Yup, M9000 + Zee. Problem I just noticed is that the lower limit screw doesn't even come close to being in the right place to limit it to six gears as shown. Not sure what to do about that.

 Longer bolt and call it?

 @whattheheel: You may very well be right. I think it's a matter of angle rather than length (or at least that's what I tell my girlfriend). It's hard to explain, but the nub that the limit screw is meant to hit sits in a totally different place in most gears.

 Custom bend all the bolts!! And nice on the Nokon! Haven't used it for ages tho.

 @whattheheel: Thank you!! @sherbet threw a few segments of it at me a year or two ago, but I had no use for it until now. Very stoked now that it's on there. I was gonna f*ck around with the limit screw some more at the end of the day but some dude came in five minutes before closing.....and asked me to price out multiple road groupsets for him.

 I walked over to the liquor store about 20 minutes ago and got some beer! Closing the shop the right way!!

 @whattheheel: I've got a high school co-op student working for me right now but this kid doesn't have a fake ID! If I'd known I couldn't send him to get me wobblies I wouldn't have agreed to take him in, damn.

 Who do we know that could bang one out for him? Somebody on here has to be able to make us a fake for him?

 Summon'd.

 I think you now have to tell him how pretty his bike is?

 Just credit where it's due for the baller housing.

 @crs-one: How pretty is your bike? It's very pretty. Very very pretty.

 Pretty good sherb.

 Start with a cassette that matches your shifter. I'm using a 10-speed Saint, so I started with 10-speed Tiagra. You have to be a bit careful and a bit lucky because mid to high-end MTB cassettes often place multiple gears on a single aluminum carrier. Some of the very cheapest cassettes use entirely individual cogs, but riveted together...once you pop the rivet off, you can use them individually and there's no structural damage to cogs either. What you want is a cassette that either doesn't group them at all, or groups them in such a way that you can use just 5, or just 6, or just 7. I can't remember what cassette I used for this last time but I think it was a Shimano HG81. Then you just toss the gears you aren't using. My Hadley SS hub fits six gears and one spacer, which with this cassette gives me an 11-19 ratio. In the past I've experimented with taking cogs out of the middle of the stack rather than just pulling the 4 easiest gears off, but shift quality suffers because the ramps are no longer lined up quite as intended.

 @crs-one: awesome. Thank you very much for the great explanation.

So then I have two more question, how do you get the shifter to not accidentally shift too far putting the chain into the spokes?

Is it just a longer limit screw from the hardware store?

What do you use for a spacer? Is there some conveniently sized thing that works or do I gotta make something up myself?

 @Thepureface:

The limit screw question is a good one...for the vast majority of derailleurs, just toss in a longer screw like you say. For this particular one, that won't cut it and I need to figure something else out. Watch this space I guess. One way around that is to set the derailleur up with the shifter already shifted into an easier gear, that way you use the shifter as a limit rather than the derailleur. I've tried this in the past with a similar setup (6-speed made of of 9-speed SRAM stuff) and it works. You end up with a few gears worth of slack at the top end, however.

Spacer - I just use the plastic spacers that go in between cassette cogs. I only needed a small one because this is technically a singlespeed hub. There's not a lot of space to take up.

 @crs-one: alright, great thank you very much for explaining.

 @crs-one: If Hadley hub is a single speed hub, what cassette body do you use?

 @meser: I use the stock titanium singlespeed cassette body. It's the regular Shimano spline, just shortened, so the maximum number of gears you can fit is six. The idea is that when set up singlespeed, you've got some room to adjust the cog's position for a better chainline.

 @crs-one: Ok i understand. I thought that your hub Hadley SS is with driver 9t or 10t.

 @meser: To my knowledge, Hadley doesn't offer a driver. It's a shame because this is an extremely reliable, fast, high-quality hub, and a driver option would fit great.
