Both look to be running about 32/20, which is about 45" on a niner. Not many people go much over 2:1 on 26" XC bikes, which is about 53", unless they're on consistently flat terrain. I run 27/13 on my 26" bike, but that's for river bank rides. At Swinley, 27/15 would be better for playing.

I always ran 34x16 on my 26er, 34x18 on my 29er, and 32x20 on my Pugsley...and i lived in Scotland and rode the 7 Stanes red routes on those gears...a lot of people seem to run gears smaller than necessary on single speed mtb's in my opinion.
