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!
 
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.
 
Just built a rear wheel with Circus Monkey hub.
I am really impressed with the quality for the price.
Wouldn't hesitate to use these again.
Only problem I had was the QR skewer fit really tight so I had to sand it down a bit.
Front wheel is next.
 
I'm racing on a pair of 28/32s laced to Major Toms.

So far, no problems. My wheel builder friend turned me on to the CM hubs. Happy to see cartridge bearings in there. Makes for very easy adjustment and maintenance/replacement.

Communication was responsive. 28/32 was not on their eBay storefront. I was told to order whatever I wanted and add a comment that I wanted 28/32. Hubs arrived after ~1 week.
 
In my first post here I noted no apparent lubricant in the freehub. A little light lithium grease and all was well.

Mine are now 18 months old - no problems.
 
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
Do you think dt swiss aerolite spokes will work in these hubs?
 
I´m building a set of 24+28 wheels with these hubs and a 390g rims.

I´m wondering what butted spokes would be the best... I´m planning on sapim 1.8-1.6-1.8 front and rear. what do you guys think? should i go for supercomp or competition on the rear drive side?

Thanks a lot.
