Mark has been riding the London streets on his daily commute to work for decades. So when he decided to buy a new bicycle he already had a clear idea of his needs. He had come across the Nua Dual on the internet and thought that its titanium frame and fork, its Pinion gearbox, and its belt transmission would be the perfect base on which to construct his dream bike. We were of course very happy to help.
The Nua Ti-Frame – constructed from Gr9 titanium – perfectly accommodates the fabulous Pinion gearbox. As you may already know, this gearing system was designed by Porsche engineers, so it’s not very different from the sequential gearshift you might find in a Porsche sports car. It is precise, has an enormous range which will handle any situation, and is maintenance-free except for a quick and easy oil change every 10,000 km. In Mark’s case, after discussing his needs, we opted for the 9-speed version.
Of course, the transmission had to be a Gates Carbon Drive CDX belt. With a minimum working life of 20,000 km, without the need to grease or tension, it’s the perfect companion for the Pinion box. Mark chose a red belt to add a splash of colour to his bike.
When it came to tires, Mark’s priority was to reduce the risk of punctures to an absolute minimum, so we installed some robust Continental Contact Plus and added some Zefal anti-flat tape. The 55mm width absorbs rough road surfaces with ease.
We modified the Curana mudguards so that they can be installed without removing the back wheel. That way Mark can use them only during rainy spells. (Wishful thinking from a Londoner, perhaps?)
Mark had a couple of other specific requirements: for example, he wanted to be able to have a GoPro recording at all times; very useful in case of accidents. So we designed a special bracket for the camera, mounted just below the stem.
He also wanted to theft-proof his bike as much as possible, and this we achieved with a superb quality compact Abus lock installed directly on the frame. In this way, the bike’s weight remains centred, and the lock is tidily out-of-the-way but easily accessed.
With the frame protected, it only remained to protect the main components with Hexlox inserts. Here the titanium handlebar:
The wheels (which by the way were laced in-house with Pinion hubs and DT-Swiss 471 rims):
The Gilles Berthoud saddle with titanium rails:
The titanium seatpost:
Even the rear wheel’s sliding dropouts:
And the titanium stem:
Mark’s words in a recent email made us very happy:
“Roberto, the bike is a sheer joy to ride. I make excuses to go out for a ride 🙂 I had a very specific set of requirements, and the superb design and all-round capability of the NUA Dual you custom made for me is the best bike I could have wished for. I love it. One of my friends already called my Nua the ‘Range Rover’ of bicycles – by which he meant it is the ultimate mix of off-road and urban luxury ride :)”
