I have this great idea, but seems like nobody has ever tought of it. How COOL it would be to put Analog Tachometer on your bicycle 
I am sure that I make 100 REVs per minute (or more) and it would be very great to know at how many revs you shift your gears when racing. Me and my friends are drag racing with our bikes and shift points are crucial to wining the race, too bad nobody has made such an device. And if you know something like this you can tell me. I think I saw some digital ones but I am not sure AND they're not good...What do you think?
