Warp 9 E-Ride Pro SR/3.0 rear axle kit (12mm)

The Warp 9 E-Ride Pro SR / 3.0 Rear Axle Kit (12mm) was engineered to correct several shortcomings of the OEM rear axle system while making wheel removal, chain adjustment, and rear wheel alignment easier and more precise.

✅ BIKE FITMENT

• E-Ride Pro SR
• E-Ride Pro SS 3.0
• E-Ride Pro 4.0

Why Upgrade?

Warp 9's solution starts with a completely redesigned axle and axle block system that eliminates slop and creates a much stronger, more precise fit.

The Warp 9 axle is longer than stock and works with custom axle blocks that have a precision-fit bore matched to the axle diameter. The axle is also keyed to the axle block, preventing rotation and allowing wheel removal and installation with only a single 17mm socket.

The billet axle blocks are precision machined for a much more secure and accurate fit than the stock axle blocks, improving wheel alignment and reducing movement under load.

The axle blocks also use a captive adjuster design. Unlike the OEM setup, turning the adjuster bolts positively moves the axle block forward or backward, for smooth, precise chain adjustments without fighting loose components.

To complete the package, the kit includes Grade 5 titanium chain adjuster bolts and matching lock nuts. Titanium offers excellent corrosion resistance and eliminates the rust and seized-adjuster issues common with the OEM hardware.
