THE ONE refers to the one bike Mario Cipollini would choose as his single bike if he could only ride one. It is the Cipollini RB1K. Adding to the already special nature of THE ONE, this version was made for the 20th anniversary of Cipollini as a cycling manufacturer. This limited edition frame is complete with the usual Cipollini style along with UCI colors. It is a truly unique frame that you will see very few of on the road. Become part of the history of Cipollini and cycling as a whole with this limited frame.
The RB1K builds off the success of the RB1000 and is 20 percent stiffer, 120g lighter, and an all-around dominant road bike. Cipollini loves bikes that are explosive and edgy. The geometry remains largely unchanged with an aggressive seat angle, short 405mm stays, 45mm fork rake, and a short head tube. They have opened up sizing possibilities on the front end, thanks to a new head tube top cap. This cap raises the head tube 18mm over the top tube. This allows for less flexible riders to find the handlebar position they need with the reach they can handle. For those who like to get long and low, the piece can be removed while keeping the stem super low.
The shape of the RB1K has changed in a few ways. The fork has been reshaped for greater comfort, but still slashes like a razor thanks to both the carbon-fiber layup and the straight 1 1/2” to 1 1/2” steerer. The carbon-fiber is still fronted by Toray’s lightweight T1000 cloth. The shaping is still extensive and pronounced. This bike’s head tube is pointy, and the fork-crown nestles into a cutout between the top and down tubes. The downtube curves around the front wheel and the seat tube shrouds the rear wheel, along with extensively shaped seatstays. The dropouts have been reshaped for extra strength.
Wherever you look, this bike has been shaped for stiffness. The downtube flares out at the bottom to help it maximize stiffness. Down and top tubes join behind the head tube, providing an efficient design. Even though there’s a low stack height, the seatstays are big and the seatpost oversized, making this bike an absolute rocket. This bike also comes with features that make it a good choice for just about everyone. The shaping of the fork and stays has been done to give room for tires up to 28mm in width. The Cipollini RB1K The One is a true super bike for the sprinter with a need to go fast.
