Enduro Bearings has added their own take on ceramic bearing pulley upgrades for the SRAM Eagle group. They start with an alloy center for stiffness, then coat it with a Delrin outer so it’s quiet and doesn’t wear the chain. It’s not just the construction that sets them apart, it’s the third wheel that’s available:
Because cable friction sucks, right? Why not go ahead and upgrade the idler wheel, too? Granted this one’s not moving much compared to the pulleys, but they added one more benefit: There are no holes to collect mud.
The set of pulley wheels will retail for $229 and come in the stock 12/14 tooth configuration SRAM uses. Throw in the idler to make it a complete kit at $290. Late May early June for both.
They’ve also developed a new line of stainless steel bearing equipped bottom brackets for the SRAM DUB crankset. All of the BB options will be on offer, and ceramic options will follow soon enough. They’ll use a 29mm ID built into the chassis, so no sleeves or adapters to fit the 28.99 spindle from SRAM.
