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.
A mountain bike with 29″ wheels is often referred to as a 29er, and a bike with 27.5-inch wheels is called a 27.5 Mountain bike or as a marketing term ″650B bike". [ 27 ] Wheels come in a variety of widths, ranging from standard rims suitable for use with tires in the 1.90 to 2.10 in (48 to 53 mm ) size, to 2.35 and 3.00 in (60 and 76 mm ...
The average 29-inch mountain bike tire is ISO 59-622 - corresponding to an outside diameter of about 29.15 inches (740 mm). 32 inch / ISO 686 32-inch wheels have been in use on unicycles and have been appropriated for bicycles to create bikes more proportional for taller riders.
The Super V, a full-suspension bike, is arguably Cannondale's most iconic mountain bike. Instead of a main triangle, Cannondale uses a massively oversized down tube and a mast to hold the seat. The rear wheel is suspended by a banana-shaped aluminum high-pivot swingarm providing about 75 mm of travel. The front wheel is guided by a Delta V fork.

Wheel size optionality with disc brakes allows the rider more options, including using a smaller diameter rim-sized wheel (such as 27.5″+) with a higher volume wider tire with the same outer diameter size as a larger rim-sized wheel (such as 29″) – the outer diameter consistency is important as it preserves the geometry of the frame ...
29″ and 26″ mountain bike wheels. 29er rims have an interior diameter of 622 millimetres (24.5 in) [1] and the average 29″ mountain bike tire is (in ISO notation) 59-622 – corresponding to an outside diameter of about 29.15 inches (740 mm). The typical 26″ MTB tire has a rim diameter of 559 millimetres (22.0 in) and an outside tire ...
The order of installation of a typical headset follows. The steerer tube is cut to the appropriate length by the bicycle fork manufacturer and the top 25–51 mm (1–2 in) of the steerer is threaded using a rolling process. This process assures that no material is lost and the steerer would not be weakened as with a die or lathe cutting.
