"Hi Martin
Thankyou for the e-mail.
I would agree in some part to the Liteville Engineer- we looked into the fitment of headsets to fully integrated headtubes and decided this would not be a good idea due to low insertion depth and differences between the sizes of integrated headtubes between manufacturers.
We looked into the Canyon bike on request of many owners as only the lower cup is integrated and being an oversize 52mm bearing there is 8mm allowable insertion depth for the cup to seat. Also being 52mm there is a much larger locating surface area than the smaller 41mm od integrated bearing headtubes - around 25% more. - Many standard headsets have a similar insertion depth (We have some from another manufacturer for a 56mm headtube here infact) and we dont hear or see any report of problems.
Before releasing the headset it was tested for a month in a testers bike, we have now been selling the Canyon headsets for around 3 months i believe, we have actually sold out of many sizes of the first batch - so the oldest headset has now at least 4 months riding on it.
I am not sure how the steerer tube of the fork could be damaged by the installation of this headset though - are we referring to the frames headtube?
As with all of our headsets - they alter the manufacturer intended headtube angle of your bicycle, as such the manufacturer of your frame may refuse warranty due to this modification (though we find more manufacturers are specifying anglesets or our product with no problem and reccomending their fitment) - we of course can offer no guarantee against potential frame damage as many factors come into play. We do stand by our products though and in 4 years we have had 2 headsets back for warranty due to manufacturer defect, which i will openly say was the OD of the headset being 0.05mm too small which slipped through QC. As background, i am a fully educated mechanical engineer with a BSC Degree in Mechanical Engineering and stand by the products we sell - which is the reason we have decided not to manufacture any other integrated headset solutions.
I think in short, the fear of this causing a problem could refer to smaller types of integrated headtube.
One manufacturer actually does make angle headsets for fully integrated headtubes, they have been doing so for quite some time and i assume no faults have been reported as of yet as they would have ceased production if so:

If you need any further info please let me know.
Thanks, regards, Rick

... haben die Nerves im Steuerrohr eigentlich die selben Wandstärken wie z.B. ein Tork?

. nicht sehr ermutigend, vielleicht haben sie die speziellen canyon-steuersätze noch gar nicht lagernd?
