CDJ Big Pulley Kit (BPK) for SRAM e-Tap, Red22/Force
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.
4) We also offer you the Middle cage BPK which is suitable for wide range gear ratio as more than total capacity 33t. For example, to use 50/34t front, 11/32t rear that is 37t total capacity should be used the middle cage BPK. So you can choose it depending on where or how you ride.
5) You will experience an obvious distinction. Please enjoy to ride a bike with the BPK !!
