B'Twin has developed an excellent reputation for good products at great value prices and the B'Twin Aerofit bibshorts continue that trend. Previously, other products that have really impressed us include the B'Twin 700 Shoes and Triban 540 bike.

For reference, I opted for a size medium and am 6ft 1in and 71kg and the fit was good. There was no chafe-inducing bunching in the undercarriage region and I was particularly impressed with the grippers. They are elastic and wide, being made from a special fabric. In terms of quality they are right up there with many shorts around the £80 mark. The straps offer good stretch and sit flat too.

I still rate the excellent Endura Pro SL bib shorts higher on the comfort scale, but they do cost nearly twice the price at £100.

I like the way they look too, especially when paired with the corresponding jersey. It's good-looking kit. Considering the price and performance offered, most cyclists have little to lose by investing in a pair of these. If you have a favourite pair of rather expensive Assos shorts for example, then the B'Twin Aerofit bib shorts make a great back-up pair.

B'Twin has previously supplied kit to the FDJ pro team and develops clothing with pro riders. Consequently, the B'Twin Aerofit bibshorts are of that standard. If they are good enough for Thibaut Pinot's posterior then they they're good enough for yours! What we have here is pro-level bibshorts at a brilliant price.

My only real criticism is of the lack of colour options. I am sure more people would buy these if they were also available in plain black.
