When it comes to clothing the bib shorts are an unknown to the newer cyclist,  I to fell into the same group and I hope this helps set things straight.

You have two options when it comes to the shorts area, you can either wear shorts or bib shorts.  The difference is quite large and in its own right a huge difference.

Bib shorts are designed to cover the lower back and to go over the shoulders keeping them from falling down.  Even in the summer months a cold draught  around the lower back can cause more problems than you think.  Wearing bib shorts prevents this from becoming a problem.

Choosing the right clothing is key to a comfortable ride and body care, remember never double up.  You should only wear the shorts and the shorts alone.

The pad is shaped to conform to the body, and provide padding where you make contact with the saddle. The most important areas are where the sit bones make contact with the saddle. Cheaper shorts might have a single thickness pad, while the more expensive pads use variable levels of foam thickness and density to keep the pad thinner where you don’t need much cushioning, and more padding where you do need it. Such pads are generally more comfortably as a result.

Look for a pad with antibacterial finish for hygiene, to things from getting messy down there. Some pads have channels or perforations to wick away sweat; there’s nothing more uncomfortable than a soggy pad. The pad should feel reasonably soft and have some flex to it, so it shapes to your body. It needs to sit flush with your curves so in a way it’s part of you. You don’t want to sit on top of the pad. The better pads we’ve tested tend to feel like they’re not there at all.

Moving away from the pad, the fabric and fit are really important to your comfort. The fit is influenced by the number of panels used to make the shorts. There more panels there are, the more complex the shorts are to make, and so they cost more.

The most common fabric for bib shorts is some sort of stretchy synthetic mix, usually a blend of Nylon and Lycra, ad variously described as spandex or Elastane. There’s a huge variety of thickness and weights of fabric, though.

You really don’t want shorts riding up and exposing your tan line so they usually have some sort of gripper to keep them in place on your legs. Silicone tape or dots are the most frequent solutions, along with elasticated hems.

This year’s Indian summer has provided the perfect opportunity to test dhb’s Professional ASV Roubaix bib short. The bibs are a fleece lined version of the standard dhb ASV shorts, owing to inclusion of “Roubaix” in the name.

These shorts are high quality, being the same specification as worn by the Wiggle Honda Pro Team. They are designed to be used in spring or autumn and are ideal for when the weather turns colder, but not quite cold enough to warrant full tights.

For racers who prefer the freedom of movement you receive when choosing shorts over tights, these bibshorts are ideal.
