Good that you feel more confident - but I'd be surprised if you found any difference in performance, as opposed to comfort, especially as you've fitted much heavier tyres. The Contis + Schwalbe tubes are well over over twice the weight of the original Hutchinsons, according to website info. BTW the wheels and OEM tyres on your D30 are definitely not the 2018 spec, which was Airline Corsa with 28mm Kenda Krampfish (!) (450gm) + Kenda tubes (110gm), with a QR front spindle. (The 28mm Conti GP4000lls' I fitted are 250gm each, your
37mm Conti Plus City are 850gm).
I suppose it would have been easy enough for Orbea to change the wheels to the newer spec. Are there any other differences in the spec you've noticed?
