We take the term “pro-level” very seriously. This
isn’t just a marketing term for us. We take pro-level to mean it’s what
pros demand and deserve.
Xenith SL is the definition of
pro-level. And we prove it, under the legs of the Jamis/Sutter Home
men’s squad and Colavita/Forno D’Asolo women’s team, two teams at the
top of USA Cycling’s 2011 NRC calendar week after week. For 2012, we
modified every Xenith mold to be compatible with FSA’s new PF30 BB
system, offering all the advantages of the original BB30 system –
lighter, stiffer, stronger – with press-in cups that makes later bearing
replacement a cinch. Our advanced NearNet molding process, unique to
the SL, is still the benchmark for the ultimate in compaction, yielding
incredible stiffness, precise road feel and amazing power transfer that
extends from fork tips to rear dropouts. Stand on the Shimano Dura-Ace
crank and the SL responds. Right now.

Features /Benefits
What’s NearNet? A revolutionary molding technology that produces the cleanest,
most consistent, most accurate monocoque with the highest compaction qualities
we’ve yet popped from a Xenith mold. Both frame & fork are NearNet molded on the SL.
Our ultra-high modulus Omniad lay-up has been FEA optimized, machine tested,
then field tested on the road and in races to insure the perfect fiber lay-up, eliminating
unnecessary layers of material, assuring the lightest, strongest, best performing Xenith SL
yet!!
Every SL is made with an impact resist resin binder that enhances structural integrity
and increases impact toughness.
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.
Our “conventional”, non-integrated seat tube/seat post design simplifies test rides as well
as travel and enhances re-sell value.
Our seatstays run full length from dropout to seat tube increasing lateral stiffness while
offering greater vertical compliance than standard larger diameter monostays.
The 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.
Our forged one-piece dropouts, with replaceable derailleur hanger, offer greater strength
and reliability than the industry-standard bolted & glued dropouts.
Our front derailleur clamp spreads shifting forces around the tube instead of localizing
them at one point as would the more standard rivet-on front derailleur perch.
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. The key difference with PressFit
30 is how the bearings are fitted into the frame. Bearings are housed in nylon cups that
are pressed into the frame’s bottom bracket shell. Like BB30, PressFit 30 uses the same
bearing that is designed for a 30mm spindle cranksets. Advantages of PressFit 30:
Improved bearing-to-shell interface, greater bearing durability and simple installation
Shimano’s Dura Ace 53/39T crankset with PressFit 30 ceramic bearings and Wheels Mfg
adaptors take full advantage of the oversized BB shell, larger BB30 bearings while
keeping a full Shimano group for better shifting.
Shimano’s Dura Ace C35 tubular features proprietary in-house high modulus 35mm
carbon rim construction, double butted bladed spokes, angular contact bearings with a
upgraded digital cone-bearing adjustment and oversized 12mm axle.
