"The Look KG486 is a
spot-on road racing bike that won't beat you up or let you down."
A solid winner
Designed with plenty of input from French star Laurent Jalabert, the Look
KG486 is a spot-on road racing bike that won't beat you up or let you down, says
Chris Henry.

The Look KG486 is by now a proven frame in the professional peloton. The
frame was unveiled at the Vuelta at the end of 2002 and appeared under Crédit
Agricole and Kelme team leaders Christophe Moreau and Oscar Sevilla (and later
Alejandro Valverde) in 2003 before becoming standard team issue for both teams
in 2004. The bike has been an important project for Look's new star consultant,
Laurent Jalabert, who since retiring from racing at the end of 2002 has devoted
more of his time and input to the design processes at Look. Jalabert won more
than 100 races on Look bikes throughout his career and knows a thing or two
about what a pro needs in a high performance frame.

The KG486, the first bike for which Jalabert worked through the entire design
process, is a distinctive blend of aero styling and solid construction in a one
piece carbon frame. The bike gives a very solid ride, but doesn't thrash the
body from being too stiff, and the KG486 offers a frame design that highlights
both form and function. As has become common on high-end carbon frames, the
tubes are designed to provide stiffness and flex in the right places, meaning
the seat tube retains an aero shape (complete with a cut-out around the rear
wheel), while the top tube twists to flare laterally as it continues from seat
tube to head tube.
The seat cluster is an impressive mass of molded carbon, likely the source of
some of the frame's 'extra' grams, but also a functional example of Look's
workmanship and design. At around 1500g the KG486 is far from the lightest frame
in the peloton, but Look has never pursued weight at all costs, preferring to
tune the whole package, and going for reliability, perhaps after watching some
of its competitors' frames turn out to be less than durable. The frame also
incorporates what Look calls its 'double curve' on the rear seat stays, designed
to once again combine lateral stiffness with vertical vibration dampening.
Look's 'Progressive Sloping Evolusize' means the amount of top tube slope on
the KG486 varies depending on frame size. The smallest frame, a 49cm, has up to
65mm of slope, whereas a 59cm frame has no slope at all. The goal is to provide
the same handling and ride quality throughout the entire size range. Look didn't
just jump on the sloping top tube bandwagon for fashion's sake, rather the
frames are designed with geometry in mind and built accordingly.
The full-tilt carbon components, including ITM Millennium Ultra-Light
handlebars, Look's Ergopost 2 seat post and Carbostem, as well as the company's
own beefy carbon crankset, provide nice complements to the monocoque frame. The
ITM bars have a slightly deeper drop than I would have preferred but otherwise
had a classic, comfortable shape. I used my own saddle for the test, a Fi'zi:k
Arione, as well as the Campagnolo Eurus clinchers for most of the riding. The
Eurus are strong, light, and dependable over all types of terrain, worthy of
training or racing on a frame like the KG486.

Out on the open roads, the Look rolls smoothly - and quickly. The Campy
Record provides perfect shifting and the Eurus wheels complement the bike's
design with a stiff but forgiving ride. Even on moderate sections of pavé, the
bike absorbs vibrations quite well and feels sturdy. Having owned a carbon frame
(lugged, not one piece) that failed, it's nice to at least feel confident that
Look's construction will last.

I might, however, prefer a little less carbon in the total package.
Specifically, I would feel somewhat more comfortable using more traditional
materials for the seat post and handlebars. This is strictly a personal
preference, but I don't believe every part of the bike needs to be
carbon. Oh, did I mention the water bottle cage is carbon?
Actually, the carbon cage is an accessory that Look got right. The C-shaped
cage holds bottles snugly over all road surfaces, cobbles included, and this
nothing to sneeze at. Look's carbon model may be light, but personally I'm not
the least bit concerned with the weight of a bottle cage. All I want is for my
drinks not to go flying or rattle every time I hit a rough patch of pavement,
something that seems hard for too many cage manufacturers to master.

All in all, the Look KG486 was a joy to ride. The frame's weight was the only
notable issue, and for me it was not a deal-breaker. From the first ride, the
bike felt comfortable and exactly as I expected a bike to feel. That is, the
adjustment period was as short as any. The front-end handling was responsive
without being jittery, while the one piece carbon frame soaked up enough
vibration without feeling spongy. The bike was just as comfortable after four
hours as it was after two.
Fitted with the superb Campagnolo Record group, the KG486 offers virtually
everything a top of the line race bike should. Weight-watchers could always make
substitutions of some parts to shave grams, but for me the bike's ride was nice
enough to look beyond the weight, which only seems extra by comparison.
Pro: Sturdy design, great handling and ride quality
Con: On the heavy side for high-end carbon
