off brand freehub?

my friend has a specialized comfort bike. the pawls in the freehub are not working, causing the crank to slip. i attempted to remove the freehub, but a 10mm hex wrench will not work. is this an off brand? how do i remove it?
thank you in advance

You may find this to be an 11mm hex rather than a 10mm hex.

If it is 11mm...with bolts on both sides...in a loose ball bearing hub...it'll be a generic from Formula, Chosen, Quando, etc. The Chosen's are available in both 7 and 8/9 speed.

You are talking about replacing the hub with a shimano I hope. The hub you are working is most likely a Joytech. If it is it takes two different size allen wrenches to remove the freehub body. http://www.novatec.com.tw/novatec/english/tec_r.php

As davidad said, I hope you are planning to replace the whole hub as a Shimano freehub body won't fit your current hub shell. You might find it cheaper to replace the entire wheel instead of doing just a hub swap. Any of the Shimano 8/9/10-speed freehubs will be fine as lond as the over locknut dimention matches. For a 135 mm OLD hub, a Deore or Deore LX will be great and for a 130 mm OLD, a Tiagra or 105 should fill the bill.

thank you
we took the axle out and there were 9 1/4 inch loose ball bearings on each side. i hope this clarifies what freehub this might be.

9 1/4" balls in a rear hub is common as mud, IIRC

i was hoping this would help identify the freehub. i called specialized customer service. the name joytech came up. he could not tell me changing to shimano would work.
thank you

You would have to replace the hub to be able to use a shimano freehub.
The Joytech takes a 12mm allen wrench in the hub side and a 7/16" allen wrench in the freehub body side to remove it. A friend has this hub and I had to use an Al. 24" pipe wrench for enoung leverage to get the thing off.

i bought my wife a specialized sirrus elite 2010. did i make a mistake? i certainly hope not. are the hubs joytech? it is becoming evident that specialized is using these cheap hubs. we have to rebuild the wheel with shimano fhrm30 8 speed hub. a lot of labor and maybe different lengh spokes on my friends bike.
thank you pothound

As long as you know how to work on them they are OK, not great but OK. I overhaul my friends every 2k miles.
If the hub has the right side bearings inboard as are found on some of the joytech hubs I would replace it. The axle is overstressed.
