Designed for XC cycling, this aggressive bike facilitates technical descents and inspires riding confidence and stability.

Its unique technology is

• The Ultimate RC represents a huge step forward for the BH R&D team. It has exactly the same shapes and design as the Ultimate; longer upper tube, short chainstays and an advanced steering angle. It incorporates Toray T800 and T700 carbon fibres that guarantee the perfect balance between stiffness and lightness.

It’s different because

• It incorporates a technology for monocoque frames that applies high pressure in the mould to reach the highest levels of compact material and eliminate inconsistent pressures in the frame that create bubbles and imperfections. This manufacturing system allows control and optimisation of the ideal thicknesses on the different parts of the frame.

ULTIMATE DNA

• The key areas in the development of the new Ultimate RC are the same as when we developed the Ultimate Evo: low weight, a 20 mm increase in reach, very short rear chainstays - 420 mm - and a 68º steering angle.
• The goal was to create a bike that would achieve optimal balance with the rider, that was even more manoeuvrable on climbs and that would enhance its performance during descents and on more technically challenging terrains.

PERFORMANCE CARBON LAYUP

• The Ultimate RC frame was built by applying the moulding technique used in top-of-the-range road frames. The special arrangement of the carbon, resin and high pressure applied to the inside of the mould prevent pressure variations and imperfections, essential in the construction of a lighter, more rigid bike with better overall performance. M, ±5 % weight variation.

OUTSTANDING AGILITY

• Its ultracompact chainstays, only 420 mm, ensure agility and stunning acceleration. The perfect combination of stability on descents and reactivity on climbs.
• It also features a dropout with a similar appearance to the BH road bikes, more solid and compact, which reduces the width of the rear chainstays by 2 cm. And it gives the frame's new lines a stylish and sleek appearance.

MAXIMUM STIFFNESS

• The design of the Press Fit92 bottom bracket box has allowed us to widen the diagonal tubes to provide maximum stiffness and minimal bending between the front and rear triangles.
• This guarantees strength in this key area, where the pedalling forces are directly applied. It is completely integrated into the frame to provide greater rigidity and precision when changing gears.

FLAT MOUNT TECHNOLOGY

• The BH Ultimate RC features countless little details. It comes with a bracket for the Flat Mount brake clamp, to help ensure a light weight and the best possible integration .
• Despite its minimalist design, the frame has been designed to comfortably withstand the stress produced by the rear brake.

BLOCKLOCK BY ACROSS

• One notable feature is the addition of the Blocklock steering system by Across, which restricts the turning angle of the handlebars to 150º. No more hitting the upper tube with the handlebars!
