Trike Build Phase I: Ultegra Di2

At long last, I’m riding a complete installation that meets at least a portion of my original goals.  It’s been a rocky journey but now I can tick off “fast, precise, and reliable shifting that is impervious to freezing” and “high quality, ergonomic shifter” from my list.  Here are the gory details of the recent build that got me here.  Once I’ve had time for evaluation and to refill my coffers, I’ll embark on Phase II—Dynamo Lighting and Hydraulic Brakes and Phase III—Schlumpf.  Stay tuned.

Plan B

Contrary to my previous post, I am actually relieved to be dumping the Alfine.  Who knows if I’ll ever wind up selling the thing—there seems to be a glut of under-priced (gray market?) hubs out there–  but at least I now have a high confidence path forward.  Here is that path, with very few question marks remaining.

Door #2

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.
