I bought this to carry the contents of my jersey pockets on longer rides (100 mile days). I hate having heavy saggy pockets and prefer to be self sufficient on the bike to limit stops I carry a tube, mini pump, rain jacket, 3/4 cliff bars, a few gels and still have rooms to throw in my arm warmers and gloves when they get jettisoned when the temperature lifts. Install is super simple with just two straps. Whilst there is little movement in the bag I would still have preferred to see a small bungee cord to loop around the steerer tube to offer additional security. Those with out front computer mounts might find the zipper difficult to operated but I prefer to stop before fiddling with the bag so this has proved of little concern. I have swapped the bag between bikes and remove and fit it regularly when bashing the bike and so far there are no signs of stress or strain . Fantastically well put together and the side mesh pouches are great for easy access items. I tend to keep a bar and gel either side for on the go fuelling. Well worth your consideration.

The canister bag from Restrap is easy to attach & big enough for a rain jacket & some nutrition/spare tube etc without being a wind break,. Great for Autumn/Winter rides especially.
