Cycling shorts are the most important piece of cycling equipment for your comfort in the saddle. It is the shorts, and more specifically their chamois, that determine whether your ride ends well or not. However, with a wide range of options and sometimes obscure technical criteria, choosing your cycling shorts can quickly become complicated. This guide gives you all the keys to making the right choice based on your riding style, body shape, and the duration of your rides.
Why are cycling shorts the most important piece of your equipment?
Unlike jerseys or shoes, cycling shorts are in constant contact with your saddle contact area for hours. A poor chamois, poorly placed seams, or unsuitable compression can quickly make the ride uncomfortable, even painful. Conversely, good cycling shorts completely disappear from your perception—you just pedal.
Cycling shorts fulfill four essential functions: cushioning vibrations via the chamois, supporting thigh muscles through compression, preventing chafing with technical seams, and keeping the garment in place via the silicone band and shoulder straps.
Bib shorts or regular shorts?
This is the first question to decide. Both formats have their advantages, but the answer is almost unanimous among regular cyclists:
Bib shorts
Bib shorts are considered the standard for road and gravel cycling. The straps keep the shorts in a high position, preventing the chamois from slipping during exertion. They distribute pressure better and provide constant support regardless of your position on the bike. The downside is that comfort breaks require removing your jersey, a minor inconvenience compared to the gain in comfort.
Regular shorts
Regular cycling shorts are more practical for stops, but often create localized pressure at the waist and tend to slip when leaning forward. They are more suitable for short rides and beginners. For long distances or competition, bib shorts are indispensable.

The chamois: the central part of your cycling shorts
The chamois or pad is the padded insert integrated into the shorts. It absorbs shocks, reduces friction, and protects pressure points in the saddle. Not all brands are equal in this regard.
Types of chamois
Chamois differ in their density and composition. There are three levels:
Single-density chamois (foam or gel) is suitable for short rides and beginner cyclists. It offers basic cushioning without hindering movement.
Double-density chamois (gel + foam) combines two materials for more complete absorption. It adapts better to pressure variations and is suitable for rides of 2 to 4 hours. This is the standard for mid-range cycling shorts.
Triple-density chamois (foam + gel + micro-perforated) is the benchmark for long distances. It adds a micro-perforated layer that promotes ventilation and wicks away moisture, significantly reducing the risk of irritation on rides of 4 hours or more.
Chamois shape
An anatomical pre-shaped chamois conforms to the natural morphology of the cyclist. It positions correctly from the first pedal stroke and does not deform over hours. This is a key criterion for long rides.
A 3D ergonomic chamois goes further: its integrated ventilation channels continuously wick away heat and moisture. It is particularly suitable for hot conditions and competitive efforts.
Chamois brands
Certain chamois brands are renowned in the cycling world. Elastic Interface is one of the most recognized; it produces inserts specifically designed for cycling, with dedicated formulas depending on the discipline and duration of effort.

Compression: what level to choose?
The compression of the cycling shorts fabric plays a role in muscle support and recovery. It comes in three levels:
Light compression
Ideal for leisure rides and cyclists who prioritize comfort over biomechanical efficiency. The fabric wraps without constricting, allows great freedom of movement, and is perfect for occasional rides.
→ Kadenz PACE shorts use light compression — 80% polyamide / 20% elastane. → [Discover PACE]
Medium compression
The right compromise for regular cyclists. It effectively supports thigh and calf muscles without causing additional fatigue. It is suitable for 2 to 4-hour road rides and gran fondos.
→ Kadenz SUMMIT shorts offer medium compression — 70% polyamide / 30% elastane. → [Discover SUMMIT]
High compression
Designed for targeted muscle support during intense, long-distance efforts. It delays muscle fatigue and improves venous return. It is aimed at competitors and cyclists who tackle long gravel or road rides.

Technical criteria to check on cycling shorts
Seams
Seams are the main cause of irritation on cycling shorts. There are three types: classic seams (to be avoided on long rides), flat and invisible overlock seams (quality standard; they blend into the fabric and disappear under the skin), and flatlock heat-sealed seams (the ultimate, no raised seams, zero chafing, a technique used in competition equipment).
Shoulder straps
The shoulder straps of cycling shorts must be micro-perforated to breathe over time. A reinforced back improves support without compressing the shoulders. Check that the straps do not create localized pressure on the collarbones or shoulders.
Silicone gripper
The silicone band at the bottom of the leg keeps the shorts in place, preventing them from riding up during effort. The wider it is, the more stable the support. The presence of a micro-perforated band improves thermal comfort.
Leg hem finish
The laser-cut finish (laser-cut, without peripheral seams) is the best option for comfort. It eliminates any marks on the thigh, even after several hours in the saddle.
Pockets
Most cycling shorts do not have pockets — storage is handled by the jersey. However, some gravel shorts include side pockets on the thighs and a back pocket, useful for long off-road distances.
→ Kadenz WILD shorts have 3 pockets: 2 side pockets on the thighs + 1 back pocket on the buttock. → [Discover WILD]
Men's cycling shorts vs. women's cycling shorts
Women's cycling shorts are not a shortened version of the men's model. The cut is entirely rethought: wider hips, different pelvis, specific saddle position. The women's chamois is repositioned and its shape adapted to female anatomy. On rides longer than an hour, the difference in comfort between unisex shorts and women's shorts is considerable. Always choose shorts designed specifically for your gender.
