Corsa :: 7003 Aluminum Road Race Bicycle

Pro bike racers are paid to race, train, suffer and win, but what they're REALLY paid to do is represent their sponsors' marketing interests. Now, there's nothing wrong with this - every cycling fan realizes this on some level and knows that sponsorship is the lifeblood of bicycle racing, from the Pro Tour on down to the amateur ranks. Bicycle companies pay vast sums of money for the privilege of having elite athletes ride their products and, in turn, these pros are duty-bound (and contractually obliged) to effusively proclaim the superiority of their sponsor's bicycles, regardless of what they might think in private. Gone are the days where pro riders used to secretly, or not-so-secretly, have custom bikes made for them and re-badged with their official sponsors' logos. Sponsorship contracts have become so large and important to the bottom lines of teams that this practice is now economically impossible.

With this in mind, the Gaulzetti Corsa is designed to be the bike pro riders would ride if they had a choice of frames. It's a race machine in the purest sense; built for pure function, and designed with a keen understanding of the rigors encountered by racers, from early season training miles in horrible winter conditions, to the longest, most grueling summer road races. In short, if the job is training and racing, the Corsa is the ideal tool for that job.

The decision to use aluminum to create this racing machine was a simple one: Aluminum provides the optimum characteristics necessary in a race frame. Its low density means that tubes can be made to the large diameters required for a stiff, lively bicycle while avoiding an undue weight penalty. When built correctly, from premium materials, aluminum bicycles ride well, handle predictably and last indefinitely. 

The Corsa is built with a custom drawn blend of butted 7003 aluminum tubes from Dedacciai. The main tubes and chainstays are all very large in diameter to maximize front end and drivetrain stiffness while the seat stays are relatively thin, to reduce weight and helps smooth out the ride quality. Unlike most other aluminum bicycle designs, the tubes on the Corsa are neither radically shaped nor are they extensively relieved. These two processes can create bicycles that are light and stiff, but can also unnecessarily degrade the ride quality of the bicycle and produce the "tin can" feeling often associated with aluminum. In fact, the Corsa's ride characteristics are more similar to fine steel bicycles. There’s a smoothness and mellowness to the ride quality of the Corsa that is decidedly unlike other aluminum bicycles on the market. In addition to the surprisingly smooth ride, the first thing one notices when first riding a Corsa is the stiffness; not only the exceptional drivetrain rigidity, but also in the front end of bicycle which does not move or shimmy when pulling hard on the bars. The result of this front-end stiffness is that the Corsa behaves responsively and predictably during hard, out-of-saddle efforts such as sprinting and climbing. It also results in a bike with supremely confident high speed cornering characteristics. There’s no vagueness in handling, no question that the bicycle will steer where you point it at high speeds.

The Corsa uses an integrated seatmast with a few topper options, but can also be built to accept a 30.9 seatpost if the ISP is not your preference. The BB is a machined Press Fit 30 shell while the head tube is 44mm that fits the Chris King Inset 7 headset, which we supply as standard equipment in your choice of King's colors. The Corsa accepts a 34.9mm clamp-on variety front derailleur. The standard fork is Enve Composites' Tapered Road fork in either 1.25" or 1.5" versions (size dependent).
