I didn’t want to post this thread with the brand name in the title for concerns over how it might effect the manufacturer, BUT, I feel like I have a certain responsibility to report recurrent problems I have had with the new style KH hubs.
I spent this past weekend rebuilding two wheelsets, both of which were built with the new KH hub, these are the hubs with the faux carbon body. One had been “fixed” with the addition of two split pins that were pressed through the hub body and spindle, the other was unmodified.
As I understand it, the tolerances between the hub body and the spindle are not tight enough, such that the epoxy that holds the hub and spindle together will weaken with use, then they creak, squeak, etc…until ultimately they fail entirely.
KH products have a one year warranty, so one of my hubs is outside the warranty so I will receve nothing. The other hub replaced a broken Ti hub (the original welded style) which UDC graciously provided when KH would not replace the hub due to it being outside the warranty period. I had the Ti hub sixteen months and it cost $400.
My concern stems from number of hubs that have failed (3) and the lack of an extended warranty to cover failures that result from poor design/poor manufacturing, esp when these failures are known. I am not an extreme rider by any stretch, I don’t do big drops and I don’t hop, so it is not my use that is causing these failures.
I appreciate the involvement of Kris on this forum and his efforts to advance unicycling, however, at a cost of $600 cash for three hubs and ten hours of my time unbuilding and rebuilding three wheels, I am more or less over it.
If you have a wheel that is built with a KH hub and it is making noise, don’t assume it’s the cranks or spokes. Before you exceed the manufacturers one year warranty, contact the store where you purchased the product and let them know you are having this problem, then document that you made this contact.
Kudos to UDC and Josh for making efforts to correct this problem. Hopefully it has been resolved in the most recent batch of hubs.
