How tall are they? (Axle-Crown). (Fox/RS 160mm forks are 545mm, Magura are 540mm for eg)
(I'm of the understanding) the leverage of the length of the fork has more to do with ripping headtubes off than (stated) fork travel?*
I seem to recall Cotic Soul mkI's being limited to forks of upto 130mm travel and specifically upto axle-crown heights of 508mm (RS RVL)
*I'm not sure on any of this though, so don't go quoting me or anything
this website[/url] would suggest 2005 170mm 66's have an axle-crown height of 595mm (2006 being 555mm), so 50mm taller than a typical 160mm fork?
