A customer brought in a Neutron Ultra for me to work on.


It's basically brand new — only ridden here to the shop since purchase.
There was a slight wobble and some play in the rear hub,
but the centering on both wheels was spot-on.
You get quirks like this sometimes.

The rear wheel is built radial on the non-drive side, but

↑it has extremely high/low flanges,
(especially the small flange on the non-drive side is pretty extreme.
If you think about where the spoke head sits
compared to where a normal hub's flange hole would be,
you can really see how tiny it is)

↑drive side

↑non-drive side
With left/right different-length spokes,
the spokes are quite well tensioned
for a radial build on the non-drive side.


The rear rim says "asymmetric," but

↑actually having a truly asymmetric rim profile like this
is only done on Hyperon.
The Neutron, the previous model Neurcion, and
the budget version Proton all

have rim shapes that are basically symmetrical left-to-right.
The rim holes are offset to the left (not a political statement, mind you),
so it's technically an "offset rim"
but calling it an "asymmetric rim" doesn't quite feel right.

If you mean "the spoke trajectories on each side are asymmetric,"
then that's already the case once you have dish.


↑the rim holes are offset left, and there's also some variance in hole positioning left to right,
so the hole corresponding to the non-drive side flange
sits right at the edge.
Because of that, there's a reinforcement wall built into the rim interior.
