Abstract: A seat attachment device is provided that uses a single bolt to secure the seat rails to the seat attachment device and the seat attachment device to a post.

Abstract: A system and method for connecting dissimilar materials is described. In one embodiment, the system may be used to produce a break apart frame that includes a first section and a second part which is disengagably connected to the first part by fastening members. The first part includes a head tube, a top tube and a down tube. The second section includes a bottom bracket, a seat tube, a pair of seat stays and a pair of chain stays. A connection tube extends from the bottom bracket so as to be disengagably connected to the down tube. An end tube is connected to the seat tube and disengagably connected to the seat tube.

Abstract: A barend mounted twist shifter provides for ergonomic shifting and eventual brake actuation. The barend, which commonly provides an ergonomic hold on position for a bike rider's hands at the peripheral handlebar ends provides for an attaching location for the inventive twist shifter. Consequently, a bike rider may operate the bike's derailleur without taking his hands from the barends. A brake actuator may be combined with the twist shifter. The shifter's spool around which the shifter cable coils, may be positioned in the assembly adjacent the barend's tip. Its minimum diameter is substantially independent from the barend's outside diameter and may be reduced such that the actuation torque on the gripdrum may be lowered as well. The gripdrum and spool may be combined with a ratchet mechanism that may be easily integrated in the shifter's housing adjacent the barend's tip. A thumb perch serves as a release for down shifting.

Abstract: A bicycle pedal is described that is more easy to engage and disengage and that has a hollowed out central section to prevent debris build-up. The bicycle pedal has a pedal body rotatably supported by a pedal shaft wherein the pedal body has planar pedal surfaces and a pivotable clamp member generally perpendicular to the surfaces of the pedal wherein the clamp member comprises a central contact surface and a clamp located at a lengthwise end of the clamp member. The clamp member extends out from a surface plane of the pedal for clamping to a cleat and the clamp also has a slideable guided surface acting in an arc-like way to perform a jaw-like movement. The bicycle pedal also has an urging device disposed against the clamp member such that it contacts a central contact surface of the clamp member and urges the clamp member inwards.

Abstract: A handlebar mounted shifter system and method are provided in which the overall diameter of the shifter is reduced by providing, among other features, an integrated clamp and spring assembly. The shifter housing has a small diameter so that a rider may place his index finger comfortably on top of the housing so that the distance between the rider's hand and the brake actuator is reduced. In addition, the handlebar mounted shifter system may support and guide the shifting cable so that the shifter cable does not flex undesirably.
