The complex Sender CF downhill bike was designed with an integrated, clean and dynamic design concept. The main frame and the rear triangle form a single unit with continuous lines and geomet-rical surfaces from the head tube to the rear dropout. Only hairline seams at the pivots interrupt the lines. Dynamic surfaces and clean-cut edges lend the bicycle a combative appearance. The sophisticated suspension technology is unobtrusively integrated into the frame design so as not to distract from the overall appearance.
