Mountain Bike Rims
Rims & Wheels Wheels are obviously vital and come in many different forms and materials. They are made in 3 main sizes; 26" for MTB bike, 700c for the road and 20" for BMX. Fitting onto the rims are tyres which are either self contained (such as tubular tyres) or inflate with tubes in the tyre. The wheels themselves are made up of rims, hubs and spokes. The main point of contact between the rider and bike is with the saddle attached to a seat post into the frame and handlebars with grips or bar tape. A stem attaches to the frame and allows the position to be adjusted to the different size of the rider.
