Comfort. The Alter Cycle Reflex frame has patented structural features that have significant benefits for every rider.

The frame has no moving parts that require maintenance; the top tube and down tube work together in a subtle flexing movement that produces a smoother ride through a unique type of frame flex Alter engineers refer to as linear flex. To provide linear flex, the down tube flexes allowing the wheelbase to stretch and retract in response to bumps and dips in the ride surface. Because the flex is in extension, the response produces no annoying bouncing or bobbing effect as the frame contracts. The action takes the edge off bumps, keeps tires on the ground more consistently and noticeably improves handling and control.
