Duke Racing Wheels are a company based in Chambretaud, France. They have a small selection of products available, with an emphasis on wheels. Being the consummate admirer of small specialized parts, I immediately was struck by the tubeless valves they sell. Currently, there are very few choices for tubeless valves, so a new addition is welcome. The valves come in six different colors and weigh 4.8 grams, with a claimed weight savings of 36% over traditional valves. I think it’s great being able to customize your bike down to the smallest details, and these valves fulfill that desire. Duke Racing Wheels are also producing quick release levers and stems, both of which I will review down the road. The website has English translation making it easy to peruse the product. It is definitely worth a look.
