Minoura Front Guard Roller

The safer guard with caster wheel.
The standard Front Guard is just a fixed solid wall to prevent falling off the wheel when you lose balance. So the tire side wall could be damaged if you hit at high speed.
The unique point on Front Guard Roller is the horizontal caster wheel. The caster wheel spins freely so it will spin together with the front wheel when the wheel touches the caster wheel. That works to reduce the speed gently and safely, then it will push back the wheel to the roller center in order to recover your balance.
The caster wheel height is adjustable to contact the rim earlier than the tire.
Front Guard Roller can be installed on both Action Magroller and Advance.
