my brother is borrowing my Cinelli Pro Best Of' to do the Etape next year. The bike currently has Bullet Ultra 50's fitted. He wants some lighter climbing wheels and is attracted by the merits of tubeless technology.

Firstly, is tubeless the way to go for riding in the mountains (ie climbing and subsequent descending)? If so, which direction should he be heading?

The options as far as I can see (without spending an absolute fortune) are:-

Fulcrum Zero 2-way
Shamal 2-way
Stans 340's on either Chris King or DT 240S with Sapim CX Ray spokes

Whatever he goes for, it must be campy compatible, not stupidly expensive and appreciably lighter than the slightly portly Bullet Ultras.

Cheers

You could always build up the 340s to Alchemy hubs instead of Kings. This will increase the overall flange spacing just a tad which will increase lateral rigidity. Additionally, it would shave a bit of weight from the overall build which is always nice.

thanks for the advice ref. Alchemy hubs... i'll have a look at those.

what about the American Classic Tubeless wheelset? It seems crazy-light for the cash as an 'off the shelf' option (sub 1200g for sub £800)?

cheers

perfect!

Tune Mig/Mag Hubs with Stans 340 Alphas and an upgrade to Sapim CX Ray spokes...

next question... at 6ft tall and circa 80kgs, what spoke setup should he go for? 20/24 or 24/28?

also,,, what is this carbon winding lark all about (on the rear wheel). does it make a difference? (or one worth paying Euro 45 -70 for?)

cheers

The new Velocity A23 has a tubeless compatible bead. Another good, though heavier, option. 8)

Highly recommend the Alpha 340's with Alchemy hubs. Those are the best wheels I've ever had! 20/28 with Sapim CX-ray.... Plenty stiff, very light, and descends fantastic (contribute that to the amazing hubs just as much as the tubeless).

I've always thought it is a good idea to overbuild on the 340. It isn't the stiffest rim out there, and with that said, I would go 24/28 or 24/32.

Does anyone know the weight of the Fulcrums or the Shamals? Would you say that they would be heavier or lighter than the 340's?
I write the weightweenies blog, hope you like it :)

@atakaoka I'm sorry, I meant the rim weight, not the wheelset weight
