A SRAM GIGA-X-Pipe bottom bracket. Giga-X-Pipe was Truvativ's (later bought by SRAM in 2004) approach, and is an evolution of the ISIS Drive bottom bracket, but with a longer spindle and the bearings outside the bottom bracket shell. The spindle is permanently pressed into the right crank.
SRAM is an acronym comprising the names of its founders. [2] The company produces a range of cycling components, including Grip Shift, and separate gravel, road, and mountain drivetrains from 7 to 13 speed. SRAM developed the Eagle line of mountain bike specific drivetrain components intended to improve shifting performance. [3]
Eccentric bottom bracket on a Burley tandem bicycle held in place with two set screws. The term is also used to refer to the device often used on tandem bicycles with timing chains, single-speed bicycles with a rear disc brake or an internal-geared hub, or any bicycle with vertical dropouts and no derailleur, to allow slight repositioning, fore and aft, of a bottom bracket to properly tension ...
Electronic front derailleur (Shimano Di2) An electronic gear-shifting system is a method of changing gears on a bicycle, which enables riders to shift with electronic switches instead of using conventional control levers and mechanical cables.
Elastomeric bearing pads, to serve as bridge beam supports heads. An elastomeric bridge bearing , also known as a pot bearing or elastomeric bearing , is a commonly used modern bridge bearing . The term encompasses several different types of bearings including bearing pads, bridge bearings, laminated elastomeric bearings, and seismic isolators ...
Bearing pressure is a particular case of contact mechanics often occurring in cases where a convex surface (male cylinder or sphere) contacts a concave surface (female cylinder or sphere: bore or hemispherical cup). Excessive contact pressure can lead to a typical bearing failure such as a plastic deformation similar to peening.
Flat thrust bearings, the most common spiral groove bearings, are so named because one consists of a flat surface that opposes the grooved surface. Variations in this type of bearing come from the nature of the spiral surface and the type of fluid flow. The following is a list of the different types of flat thrust bearings: With transverse flow
The lower half of the main bearings are typically held in place by 'bearing caps' which are secured to the engine block using bolts. The basic arrangement is for each bearing cap to have two bolts, but some engines may have four or six bolts per bearing cap (often referred to as "four-bolt mains" or "six-bolt mains" engines).
