The Fenix and 935 are the same exact software. The only difference is a metal case with glass or sapphire lens (Fenix) vs plastic case and plastic lens (935). The choice between those two (to me) comes down to whether you want a watch to wear all day long (Fenix) or just a swim/bike/run watch (935). That said, I don't really like either as a bike computer. I'm using a Edge 1030 for the bike with my Vector 3's. Before that I had an Edge 810. I'd take any of the Edge computers as a bike-specific computer simply because of the bigger screen with more data fields.

agree with the cat... Egde 1030.
