Orange Road Racing Bikes

January 22 2018

We are a company of cyclists, not just mountain bikers, and we live in the heart of some of the best road biking in the UK. With the popular rise in enduro and endurance based sports we’ve found we're covering more miles on tarmac than ever before. It is time for us the bring our own road bike back to the Orange line-up.

With a feature list for our dream road bike we set : Super strong yet super light frame construction, built for distance, designed to climb, descends like a missile. we reckon we’ve ticked off the lot.

We delivered our first carbon fibre road model with the Carb-O in 2012, which is now one of our cult models to those in the know.

Now finally with the advent of bolt-through axle standards, much improved disc braking, and larger volume tyres, we’ve reignited our Orange road bike project to develop a frame and spec package that truly meets the needs of the 21st century rider.

Not all carbon is created equal

Carbon Fibre frames are now ubiquitous in the world of performance road cycling but the quality can vary enormously. The R9’s frame construction is a precision carbon fibre lay-up using materials from Toray in Japan, one of the world's leading suppliers. The frame’s monocoque structure uses a combination of ultra-high modulus unidirectional composite weave, for its high tensile strength. Bi-directional woven sections are integrated into the complex lay-up to reinforce areas of high stress.

For each different size of the R9 frame, the carbon fibre pre-preg' sections are CNC machine cut to fit 3D printed mandrels. These custom mandrels are used during the meticulous lay-up process to construct each of the frame’s sections before the parts go together into the mould. This process creates a strong monocoque structure avoiding superfluous lay-up material and unnecessary joints maintaining an ultra-light frame. 

This fastidious construction process means that when the laid up material is put through the compaction phase, everything is smooth and even, inside and out, avoiding over-built areas that can fail in the curing process leading to structural weak spots.

Precision CNC cutting of the pre-preg' panels also means we can fine tune areas where we need to. Adding extra material to strengthen the flat mount brake mount bosses and keeping the subtly curved sweep of the seat stays lean, light and compliant to provide rider comfort.

Designed primarily with modern electronic gear systems in mind, the R9 will happily accommodate ‘old school’ cables.


 

Overall, we are thrilled with the way the R9 has come together. The perfect lightweight endurance machine for notching up the miles, with large tyre clearances and powerful disk braking making it perfect for all kinds of roads.

  • Frame constructed using High Compaction (HC) moulding.
  • Endurance geometry, combining rider comfort, rapid climbing ability and confident descending.
  • Unique 3D printed PU mandrels and carbon lay-ups for each size R9 frame size gives es a consistent ride & feel across the range.
  • Monocoque frame construction using only four bonded joints for a lighter and stronger frame.
  • Oval-shaped, curved, super-thin seat-stays reduce road buzz and improve comfort.
  • Internal cable routing using injection-moulded stops. Compatible with cable, electric and wireless drive-train systems.
  • Flat mount disc brakes front & rear.
  • 12mm bolt through-axles front & rear.
