The larger diameter thread on the fixed side accepts a standard threaded cog and uses the same size threads as the freewheel side of the hub. The most common standard I.S.O. thread size is 1.375" x 24 tpi (threads per inch), but there are other less common older sizes (British 1.371" x 24 TPI, French 34.7 x 1 mm, Italian 35 mm x 24 TPI).
The wheel size is sometimes erroneously called "650B" [8] [9] as a "marketing term" by some manufacturers for their 27.5", but the 650B size has traditionally been a designation for a 26 inch diameter (ISO ~ 40-584 demi-ballon tire) using the same ISO 584 mm rim [10] used by French tandems, Porteurs and touring bicycles.
650C - ISO 44-571 (26 ⋅ 1 + 3 ⁄ 4) - Formerly 47mm wide on Schwinn cruisers and for British trade/delivery bikes. Currently ISO 28-571, size is the same, but the narrower and less overall wheel diameter are built for triathlon, time trial and small road bikes.
ISO 5775 is an international standard for labeling the size of bicycle tires and rims.The system used was originally developed by the European Tyre and Rim Technical Organisation (ETRTO).
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.
For example, if a fat-bike tire is inflated to 0.5 bar (50 kPa; 7.3 psi) gauge pressure at room temperature 20 °C (68 °F) and then the temperature is decreased to −10 °C (14 °F) (a 9% decrease in absolute temperature), the absolute pressure of 1.5 bar (150 kPa; 22 psi) will be decreased by 9% to 1.35 bar (135 kPa; 19.6 psi), which ...
rattleCAD is a parametric 2D computer-aided design (CAD) software specific for bicycle design, [1] [2] in particular for design bicycle frame, [3] [4] developed by the Austrian cyclist and programmer Manfred Rosenberger since 2008. [5]
Chain Reaction Cycles started out as a small bike shop named Ballynure Cycles which was opened in 1985 by George and Janice Watson [4] using a £1500 bank loan in the small village of Ballynure in Northern Ireland.
