Aluminum ratchets are the sweet spot for most riders. They're strong, durable, and give you a smooth, satisfying click when you crank down your straps. Unlike plastic (composite) ratchets, aluminum teeth resist stripping much better, so they hold up well season after season even if you ride frequently.
You'll find aluminum ratchets on mid-to-high-end bindings across all riding styles—from park setups to freeride rigs. They do add a tiny bit of weight compared to composite options, but most riders won't notice. The real benefit is longevity and that smooth ratcheting action that makes strapping in feel effortless.
If you're a casual rider on a tight budget, composite ratchets will get the job done. But if you ride regularly or want bindings that'll last, aluminum is a solid upgrade that won't break the bank. Just don't overtighten—no matter the ratchet material, cranking too hard strips the ladder strap.
