And, now, for the Rans XStream. First, I include pictures because the X-Stream is a fine looking bike. Note the Zipp 404 wheel in front! It’s also got Q-Rings and a low-profile, aero front brake with the Shimano 105! That bag behind the seat isn’t just convenient to hold things, it also makes the bike more aerodynamic, saving about 7 watts at 24 miles per hour! I can even GET to 24 miles on hour on this bike! The seat angle is about as low as it can go on this bike, which is about thirty degrees!
