🆚 Sintered vs cermet (quick comparison)

Feature	Sintered (iron sinter)	Cermet
Heat resistance	Superior at very high temperature	Good
Torque capacity	Very high	Medium to high
Clutch feel	Very direct, “on/off”	More progressive
Durability	Excellent (endurance / drag)	Good in moderate use
Best use	Extreme competition	Fast road + trackdays
Road use	Not recommended (harsh engagement)	More comfortable

✅ Why choose this rigid sintered disc?

• Designed for the most demanding race environments
• Maximum power transfer and very direct response
• Reliable and consistent under high loads and temperatures
• Custom manufacturing possible to suit your gearbox

Tip: a rigid disc is harsher than a disc with a sprung hub. Recommended for competition (rally / track) with the transmission and clutch actuation in good condition.
