It all started with aluminum tubing and it remains among the best materials for creating rock-solid mountain bike designs that allow riders to get off the beaten path. Trademark Cannondale details, including the PowerPyramid downtube and optimized tubing, make for a lightweight, rugged frame.
HEAD TUBE DESIGN
We push our engineers to constantly reduce weight and improve ride performance. On the CO2 SL, this is done in part with an externally butted head tube that gives ultra-precise steering and reduces weight.
BUTTED TUBING
Cannondale's butted tubing optimizes wall thickness and tube diameter at frame junctions for unparalleled performance and the tailored ride qualities hardtail riders seek.
