Using your Quad Lock Stem Cap Mount is easy. First, install it securely between your bike's stem and stem cap. Make sure it fits well with your stem angle. You can choose to mount the lever head on either side of the dual - sided head design for the best phone viewing position. When you want to use your phone apps while riding, like Ride with GPS or Strava, just twist and lock your phone onto the mount. To take it off, say for a photo or a call, it detaches just as easily. As for maintenance, keep it clean. Wipe it down with a soft cloth after rides, especially if it gets dirty or wet. Avoid using harsh chemicals as they might damage the aircraft - grade aluminium. Also, regularly check the mount for any signs of wear or looseness, and if you notice anything, it's a good idea to have it looked at or replaced to ensure safety and performance.
