Huge (125 cu in / 2L) capacity keeps snacks, phone or extra clothing handy. The bag secures to stem and top tube with hook and loop closure. Bowling bag vibe. Would have been the preferred cycling top tube bag of Big Ernie McCracken
Zippered main compartment and side pocket.
Cut-to-length frame straps fit nearly any frame size.
On narrow tubing you can make a shim, attach it to the tube to make it thicker to help with attachment or you can wrap the straps 2x around the tubing and secure.
Rigid bottom and padded sides to hold shape
Maximum dimensions: 8"L x 6"H x 4.5"W
Hey Skippy- Bag has soft fabric straps, but continuous use can scuff bicycle's paint. Clean frame contact areas frequently and protect contact areas with tape for prolonged use.
