Should one get a new fit or just adapt?

That doesn't say much! Does it mean you have a much larger drop from saddle to bar?
Why not just ride it and if it doesn't feel good, try 2mm spacer in increments untill it feels right?

The body can adapt but there is a point where you need to be in your best shape to make it work. I'm not always in my best shape and I don't race often so I'd rather keep it a bit higher for training.

Also there is a point where your power output loss is greater than the aero gain. No need to pass that point.

Also how long do you need to hold an aero configuration? A 10min time trial is a different beast compared to a 6h race.

How low can you go? :D

I would say everyone should slam but not cut and go up until they find the position comfortable enough for over six hour rides. Just like when you tune a guitar you tune up from flat not down from sharp. Being too high up and not be lower is just a waste of potential aero. However I think it's rider choice if you want to be comfortable in the drops all day or be comfortable on the hoods all day. I ride on my own and like riding for hours in the drops becuase I don't have other riders to sit behind. Also you can lose watts being too low, so everything depends on your bike geo, your body type and your riding/race style. Seems like climbing/descending bikes can be the most slammed as you usually climb on the hoods and descend at relatively low wattage. A crit bike would need to be low enough for good aero, but not too low that you lose wattage when sprinting on the drops. Also some all rounder bikes have pretty long head tubes and other more climbing specific are way shorter.

Most bikes I see look too high with loads of spacers and a very unaggressive stem angle or postive stem, and they look very noobish just becuase most bikes are sold like that and most people never change their setup out of the shop. On the other hand there's no point in copying a pro postion if it hurts you.

^ definately do not cut until you have had multiple long rides... hardly anyone I know stays in the drops all day unless you are racing, but on the hoods/aero arms is just as good or better. (except you cant bump people..again racing)

Hopefully the fit included an explanation on why you ended up in the final position. If not, go ask your money back. If it did but you didn't listen, go get a refreshal on the most important piece of the process.

After riding for 6 years with my stem spaced at whatever the shop gave
me. 3cm? Or more. I slammed my new bike then went back and slammed my old bike. I don’t know what I was ever thinking having spacers. I just didn’t know.

I didn’t notice any difference in comfort. It possibly even helped my back and the aero factor is, I feel, very significant.

Depends what you mean by "bike fit".
If done by a professional, the best fitters IMO are also physio or sports therapists, kinesiologists, etc. They first of all make a physical evaluation first.
Then they install you on your bike with the best fit possible considering your limits.
If the competent bike fitter put 10-15mm of spacers on your bike, it's generally because you won't be better with a lower cockpit.
If it's a bike shop fit, then do whatever you feel is right ;) .

This obviously is no help, but shouldn't you have communicated this with your fitter? Specially since you paid money for it?

Not that much.

@jugi,

It's a used frame and I didn't know it was cut so low. There's smidgen bit of space to raise. If it doesn't work out, I'll buy a new fork.

Kind of an important point to state in your original post, No?

If it's not much you could raise the handlebars and maybe use a shorter stem to compensate.
