Rat Bikes! Pub Bikes Beaters! Frankenbikes!

Any tips for getting a bottle cage mount like that ^ to behave itself? I've got one of my Donohue and it's still wobbly even with a couple of beefy cable ties.

That was solid, need to put it back on soon for the summer!

bit of that pvc tape, one of those rubber shims you get with some lights and jubilee clips, cost me 80p for 2 of them.
