CERATIZIT UK & IRELAND LTD
The Spanish company ROTOR is already known by cycling enthusiasts. The Madrid-based company is recognized for its high-quality bike components, especially for its unprecedented Q-Rings. These chain rings are characterized by their unique oval shape, which aim to optimize power transmission from the cyclist to the drivetrain all in an effort to efficiently propel the cyclist forward. Cycling pros, such as the 2013 world road champion, Rui Costa, swear by ROTOR´s cranks and Q-Rings. These products are produced in an extremely innovative CNC machining environment from the Spanish high-end component manufacturer EDR System using WNT tools.
The basic idea behind Q-Rings originated from a project conceived of by students of the Polytechnic University of Madrid, the epicenter for technological development and aeronautical engineering in Spain. The first prototype emerged in 1995 and was created in collaboration with the university´s manufacturing department. After ROTOR´s first test bicycle was launched internationally, a certain Dr. Conconi became interested in the system.
The well-known sports scientist carried out a study on the system´s performance and concluded that the ROTOR´s crank system had significant advantages in comparison with common systems. Dr. Alfredo Cordova of the renowned University of Valladolid also came to the conclusion that the ROTOR´s system had significant biomechanical benefits. The reason could be quickly explained: the oval Q-Rings optimized the cyclist´s performance by allowing a fluid pedal stroke. The primary goals of Q-Rings focused on minimizing the negative effects of dead spots during a rider´s pedal stroke while maximizing power output. ROTOR Q-Rings are crafted from CNC machined 7075 T6 aluminum. The external area is hard anodized and leads to a permanent and stable surface structure.
All of ROTOR’s bike components are exclusively manufactured by EDR System. Enrique Del Rey, who established the company 30 years ago in Madrid, initially concentrated on the design, development and manufacturing of products and accessories for motorbikes. This industry sector was developing slowly in Spain at the time. A few years later, Enrique Del Rey began to get noticed for his innovations and continued to develop further. In the 1990s EDR was one of the first manufacturers to combine aluminum and titanium in bike components and as a result, made a name for himself not only in Spain, but also abroad.
Today, there are more than 16 lathes and machining centers from the machine manufacturer DMG Mori in the 1600 m² production facility. EDR is able to produce small, medium and large series productions at a rapid rate. Enrique Del Rey’s newest investment is the 5-axis-machining-center DMU 80 from DMG Mori.
“This machine makes us unique in our sector because we are able to manufacture complex parts and then replicate the process in series productions,” Del Rey said. EDR also has other multitasking machining centers with which they are able to handle all the necessary processes from start to finish.
WNT provides 90 percent of the tooling required by EDR System for the large machine investment. And this for good reason…not only is Enrique Del Rey satisfied with the 45,000-strong product range and 99 percent stock availability but, “WNT also provides us with technical support through their engineers and next day tool delivery,” said the EDR System founder. The cooperation of these three companies and their high quality results are what allow cyclists to improve their performance with ROTOR Bike Components.
