Thanks.
By the way: U.S. rubber band size number 82 will increase necessary forces nicely at least for several weeks before wearing out. I put 3 on each pedal (vertically from pedal to platform). It seems to me the force just about tripled, and increases the further you mash down the pedal, exactly as you would want. The bag I purchased for $10 or so was marked approximate 230 bands in the bag. #82 is 2-1/2" long by 1/2" wide (a very wide rubber band). They will stretch to about 3-1/2" on the pedal but you put the same number of bands on each pedal so the forces stay equal and centered, if they were before. In fact if off centered before, it might help center them.
