Mr. Serefhan, what is special about your basketball wheelchair, EXTRA?
Demirhan Serefhan: Sports like wheelchair basketball are very tough. Wheelchair basketball is one of the most difficult sports among the Paralympic sports. The players want to be very fast and they don’t want their wheelchairs to get damaged so easily. When you look from their way of thinking, you have to make a wheelchair which is very strong, light and fast. Therefore, we are using a very special aluminium grade which is also used at aeronautical engineering. The type of the aluminium is called "Aluminium 7020". We are shaping those aluminium tubes and plates in accordance with the specific body measures of the user. This method is called "Made to Measure" or "Tailor Made". We are proceeding a very special heat treatment after the final welding. This heat treatment process is very special and unique. Sometimes it is said that aluminium 7020 T6 does not need heat treatment, but we are applying our own methods and the wheelchairs become much stronger. There are so many players who are over 130 kg and couldn’t succeed to break EXTRA wheelchairs.
In addition, we are working with Spinergy, a company for high quality wheels, and manufacturing our own breathable and strong upholstery. Users mostly require an embroidery at the back of the wheelchair. This can be their motto, their name, a logo or a number. This option is free of charge at EXTRA. Actually, most of the options are included in the total price of the wheelchair, i.e. the carbon underseat plate, carbon footrest, straps, ergonomic seating, two antitips and so on. We do not charge those options as an extra cost for the users. We want our clients to have access to a high-quality product with a reasonable price.
