I’m currently using my 301 Mk10 with 170mm forks (Marzocchi 55 RC3 Ti) and the 160mm rockers. I’m in the process of building up another Mk10 to take to Greece, (probably next year now, unfortunately) – at the minute that has 140mm rockers and I’m going to use another set of 170mm Marzocchis on that too.
So, when it’s up and running I’ll be able to do a back-to-back test and see which I prefer. I’m under no illusion that I need 170mm of fork travel, but they are beautiful forks, so……
I don’t mind the BB height, to be honest, but then I’m not railing swoopy, bermed turns very often (never, even) – more just picking my way through rocky riverbeds and down narrow, rutted tracks. With the highish BB and a 26T chainring you can roll pretty big rock steps……
