Another wheel day (and so on).
I took in a wheel rebuild job on an EDGE 1-25 rim.
The reason for the rebuild was to upgrade the hub from Tni 10-speed to 11-speed.
Originally it was fully CX-RAY with a 4-cross laced pattern and soldered connections.
Yeah, that's right. I was the one who built this wheel originally.
Even back when I first built this (several years ago), I already had the concept of asymmetric lacing in mind,
and I was using it for both my personal bikes and for bikes I was selling.
So why didn't I use a 46-cross pattern on this 24-hole rim?
Because I wanted to keep it as light as possible.
Basically, for wheels the priority is "rigidity over lightness" unless the rim is excessively heavy,
but since there's basically no other rim this light around, I prioritized the lightness I could achieve.
Even though it's from the generation after the 195g catalog spec, in the 215g era,
this rim happened to fall on the lighter end.
In its current state (at ENVE), this rim is spec'd at 250g,
and my actual measurement also comes in just over 250g.
Given that, compared to the ENVE 1-45 which weighs just under 300g in actual measurement,
the outer circumference weight up to the 25mm rim height section isn't that different,
and since the 1-45 has nipples and spokes positioned more toward the inner circumference,
and shorter spokes result in better rigidity, I think
that for current ENVE standards, even if we're talking purely climbing use,
the 1-45 might actually be the better choice.
It's also more resistant to buckeling damage too (like hitting a pothole or curb edge and cracking the rim).
But with this much weight reduction, the 1-25 definitely suits climbing better.
↑The soldering looks pretty rough, huh. I put too much solder on it. Yeah, embarrassing.
Rebuilt.
Still doing the 4-cross with soldered connections, can't help myself.
It came out to 576g in actual weight,
but if the hub had been a bit heavier and I'd done 46-cross instead,
we might have ended up in the 600g range. That's a big difference.
With a 207g rim, I can build a front wheel under 424g,
so we could even make a wheelset under 1kg front and rear.
↑The soldering—someone more skilled than me might laugh at it,
but looking back over several years, I'd say the finish has gotten considerably better.
Per the customer's request, they asked me to "remove the cement tape and transition to adhesive tape,"
which is the work I mentioned in my earlier post as being tedious.
I managed to get it cleaned up enough to transition to tape.
The 207g measurement I mentioned earlier was taken in this state.
