Road Test

I’m still waiting on my order for 166mm spokes so that I can rebuild the Alfine wheel as a cross-2 to address the spoke angle problems of my original cross-3 build.  Apparently spokes this short are pretty hard to come by but Cambria Bicycle Outfitter assures me I’ll have them in about a week.  Meanwhile the weather has dipped into the teens again and I’ve been stuck in a single gear for my work commute.  Last night I’d had enough and decided to throw what I have on the trike and see how it works.
