I still use a Cateye Tomo. The good thing is that the wiring kits are so cheap and available that I've now got about 10 kits, so I can switch the same "speedo"* from bike to bike.

by the way, I hope you all did the geeky thing like me and bought a new speedo battery and reset it on new year's eve



* I'm gunna start calling it a "speedo" and change the trend right here, right now, so, in 10 years time when everyone calls them a 'speedo', we'll know it started right HERE!
