OK, just went out for a ride with the DNP.
Front crank gear = 48t.
wheel / tire = 26" wheel, 1.95' tire @ 40PSI.
It was quite noisy ( grinding, clicking ) when i first installed it, after i took a ride it has quieted down some. I guess it needs to machine itself even, hehe. There was also a lot of wobble in the freewheel when first installed, that seems to be going away as well.
The downside is that it drags on the wheel more than the shimano. I hope this improves.
Perhaps it is not broken in. I will report back on that later.
The good news is that 11t is perfect for a fairly relaxed pedaling pace at 20-25mph. I hit 29mph, 1mph higher than my previous 10S lipo record. Cool.
I think i can get a higher top speed on 14s, probably a few mph higher.
This makes pedaling into the 30mph zone possible. At a frantic pace on a 26" wheel... but possible
