It will be good to be back. Will try not to break the bike this time

New Year's resolution; build a rocker plate...
Dave I took heed of your tale of woe and decided to look into a rocker plate myself. I looked to YouTube for inspiration and came across a variety of designs from the ones using bearing blocks and tennis balls to ones using just tennis balls. As I had neither the bearings or the, err, other things I tried to construct one with what I had to hand.
I settled on using an old 26" MTB tyre and inner tube for the springs, a plastic pipe for the pivot (that was left over from plumbing in a washing machine) and some bits of gash laminate flooring for the top plate. I decided I didn't need a bottom plate as I could use the floor.
The trainer was secured to the base using cable ties.
I tried the set up on the Degollada de La Aldea (North side) and blow me it worked!
However I noticed that the trainer moved forward against the tyre when out of the saddle under high(ish) power. So after the ride I did the following mod
Secured the pivot in place with cable ties and also the tyre but this area may need some rework. Finally to save hassle in the future I cut a small hole in the tyre and pushed the valve through, so the valve is now on the outside enabling me to inflate without having to remove the trainer.
OK it's no Rolls Royce of a job but it does the trick. Hope it serves as a bit of inspiration while we all struggle to work off all those mince pies.
