RC500 Cycling Bib Shorts - Black
Filtered by translation missing: Loading reviews…
Comfortable but

This bib is comfortable and if you the measurements it fits nicely. Issue is that after a week of usage the seams are coming undone and this only got worst a month matter. Furthermore after less than a month already notice that the chamois is getting worn out on the front and back. Had a cheaper decathlon bib previously that lasted for three years and it’s in better condition than this which is not even a month old!

Bib Shorts

Good fit, comfortable on bike. All I wanted at a good price.

Comfortable and fit well .. loose enough for movement , as I am mainly using these for gravel rides .. so far a few hours in them with no issues

Thin and not stretchy

These came up a bit small compared with other decathlon cycling kit in the same size. Probably because of this, there isn't much additional stretch in them. Also possibly because of this, they are quite see-through from behind (as my horrified ride buddy informed me). Now relegated to solo turbo use. Pad is nice and construction is good.

Have persevered with these shorts for 5 months hoping that they would improve in comfort. However the time has come to admit defeat and consign them to the rag bag. The problem I experience is with the pad insert. The central groove provides a very uncomfortable pinching action and after a short ride of 35-40 miles, my underneath private parts are red raw.

Do not buy

Awful bib shorts, save your money and pay a bit more. Ripped down the seam (located in lower back) after 30miles. Also are extremely see through

Hi James,

I'm sorry to hear about the issue with your bib shorts. A tear down the seam sounds like it could be a manufacturing error, if you bring the item back into store with a receipt we'd be happy to refund or exchange this item for you.


Very poor compared to previous Triban 500

The size of these shorts come up much smaller that the previous ones (I had to replace one set due to small size), and comparable quality is poorer. After just 4 or 5 rides with these shorts the seam has come un-stitched and split, so had to return. My much old set of these that have covered 1000's of km are still going strong, look barely worn and appear to be much higher quality. Always disappointing when a quality product goes down hill.

The first bad Decathlon product I've ever had.

I've had them for about 6 weeks now. I ride endurance and touring. 100-130-mile days weekly, and 20-50 miles daily. No racing. Pros: the pad dampens vibration very well. The silicone grips are very good. Cons: Sizing is way off. I normally wear S or M, size 30 jeans; 5ft 7/10st (170cm/65kg) - and I ended up with L, and still just about tolerable. Should have gone for XL. Ridiculous. The cut is uncomfortable and unsuitable for road use - they crease up at the front, level with the pubis, and irritate the skin. Forget about the 'second skin' feeling - you will KNOW you are wearing these. Again, I don't race. If anything, I ride quite upright by road standards. The seams started to come apart within the first few uses - the outer ones in flatlock triples, so cosmetic, really, but it's only a matter of time others will start coming apart too, by the looks of it. THE WORST: the pad started delaminating - the fabric covering the gel started to come off. Now it creases up under the bum while riding, and you can imagine; it's like wearing underpants under the bibs. I ended up with a massive irritation on the last tour - luckily enough I brought a spare with me, of a different make. it would have ruined it. I have no choice but to return them - they are unusable, and it's likely it'll only get worse. The first badly designed and badly made Decathlon product I've ever had to deal with.

Excellent quality, but get size up.

These cycling shorts are definitely worth the price! The padding is excellent and fits nicely where it should. The material wicks sweat well and is very breathable. I've completed numerous rides and centuries in them and they have performed very well. Only issue I had is sizing. I'm a UK medium for most shorts and also according to the size guide however found that the medium was quite tight. The large proved just right and I've had no issues since.

Size information

Just a quick note - I haven't used them yet but I had to return to the store (bought via click and collect during the COVID 19 crisis) to change the size. I'm a medium according to the size guide, but I couldn't even get them past my knees. I swapped them for XL. If you're a skinny guy who normally uses medium, get a large. If you're like me, say 10lbs overweight and normally get a medium, get XL.

Great Value Bib Shorts

I'd love to spend £150+ on bib shorts, but then I'd spend all my time worrying that if had an "off" I'd destroy them! So I bought these instead, I have no idea if they are as good as more expensive bib shorts, but the more expensive ones would have to be REALLY good to be better than these. I have lots of bib shorts, some cheaper, some dearer, but these are the ones that I prefer to wear. They are comfortable and have a nice pad and they don't ride up your leg. Sizing was good, as I have found with most Decathlon kit and I would say they were good value for the money.

High quality but very tight!

Great pair of bib shorts (also highly recommended by Cycling Plus). Good chamois pad, well made, high quality, etc. Only down side is that they come much smaller/tighter compared against other providers. I have bib shorts from a variety of brands and have always been a UK Small. However, I twice had to return these for the next size up and have settled with a large pair. Great shorts, but buy two sizes larger than you normally would!

Triban 500 bib shorts

Purchased these five months ago. Find them to be comfortable with nice padding. Use on rides up to 60 miles. Various sized pockets with small zip pocket large enough for iPhone XR. My only issue is a hole has appeared on the lower back for some reason. Hope it’s a one off as it would work out expensive buying a new pair twice a year. I had read good reviews in the BTwin range and I am surprised this has happened. Hopefully no more will appear Would have given a 5* if no hole in fabric
