wish i read the reviews before I purchased this pack.
Quick Click snapped off on 5th ride... poor design andor quality
The quick click mounting clip broke the 4th day I had the bag. It occured in the middle of a 10 day bike tour. The bag itself is nice, holds a lot of stuff and is expandable. Elastic straps on bottom will hold a micro pump securely and the tab on back is a nice mount for a rear flashing light during commutes. The bag is great the quick click clip is junk. Buy the strap version.
I ordered the small and fits alien 26 multitool, tube, credit card & ID, phone, and an energy bar. inside has a vertical seperator off to the right creating a 1 12" space. i put my tube in that space. it does come w the fixer attachment but it is made for standard seats w wide seat rail. i got the standard to barely fit my rails but definately did not fit right. i needed to purchase the topeak F22 fixer attachment for the narrower seat rails of my san marco seat. didnt even know they had that attachment until i visited the topeak website. this would probably be the reason why the fixers are breaking on some of the bikes,
The pack is well designed. The quick release clip works well but the screws supplied for attaching the clip to the seat rails were too short, I had to go and buy some longer ones so I could attach it. I purchased the small, good for two tubes, inflator, 2xtire levers, 3x CO2, patch kit, small multi-tool, car keys & beer money.
I purchased the medium bag. Perfect for a spare road tube, multi tool, tire levers, inflator, a couple CO2 cartridges and my cell phone. If expanded it has room for a wallet or energy bars as well. All was good for two weeks. Today I was on a ride and hit an unexpected pot hole. Not hard enough to do any damage to my bike or cause a flat, but something was wrong. I looked down and the bag was hanging from the seat tube strap. Upon closer inspection the rails on the plastic clip just snapped off the mounting bracket. So, I cannot recommend this bag. I will be returning it and getting the one that attaches with the velcro straps. Good bag, bad clip.......
