Thanks for the recs, looks like the Topeak bags are pretty solid.
uekiya, how much are you able to fit in the Pro Pack (Small)? Ideally I’d like to fit a tube and mini tool and maybe even my Topeak Race Rocket mini pump (it’s small).
trek7k, I was recently looking for a seat bag / mini pump combination that would allow the pump to fit inside the bag. In the end, I bought a Topeak Aero Wedge (medium) & a Lezyne HV Drive. The Race Rocket was in my consideration too, but the Lezyne was available & cheaper at my LBS.
The HV fitted snugly in the bag with 1×26" tube, mini tool, levers & key pouch. Though it touches the zip line, I was able to zip up easily without stretching the zip. This is without expanding the bag via its additional zipper yet 😃
So yeah, the Race Rocket should have no problem fitting in.
