So bought a brand spanking new KHS Flite last week, i rode it a couple times up and down the street and had the rear cog slip slightly, so i tightened the lock ring some more, really tight and kept riding, last night it completely unwound and popped off both the lock ring and cog as i was riding down a hill. i’ve only ridden it about a 2km all up.
it appears a heap of the thread has been stripped, there is metal flakes everywhere. It doesn’t look that bad as both the cog and lock ring still screw on and off so it may have just taken the tops of the threads. does anyone know whats happened to cause this? the lock ring was tight? everything seemed good, so did i miss something? or should i be calling the shop and asking for help?
I bought it in a box from the a distributor sale, the wheel was all assembled, but was told to tighten the lock ring before riding, so i did exactly that. I just called them and they tried to palm it off to a bike shop and told me i should have tightened it more. They’ve got the warranty guy giving me a call soon, so hopefully i can get it resolved.
Sounds like you might be up a certain creek. If you didn’t get a workshop to put the bike together, you can hardly expect them to cover your wheel for free. You might get lucky and they could swap it for you out of the love deep in their heart, but otherwise you will have to prove that the product was unfit for purpose or faulty.
