I've used this bracket to keep both my TiGr bike bow lock and its cylinder in place on my top tube during my commute.
This makes it much easier to stow the lock, and it does not move around.
The bracket fits a 1 1/8" diameter top tube.
To install:
- Feed the cinch straps through the slot in the middle of the bracket.
- Cut a 2"x3" piece of bike inner tube. This will protect your finish and help keep the bracket in place.
- Fit the square of inner tube rubber into the bottom part of the bracket and press it onto the top tube.
- Pass the end of the cinch strap through its D-ring, and you're ready to go!
