That's rad. I have a set being made from aluminum locally, waiting on these now. The hardest part is getting the chainline dead nuts on. Good call on using black plastic, as that'll be cheaper than painting or anodizing them to get to black.

Boone now has both spacers and a lockring. It's not a cheap solution ($182 for 20T cog plus spacers and a lockring), but cheaper than a new wheel, so there's that. Fortunately I bought an I9 HG freehub a couple weeks ago for my rear wheel, so I don't have to make that decision, though I do happen to have a MS Boone cog sitting in my small parts drawer, so it will be on there someday.

Hi, there, new here! I already bought 2 Boone cogs, but I'm struggling to select the correct spacers, because Boone doesn't make them thin enough(say 1mm) and I don't want to have problems with my chain line (52mm). I'm thinking to buy from Boone one wide spacer with the lock ring (they look clean and sturdy for the trails) and fill the rest of the body with regular HG spacers (1mm). I'm assuming that the outer diameter of the micro spline hub is the same as the HG? Can you help me? Otherwise, those Boone cogs, no matter how artisan they look, will be useless as jewelry. Thanks in advance!

Btw, can anybody provide pictures or video with a complete built with the Boone kit ( spacers, lockring and cog)?

I put up a video on YouTube on how I installed mine. I'll see if I can find it later, but if you search Boone Microspline Singlespeed cog I bet you'll find it

Unfortunately, the microdrive is a smaller splined shell that is slightly larger diameter than XD.
I did my spacers with aluminum tubing and my compound mitre saw after measuring for correct chainline. That process can be done with HG and correct diameter material.
HG carries the right diameter to get away with 1.25" PVC pipe. Don't remember the diameter for microdrive.

Here is the video I made. Thank jeebus I'm not striving for internet fame.
I found that "HG" spacers, as long as they have the tab to fit between the splines, work great as they sit on top of the microspline, uh, splines. But as @BansheeRune said you can always fabricate your own up with some other options. For my video the trickiest part was using the right size headset spacers to step up from the lockring to the cog. This is one area I would absolutely splurge on. The Boone lockring would make that step so much easier.
Hope this helps.

As long as the spacer ID slips over the driver with a close fit, of o the races! Then it is an alignment check, measurements and chop saw time.
While there are a host of commercially available parts, I like to fabricate parts and make it my bike.

Just as territorial as a tomcat...

Thanks for your replies. The way I see it, my Boone cogs pictured above are the most expensive pieces of jewelry I ever purchased thus far with no practical use in the foresseable future. I couldn't find an affordable wheel with HG free hub body to replace the bloody wheel with the microspline (shimano, stop being harsh on me) and thus I thought Boone's cogs were the solution. But the guys there clearly don't know the concept of chainline and they based their calculations without having in mind the length of the end cap drive side. To add more frustration to this, they don't offer narrow spacers (btw, again their spacers and lockring are artisan pieces and that's why I don't want to think or look for other solutions proposed here, I even rejected the idea of visiting a local lathe worker) with diameter of 1mm (yet they offer them for the HG hub!!!). If I knew for sure that their HG spacers will fit the microspline, I would have ordered 2 wide sparers + lockring and a stack of those with 1mm to properly fix my chainline. I think I will keep my SC Chameleon geared (which sucks). Already today I placed an order for my 2nd Kona Unit which I adore. Now I want a trail/XC ss horse...

You will find the microspline body has a smaller OD that does HG. HG spacers would be like a person with a 30" waist trying to wear 38" pants!
Get the chainline sorted, measure both sides for appropriate spacer dimensions and gitter dun.

Thank you for clarifying that HG spacers can't do the job on a micro spline:). Already ordered a surly ss kit and a couple of cogs and I'm camping in my pc room trying to find an affordable boost wheel with HG.

I will probably sell the wheel with the micro spline + drivetrain to recoup some of the money I spent on Boone cogs.

No worries! Just hate to think a fella might order up parts and when they arrive, cannot be used. If you know the make/model of the hub, you might be able to simply purchase an HG driver vs. a whole wheel. Savin bux, brother, savin bux!

Savin bux and cycling are incompatible things, I'm afraid. What keeps me from repurposing my bikes into office furniture (need a couple, three tables btw) is my reluctance towards manual labor, a syndrome I most probably developed since started cycling.

I've already bought and I'm expecting 2 rear wheels ( 27.5 for mullet configuration and a 29), both cost me about the same as the the Boone cogs (shipping included).

Eagerly and patiently waiting to find out who will be the 3rd person to buy microspline Boone ss cogs and his solution :D

Finally, I found a 3rd user of Boone cogs. How did he configure his chainline with a centered cog on the rear hub? Messing around with the crankset?

No offense, but it seems like you are making it harder than necessary. It is no different from any other HG style freehub body with the exception of it being shorter. As @kustomz pointed out above, you just line it up and use spacers. Also, there are HG freehub spacers that have tabs as I pointed out in my video I linked for you above. Those tabs fit just fine on a Microspline freehub.
I ran my Boone Ti Microspline cog for well over 1K miles. On my 157mm spaced bike, with the crankset I was using at the time the Microspline cog sat right on the end of the Microspline unit so I used appropriate spacers. I switched cranks, which moved my chainline in-board, so I just repositioned the cog and moved some spacers around. Just like any other HG singlespeed setup.
Nothing different with Microspline.

measure the width of your seat tube. divide that by 2.
measure from the side of your seat tube to the center of the chainring. add that to the number above. that's your chainline.

take the width of your rear axle divided by two.
135/2=67.5
142/2=71
148/2=74
that's the length from the center of your axle to the end of the axle.

subtract the chainline from the axle half length. put some spacers and a cog on your hub. put a straight edge against the end of your axle and measure the horizontal distance from that plane to where the cog currently is. if it's with 1–2mm of the chainline, you're good. if not, rearrange spacers as needed until it lines up.

this sounds complicated when described in types words, but it's simple enough for any child to figure out. rather than eyeballing it, this takes less than five minutes and gives results immediately without guessing.
