Review on 🚴 Serfas Speed Bag: Enhance Your Cycling Speed with this Sleek Accessory by Paul Barnes

This bike bag is sized to carry a bike multi-tool, some tire levers, a spare inner tube (700x28c) and a few other small items. (cash, ID card, key). I like the little organizational dots in it. Each side has elastic straps to keep things handy if you don't want them to get tangled. The zippered flap has a mesh pocket and an elastic pocket that I use for spare batteries for my taillight. Speaking of which, there is a loop for said tail light on the outside of the rear zip flap. The rest of the outside is a bit reflective and attractive enough to make the bike safer (well, I have orange). Installation is easy. I switched it to other bikes once or twice. Finally, a zip at the bottom opens up the device in case you need to take something extra with you. I think that makes enough room for some granola bars or something. I've only expanded it once to add a few extra tools while still picking up a new bike.
