Can CX wheels be used as 29ers?
Most disc CX bikes will have 135mm spacing. Running Stans Crest Hope Hoops 29ers here with no issue on my Kinesis Pro6. Gives quite a wide tyre profile which may or may not be your thing. I’m not bothered either way.
I’ll probably swap for Iron Cross rims soon, but only because I’ll use the Crests on a new 29er, and not because I’m desperate to change.
I’d say that proper CX rims would be okay for MTB to a point, as long as you aren’t looking at anything too narrow and hoping to run wide tyres.Posted 4 years agojonbaMember
My commuter (pompetamine) has superstarcomponents 29er wheels on.
My CX bike is running Hope Pro 2 Evos and lighter rims.
The only things to look for is that CX wheels may be built up light rather than strong. Also the rims may be narrow so that CX tyres fit well so running wide mtb tyres may be an issue. I had the opposite problem in that the mtb rims were too wide to get narrow slick on so I’m unning a 32mm not a 25mm.Posted 4 years ago

They seem fine, but I probably can’t go much narrower. I think.
(Mavic recommend a minimum tyre width of 1.5 – which I think translates to 28mm. Sheldon certainly reckons 28 is safe minimum on a 19c rim)Posted 4 years ago
According to the CTC the rule of thumb is:
“The ideal relationship between tyre and rim section is about 1.8 to 1, but any tyre from 1.4 to 2.2 times should fit”
So using that a 622-19 rim should take between 26.6 to 41.8 (which roughly tallies with Sheldon’s table).
Anyway, it seems to run just fine 😀Posted 4 years ago
