After feeling the nice damped response of a Brommie while test-riding some bikes last weekend, I thought perhaps I could get some real rubber to try out on the Mini.

At a local rubber shop I found a rubber doorstop which has almost the perfect shape. It has a 10mm recess at one end meant for the screw, and it has just the right diameter to completely fill the space. All I needed to do was to increase the screw hole size to 9mm. It fits almost perfectly. The recess slides just about perfectly around the boss for the original spring, and fills the space around the boss almost like it was purposely designed for it.

Anyway, I installed it last night and rode the Mini to work and it is perfect, better than the blue Cane Creek elastomer.

It could be a bit longer though, so perhaps I will get another one and combine the 2 back to back. Riding it it compresses into a bulging shape like there is a squash ball in there. The rubber concertina is not installed, not necessary.
