Dahon Kenitix Neutron Front Hub problem
Update and correction.
The 2.3cm bearing tube is forced fit to the end cap not the bearing. There is a stopper inside the hub body which should prevent the bearing tube from slide out of the end cap. However, there is a gap of 0.7 to 0.8cm which allowing this sliding. Design error?? So what I do is cut a piece of tin foil of 0.7cm, rap around the skewer. Do this for both sides.
I will update in a few months if this does the trick.
The 2.3cm bearing tube which have a force fit on the cartridge bearing started to slide into the hub body after about 1 year of use. When this happens the aluminum end cap rub the hub body. I have discovered it early enough so I just use a vise to press it back. A week later, the tube got loose again. I reversed the end ( for a titter fit) and press it back.
There is a tube inside the hub body that should keep this from happening but it is not working. The tub is too large (I think). It should be the same size.
Possible fix that I will try next is use a puncher to enlarge the bearing tube. This should give it a tighter fit and keep it from sliding.
I found on the web one site which sells the kenitix neutron hub, http://airportshop.com/bikes/neutron_front_hub.html
It cost 94 USD. I am tempted to use an older regular bearing hub. I don't mind a little more weigh but more reliable hub. Does any one have one for sale? 74 to 75mm OLD, 28H, black preferred.
It is possible that I do wheelly and often land harshly to cause it to fail early?
