Another day of wheel building (and so on).
Continuing from yesterday.
Building a rear wheel for disc brakes with a HED Belgium rim.
The hub is Paul's rear hub for single-speed fixed gear,
and when I looked into whether it had reverse dishing, it turned out it technically did,
but the actual measurement showed only about 0.2mm of left-right difference,
so it's not severe enough to force asymmetric lacing—
in fact, you shouldn't do it.
I can treat it as a hub with no dishing.
Paul's hubs of this type are normally made in bolt-down specs for frames that use nut-type hubs,
and what bothers me is that directly under the frame's dropout sits not the hub axle itself
but the bolt's threaded portion.
However, this hub uses a thru-axle design, so there's no problem.
From that previous rear wheel, I was able to transplant 2 straight spokes and 2 reversed spokes from the 6-spoke side.
Out of 32 spokes, I got 28 into productive use.
Since the rear wheel I'm building now is 24H,
the remaining 20 are new spokes, but
When you cut spokes, the plain section length on the rim side varies.
For example, CX-RAY's standard stocking lengths at Japanese wholesalers come in 2mm increments of even millimeters,
and it looks like you could cut down about 8mm,
but I limit myself to 6mm cuts.
It's a combination that wouldn't occur in my wheel builds,
but if you pair an 8mm-cut CX-RAY with a 16mm-long nipple,
the inner edge of the nipple will interfere with the start of the butted section on the spoke before you finish building the wheel.
When building a wheel with CX-RAY 280mm, you can use the 280mm as-is,
but you might also use spokes cut from 282mm, 284mm, or 286mm.
However, I never mix different original lengths in a single wheel.
The spokes for this build are DT Competition, which come in 1mm increments,
and Competition can be cut up to 30mm,
so for example, 270mm could range from using 270mm straight
to cutting 300mm down by 30mm (I didn't use 290mm as the example
because there's no original 320mm Competition size).
We keep four different silver Competition sizes in stock,
and use them to cover roughly 303mm down to 240mm.
I said Competition can be cut 30mm,
but actually even at the widest gap it's only about 20mm.
When I checked, I found that the 4 Competition spokes transplanted from the Turquoise rear hub
were all originally one of those lengths,
so I cut the remaining 20 from that same length.
This means all 24 spokes have uniform plain section length on the rim side.
Built.
24H all-Competition radial lacing, JIS standard, no crossed section.
