I think the Tririg stem or the pro missile evo stem would probably achieve what you're attempting to do

To be more specific, that is a Scott Plasma4 10. It doesn’t have an integrated stem because an integrated stem is not very accessible.

If you are interested in aerodynamic improvements, you really need a bike fit. That setup has a number of symptoms that suggest it’s pretty poor (armpad level and seat choice being the obvious ones).

The steer tube diameter may or may not be different

Plasma 3 has a 1-inch steer tube. Not sure what yours has. At least according to R&A, the Plasma 4 10 has a 1 1/8-inch

 A stem is not the answer to your aerodynamic desires. Start with a fit as suggested by Trent.

I have a update to my stem that will definitely clean up your bike.

Will first make cnc sample to check safety, etc, then will post for pre orders when we confirm unit pricing, etc.

But likely will only offer 100mm in the beginning.

This was about what i wanted to react but saw your post. So completely true. Anything as an aerodynamic upgrade other then doing a fitsession with a good fitter will be a waste of money
