Compact chainrings have been the dominant standard for mountain bike cranks since the mid nineties. In the context of road cycling , compact drivetrain typically refers to double cranksets with a smaller (usually 110 mm (4.3 in)) bolt circle diameter than the standard 130 mm (5.1 in) or Campagnolo's 135 mm (5.3 in).
Crankset or chainset: composed of cranks and at least one chainring; Cup: receives ball bearings which roll along its inner surface; integrated on most conventional hubs or can be pressed into older bottom bracket shells. See also Cone; Cyclocomputer: an electronic accessory that measures and displays instantaneous and cumulative speed and ...
This page lists notable bicycle brands and manufacturing companies past and present. For bicycle parts, see List of bicycle part manufacturing companies.. Many bicycle brands do not manufacture their own product, but rather import and re-brand bikes manufactured by others (e.g., Nishiki), sometimes designing the bike, specifying the equipment, and providing quality control.
Pisgah: Geometry identical to the Citico, the Pisgah puts Litespeed performance into service for any cross-country, single-speed, or urban MTB build. Compatible with both 26" and 650b wheels. [15] Sewanee: A full-suspension cross country race bike, the latest Sewanee features 90 mm of rear travel in a cold-worked 3Al/2.5V titanium frame ...
The structure of the bike is formed from moulded carbon-fiber that is bonded into 3D printed titanium joins. Hope also developed a way to build custom disc wheels for the bike using a monocoque structure, resulting in them weighing less than 700g. [15] The bike cost over £15,000 to produce. [16]
The difference between the two can be seen by the depth of mounting grooves on the bottom bracket spindle. v1 spline grooves are 5 mm long, while v2 grooves are 9 mm long. Shimano 105, Ultegra 6500 and Dura Ace 7700 cranksets mate to v1 spindles, while later mountain bike designs use the deeper-grooved v2.
Single speed bicycles and fixed-gear bicycles are popular with bicycle messengers for their reliability and durability. [2] Depending on the situation, a messenger may prefer a mountain bike based single-speed, which can roll over many obstacles, or a fast and light road bike-based single-speed.
