attached on this one is a picture of the hanger to help explain the frame problem.
on the top of the hanger there is threaded hole. A bolt goes through the frame and into the hanger from the top. That wee tab sticking out the top of the hanger goes into a pre drilled hold in the frame.
Without the wee tab, the hanger will turn 360 degree on the bolt that attaches it to the frame.
So.. this wee tab goes into the frame at a specified angle. That angle is the optimum angle to ensure you mech is hanging in the correct position to work.
Torque Canyon Hanger
Now... several bike brands ( large and small) use this type of hanger system. Its does the job fine if the hole is correct.
To show you the problem that occurs when it is incorrect its best to show you pictures using a hanger straightening tool attached to the hanger.
Here is the tool on the bottom of the rim. All is fine. Its where it should be.

Here is the tool at a 90 degree angle. Its around 35mm out from where it should be!!!

This was the first frame/bike. The 2nd frame/bike had a discrepancy on the tool of around 20mm.
Now anyone who has bent a hanger knows how annoying it gets when your mech is a mere 5mm out of whack. Imagine 35mm.
The first bike was unable to work at all. The chain could not stay on any gears. The 2nd could at least keep the chain on the cassette a little.
And... due to the design of hangers being that they are sacrificial in the event of a fall. If you attempt to "straighten" the hanger. By that I mean bend the perfectly correct hanger to suit the incorrect hole, the wee tab breaks off and you need a new hanger.
You can attempt to straighten the hanger a little if the hole is slightly incorrect. But in the case of both these frames, attempting to mend it 20-35mm would result in the hanger tab shearing off.
This is Canyons response yesterday after I advised them I was going to put this information online. They finally gave me a real apology and some explanations.
We have ordered a replacement frame to swap the frame as in minor cases it can indeed happen that due to a welding process, a misalignment can occure - this was there explanation for the hole being in wrong place.
But then further in same email they put this which they blame it on hanger. Now that rubbish. As they sent alternative hangers indivdually which arrive undamaged in bubblewrap and they made not an iota of a difference.
you describe it as a faulty production process of all of our Torque frames? We have a database where we gather warranty cases since 7 years. We have a very god and detailed picture about common failures, weak spots, etc. The fact that the gear hanger bended, has nothing to do with a faulty frame. The gear hanger is a sacrifical part and designed to break in case of outer impact or to much tension on the drive system. During transport,
it can happen that the gear hanger gets bended, this is something we cannot exclude happening.
So... you have all the information to make up your own mind guys! This is just my experience with Canyon.
I've got real life stuff to do shortly! But I will try and come back tonight and see if anyone has any questions about these pictures.
