It seems crazy that big tires and an extra inch of travel raised my BB a full inch! Wow.
I was bummed about it, but then I had a great ride yesterday on the ML- A good friend & riding buddy of ours got married saturday, so we all opted for an easy day of shuttling- we did a great local XC descent twice, dropping about 6000' total on technical XC trails. The motolite did great, I was very happy with it. Another bonus is that my AM SL is finally broken in, suddenly it feels totally coil like! except it's much lighter and has better resistance to big hits.
Well, the thing that got me thinking about BB height originally was looking at the preliminary El Guapo numbers. Based on what has been said so far, I could swap all my parts directly over from my motolight, gain 20mm of travel, yet my BB would actually drop 3/4".
Another way to look at it- if you run the forks Titus suggests, the motolite and El Guapo will have the same BB height, about 13.75". Pretty typical for a 130mm travel bike but kind of low for a 160mm bike, imho. Low being good, for XC use- not so hot for super-techy east coast type stuff with fallen trees and ledgy rocks.
