Similar to the full suspension 100 and as described above the new 29er hardtail is definitely lighter for the upcoming season, but they pulled this off with absolutely no reduction with frame stiffness. To the contrary, they have reported they were able to get the head tube area even stiffer than the 2012 model. Also because the race group requested having a smoother ride while staying seated on rough trails, the newest frame has more compliancy than the older models did. To reduce it’s trail induced chatter, they designed what is called roll wrapped compliant seat tubes. This name was married to it because of a manufacturing process. It gets formed similar to a carbon bar and is then bonded into the rest of the main frame. The seat post then doubles vertical compliance for the frame, and have claimed it offers more give than the Cannondale Flash 29er or the Scott Scale 29ers. This redesigned model also has dropouts that can utilize thru-axle or regular quick release rear skewers. The last item on the recent update list is they changed the placement of the rear brake to a post-mount that places the caliper’s forward mounting bolt on the chain stay tube and the rear post mount on the seat stay tube. The Superfly SL 29er bike will make its first debut at the Olympics, where it will get raced on with American Sam Schultz and Emily Batty the Canadian. Complete bike weighs just under 19 pounds.
