Abstract: A bicycle assembly can include a main frame having a bottom bracket shell to receive a bottom bracket. The bottom bracket shell can be made of carbon fiber with one or more metal rings to serve as bearing surfaces within the bottom bracket shell. The metal rings may also be split metal rings with a gap between two spaced apart ends.

Abstract: A bicycle assembly can include a front or rear suspension system with a shock absorber. A front suspension system can be a suspension fork. A rear suspension system can include a rear shock absorber. The shock can have a shock body and a pressurized main air chamber within the shock body to act as an air spring. The shock can also have a valve configured to receive a pump for adding air to the main air chamber. A secondary air chamber and a control member can be used to reduce the pressure within the main air chamber by venting the secondary air chamber to the atmosphere.

Abstract: A bicycle that including front and rear wheels and a frameset supported by the wheels. The frameset including a main frame with a seat tube having a width, a fork that couples the main frame to the front wheel, and a seatstay assembly. The seatstay assembly including first and second seatstays positioned on opposing sides of the rear wheel and on opposing sides of the seat tube. A front end of the first seatstay is spaced from a front end of the second seatstay by a distance greater that the width of the seat tube. The frameset also including a suspension mount that is detachably secured to the front end of the first seatstay and a suspension member that is pivotally coupled to the suspension mount.

Abstract: A bicycle including a front wheel, a rear wheel, and a frameset supported by the front wheel and the rear wheel. The rear wheel includes a first end cap and a second end cap, and each end cap has an aligned hole extending through the end cap. The rear wheel includes an axle that is positioned in the holes in the end caps and that defines an axial direction. The frameset includes a first dropout and a second dropout, each including an opening. The axle is positioned in the opening of each dropout. Each drop out has a lip that defines a slot aligned with and larger than the openings. Each of the lips is dimensioned to receive a corresponding end cap of the rear wheel. The lip of the first dropout has an axial length less than the lip of the second dropout.
