Is a Bike Fitter Enough?

Got a new bike and Richard Baxter has left the country. Replicated the same measurements he did on my old bike and although I don't have any pain,  I'm very uncomfortable on the saddle. I have the right width seat for my sit bones. Sliding all around especially on the trainer. Could it be an old seat or do I have to go to a fitter?

Compare the frame geometries.. unless the geometries are the same the setup will be different and uncomfortable..

As stated by Mike if the geomtries of the bikes are different your fit won't be a plug and play. Also it's important to try and pinpoint the nature of your sliding around. Are you constantly moving yourself back or forward on the saddle. Both can be addressed with adjustments to your saddle setback and or saddle tilt.

Reach
Handledrop
Frame reach 
Etc etc all can contribute to this

The sliding around is likely compensation for some other unintended change in the bike set up. Could be anything and everything listed above include stance width (Q-Factor of crank - I assume you moved your pedals and shoes across from previous bike)

Like a slippery seat. Lay off the Mr Min maybe?

Yeah, totally different geometry. Coming from a 2016 Merida to a 2021 Scott.

Yes, it's basically trying to find a comfortable spot. No issues on joints or reach etc. It's more noticeable indoor since I'm stationary. Makes it very difficult to exercise in the week. Arranging to go to someone soon

I did slam my stem so could be this. I was using AI tools and a tripod to get me going and I came 80% close to perfect..

Lol... actually the seat i have is old and although the correct width, could be the reason for all the sliding. No Mr min though

Actually didn't and the cranks are shorter...hmm. sounds like you answered my reason to go to a pro. Thanks

sound like you made way too many changes and now you have no baseline anylonger. Time to se a pro

Agree here.. 

too many changes are going to hurt you.. 

I compared geometries and bought a carbon bike that’s geometry was so similar we set the new bike up almost identically as my previous bike.. it actually ended up shortening my reach a bit.. so that was a win but now only 6 months later I am tweaking that position eve so slightly.. dropped my stem down a space and put my saddle up 3mm(felt like my heel was dropping through the bottom of my pedal stroke, and a little tilt to give my junk some more relief.. will ride like this till the end of the year with no further adjustments.. unless it causes harm somehow 🤷🏼‍♂️🤣

Try Mitch at Mellow Velo. He did a fit for someone I know and they were quite happy. He also gave me some great advise with some of my tweaks at no cost. And he is a pretty decent dude as well.
