Suspension on fat tires feels like more travel than it really is. My Lefty is limited to 70mm, and it feels like my skinny tire Trek Fuel with 120mm fork.It will change your head tube angle by about 1deg and raise your bb a tad. I'm thinking 80mm plus fat is going to be enough for where I ride, I hope.
I'm at 510mm A-C on a 110mm lefty. Built it up this way from the get go and never tried the stock fork. It's a bike, it rides just fine. Don't over think it.Thoughts on how running 100mm on a 2013 mukluk would affect the geometry? I'd imagine those who've thrown a lefty would have some idea on how it changed the handling. I really want to ride this on some dirt but I don't know if I should do it for only 80mm of travel. Thoughts?
