Ban pit

Ban pit iku sawijining ban sing dipasang ing rodha sawijining pit, pit rodha tunggal, pit rodha telu, pit rodha papat, lan jinis pit liyané. Kadhangkala ban iki uga dianggo ing kursi rodha. Ban pit iku wigati banget tumrap empuké utawa suspènsi nalia numpak pit.

Ban pit modhèren bisa diklasifikasi miturut sawatara kritéria:
 miturut cara nèmpèlé ing pèleg: clincher utawa tubular,
 cara panyimpenan hawa: tabung, tanpa tabung (tanpa ban njero) utawa padhet/dholog,
 Jinis benang: slick utawa knobby.

Ukuran
Ukuran ban modhèren (kaya "37-622", uga kaloka minangka ETRTO) diatur nganggo baku internasional  ISO 5775, bebarengan karo baku ukuran rodha pit (tuladha "622×19C"). Older English (inch, e.g. "28×1-5/8×1-3/8") and French (metric, e.g. "700x35C") designations are also still used, but can be ambiguous. The diameter of the tire must match the diameter of the rim, but the width of the tire only has to be in the range of widths appropriate for the width of the rim. Diameters vary from a large 910 mm, for touring unicycles, to a small 125 mm, for roller skiing. Widths vary from a narrow 18 mm to a wide 119 mm for the Surly Big Fat Larry.

Tekanan ban
Tekanan ban pit wiwit saka sangisoré  tumrap ban njero pit gunung (tubeless) nganti  tumrap ban pit balap. The pressure rating of tires is usually stamped somewhere on the sidewall. It may be indicated as "Maximum Pressure," or "Inflate to... " and is usually expressed as a range (for example, "". Inflating to the lower number in the pressure range will tend to increase traction and make the ride more comfortable. Inflating to the higher number will tend to make the ride more efficient and will decrease the chances of getting a flat tire.

One published guideline for clincher inflation pressure is to pick the value for each wheel that produces a 15% reduction in the distance between that wheel rim and the ground between loaded (i.e. with the rider) and unloaded. Pressures below this lead to increased rolling resistance and likelihood of pinch-flats. Pressures above this lead to less rolling resistance in the tire itself, but to larger energy losses in the frame and rider. Bicycle tires are essentially thin-walled pressure vessels and so the circumferential force in the casing is directly proportional to the internal pressure and to the tire diameter, and the force in the longitudinal direction is half of this.

Ban njero ora bener-bener anti bocor, lan kanthi alamiah bakal kempès baka sethithik. Ban njero saka butyl luwih anti bocor tinimbang saka bahan karè latèks. At least one public bicycle sharing system, Bixi, is inflating tires with nitrogen, instead of simple air, which is already 78% nitrogen, in an attempt to keep the tires at the proper inflation pressure longer, though the effectiveness of this is debatable.
