Comfort and stability Discover the fun and the benefits of riding with the Keo Classic 3 clipless pedal. Simple to use, it is impossible to adjustment the cleat entry/release tension too low for an easy clip out. Its large and wide contact surface provides excellent pedalling stability. Technologies Chromoly spindle for more reliability The Keo classic 3 spindle is made up of an oversized steel axle with miniature ball bearings (12 mm inside x 18 mm outside) and a needle bearing cartridge for improved wear resistance. A spacer is used to hold the needle bearing cartridge in place. A new method of fitting the spindle into the pedal body also ensures the prolonged reliability of our pedals. Look spindles are only approved after a rotational test of 2 million cycles at 100tr/min with a load of 90kg on the centre of the pedal and an eccentric rotation (creating a shock on each rotation). Look axles are only approved after a rotational test of 2 million cycles at 100 rpm with a load of 90 kg on the centre of the pedal and an eccentric rotation (which creates stress on each revolution). This is equivalent to a sprint by andré greipel of 1700 watts at 100 rpm for 333 hours! This test is much more demanding than the current standard, the iso 4210.
