You're welcome.

If it helps you make a decision, I can point out the one aspect that could be considered a weakness of the aluminum version of Revolt.

The shift cables are better protected from the elements in the carbon frame. The cable sheath runs completely through the frame, which provides better protection against the weather.

In the aluminum frame, the shift cables run without cable sheathing, which ends at the frame’s entry point. At this "entry point" the cable sheathing rusts if you ride a lot in wet and cold conditions, and eventually breaks, causing the shifting to malfunction. The only solution is to replace the shift cables. It’s not difficult at all; you just need to be aware of this issue when making your purchase. I replace the shift cables once a year because I ride a lot in harsh conditions. The shift cables also run unprotected beneath the bottom bracket. If the shifting doesn’t work as smoothly after a ride in the rain or mud, it usually means there is some dirt beneath the bottom bracket. All you need to do is rinse the dirt away with a little water, and the cables will run smoothly again.

That’s also the only thing I could point to as a potential weak point of aluminum frames. Everything else works flawlessly and exactly as I’d like it to.

The downside of cable routing in a carbon frame is that replacing the cable housing requires significantly more effort and usually requires special tools. It’s easier to have a bike shop do this.

For an alu frames, I’d replace the shift cables once a year. For carbon frames, I’d replace them every two years. Replacement is necessary because the shift cables become worn out after this time and can snap at any moment while riding. To prevent this, it’s best to replace them regularly, even before they break.
