Abstract
A pedal construction includes an adjustable pedal subassembly having a lower pedal member adjustably supported on an upper pedal member by an adjustment device. The lower pedal member includes a pedal lever and a lever mount including abutting mounting sections forming a fixed joint. The mounting section of the lever mount has a channel with sharp edges and the mounting section of the lever has a ridge interference fit into the channel. The sharp edges shave marginal material from sides of the ridge when the ridge is forced into the channel, but the ridge has depressions adjacent its bottom that receive the shaved marginal material when the ridge is forced into the channel. Fasteners extend through the ridge and channel to hold the assembly together, with the ridge and channel interface forming a primary mechanical structure providing torsional strength to the joint.
