Another Broken Axle

[bikebloke]

Here is a video to show what it's doing. In sitting on the bike holding both brakes and pedaling with the left leg - the crack is parallel with the floor, and i'm in a seated position:

TITAN is coming to pick up the bike from me, after I gave them a mail. Thank you "bikebloke" I went to that link and mailed them.

 

they are a good company and back up their gear ,never the less , don't accept anything back you aren't 100% satisfied with as a consumer you have that right .......good luck

Looks like bearing movement to me - might be an optical illusion, but I suspect that hub has an issue

Definitely, something looks wrong with that hub

I just want to post an update. This will also serve as a "Answer" or "Solution" 

 

As it turns out the issue seemed to have been related to the freewheel and it's hub. Since the 7 speed cog/and freewheel/hub combo is a lot weaker, TITAN replaced it with a cassette and new hubs along with a new real wheel.

 

So for anyone else that runs into this. The traditional freewheel style is actually meant for the 5 speed type bikes. But as soon as you add more gears - the weaker grip becomes at the bearings, and this creates that flex, and what follows will be a bent axle.

 

I've sent TITAN a mail back with my appreciation for their efforts. They've collected/and dropped of my bike at no cost.

cool and well done Titan

 

always good when a vendor steps up and goes a bit beyond

Glad you got sorted but I still don't agree with the explanation they gave. I have NEVER seen a hub/rear frame flex like that and to be honest, I suspect a part or two ( such as a spacer, sleeve, lockwasher) was missing from the hub that broke twice.

 

Hope the new hub sorts the issue.

If it's a spin-on I can see how that would happen - there's no support between the outboard hub bearing and the frame, which is quite a distance. *** design, and one of the reasons manufacturers moved to the freehub system.
