My main commuters I have them (cateye strada with cadence wired) but I find them being less and less important. One of those bikes was supose to sell and it got pulled off. Deal fell through and not sure I am going to bother putting it back on. I do like the cadence and I loosely keep track of my commuting miles and miles on the parts on the bike. Clock is bad about accuracy so I have to reset it every few weeks and even got lazy about that. The second one may end up on the Trainer (Trek Mtn on a Advocet trainer). I have no plans to add them to any of my other bikes that I like it keep understated.
