Not trying to hijack thread, but the thing I like is that we all can have an intelligent conversation and relate our experiences with a bike we all love. The f6B in my opinion is the best bike I have ever owned but given everything that I like about it, The suspension for me falls short of what I would like it to be, nothing more than that. Looking at prices for traxxion upgrade will be roughly $3K to $3.5K. For me IF I do this upgrade I will still be far short of the money it would cost to buy a new one, that is because I bought my 13 used.
