lol. Totally don't get all the conceptual stuff behind what you and Alex and a couple of others do, but I love reading about it. Occasionally the light dawns

Was looking into this for something to tinker with but for future reference. It will not just bolt on. Under further research the one for the jog in the link has a 33 mm bore and the urban express is a 34 mm.

Re: NU50: Modification of the Rear Pully

^^ If you're going this route, I'd recommend purchasing the entire GY6 pulley assembly anyway, as the NU50 only uses 2 guide pins (as opposed to 3). The bore of the ID should be close enough to bolt on, and the extra +1mm in diameter should have a de minimis effect on top speed. CW's post is focused on the variety of angles available for this setup (which, on top of those already stated, is a big perk to the GY6 over the DIY method).

Damn that sounds like a lot of work. How many hours?
