    Stem: a bracket used to attach handlebars to steerer tube of fork. Usually secured by pinch bolts; Tire: as in common usage. Usually pneumatic. A tubular tire is glued to the wheel rim; most tires use tubes, but tubeless tires and rims are increasingly common; Toe clips: a metal or plastic cage attached to a pedal. Usually has an adjustment strap.

    The nominal width of a rim is the inner width between the straight sides or beads as one can easily measure it with a caliper (see the standard for drawings and exact measurement procedures). The standard widths of straight-side rims are: 18, 20, 22, 24, 27, 30.5. The standard widths of crochet-type rims are: 13C, 15C, 16C, 17C, 19C, 21C, 23C, 25C

    A separate airtight inner tube enclosed by the tire supports the tire carcass and maintains the bead lock. An advantage of this system is that the inner tube can be easily accessed for a patch repair or replacement of the tube. The ISO 5775-2 standard defines designations for bicycle rims. It distinguishes between Straight-side (SS) rims

    A diagram showing the effect of decreasing the head tube angle, the fork offset, or the wheel size (diameter) on the trail. Animation showing how fork offset must change with changes in steering axis angle to keep trail constant.

    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.

    Fitting rim tape around 26 inch wheel (MTB). Rim tape protects the bicycle wheel's inner tube from spoke holes, which will puncture the tube if exposed inside the rim. Most bicycle rims are "clincher" rims for use with clincher tires. These tires have a wire or aramid (Kevlar or Twaron) fiber bead that interlocks with flanges in the rim. A ...

    The larger diameter of the head tube and headset gives added stiffness to the steering portion of the bicycle. Common sizes. 25.4 mm (1 in) steerer tube, this may have a fork crown (the base of the fork steerer tube) of a number of different dimensions, and milling may be necessary to make some headsets fit. 26.4 mm crown race (ISO standard)

    Larger wheels roll over obstacles more easily. The ability of a wheel to roll over obstacles is proportional to its size. A 29″ wheel, which is about 10% larger than a 26″ wheel, can roll over 10% larger obstacles. [citation needed] The larger diameter wheels have more angular momentum so they lose less speed to obstacles and rough sections.
