    After seeing the electronic shift mechanism at a Trek store, I thought having autoshift based on cadence would be nice to have. I was wondering if this could be accomplished using an existing bicycle computer for the cadence monitoring. Oh, that’s right; it would not contain the parameters and algorithims for the shift instructions. I just found this site and will keep an eye on your progress. Thanks
