I’m working on a Trek Chelsea 9 https://www.trekbikes.com/us/en_US/bikes/hybrid-bikes/chelsea-9-womens/p/16190/

I want to add stem rise for an even more upright position. I’m newer to bike mechanics/maintenance and want to be sure I’m doing it all correct. I want to knock out/drill out the star nut and swap for something like the Soma 273010 pictured here. I don’t think I’ll need the full height of this but like that it could allow for more adjustability than a shorter riser. Any tips? Thanks!
