This was a gift for my husband who is an avid bicyclist. He has two bikes and I could see him rotating his toptube bag back and forth between bikes. I tried to replicate the one he has but it seemed to no longer be available so I shopped and shopped for just the right one and he is very happy with this Mag Tank. It is just the right size to hold his phone and few other necessary biking items. It stays put and does not interfere with his knees which seems to be a problem with some of the bags. Easy open and close while biking. Good bag!
Bag is mounted on my Trek Remedy 9.8. Perfect size to carry my cell phone, a few tools, and energy bar. The magnet buckle secures the pouch's content and contents are easily accessible. Bag is well constructed. I highly recommend this product.
