Another day of wheel building (and so on).
A customer left me a PowerTap rear hub wheel.
I noticed the non-drive side seemed oddly tight, and when I looked closer...
It was a 24-hole semi-comp 4-cross lacing.
I'm going to rebuild it with a carbon rim.
Since I'm also building the front wheel, I have two of them. Carbon WO rims.
With WO rims, there's a sticker that says "align brake shoes below this point."
While I'm at it, I'm overhauling the hub.
This level of work is something I'm comfortable doing.
If the bearings are new or undamaged,
with the right greasing, you can achieve performance better than the original condition,
so bearing replacement isn't always the best solution.
All cleaned up.
I made a specialized tool to cleanly remove the seals on the bearings recessed deep inside,
and I also custom-ground a syringe
to apply grease to that spot.
I've also switched to a different parts cleaner.
Before, I was only dealing with metal, so I could use something more aggressive,
but going forward I need something gentler
that won't damage the unsealed inner seals of the hub.
The hub shell is cleaned up too.
Built.
Same as before the rebuild—semi-comp 4-cross lacing.
The ZTR Alpha 340's tension limit is 100 kgf,
but this carbon rim can handle 130 kgf,
so it builds up much tighter.
Though I still keep the drive side under 130 kgf as well.
The front hub is also PowerTap.
It has no logos or anything on it, so I briefly doubted whether it was really a PowerTap hub,
but it's definitely the same
PowerTap front hub I've built several times before.
Built.
20-hole CX-RAY reverse spoke radial lacing.
