CDJ Big Pulley Kit (BPK) has some advantages.
1) Pedaling with the BPK is lighter than normal derailleur because friction loss should be decreased. Several customers reported their average speed increased more than 2km/h by their cycle computer.
2) You can use Outer/Low (front outer gear and rear inner gear) smoother than with normal derailleur. Or quite difficult to use like this with normal one. When you ride a bike on the uphill road, once front gear changes inner then you should also change rear gear. This means frequent and futile action will make time loss and to get tired. So the BPK makes you airily.
3) Both outer and inner CFRP (dry carbon) plates give you not only steady capability but also visually beautiful that makes you a sense of superiority. And you can choose pulley color as your preference.
4) You will experience an obvious distinction. Please enjoy to ride a bike with the BPK !!
