Sick of your chain dropping mid-ride on a technical descent or a long gravel grind? A worn or mismatched chainring is usually the culprit. This narrow wide 3-bolt chainring is engineered to lock your chain in place across a full range of tooth sizes and offset options, so you can focus on the trail ahead — not fumbling around roadside with a greasy chain.

Why Customers Love It

🛡️
Chain stays put, always
The alternating narrow and wide tooth profile grips each chain link precisely, dramatically reducing the chance of chain drop on rough terrain. Whether you're hammering through rocky singletrack in the Blue Mountains or grinding up a fire road in the Dandenongs, your drivetrain stays engaged.
⚙️
Three offset options, one solution
Available in 0mm, 3mm, and 6mm chainline offsets, this chainring lets you dial in the perfect chainline for your specific crank and frame setup. Getting the chainline right reduces drivetrain wear and improves shifting precision across all your gears.
🎒
Lightweight 7075 alloy build
Machined from 7075 aluminium alloy with T6 heat treatment, this chainring delivers an excellent strength-to-weight ratio. The 32T version weighs just 63g, while the 38T tips the scales at only 78g — meaningful savings without sacrificing durability on demanding Australian trails.
Wide drivetrain speed compatibility
Compatible with 8, 9, 10, 11, and 12-speed drivetrains, this chainring works across a broad range of setups without requiring a full drivetrain overhaul. Pair it with your existing SRAM 3-bolt crank and you're ready to roll.

Narrow Wide Tooth Profile — Engineered for Chain Retention

The alternating narrow and wide teeth are precision-machined to match the inner and outer links of your chain, creating a mechanical grip that keeps the chain seated even under heavy vibration or sudden load changes. This is especially valuable on Australian trails where loose rock, roots, and corrugated fire roads can bounce your drivetrain around constantly. No chain guide required for most setups.

Three Offset Options for Perfect Chainline Alignment

Chainline offset matters more than most riders realise — a misaligned chainline causes accelerated wear on your chain, cassette, and derailleur. With 0mm, 3mm, and 6mm offset variants available, you can match this chainring to a wide variety of crank arm designs and frame geometries. The 3mm and 6mm offset models cover tooth sizes from 30T to 38T, while the 0mm option runs from 32T to 40T.

T6 Heat-Treated 7075 Aluminium — Built to Last

7075 aluminium alloy is one of the strongest aluminium grades available, and the T6 heat treatment process further improves hardness and fatigue resistance. This means the teeth hold their shape over thousands of kilometres of riding, resisting the wear that softer alloys suffer from. It's a material choice you'd expect on premium components, available here at an accessible price point.

⭐⭐⭐⭐⭐

“Fitted the 34T 6mm offset to my hardtail and the chainline is spot on now. Haven't dropped the chain once since swapping it in — been riding the trails around Stromlo regularly and it's been flawless. Solid bit of kit for the price.”

Matt R. · Canberra, ACT
⭐⭐⭐⭐⭐

“Was sceptical about a budget chainring but the machining quality genuinely surprised me. Teeth look sharp and precise, and the narrow wide profile grips the chain really well on the rougher sections of the Brisbane Valley Rail Trail. Very happy with it.”

Sarah K. · Brisbane, QLD
⭐⭐⭐⭐⭐

“Picked up the 32T 3mm offset for my gravel build and it dropped right in on my SRAM crank without any fuss. Shifting is smooth and the chain stays put even on the rougher gravel roads down here in Tassie. Weighs next to nothing too.”

James T. · Hobart, TAS
⭐⭐⭐⭐⭐

“Great value upgrade. I went with the 36T 0mm offset for my XC bike and it's been running perfectly through the trails in the Perth Hills. The T6 alloy feels genuinely tough — no flex or creak even when I'm pushing hard on the climbs.”

Lauren M. · Perth, WA
