Read on for more info on the 2010 Flatline...In 2009 we got a chance to test one of the Rocky Mountain Flatline Pro's, and were pleased with the overall build and feel of the bike, but disappointed with the weight. In 2009 The Flatline Pro tipped the scales at 46 lbs 3 ounces, which made it overweight. Rocky Mountain used the Maxxis team riders, Luke Strobel, Cameron Cole, and Sabrina Jonnier to redesign the Flatline as a race bike for 2010. Now at 39 lbs and dialed in for the race season Rocky Mountain is ready to release the 2010 Flatline Pro and 2010 Flatline World Cup.



This new design will not put an end to the previous Flatline design as it will still be available in 2010 as Rockys freeride bike, and labeled the Flatline FR. The Flatline World Cup and Pro feature a refined geometry with input from the Maxxis Rocky Team, integrated headsets, and a specific (non-adjustable) geometry. Also the head tube angle is also effected by the fork length (axle to crown) and with the Flatline's lower stack height you get more adjustment for a steeper or slacker head tube over other bikes, by simply raising or lowering the stanchions. This simple 15mm adjustment will adjust the head tube 1 degree slacker, or steeper.

The Rocky Mountain Flatline launch took place in Pemberton where the trails are confined by tree's and branches, littered with rocks and rough lines, and were slightly damp. The Flatline, despite its 785mm wide bars and slightly steeper head angle felt stable when descending, and not twitchy or unpredictable at high speeds. The new Flatline is 2 inches shorter front to center than the previous frame design, so if you were not planted behind the bike when descending it felt easy to get over the bars in a uncomfortable fashion, this could have been a result of the low stack height. However when you were planted behind the bike descending the front tire tracked fine, while the suspension did all the work to keep you upright.

I got a chance to take the Flatline up into the Whistler Bike Park area for a couple laps on the jump intensive trails, and was impressed with how it rode up there. The Flatlines LC2R suspension design felt great under pre-load and landing of jumps, and still stayed plenty active when it was being piloted over extremely rugged or brake rutted sections.

The Flatline lineup for Rocky Mountain is going to be a contender on the race circuit in the 2010 race season for sure, so if your in the market for a new race bike, or just looking to try something different take a look at the all new Flatline.
