Another day with wheels (and so on).
Continuing from the other day.
I'm replacing the rear hub on the Reflex Rim
with a thru-axle spec version.
The original hub was an FH-M985 32H, fully CX-RAY 6x6 JIS lacing.
With this hub swap, it'll now be compatible with road 11-speed sprockets.
This hub has a disc mount, but
Based on the rim side wear and dirt buildup on the disc mount splines,
it seems it was primarily used with rim brakes.
The rim side shows some wear in the brake zone with a slight warp,
but going forward (unless we enter an era of thru-axle rim brakes)
it'll only be used with disc brakes, so there's no problem.
With clincher rims, the tire air pressure constantly applies outward force on the beads against the bead hooks,
but tubulars don't have that, so even if the brake zone gets somewhat thinner,
there's no risk of bursting.
↑The spokes are indeed on the short side (both sides).
They're just barely not reaching the spoke nipple slot,
but I'll reuse the CX-RAY on the non-freewheel side.
This spoke length isn't bad enough to call it NG,
so it might be that the wheel builder
had a deliberate preference and did it intentionally.
Whether to respect that depends on how I judge the builder's skill, but
The centering is so off that I suspect the spoke length
might have been pretty haphazard too.
The direction it drifted is consistent with age-related wear,
but you wouldn't get this much drift from that alone.
Also, if the wheel was this far off,
the cantilever brake setup wouldn't fit properly
when swapped for a decent replacement wheel.
Removing the spokes from the old hub, cleaning them, and installing them on the new hub...
the process is the same as with the front wheel the other day.
There was one spoke on the freewheel side that needed replacing.
The one at the bottom of the image—it's bent with lateral force applied.
Laced up.
