I would have a non-boost wheelset related question. I have an old Canyon carbon XC hardtail with Niner rigid fork, 15x100mm, frame is an old 12x142mm one and I'm planning to use it as a hillclimb machine (sub-8 kgs already with rigid fork) but the current wheelset I have, that's more than 5 years old with 20k+ kms (Acros 29 XC carbon) and both hubs have issues already & also no warranty anymore.
Since I have a CX/gravel bike as well and I would need a spare & light wheelset to that bike as well, came to my mind, what if I bought a CX/gravel wheelset that I could use also in my old hillclimb XC machine. :)
For example: https://www.dtswiss.com/en/wheels/wheel ... 400-spline

my only problem, is it possible to convert the 12x100mm to 15x100mm? Somehow it's not clear this to me, also not found any info on this yet. Thanks!
Yes they can be converted,but i am afraid the DT conversion end cap is very difficult to buy under current market condition.

thanks for the info. Still thinking about what would be the best option. :) Actually, I have 9mm/15mm DT end caps, mtb and road versions as well. I'll ask my friends who has DT road wheels and try to test these end caps whether could be used or not.

I'm looking at "superlight" 27.5 rims currently.

Has anyone seen any rims worth considering recently?

These have caught my eye (posted on page 4 of this thread):

MSC Koncept Carbon Di2 - 6955g

Shoutout to EIE Carbon. I had them build me an i35 wheelset for a Giant Trance and 2.6" tires. It's not an ultralight build, but I think the shallow profile and chunky 3.5mm bead wall will contribute to durability.

Bitex BX211 6B XD 54 POE 28H hubs
Pillar 1420 spokes w/ aluminum nipples
A29C35D18 "SL" rims in UD Satin w/ black gloss decals

Cost was under $750 shipped. Calculated weight was 1513g. Actual weight was 1495g. They weighed the non-rim parts separately for me; working backwards, the rim weights were exactly as estimated.

On the build: flipped on a coin on CL vs. 6B. DT 350 was tempting and 40g lighter, but I can't stand the noise with a 54T ratchet. CX-Ray was less tempting; I've built based on Pillar and Mac and whatever functional differences exist are too subtle for me to tell. Brass nipples weren't worth the weight for a wheelset I expect never to true.

From payment to delivery was about 3 weeks, but this included two builds. The first build was based on the A29C30D18 rim and came out a bit heavy (1460g). They offered to rebuild on the same rim or a different one at no cost, so I switched to the wider version that was a better match for the tires. The delivery was well-packed, undamaged, and included extra spokes and valve stem decals.

I've had a A29C29D25 build with the non-Boost MTR12 Bitex hub on my Scalpel for the last four or five years. Zero problems with it. I've only put a hundred miles on this set, but I'm expecting more of the same. The difference in weight and sidewall support relative to the stock 1750g i30 Giant wheels has been surprisingly noticeable.
