Yeah, I’ve had a few. With a few hundred miles on the new trike, it’s becoming clear that I and the ICE design team have made some poor choices. Nothing too serious, but annoying nonetheless.

Trike Build Phases II and III: Dynamo Lighting, Hydraulic Brakes, and Schlumpf
The project is finally complete and I’m riding a new trike that satisfies many of my original goals. In the end it didn’t make much sense to delay installing the Schlumpf so I combined phases II and III. Details following.
Schlumpf vs Di2
As I spool this project back up, there is just one question nagging me: Is Schlumpf the right choice? Reality has modified many of my initial aspirations, I think it’s worth reconsidering a Di2 front derailleur instead.
A Year of Di2
A year ago today I began running Shimano Di2 electric shift on my recumbent trike. I’m pleased to report it has exceeded my wildest expectations. But like most aspects of this now multi-year project, there were problems in the beginning.
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. Continue reading
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.
True to its word, Shimano resolved the issues with my Alfine-11 hub in 3-5 days. Yesterday I received an entirely different hub by return mail. I suppose it’s possible that this is a refurbished hub but by all outward appearances it’s brand new. By most any measure, Shimano’s response was beyond reproach. So why am I not smiling?
A Step Backward
According to the postal service my Alfine hub has been received by Shimano. According to Shimano they’ll look at it within three to five days. So I should have some sort of resolution soon. Meanwhile I’m back using my old drivetrain, and it sucks.
The Trouble with Alfine
My precious Alfine hub will soon be at peace with its maker, but I’ve still got some healing to do. My experience with Alfine has been a roller coaster ride that has left me wary of internally geared hubs. Not to mention anxious, moody, and prone to sudden outbursts of sobbing. Combined with my DualDrive and Sturmey-Archer experience I guess you could say that I’m thrice bitten… fourfold shy? I’ve lost count. What follows is my therapy.
Di2 Battery Life
I’ve now got enough data on Alfine Di2 to jump to some conclusions about Di2 battery life in general. Some of what follows is still conjecture, hence the jump, but seems reasonable based on the data I’ve got so far. Update: Click here to cut to the chase; a running report of my real-world battery life since January 2015.
