The purpose of bib shorts is simple - they prevent your shorts from riding down when you're in a low riding position without requiring a restrictive waistband.
Well, not exactly. Over the years, an explosion in innovation and development has made the bib short essential, providing new levels of comfort and performance for cyclists of all levels. They're versatility and simplicity has seen them adopted across almost all cycling disciplines, while fabrics and features continue to be developed.
Anatomy of the bib short
No matter your riding discipline, experience, or the current conditions, there is a bib short to suit your needs. Here's just some of the main features and elements you need to become acquainted with.
The seat pad, or chamois, is the secret to the success of the modern bib short. Shaped to fit the vulnerable parts of male and female riders, they prevent chaffing through excess rubbing or clamminess. Few experienced cyclists would even consider cycling long miles without a quality chamois, and those who have are likely to have regretted it.
One element to consider is the thickness of the pad, although it's worth noting that thicker material does not necessarily mean more comfort.
And - before you ask - no, you never wear underwear under bib shorts.
It’s worth noting that chamois care is essential to prolong their lifespan. Post-ride washing is obligatory while many cyclists carry out pre-ride chamois treatments, rubbing on cooling and moisturising chamois cream either directly onto the garment or themselves.
The bib shorts fit
Bibs come in a variety of lengths, but whether you want on the knee, high on the thigh, or somewhere in between is really up to you. In terms of overall fit, however, you should aim for your bibs to be like a second skin, worn tight to the body. Loose material or gaps can cause chaffing and put an end to any ambitious rides over long distances. Having said that, there are many different types of bodies out there and many bib shorts accommodate this with different levels of fit - profit, performance, and active fit.
- Pro fit: These are super tight, providing the highest level of aerodynamic advantage.
- Performance fit: A little more forgiving and comfortable than pro fit, but still offering performance benefits.
- Active fit: Much more relaxed in terms of fit, and a good choice for beginners or those style getting down to their performance weight.
Common features found in bib shorts
Depending on your level of experience, you can take advantage of a variety of features, offering everything from a more aerodynamic profile to fabrics that combat cold weather.
Seamless bib straps reduce chaffing and reduce wind resistance. Breathable materials ensure you stay cool even when hammering up a steep climb. Flatlock seams provide an aerodynamic advantage, while four-way stretch materials ensure comfort and ease of movement.
An important addition for many is the inclusion of quality leg grippers to prevent the shorts creeping up on your thigh and causing discomfort - this can be very frustrating on long rides.
There are also a number of women-specific features, such as the halterneck style straps which make it a lot easier to get out of the shorts when you take a loo stop at the cafe.
If you're likely to be riding in cold conditions, then look for fleece-backed shorts and water repellent fabrics - perfect for riding through spring showers and autumn downpours.
Do I need bib shorts?
If you’re riding for a reasonably long time, bib shorts provide a wealth of benefits. Their usefulness has ensured their popularity among road cyclists, mountain bikers, and adventure riders alike, while the comfort of a good chamois is unrivalled when compared to your everyday underwear and shorts.
What’s the difference between MTB and road bib shorts?
The main difference between the bib shorts of both disciplines is the cut and chamois placement. Mountain bike shorts will have a more central chamois, designed for a more upright seat position, while road shorts are designed for long periods spent in the lower forward hunch. MTB bib shorts will also favour durability over weight-saving and tend to be slightly thicker and more resistant to scraping or ripping.
While bib shorts are an accepted part of the uniform for road cyclists, MTB and casual riders still tend to wear baggies over the top of their Lycra layer.
What are the differences between male and female bib shorts?
Female bib shorts have a differently contoured chamois to provide more appropriate support for the female form. A different approach to the shoulder braces is also becoming increasingly common to limit chaffing using a centrally positioned brace. Halterneck options are equally gaining pace, allowing easier loo breaks for female riders.

Can you machine wash cycling shorts?
Of course! Modern cycling shorts are machine washable.
Can you tumble dry cycling shorts?
Yes, but keep to a low setting, such as a sports or synthetics setting. The garment should still be slightly damp when you take it out before hanging it until the drying is complete.
How important is compression when buying cycling shorts?
The general rule is tighter is better - any loose material can start to rub and cause painful chafing, especially when out on a monster ride. Compression shorts are designed to aid blood flow and recovery, but not all cyclists agree that compression is key. It will largely depend on your own tastes on whether you want to go for a short with a lot of compression.
What do you wear under cycling and bib shorts?
Nothing! If you're wearing any sort of underwear under your cycling shorts, you're negating their benefit. You should have nothing against the skin except short, chamois, and some chamois cream if needed. Any extra layers or materials will cause chafing, which is exactly what the shorts are designed to counteract - and that means not even a g-string.
