Good morning,
I know very, very little about CF steerers so feel free to mock me.
I recently had a new Ribble delivered, the wheels were in place, the stem had been tightened to at least the minimum specified torque and the handle bars were intentionally not mounted onto the stem. All that was needed was to undo the front clamp on the stem, place the bars in the correct position and do up the front clamp.
But what would happen if I was an idiot at the factory and;
I have no idea how strong CF steerers are when subject to this kind of torque.
- Tightened or over tightened the pre-tensioner,
- Tightened or over tightened the stem onto the steerer,
- Clamped the bars into to stem
- Decided to rotate the bars so that they were parallel to the frame and not perpendicular and then unclamped the bars from the stem?
- This would probably required putting the front wheel between your legs and turning, as was not uncommon with quill stems and not fully undone expanders.
This explanation has the advantage of complying with Hanlon's razor - Never attribute to malice that which is adequately explained by stupidity
Bye
Ian
To me the breakage doesn't look like a torsional break but more of a clean snap caused by 2 ends being supported whilst pressure was applied to the centre of the stem. There is a strange line coming up from the fork crown which seems to suggest that something was pressing against it whilst pressure was applied from above.
I know that they sometimes test things to destruction for safety purposes but not on customers bikes!
I'm thinking the same. The response from the company when I rang them to explain that a badly damaged bike had been delivered was pretty poor - 'send us some photos and we'll take a look'. When I asked when they'd get back to me they said next week sometime as they're very busy! I expected a more helpful response and couldn't help thinking that they are just happy to hold onto my money for a while!
Where did you get it? A reputable U.K company wouldnt speak to someone like that because they would know the consequences.
If you have bought direct from China or from a private buyer then you have been scammed and you wont see your money again. How did you pay? If you paid by credit card you may be able to get some help.I'd take it up with the bank.
I'm very glad you got your money back and all is resolved. Do you think you'll try getting another bike from them, or are you done with them? Seems like they were honest about it all, I wouldn't be afraid to order from them another bike due to their fast and courteous service.
