Description
The 25681-V2 is a critical upgrade for any chain-driven race car. In Micro Sprint racing, chains are subjected to extreme tension and high-frequency vibration. If a chain breaks or “walks” off the sprocket, it can destroy engine cases, damage the rear axle, or cause injury. This guard creates a “tunnel” that keeps the chain indexed on the sprocket even during heavy chassis flex or rough track conditions.
Detailed Technical Specifications
1. V2 Enhanced Design
-
Optimized Clearance: The “V2” designation indicates improved internal geometry, providing more room for heavy-duty O-ring chains and preventing the chain from “slapping” the guard under deceleration.
-
Lightweight Efficiency: CNC-machined to remove unnecessary material, ensuring that adding safety doesn’t add significant unsprung weight to the rear axle assembly.
-
Structural Rigidity: Engineered with a reinforced profile to prevent the guard from bending or vibrating into the path of the chain.
2. Quick Change Integration
-
Direct Bolt-On: Specifically designed to mate with the JOES Quick Change Sprocket Carrier. This allows the guard to stay perfectly aligned with the sprocket, even when you swap gear ratios.
-
Rapid Maintenance: The design allows for easy inspection of the chain and sprocket teeth without removing the entire safety assembly.
-
Axle Positioning: Mounts securely to the carrier hub, ensuring that as you slide your hub for track-width adjustments, the guard moves with it for perfect alignment.
3. Chassis & Engine Protection
-
Containment Shield: In the event of a chain snap, the 25681-V2 helps contain the “whip” of the chain, protecting the expensive engine cases and the driver’s cockpit area.
-
Debris Deflection: Helps shield the chain and sprocket from large clumps of mud or track debris that could cause a derailment mid-race.
