Putting a 170mm fork on a max 160mm frame
I have a 2009 Yeti 575 that I bought used and it currently has a 130mm Fox float RLC on it. The bike comes stock with 140mm for the low end build and 160mm for the high end build I believe. Either way, the max fork travel length as specified by Yeti is 160mm.
I wanted to stick a 160mm fork on my bike I'm having a really hard time finding a 160mm fork for this bike without buying brand new which I can't afford. This is mostly because it needs 1 1/8" steerer tube.
I found a good deal on a 2012 Rockshox Lyrik 170mm which I'm wondering if I can use or if it's a bad idea. At first I wasn't even thinking about doing it but then read something about how it's the axle to crown measurement that really matters and not so much the travel. From what I'm able to tell, the Lyrik has the same axle to crown measurement of 545mm as a 160mm Fox Float.
Does that mean I would have the same geometry change as if I put a 160mm Fox float on it?
I actually like the idea of 170mm travel as my local trails (Whistler/Squamish/North Shore) get pretty rough going down.
EDIT: Just realized I read the specs for the 160mm Lyrik and the 170mm has an axle to crown length of 555mm :( Is it still doable?
