Yes I was surprised by the magnitude of those numbers too even considering the source. That said, I have a “funduro” bike with 137/160 and to me it is just more fun than my XC bike. Unless I’m wanting to go fast I grab the big bike. Even on days I want to go hard, the heavier longer travel bike is just as easy to go hard on as the XC bike and going down it’s just a lot more fun.
I am sure others will have a take but that’s my quick $.02.
