    I have used this bag for a couple years now, and it satisfies all my needs in a bag. Small when riding light, expandable when more storage needed. Like getting two different sized bags in one! Great looking too.

    Just got this today, and I couldn’t have had a better ride. I was able to fit minor emergency gear, cell phone, money, and keys with plenty of space left over. It’s lightweight and expandable making it ideal for everyday rides. I wouldn’t recommend it for multiday trips due to the size, but it’s very convenient and surprisingly quiet even on bumpy roads.

    The perfect saddle bag! The Speed Bag is perfect for rides when I want to ride light without a pack. It holds everything from keys, cell phone, tube, tools, etc. The expandable feature is like having two bags at your fingertips. The Speed Bag also has a key fob and internal pockets. There is a light mount, reflective trim, and the velcro system ensure a snug fit to your saddle. There are bunch of great colors to choose from too!

    Simply the most versatile speed bag on the market. Check out the inside before considering another bag. Reflective on sides and back to safety, 2 types of tail light mounts, expansion allows even a full bag to add a large bike-weight jacket. Perfect on the inside to hold keys, cards, lip balm separately. Different colors available. You can buy a cheaper bag, but not a better one! I have these on all of my bikes.

    Just purchased one of these bags from my LBS. Hanging on the wall it looked like it might be a bit big for my needs. Turns out it is perfect size for what I needed to pack into it: two 700c × 35 inner tubes, a set of tire levers, and a CO2 inflator with two 16G cartridges. I also appreciate the fastening system-the ergonomics of installing and removing were obviously a consideration in the design.
