This Brompfication Chain Tensioner, CNC machined from 7075-T6 aluminiu for Single Speed or 3 Speed Brompton's has been completely re-designed to get a cleaner and more elegant look than the original plastic tensioner. The main difference from the old design is that the tensioner arm now rotate around a pivot bolt mounted directly on the rear hub axle. This make it possible to reduce the bulky base of the tensioner and make it follow the lines of the tensioner arm.

More then 2 hours of CNC machining goes into making each of these chain tensioners. The tensioner is machined from 7075-T6 aluminium, one of the absolutely highest grades of aluminum alloy you can get. By using 7075-T6 aluminium it have been possible for us to design a light weight and elegant chain tensioner, without comprimising on strength and stiffness. With a weight of only 113 grams including the spring and the pivot bolt, just 10 grams more then the plastic version , it is one of the lightest aluminium chain tensioner for Brompton on the marked. The tensioner come with a stainless steel spring that replace the original spring, and a pivot bolt in titanium.

 

  • Hard black anodized 7075 T6 Aluminum to give it an exceptional wear resistant and corrosion resistant surface that will outlast the origianl 10 fold
  • Consists of 1 chain tensioner arm, 1 tensioner base, 1 titanium pivot bolt and 1 stainless steel spring
  • 113 grams including spring and pivot bolt. Just 10 grams more than the original

 

Brompfication Company History: Brompfication was formed by the Danish Brompton fanatic Peter Griebel in September 2010 and was the first company to specialize in producing parts for modifying and tuning your Brompton. The idea behind the company is to design and produce modifications for Brompton folding bikes with a simple design, that are functional, lightweight and durable. 

 While still a small business their passion for improving Brompton bikes have made them a widely known name in Brompton circles throughout the world. Their first product was the awesome Hinge Clamp Set that not only makes folding your bike even easier but saves weight too. Since then many new products have been developed and are all still made in small batches by family run CNC shops in Thailand.
