SCOTT CR1 SL

Flashback to 2004, when Scott unveiled the CR1, stunning the bike industry and ushering in a new era of carbon bike manufacturing technology. It also forever changed the meaning of a "lightweight" bike frame. The all new Scott CR1 SL pays homage to its namesake by its combination of seemingly contradictory qualities: Supreme comfort and high performance.

The 2010 CR1 SL uses the same IMP (Integrated Molding Process) as the Addict R1 and R3. Specifically, Scott molds the front triangle as one piece instead of using the revolutionary tube-to-tube miter joint construction it unveiled in 2004. It also uses the same HMX-Net carbon fiber that Scott reserves for their full-blown, competition-crushing Addict race bikes. In most every detail, the CR1 SL is identical to the Addict series and it is 11% lighter and 20% stiffer than its previous incarnations: but there are two significant design characteristics inherent in all of the CR1 series that set them apart from the Addicts, specifically, a more relaxed geometry and a focus on comfort.

The purpose of the CR1 is to provide you with the same high-performance design and technology features of the Addict R1 and R3, but to do so without forcing you to contort yourself into an aggressive, pro-style position. So, the geometry of the CR1 series differs from the Addict series in two key areas: the headtube height of the CR1 SL is 1.5 centimeters taller than that of the Addict bikes, and the CR1's toptube length is .5 centimeters shorter. What's the point of this? A taller headtube will a) fit a larger percentage of the population, and b) provide a less aggressive position on the bike. Since the headtube height is taller, you don't have to arch down so far to reach your handlebars. Effectively, to the degree the headtube height is raised there is a corresponding degree to which the toptube is shortened, and hence giving you a less aggressive and more upright and relaxed position.

Beyond the benefits of relaxed geometry, the CR1 SL has a technological upside absent from the Addicts: Scott's Shock Damping System (SDS). SDS technology minimizes fatigue-inducing high frequency vibrations and provides vertical compliance through a combination unique tube shaping and the strategic orientation of carbon fibers. In fact, the CR1 provides such a degree of vertical conformity that up to .6mm of compliance is measurable at the axles. This is achieved through Scott's S-Bend tube shaping technology which essentially "tunes" the tubes of the rear triangle and the fork blades so they vertically displace as dictated by the requirements of the rider's weight and the road conditions. But note that the shape of a carbon tube alone is not enough to provide compliance; compliance is a result of a combination of tube shape and the manner in which the tube's layers of carbon fibers are oriented. Adjusting for the appropriate amount of lateral and torsional stresses is achieved through enabling the various layers of carbon material to deform at those places on the frame where the greatest comfort will result with the least amount of power transfer loss. So, Scott orientates each ply of carbon fabric at strategic locations on the frameset so the frame's uniquely shaped tubes provide just the right amount of flexibility (for comfort) and stiffness (for performance). And, according to Scott, as compared to the Addict series the CR1 SL shows absolutely zero loss of lateral stiffness.

Raceworthy? Keep your eyes peeled during the 2010 season, especially during the spring classics' campaign. You'll see the CR1 SL on the rough-and-tumble pavé where its unadulterated performance and shock absorbing qualities will bring a hint of forgiveness to the riders of the world's winningest pro cycling team, Team Columbia-HTC. The CR1 SL weighs a feathery 860 grams due to a reason other than its use of Scott's top-shelf HMX-Net carbon. In addition it uses Scott's press-fit PF BB86 full carbon bottom bracket technology. Also known as BB86, the CR1 SL bottom bracket corresponds to Shimano's proprietary crank spindle and bearings' specifications. The tolerances of BB86 are so precise that Shimano's external bearings press into the BB shell with no need for threads. This design saves 30 grams over traditional, aluminum threaded shell designs and, at the same time, provides additional bottom bracket stiffness. It should be noted that while BB86 is designed specifically for Shimano, we offer adapters that allow for the use of Campagnolo's external bearing design as well as the SRAM GXP external BB.

The Scott CR1 SL frameset comes in 7 sizes ranging between XXS and XXL (50.5, 51.5, 53, 54.5, 56, 57.5, 59.5). It comes standard with a Scott CR1 HMF NET full carbon fiber fork and a Ritchey Pro integrated headset. It requires the use of a 31.6mm seatpost, a braze-on front derailleur, and a Shimano BB86 bottom bracket, or a Campagnolo or SRAM bottom bracket paired with a Campagnolo or SRAM-specific BB86 adapter.
