BikerMack - I love the computer. The temp read out is a bit... so so but considering all I really care about is "is it hot" I don't use it very much (the beads/waves of sweat rolling down my back and forehead tell me its hot). Otherwise its brilliant though it does lack the simple looks of my PB Protege 8.0.
At the time I posted this, it was on my old All Pro 10-speed "road bike" which has since been retired and replaced with a 1997-8 Giant Kronos 21-speed road bike. Works like a charm on that as well, though I haven't busted my butt to see what the bike can do, I have hit 35.
Zan, I completely agree that knowing the road is a good idea, if not critical. The stretch of road that I find easiest to achieve high speeds on is a very familiar one, as its the last mile right before my house during my commute. It was recently (my guess is within the last couple of years) resurfaced so there is only a few small pot holes. Its a great feeling! There's a bigger, longer and steeper hill I fly down every day on the way to work but it is so riddled with pot holes that I'd be willing to bet the road is comprised of 80% pot holes and dodgy patch jobs and 20% original road. Its terrible, so I ride the brakes down it most days if there are any cars around, JUST in case.
