Big Pulley Kit for Shimano Short Matte

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) Carbon cages, 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 cage color as your preference.

4) You could use up to 34T rear gear with this short cage BPK depending on the setting.

5) You will experience an obvious distinction. Please enjoy to ride a bike with the BPK !!

6) Low range decreasing friction loss is similar to V3 model. But more than middle range, V3 PLUS is slightly better decreasing than V3. So if anything, we suggest you to use V3 PLUS for TT or Triathlon.
