• CDJオリジナルのBROMPTONパーツの再販を開始いたします!


We have a rich experience of designing and producing carbon parts for automobiles and motorcycle so many years.Since we’ve got involved bicycle repair and custom, We’ve been looking for something new.And then we eventually found Brompton could be suitable for our intention.Very Welcome and relish lightheartedly.



CarbonDry Protec is our original and very special technic. We have acquired the utility model patent.
We produce the CFRP on the metal material directly. 
Before working, all painting must be cleaned off so weight will gain very few. 3k twilled carbon cloth makes elegance and gorgeous.
