One of five American women that took on the might that is European
cyclocross at the 2005 'Cross
World's in St. Wendel, Germany this January, Velo Bella's Sarah
Kerlin took a very respectable top 20 placing and finished as the second-best
American rider behind veteran Ann Knapp.
The bike she rides on tackles similarly formidable opposition, going
up against the Giants and Bianchis of the world. Somewhat of a cult
figure in the Cali MTB scene, Paul Sadoff is the man behind Kerlin's
Rock Lobster 'cross machine, and has been building custom frames for
over 20 years - starting with his sister back in 1978!
While Sadoff has branched out of the family tree since then, he continues
to keep his Santa Cruz, CA, operation ostensibly a one-man band: "If
the frame has my signature on it, you can be sure that I built it,"
he writes on his
website. "I don't have a production line in my shop and most likely
never will."
Despite being a non-profit cycling team based out of Monterey, CA,
the Bella babes have a number of 'patrons', one of which is Rock Lobster
for their cyclocross bikes. Kerlin's custom frame is made from Easton
Scandium hydroformed tubes, a very popular choice in 'cross circles
(is that an oxymoron?), with a True Temper/AlphaQ cyclocross-specific
full carbon fork up front.
"It is based on my road bike, with obvious cross specific changes,"
says Kerlin to Cyclingnews. "It has more clearance for bigger
tires, and while having a somewhat compact design, a lot of room is
left to shoulder the bike. The angles are fairly similar to the road
bike as well."
One of the benefits of having a bike based largely on her road steed,
says Kerlin, is that it behaves like a road steed. "A little force into
the pedals gives instant acceleration. No loss of power here, and the
handling is superb. I can launch off a drop, or fly down a steep rutted
chute with no chatter or noodling whatsoever. It is a very comfortable
ride, I don't experience any vibration, thanks to the Easton Scandium
tubing."
Kerlin mentions that after plenty of road racing and criterium experience
the last few years, her riding style is now more attuned to the road
rather than a mountain bike: "I spend lots of riding time with my hands
on the hoods, it gives a more upright position and shifts my weight
to the rear," she says. "No chicken levers, I am almost never up on
top of the bars."
However, the Masters
30-34 national champion adds that the hoods on her 'cross bike sit
a little higher than her road bike - a little extra leverage for steep
ups - and after a bit of to-ing and fro-ing, she's gone with a one centimetre
shorter stem, most likely for that extra bit of manoeuvrability. "And
of course smaller chainrings - same cogs though!" she quips.
The tubular wheels are key to performance, Kerlin remarks about her
custom built wheels. Components are a real hodgepodge; a mix of Shimano
Ultegra and Dura-Ace 9-speed, TruVativ, Thomson and SRAM are seen on
Kerlin's Rock Lobster in various quantities, with Fi'zi:k's Aliante
doing the honours at the rear - literally. "The best component upgrade
I made this year was the [Crank Brothers] Eggbeater pedals. The technology
here is head and shoulders above any other pedal on the market," Kerlin
says.
