OK tried to find these hubs here in the states with not much luck. BTI does not have them in catalog, comes up empty in google search except for a few English web stores that seem to not ship to the states. Put e-mail out to chainreaction who does not carry these halo hubs. I would like to build a wheelset using these since the spindoctors I been running have been pita free for two years now. Anyone got a clue who I maybe missing or where I can find these. Halo has not answered my e-mails so hoping they will soon.

Hi There,

As far as I know BTI do not carry this hub as a stock item. I have sent your this page over to BTI for you to see what they can do. Failing that, you could try billys.co.uk who will ship world-wide. (obviously with carriage).

Sorry for the lack of response on the emails.

Pat (from Halo)

Has anyone got any ride time on Halo XCS or XCD hubs? What is their reputation for reliability?

They seem fairly new on the market and I haven't been able to dig up much in terms of reviews. I'm not that familiar with Halo hubs but the XCS looks like it has some decent features at a good price.

I just ordered a set of Halo hubs from BTi. Got an XCD front and XCS rear. I'll share more once I get them.

Anyone know the flange measurements of the XCS hub for spoke length calculation?

This is the XCD front hub with the end caps removed. Bearings are very smooth rolling and pretty big. The hub is pretty simple. My only gripe is that the 15QR caps have nothing that hold them in place other than the axle. So when the wheel isn't in the fork the caps will fall off easily. The QR caps are firmly held in place and I needed a QR to remove them.
The spoke holes on both the front and the rear seem large enough to fit Alpine III if you wanted. I was able to pass an Aerolite bladed spoke easily through the flange.


Six pawl free hub. Once the axle cap is removed, the free hub easily slides off. Everything is held in place with O-rings. There is no adjustment of anything.


Most web sites list this as six pawl and 48POE but that is really kind of mis-informative. With the hub apart you can see (hard to tell in the picture) it's actually 24POE and while there are six pawls, the way it works is that at any given time three of those pawls are engaged. So there are 24POE and two sets of 3 pawls that alternately engage. Interesting system IMO. The internal threading on the axle is for the M10 bolt on option.


XCS - weight of bolt on with M10 bolts. 385g 334g without the M10 bolts.


XCD - weight of 15QR. 138g. Front hub is pretty low weight.


XCS - weight of QR. 334g. The weight is the same as the bolt on without the bolts. 10g heavier than the claimed 325g.


XCD - weight of QR. 148g. Right there at the claimed 150g. The QR caps are heavier than the 15QR as they slide into the hub and hold themselves in place. The 15QR caps sit in place. If you were changing a flat on the trail you have to be careful with the 15QR caps because they will just fall off. I'm guessing that is the result of the search for light weight.

I'm lacing these to Velocity P35s with DT Super Comp spokes. Wheels should weigh in at the 2000g mark. Not bad for P35s. I weighed them at 604g and 602g.

The hub may have 24 slots for the pawls but if you count the number of engagements by rotating the freehub body I bet you'll find that it really does have 48 points of engagement.

As I predicted, the front wheel is a complete pain to install as 15QR. The end caps just fall off as nothing holds them in place but the axle.

It does. The way it's presented though people may think that all 6 pawls are engaged at the same time in 6 of 48 points. That isn't true. There are 3 engaged at any given time.

Though if you turn it one full rotation it does have 48 points, though its really two sets of 24 because there are only 24 actual points.

Most hubs are like that where the pawls are offset so only half engage at any given time. Hope, Industry Nine...

I would rather it be this way than have all pawls engaged at the same time with the same number of engagement points. This is because the ratchets in the hub can be deeper and much stronger if they don't have to squeeze as many into the ring.

I'm thinking that this is a big reason why the Industry Nine pawls have three spikes in them, so they won't skip since the ratchet steps are so small. Ever heard of any problems with a Hope freehub mechanism? I haven't... it's simple and the steps are big. In fact, this Halo XCS is the same design just with 2 more pawls, or one more engaged at a time.

Thanks for biting the bullet with these and opening them up to take pictures!!

I'd imagine the Halo XCS is fairly loud, thoughts?

How does everything spin on the rear? Any substantially weird drag in the axle or freehub body?

It looks like the axle would have a larger diameter step in between the bearings making removal/replacement very easy. Is this true?

Does the metal cap on the NDS contact any of the hub shell? Or does it just butt up against the inner bearing race and sit very close to the edge of the hub shell?

Thanks! Definitely looking forward to my tax return check, this seems like the hub for me... (ESP wBTI's pricing!!!)

It's built and has been on the trail. They roll great. Not super loud either; not nearly as loud as a Hope hub. No drag in the rear. It's like a regular free hub, nothing like a King.

The front axle inner diameter is the same as the bearing with a little notch to remove the bearing. The caps for QR slide into the hub but the 15QR ones just butt up against the bearing and work like a spacer on both sides. The 15QR axle is what supports the wheel.

I'll try to take a little video or something of the noise.

Can you measure the freehub body for me? Is it possible to stack a few cogs on there?
I'm wanting to build up a singlespeed hub with 5 aluminum cogs from an old 8speed cassette. I'll be using 10speed spacing with the new Saint Shadow Plus rear derailleur on my dirt jumper.

I don't have a micrometer handy but just for giggles I tried to fit some cogs on it and it fits 5 9sp cogs and spacers fine. You might be able to get 5 8sp cogs too. I have 9 and 10 speed cassettes but no 8sp.

GTR-33, would you be willing to provide a 7-month review update on the Halo XCS hub? Bearing quality? Freehub strength? Any external spline gouging?

Just found out about this hub... am also wondering about a review for it as it looks like a perect alternative to a hope trials hub. If you use a wide base cog/ sprocket than the al body shouldn't matter too much, considering if it lasts you even half as long as the hope your ahead of the game.... And depending on the bearings and overall quality of the hub it may be worth it.....
