All Crankbrothers pedals require periodic maintenance in the form of the Pedal Refresh Kit, which replaces the bushings and bearings and gets them spinning like new. The cleats — made of brass — wear out as well and require replacement roughly once a season, along with the required-for-carbon-soles Shoe Shields.
Unfortunately, there is one kind of wear which puts the pedal near the end of its life: pedal wing wear. Above you can see the pedal wings on the Eggbeater 3 pedals from my Specialized Camber, which worn to a point.
The wings are normally box shaped, providing a nice even load on the cleat and sole of the shoe. After wearing to a point the cleat and Shoe Shield wear are accelerating, to the degree that my cleats have worn out mid-year instead of late autumn.
With all this wear put together, pedaling my Camber felt a bit vague and I’d get squeaking and clicking sounds from the pedals when putting down a lot of steady power. Flipping the pedals 90° to change up the engagement would help, as some of the wings are worn less than others, but it’s now time for the pedals to go.
(Instead of replacing with new Crankbrothers pedals I’m giving Shimano PD-M8100 (Deore XT M8100) SPD pedals a go. I’m hoping the larger contact area between the cleat, pedal, and shoe lugs will help with some foot pain problems I’ve had during longer rides. I also expect cleat replacement will be less frequent, costing less long-term. I have concerns about how well SPDs will clear snow and/or permit very fast exit when suddenly stopping on technical sections, so I won’t be selling off my remaining Eggbeaters any time soon.)
