Thanks all for the tips on contacts.. guess I'll try for dailies since I'll probably use them infrequently (at first).

On bike computers: I like my wired VDO computer from MEC, and previously have enjoyed a Cateye -- I forget which one, but it had cadence. For clean wiring, get a front wheel sensor model (unless you need cadence or care how many km you put on the trainer), and run the cable down the front brake housing and the back of the fork.
