Diamondback rear hub problems.
Not looking for advice, but sharing a new learning experience.
Diamondback Overdrive 29er. Chinese but a good bike for me anyway.
On a ride I took it on last week, I thought it wasnt rolling as well as it should. I was whupped after that ride and I shouldnt have been. Checking rolling resistance, the front spun very smoothly, and the back almost as smooth, but I could move the wheel side to side and it made a clunking sound. Of course weird sounds have to be bad!
When I took the wheel off, the was the clunking sound of a loose part inside the hub. Never had that sound of thing in a bicycle hub before! After removing the axle the gear cluster fell off in my hand. Another new weird experience. Ahh now I get it. The part making all the clunking noise is supposed the be screwed into the cluster to hold it to the hub! It had come completely loose. You need a 12mm allen key to tighten it in case anyone finding this thread has the same problem. Well, where I was I didnt have a 12mm allen key, so I improvised. Two long 1/4" bolts threaded together end to end with a nut became the magic tool. A little blue loctite and its all back together to stay!
Anybody know what name or brand that hub is? I didnt find any markings on it.
Hope this helps someone else having a weird rear hub problem.

Maybe the freehub body wasn't installed tight enough to begin with, but 30 ft-lbs or so should keep it in place indefinitely without threadlocker.

HI. I bought a Diamondback 29er and had a problem with the front tire mechanism. The Quando hub dustcap was toast. Same sound you are referring to in your post. Do you happen to know of an alternative to that hub? As a newby, I am not sure how they are compared. Anyway, the quando hub needs replacing and I need to comparison shop.
Any ideas?

Might check LBS on a better wheel with a less cheap hub ..
A machine built wheel with hand finished truing at the local shop will be decent.
you can find Shimano Hub wheels , drop by the shop and ask .

What is of use to others is mostly that observation and getting your hands on the bike is what helped both of you identity the problem.
