dhb Aeron Speed bib shorts
9 10

The dhb Aeron Speed shorts are very good value for money with no compromises, and come highly recommended if you want a long-lasting, tech-packed pair of bib shorts for training and racing in the warmer months.

dhb says the Aeron Speed is its most technical bib short to date, with 'over ten years of experience and development' going into the finished product. They're at the top end of its apparel range, and for a brand more associated with budget clothing its technical performance wear really holds its own with pricier products.

They're intended for spring and summer riding, coming with Coldblack technology to help with cooling, which works by detracting the heat away from black/dark fabrics. A mesh panel on the back also helps with ventilation.

They're made with 'Revolutional Energy' fabric, which offers a tight fit that is also purported to be compressive, although I didn't feel any compressive benefits myself – I found that they're fairly close-fitting but not necessarily compressive tight. The wide silicone grippers grip the legs nicely without squeezing them too much – this should be the way forward with all cycling shorts nowadays in my opinion, there's no longer the need for tight squidgy silicone when the wider, more subtle stuff fits so well.

I did find these shorts a little longer in the leg than most bib shorts, so if you like your shorts shorter it might be worth erring on the smaller size if you're in between. Most of the seams are flatlock stitched, and the only place where I saw any weakness in construction was where the bib straps are stitched onto the body of the shorts; these stitches are exposed and could wear over time.

Performance-wise, the shorts were great in warm conditions, with the Coldblack technology really getting to work. They also dried quickly after some wet rides, and provided plenty of comfort on rides of four hours or more with no chafing to report.

The chamois pad is thermomoulded and has a minimalist, flat design and soft polyamide construction; it's big enough without feeling at all weighty or cumbersome. It's nice and dense, too, so it won't lose its shape or degrade over time. The seams around it are flatlocked to avoid annoying saddle sores, and it's built with a 'wing' arrangement with a central pad to assist with blood flow to your nether regions. Good news all round!

The red lining has kept its colour in multiple washes, and I've not experienced any bobbling or bunching up of the fabric in the legs as I've experienced with some bib shorts.

In terms of price, they're good value compared to bibs with similar performance benefits – Endura's Pro SL II bib shorts are £119.99, and although I can't vouch for the latest update I found the previous version of these shorts weren't as comfortable as dhb's offering here. BTwin's Aerofits are a very good shout at £55 – if the sizes available suit you. Elsewhere, you're looking at £139.99 for a pair of Castelli's Free Aero shorts, and £149.99 for Gore's Oxygens – both of which offer similar moisture management properties and highly engineered chamois pads.

Overall, I was really happy with the fit and comfort offered by the Aeron Speed shorts, and at £80 they're comparatively good value for technical race shorts.
