Mountain bike cycling shorts
MTB cycling shorts protect your seat on cross-country trails: their chamois pad absorbs vibration and limits friction against the saddle. Mavic mountain bike cycling shorts for men and women cover rides from up to 3 hours to 7 hours and more, and every women's model has a chamois pad shaped for the female body.
MTB cycling shorts for men and women: which for XC?
For men's or women's cross-country shorts, look first at the chamois pad: ErgoEssential up to 3 hours, ErgoContact up to 7 hours, ErgoEndurance for 7 hours and more.
Under UCI rules, an elite XCO World Cup race lasts 80 to 100 minutes, well within the 3 hours of the ErgoEssential pad. Our guide explains how to choose cycling shorts in detail.
For each Mavic model, check the pad first, then the cut and the fabric.

XC shorts: position, attacks and riding out of the saddle
In cross-country, you slide onto the nose of the saddle on steep climbs and attack out of the saddle, so your XC bib shorts must follow you without riding up your thighs.
The ErgoEssential and ErgoContact pads of the Aksium and Cosmic models are shaped so you forget them out of the saddle. When you accelerate, MTB shoes with cleats keep your foot locked to the pedal.
On a singletrack, a bramble or a slide can scuff your shorts: the Cosmic Pro, Cosmic Ultimate and Allroad Cargo Bib Short Men use an abrasion-resistant fabric.
MTB bib shorts for riding out of the saddle
Bib shorts stay put when you ride standing, even under MTB shorts: the straps hold the pad without squeezing your waist.
Waistband shorts: Aksium Short for men and women
The Aksium Short Men and Aksium Short Women have no straps and stay in place with a waistband across the abdomen. The Aksium Short Women has a short 20 cm inseam for more freedom of movement.
Chamois pad: shocks, vibration and friction on the trail
The chamois pad in your shorts absorbs vibration from roots and rock gardens when you pedal seated on a rough trail, and reduces friction against the saddle.
On a hardtail, with no rear suspension, root impacts travel through the cross-country mountain bike wheels and the frame straight to the saddle.
The four-layer ErgoEndurance pad of the Ksyrium and Allroad Cargo models, with its OrthoLite insert, spreads pressure evenly and absorbs vibration; on the Ksyrium Bib Short Men and Allroad Cargo Bib Short Men, it also suits riders over 75 kg. To avoid pressure points, the Cosmic Ultimate Bib Short Men has a seamless construction.
Long-distance MTB and XCM marathon: which pad?
For an XCM marathon, between 60 and 160 km under UCI rules, choose an ErgoContact pad, made for rides up to 7 hours, or an ErgoEndurance pad, made for 7 hours and more.
By the fifth hour in the saddle, pad quality matters far more than on a short after-work loop. The compressive fabric of the Cosmic Pro Bib Short Men supports your muscles to limit fatigue over the distance.
To refuel without a backpack, the Allroad Cargo Bib Short Men has two side pockets for your phone and race food.
Winter bib tights for cold rides and muddy trails
Long bib tights keep your legs warm: fleece Aksium Thermo models for rides under 15 °C, Superroubaix Ksyrium Thermo and Cosmic Thermo tights for winter.
On waterlogged trails in January, the DWR treatment of the Ksyrium Thermo and Cosmic Thermo models keeps splashes and light rain off your legs.
In spring and autumn, the Aksium Knicker Women (10 to 20 °C) and the Cosmic Thermo Bib Short Men suit chilly mornings. On top, layer up with a long-sleeved MTB jersey, then a windproof jacket over it, depending on the temperature.
