^^^

Your post is a long winded way of claiming that none of this matters because humans are marvelous creatures that can compensate for a bike's deficiencies. I agree about the "marvelous" part, but it...

A lot of training is just "grinding wheat". No need to get all serious about it. Just gotta grind the wheat so you can make the bread. I think data driven training has really zapped the...

I agree. Track and road are different environments. And it could be that variables that are significant on the track do not have the same significance when on the road.

You should move that roller back a hole (maybe two; hard to tell from the angle of your photo); it will be more stable. Try it before you protest. I've done a lot of roller miles. The front roller is...
