Technical Information

Bibless undershorts can be much more practical. But do you get enough support? To guarantee the support you need, even without straps, we have made a pair of undershorts that hugs your body just like boxers. The elasticated waistband adapts to fit you and stays in place with no adjustment needed. And to stop the shorts riding up as you cycle along, there are gel bands at the bottom to keep your undershorts just above your knee.
Feeling comfortable in the saddle is a top priority when you're on the go for several hours! For maximum comfort, even when you're hurtling down mountain bike trails, your undershorts have an ergonomic 12 mm foam pad. Besides making the saddle more comfortable, the pad reduces rubbing so you won't get chafed.
Several layers for less heat?
In the middle of summer in particular, you need to get rid of heat quickly. That's why the ST 500 undershorts have a breathable foam pad and mesh fabric, to wick away perspiration quickly. The result is that you don't warm up, even though you're wearing two layers of shorts.
How our ideas and your feedback made these undershorts.
We entrusted our mountain biking team with the task of designing bibless undershorts that give you a good balance between simplicity and support. It took five people 18 months of studying, designing, prototyping and running lab tests... And we also had your feedback. We travelled to France and Italy to meet up with around 30 intermediate mountain bikers and run a series of functional tests in real situations. The result was a product that's suited to your sport and meets your needs!
Shorts, undershorts, pad? Here are our tips!
Undershorts are to MTB what kilts are to Scotland: you wear them against your skin! To avoid chafing, we therefore recommend changing them and washing them as if they were underwear. And when you're riding, your shorts and undershorts should never be attached. Why? Because each has their own role to play: - The undershorts stay in place for comfort and support. - The shorts move with you for better freedom as you cycle along.
