XXX, very light, full carbon fiber, looks amazing. Has a nice glossy finish with some subtle carbon texture still visible underneath.  This model design is several years out of production, circa 2008.

PLEASE NOTE: The clamp is for round 7x7 rails only, not oval 7x9 rails. The single-bolt clamp design of this post requires that it be carefully tightened to spec with a torque wrench, and may even require the use of carbon friction paste, to avoid rotation when the saddle is under load.

Length = 400mm

Diameter = 30.8mm

20mm setback.

Weight = about 185 grams
