Bearings from igus help to absorb handlebar shocks in concept bicycle

igus’s iglidur g bearings have been used in the NOAH (Normally Operated Articulated Hybrid) suspension system, designed by handmade bicycle specialist COFA Engineering. The suspension system was developed as the centre piece of COFA Engineering’s yearly concept bike for the Bespoke UK Handmade Bicycle Show.
Designer Steve Major created a system that would allow greater control over rough terrain while providing a suspension system that would absorb the shock from big obstacles. Breaking with the convention of the main shock absorption over the front wheel, the NOAH system transfers loads to the centre of the bike via double A-arms. These A-arms then feed directly into a centrally mounted suspension system unit, which absorbs the shock.
NOAH allows for longer travel on the front forks (230mm) when taking the bicycle off-road thanks to the suspension system residing in the central A-bars. This linkage allows for the front wheel to move linearly over its suspension range much like a standard telescopic fork, but with the advantage of being able to control and alter the steering angle during suspension travel.
The central linkage also ensures most of the bike’s weight distribution is focused in the middle; this placement allows the rider to control the attitude of the bike with much less effort, helping the bike to travel over rough terrain by absorbing impacts into the centre of the bike.
To ensure smooth movement in the NOAH suspension system, COFA Engineering turned to polymer bearings specialist igus, which selected its iglidur g bearings.

Key benefits of product application
* iglidur g bearings were chosen thanks to their small section profile, ensuring the bike’s weight and size were kept to a minimum. The cost-efficient solution also ensures the NOAH system works smoothly and effectively and, thanks to the self-lubricating nature of all igus’ bearings, requires no maintenance or lubrication, even during excessive use and in harsh environments.
* ‘This was our first experience with igus and they were the ideal supplier for this project,’ added Major. ’They were hands on from the start with workshop visits, provided great advice, product samples and support. Ideally suited for the NOAH suspension system, every bearing size that we needed was readily available to order from the igus website and, more to the point, at the right price. I was really happy with both their support and the products themselves, I wouldn’t hesitate to use igus bearings again for future projects.’
* ’Thanks to the use of igus’ bearings in the NOAH suspension system, we were able to realise the design benefits by removing the conventional fork springs, dampers and other internals,’ he continued. ’The NOAH system is unique and we are now developing the production version, again using igus bearings’
