XC wheelset options...
Moderator: Moderator Team
I have a side-by-side comparison currently. My old hardtail has an Acros wheelset (25.6mm inner width) and the new fully has an XRC1200 wheelset (30mm inner width). The very same tire setup: 2.25 Racing Ray SSkin (front) and 2.25 Thunder Burt SSkin (rear). Since I changing the bikes all the time (HT for training, fully for fun and trail riding), based on my experience I would definitely go for the 30mm (even if there'll be a 50-100g weight penalty in some cases). Wider rims work better with wider tires, cornering grip is noticeably better (okay, a fully corners better by default though) and wheels require a sligly less tire pressure.
Too bad the Acros is 15x100/12x142mm and XRC is 15x110/12x148mm, I would definitely try to exchange the wheelsets.

That'll work.
But I would just use 30mm on both. 57.15mm (2.25") is still plenty wide for 30mm internal width rim.
For the context, my road wheels have 25mm internal width with 28mm tires front and rear.
So, 25mm internal width these days sound more like road or gravel rims.
I tested multiple Wolfpack and Kenda 2.2/2.25 tires and they pair well with 30mm internal.

Agreed. I don't understand why 25mm internal is still a thing in XC.Hexsense wrote: ↑Fri Dec 02, 2022 4:32 pmThat'll work.

I like Duke's approach as well: 30.5mm at front and 28mm at rear. The claim is that, a slighly narrower rim can be stroger. An example: Duke SLS4 rims, ~1210g only, 110kg weight limit: https://r2-bike.com/Wheelset-29-XC-DT-S ... pim-CX-Ray

No wonder Those lightbicycle are light... they are 24mm internal , I don't think anyone rides 24mm anymore nowadays.Jasonlelam wrote: ↑Thu Nov 10, 2022 7:36 amSee this feather light wheels. rim XC924 of "Light Bicycle". When laced with DT240EXP through Sapim CX Ray, it hits ~1120g, and if swap to Berd spokes, it goes down to ~950g WOW![]()

I would recommend 26-30mm at the rear depending on your appetite for speed or stability, and 30mm at the front, wouldn't consider anything below.
Just finished those 30mm internal using Berg 280 rims (had a deal on them, but the aforementioned Duke rims would be just equally good, and much better than anything from lightbicycle). Hubs are Extralite Hyperboost 3, spokes are Sapim CX-ray, 28 holes front and back.

LightBicycle 924s
Chinese hubs and Ti spokes
I haven't had a mountain bike in a few years so I am running 2.2s. It's what I remember. Opted away from berd spokes to Ti, mostly as a cost saver. Plus it's on a Ti bike

I would go with r2 bike for Duke in the US. Very reliable, and you don't pay taxes on them.
