I purchased this to use on my bicycle and with a Garmin 60CSX. Installation was simple and all parts were included. Note that it does include two rubber strips of different thickness for different diameter handle bars. The clamp also has a positive clamping motion as it is hinged which makes it a bit more secure and easy to mount. Once the unit is clamped onto the handle bar there is no adjustment, so you may need to readjust after you ride. We do mainly riding on the street but have done 50+ miles with the GPS and have had zero issues. It is easy to come off and stays on just fine.
