According to Ciro (Twitter) Moscon is the 27th QuickStep-rider! Underwhelming.
Well, according to PCS - who we know only updates their lists once a signing/extention has been confirmed by the team - QS is still only at 25, with Moscon. So, remind me who the last two riders rumoured to join/have extended are.
Of course, it is possible that the last two riders have in fact been announced, but that PCS just hasn't seen it yet.
