More Spacious than I Anticipated

According to the order sheet sent in the box, I was sent a Triban 300 saddlebag, which is the same size but has a strap to attach to the seatpost as well as the saddle rails. Fits a 700x32 tube, 3 tire levers, a small multitool and a single CO2 cartridge and inflator. Overall everything you need at typical Decathlon quality and price.

Too small

I recently got my Cycling Saddle bag, and I must admit I am slightly disappointed. I took a picture of the bag next to a 200ml can and they look they have similar size. I find difficult to believe that the 0.5L advertised volume is correct. Apart from that the product seems ok

Extremely pleased with this version

I'm extremely pleased with this version of the bag - an upgrade from the all-fabric version ealier. Purchased this because I lost the other one. Love the semi-rigidity of it. With this I can pack: 1 inner tube, 2 levers, 1 set allen key, 3 AAA batteries, 1 CO2 cartridge, 1 nozzle & 1 patch kit. Superb!

Does the job

Can fit 2 tubes and one tool. Cheap, compact and does the job

Good quality


Dinky, just enough for what I need

I never stray too far from home, so taking things like spare inner tubes and tyre levers didn't really factor into my purchasing decision. So long as I can take a multi-tool and some energy sachets. For £5 you can't really complain

Inexpensive, compact

Just about large enough to fit 1 26×1.75" spare tube, a pair of tyre levers and a small multi-tool - might possibly also get a short 14mmx15mm spanner in at a push. Also, easy to fit and easyto access - so, it fitted my needs perfectly.

Small but practical

Lightweight, discreet, water resistant & easy to fit. It sits snugly under the seat and doesn’t look like your on a bike packing adventure. I have one inner tube, tyre levers and a multi tool in there with space for two “emergency “ gels. The strap for fitting a light to is a nice feature, I have put a light on and I didn’t anticipate using initially . Bargain at less than a fiver too!

A tiny bag that holds a lot of content

This tiny bag holds my tools, spanner, foldable gym/shoe bag and leg straps. It’s cheap and cheerful, yet very useful and durable. Quality for low cost, beating the competition.
