ive just got a pair of crossmax sl, i was asuming that i could use them with normal tyers and tubes but ive just had a quick google and there seems to be mixed opinions about this.
Q1 are normal tyers ok to use?
Q2 the valve of a normal tube wont fit through the rim, would it be really stupid to ream the hole a little to take the larger valve.
Q3 should i wait and get the rest of the kit to go tubeless.

a bit anoying as i was hopeing to get this bike back up and running without spending much more.

Just going down this road myself 8)

I am going tubeless but non UST - a bit of reading on the Stans forum suggests this is ok, one of the examples used being a crossmax (tick) and kenda klimax's (tick) so I am hoping it will work well :D

I got Mavic UST valves (nicely made and look neat 8) might sound sad :oops: :lol: but they have no visible thread, have nice collars that protect the rim with an o ring and come with a presta adaptor for initial bead seating / inflation), a bottle of Stans and the injection syringe - both cheap off the net, post free 8)

Pics are in my build thread, can send you suppliers if you want ?

You can wait and see how I go on this weekend, I can see it getting messy and looking like a porn movie gone wrong ... :lol:

WD :D

As far as I know you can use normal tyres with those wheels, I have used tyres & tubes with my Crossland's

Normal valve? do you mean schrader (car type)? or presta? or will both not fit?

You could ream the hole out, it will weaken the rim a tiny bit, being a lightweight rim you would have to be very careful to not compromise them (IMHO)

If you have a set of usable wheels I'd wait and then go full tubeless if you have any nagging doubts

i ment car type valve, if i went tubless id like the option of using tubes, though im not sure of the tubless system yet. guess theres only one way to find out.

Yes :D just put them together with the blasted frame - look nice ... 8) I can't say I've seen many Ti frames with all silver wheels (normally black) but it looks pretty cool :D

WD :D

I wanted black to ! But having seen the silver with the frame, I think it turned out right ;-)

I think silver rims / spokes look better in later life to :D

Then just use Presta tubes - they'll fit.

I don’t think I would drill them out – even a little :-(

If I look at the inside of the rim, the middle channel is very narrow and only very slightly wider then the rim hole.

If the rim hole was enlarged I think it would permanently compromise the sealing area for the UST valve making it a one way modification …
