Yes, the attachment system is designed to cinch down tightly to the saddle rails. When properly tightened, it remains stable and won't bounce around, even on technical terrain.

It is sized to hold standard cycling essentials like a spare tube, a multi-tool, tire levers, and a CO2 inflator or mini-pump. The internal layout keeps these items organized so they don't rattle against each other while you ride.
