Rear Sprocket Weights

[twowheels]

I'm busy prepping the wheels on my 2012 300 Race, and in the course of that I removed the 48T Talon Radialite sprocket in lieu of a 50T Ironman chainwheel. There were a couple other new sprockets in the shop that I measured for comparison.

Talon Radialite 48T (no inner ring) - 9.95 oz
stock GasGas 2011 aluminum 48T - 11.35 oz
Ironman 50T steel - 20.30 oz
Supersprox tri-metal (2011 SixDays, Race) 48T - 25.8 oz !

You could imagine that a 48T Ironman might sneak in under 20 oz, or less than 80% of the Supersprox rear. Congrats to GasGas for spec'ing the Talon and shaving the weight, but if you're after a steel replacement, you'd have to think the Ironman is the better choice.

Good thing GasGas doesn't "spec" riders - at 3,760 ounces I might not make the cut.

Interesting stuff. I'm a fan of the Ironman sprockets, and I can vouche for their warranty also. I thought the whole purpose of the Supersprox was to get the strength of steel, but still keep the weight to a minimum. I guess not.

But how long will a Talon last compared to the supersprox? The ironman does sound like the way to go.

Thanks for posting this up. I've used the Ironman and they are great.
