interesting thread. I'm convincec your speed is your speed regardless of your bike unless you make a jump from MTB to road bike. but once you are in road bikes, your speed is your speed. you can put that chevy 350 in a lamborgini but it's still gonn abe a chevy 350. I'm seeing some minor improvements with my new bike, but in fact they are still significant. a fabulous test would be to see my vareage on a MUP, liek a time trial on a fast course. start the computer when I start the ride not when I walk it from my car, and stop it and the end of the course. sure there will be hills and traffic situations but it's the best comparison I will have from the last bike to the new bike. I'll have to dig up my stats from last year but I have them kicking around the forum somewhere. from what I've heard if you want to go fast you have to be in a paceline. also us old guys, (just turned 53), just keep getting older. to reverse the affects of aging is very difficult, and then when you do, you kinda max out and start declining in performance again. I had a 5 yr stretch where I had contact improvements and then my age started to show in my stats again. now if you're 17 and working on imprioving your speed, well, then my friend you've got a shot at it. us? not so much. that's my opinion. am I still gonna try to see 40 mph again, oh yeah. am I still gonna try to see something over 33 oh yeah, over mid 20s or 27 on a sprint? oh yeah. sometimes though that dam computer is just a curse.
