Kudos to you and to Trek. I will view them in a different light after hearing this.
Here are my two questions:
1. If ever there were an application for a single control-point shift mechanism, this is it. IOW, from the one control point you decide to shift up or down, and the computer decides whether to move the FD, RD, or both. Did that idea ever come up in your discussions?
2. Concerning braking, how do you deal with the issue of forward pressure on the right handlebar side?
Thanks,
Al
