Another day of wheel work (details omitted).
Continuing from yesterday, I'm rebuilding the rear wheel.
The rim is the same as the front wheel.
Hub from the stock wheelset - 28H
Black #14 plain 3-cross JIS spoke lacing.
The rims before and after rebuilding - both are low-profile,
so I was able to stack them together.
This rear wheel is for a Cannondale AI offset frame,
so the rim needs to be offset 6mm toward the non-driveside.
Therefore, the spacing between the left end and the centergage probe should be 12mm.
When I measured before disassembling, the original state was 11mm.
↑Non-driveside
↑Driveside
↑Non-driveside
↑Driveside
The spokes tend to be even shorter than the front wheel.
If the spoke length was chosen so that the relationship between spoke and nipple end surface was equal left and right without AI offset correction,
and then tightened more on the non-driveside to offset for AI,
the non-driveside spokes should appear longer visually,
but actually it's the opposite. I honestly don't get it.
It's built.
28H all-black CX Sprint 3-cross JIS lacing without cross-lacing.
I judged that cross-lacing wasn't necessary.
It would be fine to do it, but if I did, it would be full cross-lacing on both sides.
It's been a while since I built a rear wheel with equal-diameter, equal-number spokes on both sides.
I could have used all Compte spokes instead of CX Sprint for all spokes,
but CX Sprint has a lower spoke weight ratio,
so I chose it with an eye toward keeping the wheel itself light.
I've set it up for AI offset compatibility.
Both before and after the rebuild are 3-cross JIS,
and the marks of driveside and non-driveside spokes on the hub flanges
followed the original pattern on both sides.
↑Non-driveside
↑Driveside
↑Non-driveside
↑Driveside
Both sides have the nipple ends flush with the rim tape.
↑Measured weight of front wheel rim before and after rebuild
↑Measured weight of rear wheel rim before and after rebuild
Accounting for the weight difference between brass and aluminum nipples,
the total comes to about 100g.
I'll explain in a separate post why the fact that the Crest MK4 rim is an offset rim is something I find less than ideal.
