The Castelli Evoluzione bib shorts is the successor to the Progetto Y which took the world of cycling by storm in 1998.
Built from eight ergonomic panels for a true anatomic construction that fits to your body for comfort and aero performance. Innovative silicone grippers and mesh bibs keep the Evoluzione in place.
New is a ProDry 2Strati fabric which uses a polyester inner layer with a nylon outer to help transfer moisture away from the skin leaving you dry and more comfortable. The KISS Air seat pad supports your sensitive areas to keep you in the saddle for longer.
Recently purchased a pair of these to wear on a trip in Greece. Only covered 25k and 50k rides so not tested on a long ride yet but involved a fair degree of climbing at 28 degrees. Comfort is very good. I've been using the Entrata FZ for the last year which have lasted well and are very good. The kiss seat pad in these is more comfortable and the leg grippers are improved although no issues with the Entrata. Delivery was quick and efficient and the price from Tredz is a bargain. Great time to buy. Sizing I'm 5'9" and 70K and I take Large.

If you've ever spent a long time in the saddle you'll know how uncomfortable wearing casual shorts can be. They chafe, fit poorly and offer little mobility. Cycling shorts make all the difference.
Most cycling shorts come with a padded insert known as a chamois. This insert relieves pressure in your sensitive areas and stops numbness.
Bike shorts are anatomically designed, often with a longer and higher cut at the back for when you’re in a riding position. This means you have a far more comfortable ride.
Lycra shorts will be snug with some stretch for aero performance and mobility. Casual baggies offer maximum freedom of movement for demanding trail riding.
Cycle shorts use performance fabrics such as lycra and nylon.
Lycra is quick wicking to help transfer moisture away from the body.
Nylon is bombproof for durable riding.
These fabrics offer some stretch for added mobility and flat stitching is smooth against your skin to reduce chafing.
Added features such as Teflon coating or Ripstop improve durability.
Lycra shorts | Ideal for road cycling
Lycra shorts (and bib shorts) offer the best comfort in the saddle. You wear these directly next to your skin – no underwear.
Lycra is quick drying and worn close against the skin meaning the chamois stays in place as you ride.
Leg grippers also help to keep the shorts in place.
Bib shorts | Ideal for road cycling
Bib shorts are similar to standard waist high lycra shorts. However, you also get supporting shoulder braces.
As there is no waist line to dig in to your stomach they are more comfortable. Bibs are pulled taught ensuring the chamois stays where you want it.
Baggy shorts | Ideal for mountain biking
Baggy shorts are popular because of the more casual style which also keeps your modesty in check.
Baggy shorts are more durable with fabrics designed not to rip and tear from branches or debris.
Slip knee pads under these shorts for extra protection. Plenty of pockets are ideal for stashing tools and nutrition.
Not all baggy shorts come with a pad but you can easily fit a pair of padded undershorts underneath.
Undershorts | Ideal for mountain biking
Undershorts are thin liners with an added chamois pads. Slip these under baggy or casual shorts extra comfort and protection in the saddle.
