Durability, reliability, and solid feel are all hallmarks of the Shimano Ultegra pedalset, but the most overlooked feature is the price point per value. SPD-SL design is trickled down from the original Dura-Ace design with slightly less expensive materials to shave some dollars from the price tag. Quality of the pedal is still very high and should give you many seasons of trouble free service.
As with all SPD-SL pedals, the SH-11 cleats have pontoons attached to them which make them very easy to walk in and last a long time. Adjustable tension is easily handled with a one key adjustment.
