These are the most frequently asked questions about the Defender frame lock.
I positioned the Defender RL where it was supposed to fit on the bike against the seatstays. The problem is that my bike has a rear rack that blocks this lock from being installed properly. Is there any other way to mount the lock?
You can mount the Defender lock however you can fit in on your bike. The seatstays are the recommended location. I had to mount mine on the underside of the seatstays, because the rack didn't leave enough room to mount it on top fo the seatstays.
