Brake jack is not that noticeable at all, my previous Marins were far worse IME…..nail on the head there Jambo 😀
As for over-priced…thats rich coming from someone who bought one Hora! Frame only it's about equal to a Santa Cruz Heckler which is far east manufactured in (possibly) larger quantities. Anyway, I loved the 2 Fives i owned and i do believe thats about as good as a single pivot gets.
However, a linkage activated single pivot like my wifes 575 or the horst link (i think) Zesty i now own are that bit better and in the case of my Zesty, has no pedal bob in any gear where as my 5's were both awful in the granny ring and did need constant use of the propedal lever!
I found the new geometery on the 5's that fraction too slack and i rarely found myself using it on local more twisty singletrack but i find the Zesty is great on everything i have ridden so far.
