It says on the new Soul that the geometry is unchanged, sounds a bit geeky i know but wasn't it 71ha 74sa before ?? now 70ha 73sa
Just pulled this out a of recent email from Cy:
"The original 71/74 was based on 470mm forks
sagged 30mm giving 440mm a-c. Most 100mm forks are between 475 and
480mm these days, and because everything's got so linear in the air
springs, I've not used more than 25mm sag for years, which gives
around 450mm a-c and 70/73."
Oh, and previous versions of the Soul were designed to handle well with 100-130mm forks (been running SC Dorados on mine for a few years) not just 100mm, so the new 100-140mm range works fine handling wise, Thors are a good pairing for big hill riding. Worth noting that the it's not just stronger for 140mm forks, there's a few things going on to make it stiffer in the directions need with bigger forks, such as that Ovalform top tube. All still works with 100mm forks though if need be, and it's not gone heavy, don't worry…
