Are there any frame builders that use the XLR8R component set?

Cinelli?

I'm confused. Isn't XLR8R a bike? It has readily available mainstream components. So, every frame builder builds bikes with XLR8R components, right?

It is a set of carbon fiber tubes, made by Columbus, from which to construct a frame.

If it is the name of a bike, the builder presumably licensed the trademark from Columbus, and that particular frame probably uses the Columbus bits.

They do, indeed, make one - from their Web site ...

XLR8R5

COLUMBUS Carbon XLR8R Max

Full Carbon frame made with wrapped oriented ellipse shaped tube set, Columbus XLR8R MAX (Double Oval Concept) for an excellent stiffness/weight ratio.

[EDIT] Actually, they appear to make two - the Estrada is also one of these.

Orbea made one as well

Cable stops are riveted. 46-62cm, in 1cm increments, for the standard frame, and 48-62cm, in 1cm increments, for the sloping top tube version.

Thanks - I now understand the error of my ways.

XLR8R is offered in both C and Al (which I must have forgotten). It is the Kit Mecano that is C only, and was what I really meant to ask about in the OP.
