Fits okay Worried about the string mechanism and how it is to replace in case it brakes.
I got this bag for my MTB specifically because it can hold a giant tube for 2.5 tires--which it does quite easily, with plenty of room left for a 25g co2 cylinder, inflator, and tools. I also wanted this bag because it's set back a little, which allows the dropper post full range of action.
Bag holds CO2 inflator, two extra CO2s, Topeak multi-tool, dynaplug kit, tiny knife and a small tube of Tufo sealant - comfortably too, I am able to zip it all up without fear of busting the zipper. BOA holds perfectly - the bag never sways or comes in contact with your thighs. Bought on clearance for $36 I believe - it's a steal. Really well made.
