At the end of last week, Techno Nankai brought their new product. A 9 teeth driver to run a 1/2" x 3/32" chain (Thin one as BMX race, MTB or road bicycles). We are sure that new product will satisfy all the Nankai users to upgrade their freecoaster. The set is available for the K-Type model (for the 10CKW steel shell and 100AKA alloy shell freecoaster). The use of thinner chain save 50 to 100 grams according our test with khe or shimano chains (it still depends on chain models and length). 
After doing a BMX 'zine for ten years (1987 - 1996) FATBMX made it on the internet. The year was 1998. Here to stay.
