Disc Specific Road Wheels Advice
Why 23c tyres on a road rat? Even the pro’s run 25’s most of the time now. You’d not suffer speed wise with 28’s or even 30’s on a road rat.
Anyway. Most narrower MTB rims can run a 25c tyre ok. I’d not chance anything narrower personally. Rims designed for use with 23c tyres usually have an internal width of 13-15mm. Narrow MTB rims are usually 17-19mm internally which can stretch a 23c tyre into an undesirably flat shape.
If it were me, I’d buy some narrow 29er wheels and some fast 28c tyres, and revel in the extra comfort! You could of course just get something like a Mavic Open Pro rim built onto your current (or some new) disc hubs of course…Posted 4 years agoCraigWMember
The Shimano WH-RX05 road disc wheelset looks pretty good.Posted 4 years agoanusMember
So I have a cotic roadrat with 700c wheels with disc hubs. I dont know so much about road bikes therefore need a bit of help with finding a new set of wheels (someone managed to bend mine to f*ck so need new ones).
I am finding it difficult to find some road wheels with disc hubs so thought that 29er mtb wheels would be a good shout? yes/no? Would these fit some skinny 23mm wide road tyres for example?
If not would anyone be able to help suggest a set of disc specific road wheels for around £200
thanks!Posted 4 years agomboySubscriber
Ouch @ the weight of those RX05’s!!! 😕
Merlin had Shimano MT66 29er wheels going cheap last time I checked. Equivalent to SLX level and a lot lighter than those listed above.
EDIT: Well there were much lighter when they were listed at approximately 1800g for the pair… Now they’ve changed the listing (obviously they were fibbing before!), there’s not much in it now!
Get a wheel builder to build you some SLX or XT disc hubs on some Mavic Open Pro’s, should come in under £200 and will probably be sub 1800g which is more like it.Posted 4 years agoscottyroyalMember
23mm tyres will struggle on a MTB rim, 28mm and above will be fine from experience, and as mentioned wont slow you down much at all. I use 32mm slicks on my cross bike for training and commuting and the difference between that and my roadbike is minimal.
Wheel wise I’d go for handbuilts, I’ve got a few sets, xt hubs on open pro rims for general duties, DT240’s on stans alpha for CX racing and nicer days, both have centre lock rotors for quick swaps. Do also use 29er wheels from time to time, wider rim just changes the tyre profile a littlePosted 4 years agoantigeeMember

I have those CrossRide 29ers on my CX bike. I run them with a 28mm tyre (Conti 4 season) which is the narrowest width recommended for them.
Mavic say that the CrossRide rims are 19mm internal width and take 1.5 to 2.3 tyres:
1.5 to 2.3 isn’t that useful when dealing in road tyres specced in mms (especially given the huge variances in what 1.5 actually measures as) but Sheldon’s excellent page on tyre sizing reckons a 19mm rim can safely take 28 to 44mm tyre.
Having run them with 28 I’d say a 25 would probably be okay, but a 23 would definitely be pushing it.Posted 4 years ago
