Rabobank pro rider Michiel vd Heijden tweeted (and apparently quickly deleted) this image of his presumably prototype Giant TCX Cross bike adorned with what appear to be Shimano hydraulic disc brakes and levers.
While Shimano’s official comment is “no comment” for now, it looks very much like it could be a Dura-Ace level hydraulic road brake system, which is something we’ve heard rumor is coming. Based on appearances, the hood ends are barely if at all bulkier than standard Di2 levers, meaning the master cylinder is tucked inside the Di2 levers rather well. While the photo isn’t big enough to see details, you can make out the silver banjo leading into the calipers, indicating they are indeed hydraulic brakes. Rotors look like Shimano’s Ice Tech parts, but the wheels are blacked out, leaving us only to guess as to their true nature.
We find it quite entertaining to see this pop up on a Giant cross bike after being assured that they weren’t working on a disc brake cyclocross bike, but here it is.
Thanks to everyone that sent this in!
