Aerodynamics can be funny. Complex interaction of alot of stuff.

Surprisingly, a waterbottle can reduce aerodynamic drag https://www.profile-design.com/road_t...r_bottles.html

TT and tri bikes are aero because...... you do them ALONE. The benefits of aero outweigh the extra weight when you are fighting air drag by yourself. If you ride/race with other people the aero package is not worth carrying around since you are dividing the same amount of air resistance with others. That's all there is to it.

Weight is ~200g difference, both are extremely strong frames. Aero has real advantages, but my Soloist is a handful in crosswinds while riding Solo. The R3 is substantially less expensive.

my experience with x-winds is like a normal geometry bike with zipp 404's. Suddenly you notice that winds do have an effect on steering. But no, I don't find it slowing me down personally. DocRay?

If the bike is being pushed sideways, it has to be slowing down. We need to see windtunnel data with air flow at different angles to the bike to know if it significantly slows the bike, but I've never seen this done.

Many CSC riders used the aluminum soloist last season if they planned a solo attack. It's still Voigt's favorite frame.

when it comes to making a bike fast, weight is mostly bollocks, compared to aerodynamics and rigidity, unless we're talking about climbimg BIG mountains.
Check out some of the weights of the bikes at the recent World Track Championships -- and these are TRACK bikes, with no cassettes, brakes, etc.
Damian Zielinski's Isaac.............16.3 lbs
Clara Sanchez' Look...................17 lb
Roberto Chiappa's Pinarello.......17.3 lb
Maximilian Levy's FES.................17.4 lb
Theo Bos' Koga/BT.....................17.5 lb
Dutch team pursuit Koga/BT.......17.8 lb
Stefan Nimke's FES.....................17.9 lb
Tuen Mulder's Koga/BT...............18.5 lb
Dutch team pursuit Koga/BT.......19.2 lb
Dutch team pursuit Koga/BT.......19.4 lb
Dutch team pursuit Koga/BT.......20.7 lb
