Will I be able to set up these wheels and run them tubeless?

[ED209]

My road bike was set up tubeless from new and I think it’s great for avoiding punctures.

I have bought a second hand tt bike with some mavic wheels and I would like to run them tubeless if possible. The maximum tyre size the frame will take is 23 I think.

So it’s it possible? Advice would be appreciated thanks.

Pretty sure almost any rim can be run tubeless - with the right rim tape, valve and tubeless ready tyres.

One thing I've seen on older rims being converted, they didn't necessarily meet the tolerances for a predictable and assured first time seal of the bead. I'd have thought mavic carbon rims, just by their nature, will be 'fine' (with 'fine' meaning everything from right first time through to a week or two of topping up and reinflating as everything gets airtight.

Also which tyres would be recommended? I don’t think my bikes frame will take bigger than 23c

Can you make it work - possibly / probably with enough fiddling. Should you, probably not

The rims are designed to retain the bead with a hook and a tube, they don't need to have the bead sealing on the base of the rim bed. Potentially you'd need multiple layers of rim tape/gaffa to get enough diameter in the bottom for a proper seal. Read up on 'ghetto tubeless'. Additionally, you're running 23's which need plenty of pressure so will be harder to get to seal, both on the rim and less likely that the sealant will work on an actual puncture.
Tubeless really comes into its own with larger tyres that run less pressure (and for that matter off road where you probably want to run very low pressures without pinch flats).

Personally I don't get the fetish about tubeless and road punctures. It takes 5-10 mins to swap a tube if you're half compenent, and if you don't run worn out tyres/ride around things and not in the crap right by the kerb, punctures are pretty rare. I'd guess I get 1/year? But if you're determined, the smart move would be to get a tubeless compatible rim. They ARE shaped differently..

ETA - Just noticed the tyres tho - I would get rid, they're horrible (IMO of course) and puncture magnets. conti Gp5000s would be my suggestion.

dont bother, pointless on a road bike.

put 4000s on not 5000s, better tyre i think

Cosmic carbon pros with exiliath rims tubeless you ask??

Yes is the answer.

I have the GP5000 TLs on my road bike.

With these and my previous tubeless bike, I've not had a puncture in 12000 miles....touch wood.

I don’t think those wheels are the same as mine though, there seems to be about a million types of mavic wheels and I get confused as to what is what.

Are they a tubeless ready version or just normal wheels you have converted to tubeless? Sorry but I am pretty clueless

They were tubeless ready from Mavic, which iirc they call UST, mine were from 2017 which I finally put tubeless tyres on last year.

By way of an update I have decided to godown the gp 5000 road but with inner tubes.
