1.5mph gain is huge.

i.e at the end of an hour you'll be 1.5 miles further ahead. Or one lap ahead in cross, possibly two or three in a crit.

I was thinking that, it'd knock over a minute of my PB for a 10 mile TT. Typically you I'm looking for seconds over that distance.

Only if you are doing a time trial, I would say

Indeed. Or just riding on your tod.

'for a given amount of effort' if you are expecting either a wattage or a perceived effort to give you a certain speed then it's never that simple

road riding is all about laying down a set effort for long periods, so you need to get to get the fit sorted and then ride the bike lots more

Had a few thoughts...are you using the same pedal system between bikes? Is your saddle height the same between the two bikes (n.b. can of worms opened...different crank length = different saddle height)? Both of these things will affect your 'feel' of the bike and your sensation of power delivery to the pedal.

Like I say, just thoughts...

It boils down to this.buying things doesn't automatically make you faster.

you say you don't ride it much,ride it more.Was off the road bike for a month,had my usual ride today.
felt like shit.You can't buy your way out of it.you can ride your way out of it.
and get a fit done.

How much tangible difference and useful feedback and data does a fit generate?

Does the fact that fits are generally done by bike shops mean you end up getting advice like "see this stem and these cranks here, or that bike over there, that we need to shift stock of, you could be doing one of those..."?

well,it's a really good starting point.made a lot of difference for me.

The shop I went to wasn't like that,they charged me for the fit,I then got a stem off crc.
but it is a fairly precise starting point.you still tweak a bit.and lowered the stem as I got fitter.
Basically it saved me lot of time,hassle and frustration.

want to get a fit done at the mapei clinic over in varese,it's not that dear.bit of a hassle tho.

I've spent some time tinkering with the set up, and have lowered the bars by flipping the stem, and it has made a hell of a difference.

Previous times on commute:
01:22:57, 01:19:01, 01:21:14

New set up:
01:12:46
