Mine needed a bit of grease on the freehub prawls but after that they have been fine. They roll nice, are very light and are muy cheap. Wish they came in black or silver though, hate orange.

 

they are good, the guys on WW love them

a friend of mine has built some up with open pro ceramics for winter

 

I now have about 500k on a wheelset with these hubs. seem simple and well made. no issues so far. as with roadie I thought the freehub a little loud. these pull apart and the pawls were dry. so a little lithium grease and all is well. I really bought them for the colour to match my eddy AX orange theme.

 

Thanks for the replies. These seem like a great deal!

 

24/28 road

Just ordered a set of road 24/28H for some 38mm carbon cross tubs. Weren't listed on ebay so I sent them a message and they made a one item listing for me.

Thought that might be useful for the guys that need a bit stronger wheel than a 20/24H

 

how is the hub flange spacing? are they wider than american classic hubs?

 

There are lots of different lightweight hubsets being sold direct from Taiwan on Ebay. I ended up buying direct from a supplier for my build and have started selling them myself for a little less than the going price on Ebay. Mine are also about 16 grams lighter, not that that makes too much of a difference, and have six pawls, not three.

are they easily dismantled? can the axle come out easily? can end cap play be adjusted?
bought a carbon wheelset and none of the above is true. Not buying another wheelset where I can't take the hubs apart myself.

 

They are easy to pull apart by hand. There is no adjustment on sealed bearings which these have.

Lots more km now. no problems.

 

I have not dismantled the hubs I bought, but a mechanic who bought a set from me did and said that they "looked very good." I think they're very similar in quality to Circus Monkey, Dixie, and any number of CNC lightweight road hubs you'll find on Ebay.

 

Getting ready to build these onto some ebay 38mm carbon tubs with 2x black Revo's.
1220g according to DT's calc. Was looking at CX-Rays and Aerolites but decided it was silly to spend so much on what are some pretty budget wheels otherwise. That the Revo's are just about as light, easier to build and a fraction of the cost is a no brainer. They're for cross and I'm about 170lbs. Hoping they'll provide a nice balance between stiffness, compliance and fatigue life. They'll end up costing me about $430 so no big deal if they turn out wonky. $430! Just blows me away how inexpensive these things are. A lighter rider could run the 20/24, radial fronts/ND and end up in the 1100g range for under $400.

A few observations:

- 2x FHB bearings are 6902, 2x hub body bearings are 6802
- Front hub bearings had a tiny rough spot and a healthy amount of seal drag. No surprise considering the hub is only like $45.
- Machining quality is good
- Steel insert for axle stubs is a nice touch for those with Ti frames.
- FHB is shotpeened before anodizing. Nice touch to offset the embrittlement that ano does.
- O-ring's on axles help keep moisture out.
- As others mentioned, the FHB pawls need a tad more synthetic grease than they ship with
- Outside of flanges canted inward a few ° which helps spread spoke load over greater area instead of concentrating it at tip of flange

My hub measurements for the road hubs:

Rear, 28H 225g
38.0 ND ctr to flange
17.0 DS ctr to flange
47.0 DS flange dia
38.5 ND flange dia
3.0 spoke hole, looks like old style aero spokes might fit
3.0 flange thickness, radial head in with CX-rays OK as they need a thick flange when run that way

Front, 24H 80g
32.5 ctr to flange
32.0 flange dia
3.0 spoke hole
3.0 flange thickness

Use these measurements only for reference. Don't blame me if they are off by a bit or you order the wrong spokes!

Do you think dt swiss aerolite spokes will work in these hubs?

 

Regarding the Circus Monkey hubs, are those the published specs or are those your measurements? I ask because I have recently purchased a set of "Moyon" hubs that look identical (to me) to the CM hubs, but the specs I was given are a bit different than what you published, so was just curious.

 

My set ended up at 1185g w/o QR's. Not tensioned yet as I'm waiting for dishing tool to arrive.
24/28H
DT Revo, 14mm Sapim alloy black ano nipple all 2x
I'm about 175# right now. Will run these with 32mm Tufo Flexus Primus in frequently hardpack with embedded rocks or grassy/bumpy SoCal courses.

 

K, Sbh

I'll bite - what brand do you sell, how much and any pics? I need a pair of mountain hubs for a city bike project.

 

bumping from the dead. Looking on fleebay but most of the monkey hubs are offered w/ 20 hole front and 24 hole rear, building this wheel for my wife so just curious if i should keep looking for 24 front and 28 rear

send ebay message to seller or contact through site for them. That's what I did.

thanks emilio!

 

Lol...everything is so...orange!

I'm thinking of building an 88mm rear wheel just for the heck of it.

 

Lee, i was telling randy that i'm building up my wife a nice light wheelset for cheap now after reading all this stuff should be good. Well i'll just get the parts and have someone competent to build it...

 

Let me know what parts you end up getting. I want to get a 24h 88mm rim and build it up.

 

I'm building up a pair 32/32 in black w/Velocity A23s and Sapim db spokes right now. One wheel laced, lacing the other tomorrow. At the time I ordered they had silver too. They are smooth, and light!

You'll find the hub dimensions in this post courtesy of Lectron.

 

Another option is BikeHubStore.com. Basically the same thing as the CircusMonkey hubs, but are sold from US (imported from Tiwan I believe). And I believe price is better as well.

 

I built up a set of wheels using the Circus Monkey hubs. Have maybe 200 miles on them so far. I was adjusting the rd tonight when I noticed that the rear wheel would not freewheel, but rather, the rear wheel turned the cranks (when going forward).

Any ideas as to the cause?

Are there any instructions for disassembling these hubs?

-- Thanks!

 

I discovered its not very complicated - grab the aluminum end caps and pull!

 

Pulled off the end caps, removed the part with the pawls and the axle. Wiped everything down, regreased and reassembled. Seems ok now. Here is the interesting part. I rode the other day on some wet pavement (was misting out very lightly) and now the rear hub gets wonky??

Can someone explain this - is this just a cheap hub or am I doing something wrong?

-- Thanks.

 

These hubs are great, there is a guy in Spain who has sold over 60 wheelsets with these hubs.

Now the problems are:
-freewheel comes with very little grease or with now grease, so just when you get them, open them and put enough shimano thick grease or similar.

-2nd issue, and this one is a bit more un-known; included berings are low quality, they get rusted or oxided with water, when riding on wet weather or cleaning the bike. BUT, you can find easily decent bearings on fleabay, stainless bearings, with blue seals, for about 7$ each bering, and problem solved, you get a great hubset for a great price.

I will get mine soon, gonna order a bearings kit also.
