OK, I messed with the torque settings. I set it all the way up to "dynamic," whatever that's supposed to mean.

The short of it is that the Neu 1512 1.5Y doesn't have nearly the raw power of the 9XL. I have the Neu geared 17/46 and it still doesn't equal what the 9XL was doing at 14/46.

Still in all, the 1512 only gets up to around 165*F. I was hoping for lower temps, but they don't seem to get any higher either. If I run it for 5 minutes, it temps 165. If I run it for 15 minutes, it still temps 165. If it keeps running like that, I'd be fine with it.

I haven't tried the 18T pinion yet and I can still go down to the 44T spur. I'm just afraid to try it because I'm already getting a bit of cogging.
