North Shore Billet Idler Pulley (Norco Range HP)
Idler pulleys on high-pivot bikes lead rough lives. They’ve generally got fairly low tooth counts, are heavily loaded, often with not much chain wrap, and bear the brunt of whatever cross-chaining is happening at any given moment. North Shore Billet has a range of aftermarket options to replace worn-out stock idlers, and we’ve spent a full year on their Norco Range version to see how it holds up.
