That was what I went by, but found your spring weighs quite a lot out,
but your max weight spring before you need a revalve was spot on.
is the linkage on a bip the same as a mono as I dont understand how you got one so right but the other wrong,
it worked for me as I wanted the sping for two up, the original was fine for just me even with my 17 stone lump on it and the lighter of my two kids at 5 stone but it could not compensate so well with my elder one at 8 stone, and as for the wife well,
dont get me wrong I was and am very thankfull to you for the article at least you give some numbers that I could and did use, and I wouldn't of done it with out them so I owe a BIG THANKS.
we all should get the numbers for the weights and the bikes that have worked for us and put them on this site,
just as a starting point,
THANKS again
