does the job perfectly

Total :


Am currently preparing for my first half ironman distance triathlon and wanted a top tube bag to keep my food in for the bike section. Originally I bought a "Zone3 Aero Top Tube Bag" from another retailer but that was awful. It wouldn't fit securely to the bike and flopped all over the place, banging your knees as you pedalled. After returning that I decided to buy this one because of the positive reviews and the features aimed at stopping it from slipping. I was not disappointed at all when it arrived and I used it for the first time. It stays nice and secure as you ride, is easy to get into on the go and is more than big enough for the 6 or so bars and gels I plan to take on the race. As some other reviews have said though I wouldn't advise anyone to go for the smaller version. This was also part of my first order from probikekit, items arrived quickly and securely. Will be using this site again in future :)

Top bag

I got this for ironman uk and managed to fit 9 small bars in it. I didn't zip it up but they all stayed in and the bag held up well.

Excellent Bike Storage for Triathlon

Total :


This storage bag is excellent, well made. It fits nicely behind the top tube giving you easy access to gels etc while on the bike. I use it to store emergency spares such as multitools, tyre levels and spare inner tube, plus was able to fit 3 gels in there. Zip was easy to use and pocket was easy to access with one hand whilst riding your bike, with nothing falling out.

What a great little bag

Total :


Not sure why I have waited so long to get one of these? It came in really handy to keep extra gels/ powerbars in during a sportive. Sure beat the hand scratching around in the back pocket of the cycling top! The bag itself is really neat and the zip was pretty good as long as you don't stuff it full with too many things. Definitely recommend it.
