Xenith Pro, Race and Race Femme frames come out of
the same molds as our Xenith SL, Team and Elite series bikes. So you
know you’re getting superbly tuned cornering geometry and Euro-style fit
geometry.
High modulus Dyad Ultra
carbon fiber combined with tri-oval shaped top and down tubes—with our
Size Specific Tubing diameters—means you get incredible ride and amazing
out-of-the-saddle sprinting and climbing performance, no matter what
size frame you ride. Factor in details like asymmetrical chainstays,
forged one-piece dropouts (with replaceable derailleur hanger), and a
full carbon hollow crown fork with stainless axle interfaces and carbon
dropouts, and you’ll see these are bikes that can cut corners with the
best handlers around—but don’t shortcut any of the details that matter.

Features
Features /Benefits
Born from the same molds as our SL and Team, sharing many of the same design features,
constructed with our lightweight-but-durable Dyad Ultra lay-up.
The Xenith’s Tri-Oval SST differential tubing diameters (larger diameters on larger frames,
smaller diameters on smaller frames) support big riders without punishing smaller ones.
Designing the fork to incorporate a 1.5” crown race allowed us to produce a full-hollow
fork, from steerer tube through crown and down to the dropouts: it’s not just lighter,
it’s stronger!
Our seatstays run full length from dropout to seat tube increasing lateral stiffness while
offering greater vertical compliance than standard larger diameter monostays.
Our forged one-piece dropouts, with replaceable derailleur hanger, offer greater strength
and reliability than the industry-standard bolted & glued dropouts.
Xenith’s “muscle” shaped chainstays are asymmetrical, with the driveside 10% larger than
the non-driveside, yielding 30% more volume & stiffness to offset drivetrain torque.
The top of the Xenith seat tube is slotted twice on each side to spread clamp torque
around the tube, and seat posts are securely clamped with a lightweight 1-bolt 7075 seat
clamp.
The larger 46mm bore diameter of the PressFit 30 BB system increases ply compaction
yielding a lighter frame with increased frame strength. Other advantages include:
Improved bearing-to-shell interface, greater bearing durability and simple installation.
Mavic’s Aksium Race wheelset features top Mavic technologies at entry level price point.
Straight pull aero spokes, lightweight welded rims, cartridge bearing hubs, all at a sub
1800g package.
Shimano’s 105 compact 50/34 crank with Press Fit 30 and Wheels Mfg adaptors take full
advantage of the oversized BB shell, larger BB30 bearings while keeping a full Shimano
group for better shifting.
The compact chainring concept is revolutionary: a 34T inner chainring offers a 15% lower
gear ratio than traditional 39T double ringe’d road cranks, but the 50T outer loses only 6%
off the top end compared to the 53T traditional outer. You get the hill climbing capability
of a triple, yet less weight than a standard double
Shimano’s 6700 Ultegra drivetrain assures light, precise shifting over all 20 speeds and
offers carbon fiber STI levers.
Tektro forged brake calipers with sure stopping SwissStop pads deliver solid, predictable
braking performance.
Vittoria Zaffiro Pro Slick tires feature a kevlar bead instead of steel wire for reduced
rotational weight.
Selle San Marco’s Ponza Power Arrowhead saddle rides comfortably & efficiently with
classic Italian styling
