Cannondales 2009 Rize Carbon 2 Mountain Bike
The London Cycle Show, held in the United Kingdom in the city of London last month, had a number of the big cycle manufacturers present with their new 2009 models. Cannondale presented their 2009 Rize Carbon 2 (see photo), which is painted in Cannondale's Berserker Green gloss colour. Cannondale also paints the Rize Carbon 2 in the colour of Lightning White gloss, and in this colour configuration, the Schwalbe brand tires come with a bright red side wall, which looks awesome. Cannondale has built some interesting technology into a number of their 2009 Mountain Bikes and we'll try and detail some of this here.
The Rize Carbon 2 is only surpassed by Cannondale's Rize Carbon 1 in terms of their highest technology full-suspension mountain bikes, but the Rize Carbon 2 shares a significant amount of the Rize 1's technology at a lower price. The Rize Carbon 2's frame has been designed to merge carbon composite material construction with aluminium machined components. The load bearing parts of the frame are machined in aluminium, whereas the cross members and other light elements are in carbon composite. Cannondale has developed a metalforming technology that integrates the BB30 shell, lower pivot, and double-butted seat tube into a single 3-D component. The total frame weight including the front fork/shock, mountings and rear shock is 4.736 kg (10.4 lbs), and just the frame itself weighs 2.115 kg (4.65 lbs).
Cannondale has a very unique front fork/shock component whereby the wheel mounts on a single offset fork arm, rather that the conventional two fork arms found on most bicycles. They give this a brand name of 'Lefty Headshok'. With only one fork arm, it allows for a reduction in fork/shock weight, because only one larger shock and one fork arm is used at the front. Specifically, the Rize Carbon 2 uses Cannondale's Lefty Max Carbon 130 RLC Headshok, which is their top of the line mountain bike fork and weighs just 1.36 kg (2.99 lbs) including all suspension parts. It can be locked out by pushing a blue button on the top of the fork housing. The rear shock is a Fox Float RP 23.
For gear changes, Cannondale's Rize Carbon 2 uses Shimano XT series for the front derailleur and Shimano's XTR series for the rear derailleur and the shifters. Braking front and rear is by Avid Elixir CR hydraulic disc, and the brake levers are also Avid Elixir CR. The crank is a Cannondale SI Carbon (22/32/44), and the rear cassette is by SRAM, a PG-980, 11-32, with an SRAM PC-971 chain.
The handlebars on the Cannondale Rize Carbon 2 are FSA XC-282 AOS, and the stem is a HeadShok SI. For the dynamic wheelset, Cannondale has specified Mavic CrossMax ST rims, with Mavic CrossMax ST hubs and spokes. The tires are Schwalbe Nobby Nic UST's (26 x 2.25"). For seating, there is a Fi'zi:k Gobi XM saddle and the seat post is an FSA SL-K Carbon.
