Prototype 1100g Fulcrum Carbon 29er Wheels Spotted on Merida Team Bikes

With the tape visible around the edge of the rim it’s pretty clear they are tubs. Dugast (for one) will take a tread from an existing tyre and glue it to one of their casings. My guess is that’s what we’ve got here.

1100g isn’t too difficult, I built some Edge tubulars, CXRays and DT hubs a couple of years back which came in around that mark.

Definitely looks like a casing with tread glued to it… Well, at least from this picture that’s what it looks like. It’d be cool to see some close-up shots! Still really light wheels, though.

Clint, it’s not unusual to have Dugast casings with any brand threads.
When Friskies first appeared with 650c wheels, in 2004, he was running Dugast with Ritchey threads.
Also, Paulissen and others were seen with Schwalbe threads on camouflaged Dugast.
In fact, you can order those tubs with your favourite thread.

Somewhat off topic…

1. Is that an xx1 crank with a 1×10?
2. Short cage RD?

(hard to tell)

Thanks!
