Polar CS100 HR monitor and speed meter... another boring investment. BUT I got dibs on a teammate's Fizik Arione for cheeeeap. My training should be pretty much optimized now that I (FINALLY) have some data reading and my taint won't hurt after 20 minutes in the saddle.

edit: Sorry for all the roadie banter... I don't think I'll ever make the transition to the road forum...
