Tubeless rims

[HammerHed]

I am looking at getting a new MTB wheel set for my S-Works Epic frame and want to buy a tubeless rimmed wheel so I don't have to use Stan's tape or whatever.

 

I have Fulcrum 3 rims on my road bike and these are "tubeless rims", meaning they have no holes for spokes nipples on the inside if the rim, so you  can basically just add a tubeless valve and tyre and slime and you are away with a tubeless system (No tape required).

 

So my question is what MTB rims are there that offer this  or am I hopelessly misinformed. I see that the DT Swiss rima all require a tubeless conversion with rim tape etc.

 

Why? I thought UST meant tubeless in the style of a motor car.

The best value for money tubeless wheel set is the Shimano XT wheelset.

Or you can look at doing a custom build?

The type of rim you describe requires a spoke and nipple system that doesn't require access from the spoke bed side of the rim. These are proprietary systems which come with problems of their own. See the Mavic threads here.

 

DT's rim offers access from that side but has a special rim tape to cover it. It's tight fitting and I think, airtight or at least airtight after an initial application of goo.

 

I don't see why you should have a problem with the airtight tape system. It offers you the advantage of standard spokes and rims.

The only true tubeless rim on the market is the Mavic XM 819, other than that you can buy factory built wheelsets ie XTR

Thanks for all the feedback guys, I bought the Fulcrum Red Metal 3 wheels  on the weekend.

 

These are UST rims, the rims have no holes for the spokes on the inside and you don't need the tape strip, just slime and tubeless tyres.

 

I put Mountain Kings 2.2 for the rear wheel and Maxxis Monorail for the front, both UST tyres.

 

It was quite effortless to do. Ok I have got a compressor so that helped to get them to seal first time.

 

I am looking forward to riding them, my bike is almost ready, just got to fix the rear disc mounting bracket, it is about 8mm too low for my Avid Ultimate 160mm discs so the disc touches the caliper. Dammed if I can find a bracket anywhere in Joburg.
