Good question. I definitely want to pedal this bike a lot - though it will be a beast. I'll have to get short little crank arms. I'll also have to specify a "lowering" of the dropouts when it comes time to commission replacements. I want to go 2" to the rear already. For every 1" down, that's like adding 2" in wheel diameter, right? Maybe I'll have to go 2" down, 2" back. A longer shock would help too, wouldn't it?

I love how there are as many genres of bikes as there are breeds of dog. Beach cruisers, trials bikes, BMX, I can tell these apart. But I can't tell between some of the close cousins - what makes a DH bike different than a FS mountain bike?
When I was talking to Project321 about putting a Lefty on the Norco, they warned me a Lefty is not tough enough for DH use. That's fine with me, at age 44 I don't think I'm in the shape, nor frame of mind, to take up DH cycling. This build is more along the lines of Fractal's A-Line... a way
overbuilt commuter bike where I don't have to swerve around potholes or blink when taking curbs. I'm sure the Lefty will handle that!

I'll be using a low KV Astro 3220 run through a Recumpense DaVinci drive. The Astro is on order.

That's my plan! DaVinci drive will be very light compared to those monster motors people are putting on these bikes. And forward in the triangle mitigates its unsprung weight even more. Hell, maybe I won't even need a chain tensioner on the left side - we'll see.
