Many mountain bikes have a full suspension design. In the past, mountain bikes had a rigid frame and a rigid fork. In the early 1990s, mountain bikes started to have front suspension forks. This made riding on rough terrain easier on a rider's arms. The first suspension forks had about 1 1 ⁄ 2 to 2 inches (38 to 50 mm) of suspension travel ...
Suspension fork design has advanced in recent years with suspension forks becoming increasingly sophisticated and diverse in design. The amount of suspension travel available has increased over time. When suspension forks were introduced, 80–100 mm of travel was deemed sufficient for a downhill mountain bike.
Paul began developing the first bicycle suspension fork. In 1989 or 1990, Turner approached Simons for help designing a suspension fork for mountain bikes. Turner had in 1987, with the help of Keith Bontrager, presented a full bike with front and rear suspension at the bicycle industry trade show in Long Beach. The industry was not impressed.
Fox naming of the forks relies on the stanchion diameter, and the available models are 32, 36, 38 and 40. These can have different dampers, depending on the quality of the dampner; Grip/Grip2, Fit GRIP/Fit4, GripX/X2, which provide different ranges of adjustability of both high and low speed compression and rebound.
Due to front fork suspension, modern mountain bikes—as opposed to road bikes—tend to have slacker head tube angles, generally around 70°, although they can be as low as 62° (depending on frame geometry setting). [3] At least one manufacturer, Cane Creek, offers an after-market threadless headset that enables changing the head angle. [4]
These are more commonly seen on BMX and mountain bikes; Hanger: part of frame or an attachment to the frame to which the derailleur is attached (see Derailleur hanger) Handlebar: a lever attached, usually using an intermediary stem, to the steerer tube of the fork. Allows steering and provides a point of attachment for controls and accessories
Blur - 29" wheels, 2 options for suspension travel: XC and TR. TR has 120 millimetres (4.7 in) of fork travel, and 115 millimetres (4.5 in) of VPP Travel. XC has 110 millimetres (4.3 in) of fork travel, and has 107 (4.2 in) millimetres in VPP Travel [ 12 ] (Re-introduced in 2018)
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 ...
