At road.cc every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.What the road.cc scores mean
Good scores are more common than bad, because fortunately good products are more common than bad.
The Triban RC500 Bib Shorts are an impressive package, especially at this price point. Well made and extremely comfortable, they also feature some touring-friendly tweaks that I wasn't expecting.
The build quality feels reassuringly solid – better, in fact, than several I've got commanding twice the money – with neatly executed and unobtrusive stitching and seams. I would happily choose these for a gravel-biased ride. Besides, I doubt Decathlon would whack on a two-year warranty if it wasn't confident they'd last.
The legs are made from 80% polyamide, 20% elastane, while the mesh bibs are 77% poyester, 23% elastane, designed with easy movement and efficient moisture management in mind.
Plenty of smiles per mile here. The stretchy bib sections offer unhampered movement without any distracting slip on longer rides, while the relatively thin panels do an excellent job of trafficking moisture from the skin and, conversely, trapping some welcome warmth when the temperatures dipped unexpectedly, late evening.
Sure, a mild mistiness will creep in given 40 minutes or so at a decent tempo, but this is spirited away soon afterward. Odour management is good too – even after a day's steady riding, nasty niffs were a moot point.
According to the blurb, there's no fatigue-cheating 'compression' technology, although, like for like, they were on a par with a couple that do. This may be partly attributable to the broad silicone gripper. For me this was on the snug side but hasn't presented any problems, and is infinitely preferable to a loose-fitting example that can permit the fabric to ride up, inducing chafing/similar discomfort.
Though they did 'creep' slightly as the miles racked up, I concluded that the mediums were slightly shorter in the leg than ideal for me. (It's not me in the photos.)
Arguably, pads are the most crucial determinant of shorts' comfort. Most are very good by degrees, these days. Decathlon describes it as being a 'gel' design. It is, in fact, polyamide sandwiched between a polyester/elastane mix with a variety of densities to provide optimal support and minimise chafing.
Like many others, it initially felt like the proverbial loaf of bread, especially post-washing. However, it quickly morphed to my shape and went unnoticed, regardless of whether I was doing a sub-30 minute 10 on my TT bike or indulging in an 80-mile mixed terrain meander on my tubby tourer.
The outer fabric permits subtle shuffling/shifting position without distracting slip, irrespective of saddle cover type.
Unusually, the right leg has a pocket – something of a rarity, although I have a pair of Polaris Challenge Nexus shorts which also have this feature, as do, at the other end of the scale, Rapha's Core Cargo bibs. It's a welcome plus, provided you load it sensibly – cash/patches and other little valuables you might need easy access to. (They're available without, too, if you prefer.)
The backs feature a smattering of discreet retro-reflective detailing.
Ours were medium and, on balance, I think I might be between sizes. These were slightly shorter in the leg than I'd prefer. Decathlon's sizing chart is reassuringly accurate, so in all probability online purchases shouldn't present any unexpected surprises.
At a penny under £40, these shorts are really good value for what you get. They're not alone at this end of the scale – dhb's lowest priced bib shorts come with a Cytech pad and silicone leg grippers and, at £35, could give the Tribans a good run for your hard-earned.
Caratti's Sport Bib Shorts are £40, though the test sample's stitching lacked the Triban's refinement.
Ultimately, the Triban RC 500s represent excellent value for money and are, thus far, on a par with some in my collection costing twice as much. A lot of thought seems to have gone into their design. Just beware you might have to go up a size if you have sprinter-esque thighs or fall between sizes.
Really good, competitively priced riding staples – but check the sizing

Well made and built to last.
Very comfortable in all contexts. Mesh panelling does a good job of regulating temperature on hotter days, too.
Very solidly made and backed with a two-year warranty.
Generally excellent fit. Figure-hugging, yet tactile and compliant.
Slightly shorter in the leg than ideal for me. You might need to go up a size.
Very comfortable in all contexts, despite being slightly shorter in the leg than ideal for me.
How easy is the product to care for? How did it respond to being washed?
Much as any other bib shorts: pop in the wash, minimum detergent, 30 degrees and line dry.
Tell us how the product performed overall when used for its designed purpose
Deliver phenomenal bang for very modest buck and have performed consistently well, regardless of what machine and type of riding. The pad is particularly good, offering just the right blend of comfort and density. Large silicone grippers keep the shorts from gathering, without encroaching. Moisture management is similarly good, mesh bib panels trafficking moisture very efficiently.
Tell us what you particularly liked about the product
Specification and comfort very high, relative to the price point.
Tell us what you particularly disliked about the product
Not a dislike per se, just a caution re the sizing.
