UUDiw_1_US Ultralight Ultegra DI2
UNSTOPPABLE WHEN THE ROAD TILTS UP
LIGHTWEIGHT AND INCREDIBLY RESPONSIVE
The meticulously-designed EVO is among the world?s lightest frames. Surefooted and responsive with remarkable descending manners, the EVO pairs gossamer weight with instantaneous power transfer.
A climbing bicycle where rhythm changes are simple, immediate and with exact precision. With complete vertical and lateral rigidity, BH has managed to unite lightweight, rigidity and compliance thanks to the EVO BB386 bottom bracket, tapered head tube, 27.2 mm seatpost, asymmetrical chainstays, a one piece carbon fork and a shorter wheelbase. The ULTRALIGHT frame weighs 700 gr* in M size and 820 gr* in the case of the Ultralight.
AGILE, STABLE AND EFFICIENT
BH has always been faithful to a principle: Develop agile bicycles designed and engineered to effectively convert the rider?s power and strength into speed. The Ultralight frame is the ultimate expression of this centenarian philosophy applied to competitive cycling. The Ultralight is everything you expect in a top level racing bike; extremely lightweight, laterally stiff and very efficient. It is an ideal frame design for producing the best results from any rider. The minimalistic look was designed and engineered around our Hollow Core Internal Molding Technology, resulting in the lightest, yet stiffest frame we have ever produced. The power transfer from rider to wheel is second to none. Designed to climb, the development team applied this motto to every aspect of the frame, ultimately producing a frame specifically suited for racing. Climbing, descending and breaking free from the Peloton is made easier and requires less effort thanks to the incredible stiffness-to-weight ratio of this proprietary carbon blend, resulting in uncompromised frame responsiveness.
The bottom bracket of the Ultralight utilizes the BB386EVO architecture and measures 86.5mm in overall width. This bottom bracket design offers the Ultralight frame a greater surface area for improved lateral frame stiffness. The BH designers were able to increase the cross sectional areas of the tubing while reducing overall wall thickness, thus increasing the torsional stiffness in the bottom bracket. The result is increased lateral frame stiffness, improved efficiency and total control with every turn of the pedals. This design has also enabled BH to increase the size of the down tubes diameter, thus reducing the thickness of the walls and increasing the torsion stiffness by 166% and the rear stiffness by 125%. As a result, the rider may place more demands on the frame, particularly when going uphill, putting all of his/her effort into speed and power.
FINE-TUNED GEOMETRY FAVORING PRECISE AND IMMEDIATE CHANGES OF RHYTHM
When the road is inclined, the Ultralight is at its best. It offers an experience that fuses the bicycle and the rider, creating a single unstoppable machine. Its studied geometry converts it into an easily-maneuverable bike that is explosive, quick to change directions and follow any path with great precision. This design allows for more precise and fast speed changes, hugging curves at high speeds, attacking uphill climbs either seated or standing, with increased explosiveness, transforming every ounce of energy into power so as to get the best performance out of the most complicated terrains.
CONVERTIBLE INTERNAL CABLE ROUTING
The innovative Ultralight cable guide system offers the possibility of easily integrating mechanical or electronic systems, guaranteeing maximum protection and ease of set up.
