Cross country (XC) mountain bikes usually have only a small amount of front and/or rear suspension (usually 65-110 mm) and are relatively light, which is achieved via the use of lightweight materials and construction in both frame and components. As a consequence, XC bikes are often less durable than other types of mountain bikes when used outside of their intended purpose.[citation needed] On full-suspension XC bikes, both front and rear, is typically provided by pneumatic (air) shocks or smaller coil/oil shocks and forks, which saves weight. Some full-suspension XC bikes may weigh as little as 21 pounds (9.5 kg). Other XC bikes have only front suspension, and are normally referred to as hardtails. A few XC bike models have no suspension and use a rigid front fork, saving weight but relying more on rider skill to negotiate rough terrain. XC or general riding is the most popular form of mountain biking, focused on climbing and quick turning abilities rather than on the aggressive descent capabilities of freeride or single-purpose downhill mountain bikes. XC bikes reflect this in their lighter weights and steeper geometries. However, due to their lighter frames and suspension, most XC bikes are poor choices for heavy-impact activities such as jumps and high-speed traverse of large obstacles such as rocks and deep washouts.

MTB ir plašāks jēdziens un apvieno visu, kas saistās ar kalnu velosipēdiem, - sākot ar tehniku, beidzot ar pašu braukšanu. XC ir jau konkrēta disciplīna MTB ietvaros, ja tā var izteikties. No tāda viedokļa termins "MTB sacensības" ir piemērots tikai gadījumos, kad tas jāatšķir no, teiksim, slēpošanas vai skriešanas, jo ir skaidrs, ka būs jābrauc ar kalnu velosipēdiem. XC ir korektāks termins, jo precīzāk raksturo, tieši kāda veida MTB braukšana būs.

Latvijā mums ir divu veidu XC disciplīnas XCO un XCM.
XCO apzīmē olimpisko krosu. Tā ir sacensība pa 5-9km apļiem sarežģītā un grūtā trasē. Distancē pavadītais laiks no 1,5 līdz 2h. Vidējais ātrums ir diezgan zems.
XCM apzīmē XC maratonu. Tā ir 60-120km gara viena apļa distance sarežģītā un grūtā trasē. Vidējais ātrums parasti nedaudz lielāks par XCO.

Latvijā sacensību nosaukumos liek XC?, lai tādā veidā demonstrētu vēlmi tuvoties UCI XCO un XCM definīcijām un vidējiem ātrumiem.

un triāls

maratons ir maratons, xc ir xc. ko tur pielidzinat?

barjersprintu pielidzinat skepa mesanai, jo abi stadionā?
