Excellent small bag- Fits all you need for a road bike. Strap is long enough to fit an aero post on my Dogma!
This is a spacious, good quality seat bag, which unfortunately did not work on my aero seat post and rear light arrangement.
Easily holds one or even two tubes and tools along with room for a wallet or smaller phone. Expansion option is cool for other items too!
Well made bags that I have on all my bikes!!!
Nicely made, but the way the zipper has to fully cross under the seat is a bit awkward.
