DirtyBike Steel Rear Sprocket for Surron Ultra Bee

The DirtyBike Steel Rear Sprocket is a simple way to add rear-wheel torque and quicker acceleration to your Surron Ultra Bee. A larger rear sprocket gives the bike more pull out of corners and through technical terrain, with a tradeoff in top speed. We prefer steel sprockets on our own bikes because they’re stronger and more resistant to bending when riding gets rough. Built from OEM-quality zinc-coated steel, the DirtyBike sprocket offers durability and corrosion resistance, with beveled teeth for smooth chain engagement. Our go-to size is 52T. It adds torque and acceleration while keeping the rear axle positioned to maintain our preferred wheelbase with the appropriate chain length. It’s a setup we like for technical trail riding and hard enduro.
