- **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/GB-3204-0002-0002:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals.

## Description

This bevel gear set includes a [14 tooth pinion gear](https://www.gobilda.com/2306-series-steel-mod-1-5-clamping-pinion-bevel-gear-8mm-rex-bore-14-tooth/) intended to mount to an 8mm REX™ shaft, and a [28 tooth hub gear](https://www.gobilda.com/2307-series-steel-mod-1-5-hub-mount-bevel-gear-6mm-bore-28-tooth/) intended to mount to a 16mm pattern hub. The combination of a 14 and 28 tooth gear creates a 2:1 ratio, which is most commonly used as a gear reduction, meaning the small gear is driving the large gear. Although they can also be used as a 2:1 overdrive if speed is more important than torque. The 28 tooth gear has clearance for a hub with an overall diameter of 32mm. [Sonic Hubs](https://www.gobilda.com/sonic-hubs/) provide the most versatility as they can be mounted on the backside of the gear, but if you’re using 12mm REX shaft as an output you’ll want to use a [Hyper Hub](https://www.gobilda.com/hyper-hubs-16mm-pattern/) on the face of the gear.
