Bike upgrade! Jumped from aluminum 105 to Ultegra Di2, but power gains came from the new bottles for sure.

It’s a Cube Agree C:62. Bought it barely used with a 400 km mileage for a nice 40% discount. Just got lucky. Got a Garmin 830 as a gift too. I swapped the tires to my 5000GP 28 mm, changed the seat to the Prologo that I had, bought some lighter Elite bottles.
