This thread has aroused my curiosity about TPU's.
Some of the splurb about TPU's are saying significant increase in speed etc. what does "significant" really mean, say over a 10 mile time trial@ 20mph?

I wish.
I only ever beat 25mph once, for a 10 and that was in 1969. Probably won't next season either.

Mine was more recent but still over 40 years ago.
