Good stuff. One comment / feature request. Given how popular the Tarmac SL8 is going to be (those performance numbers 
), it would be nice if it wasn’t one of those “paint locked” bikes. Zwift is going to be full of bright white frames everywhere. Maybe at upgrade Stage 5, allow for a color slider or offer a new colorway?
It was kind of nice that the more recent top performer (Dogma 2024) had some color options so at least there was some variation. Is there a reason the SL8 is paint locked? Some agreement with Specialized? If not, god speed on getting us some colorway options for it 
Only other request would be to maybe give some visibility to what each upgrade stage unlocks. Eventually that detail will become public knowledge through 3rd party websites or the like, but wouldn’t hurt to have that detail in-game. It would be good to know what exactly you’re working for given the significant time and effort required for each frame.
Other than that, the new power challenge and these upgrades are good stuff to keep us motivated to get on the bike and put some time and kilometers in on Zwift. Thanks!
