Evotech Performance Rear Spindle Bobbins are crash protection accessories that mount through the rear wheel axle to protect the swingarm, sprocket carrier, and axle ends during a tip-over or slide. They are designed to be the first point of contact with the ground — absorbing and deflecting impact before it reaches costly drivetrain and suspension components.
Construction
- Injection-moulded nylon outer for smooth, controlled sliding during a crash
- Aluminium inner core for structural strength and secure axle fitment
- Roll-threaded stainless spindle rod passes through the rear wheel and swingarm assembly
- Red-anodised hub stop on the exhaust/non-drive side secures the spindle rod firmly in place
- Nylon outer rotates independently of the aluminium core, reducing rotational stress on the wheel during impact
Frequently Asked Questions
How do rear spindle bobbins protect my bike? They extend beyond the swingarm and axle ends, contacting the ground first in a slide and preventing direct impact damage to the swingarm, sprocket carrier, and rear axle.
Why does the nylon outer rotate? The rotating nylon outer reduces stress transferred to the wheel during a slide, minimising secondary damage to the wheel bearings and axle assembly.
What is the red component? The red-anodised hub stop secures the spindle rod on the exhaust side of the bike, ensuring the bobbin assembly remains firmly in place.
