My preferred fatbike pedal is the [Mallet by Crank Brothers](https://www.crankbrothers.com/product/mallet-3-new) – technically a downhiller’s pedal, but perfect for winter riding because the big platform supports your foot even when you can’t or don’t want to clip in.
I’ve been using a pair of Mallet 3s for about a year and a half now, through at least four fatbike ultramarathons plus untold snow and gravel training miles – tough use, but without any trouble at all.
Till a ride about ten days ago, when the left one failed on a short ride near home. I limped back to the house and wrote to Crank Brothers to see about repair or replacement. They told me to send the pedals back. Today, I received the repaired pedals – rebuilt at no charge. I like that they still look worn, but aren’t now worn out. Pretty sweet. Great customer service.
