Re-posting ot the clyde forum - Clyde - wt range typically 225 - 230. Would like to jump into the 29er world and was looking at the above bikes. I like the looks of the Cannondale 4 but I am concerned about the rock shock fork in terms of stiffness on the trails. Also considering the Cannondale 1 or Cannondale 2 29er (2009) Have heard great things about the Lefty but have never ridden one other than a parking lot ride. What other forks would be suitable for a heavier rider. The Dart felt flexy when coming off of a curb so I am assuming that it would be worse on the trails. Trails around here have lots of loose rocks, silt mud, roots etc. Thanks
