They are very easy for the price to be mounted without problems and enable quick familiarization, because the trigger mechanism is adjustable and you can adjust the Verbindungdstärke between the shoe and the pedal on your own preferences.
Even in tough off-road use, the pedals have been proven, mud and gravel do not affect the Click-mechanism at all and you get used to relatively quickly to the entry and exit. The power transmission is more efficient and makes you feel directly integrated into the system.
I have to still buy the Shimano adapter with reflector SM-PD 22 (Shimano pedals Accessories pedal attachment) to use the Klickies with street shoes can. Overall I am very satisfied with the purchase and would recommend it to anyone who is sometimes on longer tours with the bike on the road.
