Ok, I really hope this is not a stupid question but during TR podcasts and others like Flo etc they always reference a xW gain based on a change.
Example would be using a certain tyre would give you 10 extra watts (made up example but it makes my point)
Question is, what does this actually mean when I am on the road riding my bike? I don’t think I up my FTP by said 10w as this doesn’t sound right to me, I assume it is just a way to measure effieciecies gained between choices and the benefits vary depending on the rider, terrain etc
Thanks in advance
