2011 Specialized Roubaix Expert SL3

Ninety nine percent of us don't need the absolute fastest, stiffest race bike. We don't put out over 1000 watts of power in an all-out sprint like Mark Cavendish, we're not going to pull ahead of a world-class group of climbers headed up Alpe d' Huez like Alberto Contador. We're going to go out for a few 1-2 hour rides a week and throw in an occasional century ride or 60-miler, and we're going to ride New England roads with pavement that is cracked and rutted with frost-heave lumps.

The Specialized Roubaix was built for exactly this kind of riding. Well, actually, it was built to win races like Paris-Roubaix, where the race course includes dusty, muddy, rough cobblestones covered with a patina of tractor gear oil with myriad unexpected obstacles placed between the start and finish lines. Luckily, that just so happens to describe a lot of the roadways here in northern New England too!

The Roubaix SL3 is a fantastic frame whose technology was only available on the $7000+ S-Works version of the Roubaix as recently as last year. Carbon is a fantastic material to build a bike frame out of, since it is almost infinitely tunable in terms of compliance - shaping of the tubes, layup of the carbon fabric make it possible to keep significantly stiff lateral and torsional rigidity while adding a substantial amount of vertical compliance, resulting in microsuspension that both smooths out the potholes and dampens the smaller inconsistencies of the roadway.

The thing that makes the SL3 version of the Roubaix so much better than previous versions is the way it is laid up in better sections. SL2 and earlier versions had a separate bottom bracket piece that chainstays and downtube plugged onto, which resulted in extra structural carbon overlapped and bonded together. The SL3 chainstays, bottom bracket, and seattube make up one piece that makes the bike about .25 lbs lighter, and BB30 carbon bottom bracket shell also contribute to a stiffer, lighter weight system. Size specific stays for EVERY frame size mean that there is specific thought going into every size bike, not just the 56cm one like a number of competitors.

THE RIDE
The geometry of the Tarmac is relaxed. This gives it a longer wheelbase than a race bike, which makes it more stable and predictable at speed. It is still a light (16 lbs.), stiff, responsive bike, just more like a sport sedan than an F1 race car. The ride is plush and forgiving, but there is a sort of positive springy feel to the ride that seems to drive you forward with every pedal stroke. The headtube is probably at least as tall as any of its competitors, and with the 4-position stem that comes spec'd on every level Roubaix there is a huge range for fitting you comfortably (or aggressively) on the bike.

Full Shimano Ultegra 6700 drivetrain, Fulcrum Racing 4 wheelset, and FACT carbon seatpost w/ Zertz insert all add to the ride. Specialized's own Avatar saddle is plush, anatomically correct, and comes in three widths to fit any rider's sit bones.

First Ride: 2011 Specialized Tarmac Expert SL3


Specialized has concentrated an awful lot on their road bikes over the last few years. They have poured resources galore into sponsoring not one, but two Pro Tour teams: Saxo Bank and Astana, and new for this season: HTC-Columbia. Their Tarmac carried the reigning champion of the Tour de France to victory last year, and their Roubaix has been ridden by the winner of the race it was named for (Paris-Roubaix) for the last three years running.


Specialized seems to always be evolving their road bikes, and none so much as the Tarmac. For 2011, the SL3 frame has trickled down from the S-Works model to the Pro and Expert, making the Expert a fantastically stiff, light bike weighing in around 16 lbs at less than half the price of the 2010 S-Works version!

THE RIDE
The geometry of the Tarmac is very neutral. It is quick and nimble, yet stable and predictable. It holds a solid line in the middle of a pack, yet feels playful and positively springy dancing up a climb. The carbon layup, creating the downtube, bb and chainstays as one unit, dampens the rough New England roads, but doesn’t adversely effect the responsive road feel. The bike is a race fit, with long top tube. The headtube is long enough when paired with the Pro Set 4-position stem to put you in a fairly upright riding position if desired, but not so long that you can’t slam that stem if you want to ride like the boys in the TdF.

Full Shimano Ultegra 6700 drivetrain, Fulcrum Racing 4 wheelset, and FACT carbon seatpost w/ Zertz insert all add to the ride. One last spec note: Specialized has been producing their own line of saddle for over a decade, generally offering all their saddles in 3 widths and testing bloodflow with their saddle to help keep you safe and comfortable. The Specialized Romin may be the best spec’d saddle on any road bike offered by any bike manufacturer in the world! It is lightweight, attractive, and jam-packed with technology and comfort.

First Ride: 2011 Cannondale CAAD10 3

A quick ten miles on this early spring morning before the rain and snow swept back through New England was all I needed to get a good feel for the new CAAD10 from Cannondale.

Cannondale could have taken the easy route with the tenth generation of their flagship aluminum race frame, shipped the CAAD9 blueprints off to Asia, trimmed a little weight and called it a day, devoting their engineers to working on another carbon bike.

Instead, they devoted resources in time and money to creating a revolutionary aluminum bike, borrowing technology from their Flash mountain bike and Synapse road bike frame designs, coming up with a new 1 1/8 - 1 1/4" headtube standard, and dropping nearly half a pound off the CAAD9 frameset!


THE RIDE
Snappy, peppy, ready to sprint! The CAAD10 retains Cannondale's 25+ year race pedigree. It is as light as most competitor's standard carbon bikes, has similar vertical compliance (this means that the spring potholes don't rattle your fillings like they usually do on an aluminum bike). Gone are the wishbone seatstays of the last few generations of CAAD frames, replaced with SAVE stays that are super rigid laterally, but give you micro-suspension vertically.

The CAAD10 3 has some pretty big shoes to fill. For the past decade its predecessors: the R2000, then R1000, then CAAD8 Optimo, then CAAD9 3 have been the best-selling workhorse race bike in our store - perfect for hill climbs, crit races, anywhere that speed, lightweight and precision handling are called for.


Look around at the next criterium you go to in New England - you'll see more CAADs than any other bike! It is fast, light, stiff, and won't cost you a mortgage payment when some wingnut takes you out in a tight corner.


Shimano Ultegra 6700 drivetrain, FSA SL-K Light carbon BB30 crankset and Mavic Aksium wheelset rounds out a solid package and keeps the weight of the bike to just over 17 lbs!
