Rohloff SPEEDHUB 500/14 A12 DB OEM2 36H
- Hub with Hub-cap with mount for special brake rotors
- Twist shifter
- Shifter cables
- External gear mech
- OEM2 axleplate to anchor output torque to the rearmost mounting hole of ISO2000 brake caliper mount.
Attention! This is not a thru-axle hub, but thru-axle compatible.
The A12 is a special gearhub.
Thru-axle frames are different by almost every brand. This is the reason why measurements have to be made on the frame. We at Booda Bike have the permission and the tools to do that. The process is made in Budapest in our headquarter. Of course we can help in the transporting.
- Measurements have to be made on the frame. Your frame has to be transported to our headquarter in Budapest, Hungary. Please get in contact with us. Contact infos can be found in the contact page.
- When the frame is in our office, we measure it. The datas are going to be sent to the Rohloff HQ.
- Rohloff is sending the appropriate hub to us.
- As the final step we will notify you and send the frame with the Rohloff A12 gearhub back.
- Enjoy the ride!
