Have been using this bag for about a month on my mountain bike. Used 4x a week. Holds 1 innertube and small alen wrench (not the whole set) OR a small cell phone and keys. The quality is good but I wish I had bought the medium sized bag instead for short trips. Read the dimensions and make sure this small of a bag will be the best fit for your needs as this one is REALLY small.Get more detail about M-Wave Bicycle Saddle Bag (Small).
