Does the type of road bike matter with how fast you go?
I have a Bottecchia road bike that I bought last year over the internet. I am not in great shape(195lbs) but I am not that out of shape either but i see other riders that look a lot more out of shape, yet they seem to go a lot faster than me.
I did a 20 mile ride and my average speed at the end of the ride was 13.9mph with rolling hills. Is that to slow? Also i forgot to mention that I have stage 4 kidney disease.
