Extremely high tensile strength 7005 aluminium alloy requires heat treatment. Its developed for the highest requirements, very stiff and fatigue resistant, corrosion resistant, nonshearing; double butted which makes it suitable for very light tube-sets with a high level of stiffness.

Our bicycles with RFR-geometry stand out by their sports character. The riding characteristics, rider comfort and rider safety in particular are taken in account for each individual bike category.

To protect our high-end aluminium frames, they are built with the CUBE Frame Save System replaceable derailleur hanger. The thread is in the hanger and not in the frame as usual. In case of a crash, this hanger can be easily and quickly replaced by a new one.

Joints in high-quality aluminum frames are specially finished via this method and so create the impresssion of seamless tube design. This generates the visual effect of molding and ensures high load-bearing capacity.

We are not the first ones to present 29ers to the market. But it's only for 2012 that suspension fork manufacturers have been able to fulfil our demands concerning the geometry. We ran innumerable tests to develop the Agile Ride Geometry in our 2012 series of big wheel bikes. Two important details lead to the very agile character. Increased fork offsets let us achieve the same trail as our 26” bikes without having to steepen the head angle, thus maintaining generous toe clearance to the front wheel. Secondly we shortened the chain stays without compromising the seat angle. We invented a patented construction to mount the front derailleur to give us more tyre clearance while keeping a conventional seat angle, leading to a perfect riding position for every rider size. These measures lead to a natural riding position. Every mountain biker will feel immediately at home on a CUBE 29er.
