I'm building a new MTB, my first in 10 years. This will be an XC bike for trail riding and singletrack (no racing). The bike will be built around an older (ca. 1997) Fishlips/Titus ti hardtail frame. Frame is medium sized, and I'm 5' 8". I want a bike that climbs very well; I won't be pushing this *too* hard on the descents, as I'm now 41 w/two kids and presumably know better.
I really like everything I've heard/read about the Fox Terralogic forks and plan on using one. My question is an old one: the frame was probably built for an 80mm fork, and I wonder how sluggish it will steer and/or how much less climable it will be with a 100mm fork. I realize that for 90% of the stuff I ride the two forks will probably behave similarly, so the question is really about that final 10%: how much climbing/steering ability do I sacrifice by slacking the head angle by 1 degree, vs. how much additional descent capability do I gain with the extra 20mm of travel?
If this were your project, which size fork would you go with? I don't plan on hammering this bike down much stuff, but both forks are the same price and an extra 20mm of travel for the same price sounds tempting. At the same time, I plan on owning this bike for at least 10 years, so I want to make the best decision possible.
