I’m loving this bike! Nice and light, very responsive and quick. Comfortable for rides over 100km. The 105 di2 gears are a nice upgrade from the mechanical 105 group set. Better value than going to ultegra mechanical. 99Bikes did a great deal for me. Definitely the best price I could find and it was ready for collection within 24 hours of ordering. Best value carbon bike with 105 di2 available!
