Would 25mm rims be ok for a 2nd set of wheels for light duties on a Trance X. The stock wheels are very heavy and the 2.4/2.5 tyres give very little mud clearance for the local claggy conditions. Thinking of using 2.3 max tyres and feel 30 rims may give a poor tyre profile. I weigh 10 stone so am fairly light on wheels so could get away with a light build, maybe DT Swiss?. This is my first trail bike after moving from a 26er so a little vague on what is common practice.
Yeah, 25mm are fine for most stuff, everything moved to 30mm standard for trail/enduro stuff, but for 2.2/2.3 tyres, 25mm is more than enough.
If you want light wheels then there's loads of makes to look at, the usual suspects all do them, Hunt, DT Swiss, etc, what is your budget and are you only buying new, or looking at secondhand market as well?
A mate the same size with a Trance has just done exactly this. Can’t remember the brand of wheels, but he’s really happy knocking out 100km xc / gravel rides with them, then swapping back for the gnar.
You won't get a "poor tyre profile" running 30mm and 2.3's, and there's next-to-no weight saving between 25mm and 30mm rims.
Aim for sub 1800g as only 10st.
Ok ta, budget around £500 current stock wheels are 2450g
Christ, you'll could save 1kg easily with new wheels and tyres, for 500 new i'd be looking at seeing if you can get a set of DT Swiss XR 1700s, or older M1700 or x1700 with the 25mm internal width, would save you a lot of weight and always well built and ready to ride wheels.
Shh, don’t tell anyone, but 25mm rims are actually good for everything, although if you say it out loud you will be ridiculed for even considering riding on anything less than 30mm.
Mum’s the word 😉
I don’t think anyone heard so it’s all ok your secret is safe with me👍
I just went with 30mm internal rims (well, 29mm to be precise) on my new bike after years of riding 25mm id.
Can't really tell the difference.
28mm is the magic number.

If you'd gone from 30mm to 25mm you wouldn't be here to tell the story!

Interested in links too as I need a 148*12 in 12sp HG.
Well over on the other wheel thread Hunts were panned by one user, supported by another, and previous threads went the same way as I found some from back in 2018 singing Hunts praises and slating them in equal measure. DT Swiss seem to be everyone's 'friendly budget' faves i.e. under £600-700, but tbh, I have really struggled to find anyone with stock, of what I was after - the 1700s mentioned above, plus I'm confused by the endless list of options. My Bizango has boost front and rear, and an annoying (it turns out) 141 QR rear. Apparently 148x12 with QR hub adapters is the way forward for me but I'm still confused by all of the different options and part names for rims, hubs etc to know what is what. I do get 6 bolt and the correct option for cassette compatibility etc though.
@reluctantwrinkly, DT Swiss XR391 is a great 25mm inner width rim for the lighter rider. I'm 88kg without kit and have a set on Pro4s on my gravel bike, but I specced them with an eye on future dual use on a trail MTB. Not sure if that's the same rim DT Swiss put on the XR700 wheelset mentioned above.
I prefer a wider rim for sidewall support and tyre volume. Before 30mm rims I ran 26mm and they were fine. Its about incremental improvement.
2.3s on a 30mm rim will be fine but will provide a little less volume. Beyond a certain point, thinner tyres on a wide rim become less deep, a bit more like a radial car tyre but you'll probably be ok.
At 92kg I was, although I was running maxxis DD and and insert, and a bit more pressure than I liked for grip.
Cheap heavy wheels seems to be a giant thing and a budget of 500 will get you something rather better easily.
My LBS just had some DT MTB wheels turn up, including some XM 1700's, so they're definately coming in.
Any DT Boost rear can be adapted to 141 Q/R with end caps.
You could get a custom build - for 25mm internal rims then DT Swiss XM421 are a really good trail rim.
Get them built onto the hubs of your choice - on a £500 budget maybe Hope Pro4 / DT350 / Bitex - with double butted spokes.
I’ve had multiple sets of XM481 (the 30mm internal version of the 421) and a set of XM421s and they’ve taken all the abuse I’ve thrown at them so far.
