Cycling bib shorts

Bib shorts are part of the classic, slick cycling look that comprises of clean lines, aero fitting, and air-slicing clothing.

The bib short’s popularity is due to its simple solution to some basic problems – how do you achieve this slick line and aero fit without an uncomfortable and restrictive waistband, and, how do you prevent your shorts from riding down while you’re in the drops?

Two shoulder straps solved a variety of problems in one fell swoop and the bib short was born, adopted by road cyclists the world over.

It combines a range of innovations into one multi-purpose design, solving many problems in one go. That’s why these shorts have become popular among cyclists both on the road and on the trails.

Do I need bib shorts?

If you’re riding long miles – over an hour at a time – or spend a long time on the trail in cold weather, then bib shorts are a no brainer.

Not only do they act as a second skin, but they also incorporate a chamois to provide extra comfort and limit chafing during long spells on the saddle.

They act as an important part of the cyclist’s base layers, ensuring you stay warm, while giving you the freedom of movement to deliver a strong performance while you’re out there.

So, if you’re serious about cycling, then a pair of quality bib shorts is essential.


What makes a good set of bib shorts?

Lightweight and snug to the skin, Lycra shorts are the most comfortable and aerodynamic option for long, pedal-intensive riding.

Modern shorts are made from breathable materials that allow water vapour to escape through the fabric, and drawing away sweat to limit discomfort and chafing.

High-quality bib shorts are made from a number of individual panels that aid the best possible fit, and it’s the fit that can make all the difference in finding the perfect shorts.

Chamois quality is also of vital importance. This padded material lines the gusset of the shorts, providing padding between the touch points of the saddle, your sit bones, and delicate parts.

Premium shorts come with contoured, multi-density padding that’s more supple and comfortable on long rides and less prone to bacterial build-up and odour.

It’s worth noting that chamois care is essential to prolonging the life of any shorts. 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 for both comfort and long life.

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 more aggressive 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.

Frequently asked questions about bib shorts

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 until 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. 

Why are cycling shorts always black?

Due to the revealing nature of super slinky cycling shorts, the general consensus has arisen that dark colours are essential for maintaining as much dignity as possible. Navy shorts have been growing in popularity recently, and are worth a look for the season ahead.
