The ones I made I have are mounted forward as well as down, so although 2" longer don't drop the footrest that much but do provide much less knee bend.
I can't take any credit for my lower footrests. I am indebted to Chris Launders, who passed on to me a set he had made for his bike when he was using a different frame configuration. As he mentioned in his post above, he made the arms from kickstart levers.I can tell you are someone who approaches a problem with a solution and it seems to work for you albeit the footrest pivoting forward and even then you have worked out a solution. If push comes to shove and I am unable to get sufficient bend to get at least three quarters of the way down the seat without being in pain I will have to resort to longer hangers - any idea if any supplier stocks them? The fact you had to make your own suggests not.
Hi Chris,Perhaps the folding Comet ones will fit, I understand Comet ones are longer, though spacer pieces may need to be made to get the correct clearance.
