Like every other crosser, I constantly debate gearing choices. I've been debating the single ring thing for quite some time now but have been convinced otherwise by the guys at the shop. My problem, is my bike was designed around a mountain crank, so only a really small inner chain ring works.
I currently run a Ritchey WCS crank with a 34/50. The 34 is just to small and the 50 is to big for most courses. Basically, I end up staying in the 34 most of the time and end up spinning a whole heck of alot.
I'm not sure why I didn't think of this myself, but I was reading Brooke's blog the other day where he was discusses his gear choices and it hit me... instead of going single, why not compromise and put a smaller ring on the big side. I went and picked up a 44 today (I have a 46 & a 48 in my parts bin) so I have a variety of combos to experiment with.
I think the 34/44 is going to be a good combo. I really doubt I will need to drop into the 34 much anymore as the 44 will suffice for almost all courses.
