SCOTT ADDICT R1

Generally speaking we're pretty skeptical about hyper-light bikes. We've found that many tend towards a harsh ride with skittish personalities. Because the focus with these bikes seems to be more on being the lightest (not the best) bike, the combination of reduced frame material and super lightweight forks gives them a predilection for twisting and "unloading" in the front end while exiting from hard cornering or on particularly lumpy surfaces. The Scott Addict R1 was designed with a full understanding of this design tendency and with a single-minded drive to overcome it Scott’s engineers paid particular attention to the front end of the bike. In fact, their engineers cleverly designed the headtube and the fork as a complimentary system which allows enough compliance to provide a smooth ride, but enough stiffness to prevent fork extension. Their new Integrated Molding Process (IMP) replaces the tube-to-tube miter joint construction unveiled in 2004, and in so doing reduces front end material requirements by 11% while at the same time providing 20% greater torsional stiffness. The end result is the Pro Tour's winningest frameset for 2009, alone speaking to its remarkable handling and riding characteristics.

The Addict R1 weighs in at a head-shaking 790 grams, a direct benefit of Scott's costly investment in an exclusive high-modulus carbon fiber they term HMX-Net. Scott is tight-lipped about what makes HMX so very unique, but they assure us that there are genuine differences (a higher thread count, for one) which results in lower weight without loss of strength. And speaking of carbon, darn near everything on this Columbia-HTC team-issue frame is made of carbon: cable stops, front derailleur hanger, front and rear dropouts, bottom bracket shell and headset races are all carbon. In fact, the only piece of this frameset that is not carbon is the replaceable aluminum rear derailleur hanger.

An important difference between the Addict R1 and its less-costly sibling, the Addict R3, lies in the construction of the bottom bracket. For the team-issue Addict R1 Scott worked jointly with Shimano to design Scott's press-fit PF BB92 full carbon bottom bracket technology. Also known as BB86, the Addict R1 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.

Few pro racing machines have garnered as much buzz, lust, and envy as the Addict R1. Scott claims their Addict framesets are the most desirable in the pro peloton and that's a claim which can probably be easily defended. But Scott's claims about this frame's weight and stiffness are easily defended and, in fact, verified. In March, 2008 the German magazine Tour tested 24 of what they considered the best carbon frames on the market costing between 800 and 4,400 Euros. In the gold-standard STW (strength to weight) test -- which was actually conceived by Tour back in 1995- - the Addict R1 tied for the top place at 114 Nm/degree/Kg.

The Scott Addict R1 comes in 7 sizes (47, 49, 52, 54, 56, 58, 61). It comes standard with a Scott Addict HMX NET Ltd full carbon fiber fork, and a Ritchey WCS semi-integrated headset. It requires the use of a braze-on front derailleur, a 31.6mm seatpost, and a Shimano BB86 or SRAM Road Pressfit bottom bracket, or a Campagnolo bottom bracket paired with a Campagnolo BB86 adapter.
