Hey,
have you ever thought about buying a bike in your local bike-shop?
You have had so many technical questions so far, that I would sugest NOT to buy a bike via internet.
It seems you are not really familiar with DIY regarding bikes.
So why did you buy via internet?
AND:
Why dou you even show this eMail. This is something confidential.
Not because of the suggestion, but because of privacy protection to the one you are talking to at Canyon.
Why do you think this is a stupid suggestion?
Did you try to do as suggested?
If its useles, why would Canyon suggest to do it?
Did you ever think about production tolerance?
Imho there are 5 parts that are bolted together just to hold the lower shockmount: left and right rockerarm, left and right Trackflip, shockmount.
Even if the spacer of the shock is just a tenth of a millimeter too wide, the result is play in the trackflip, I guess, because it can not sit tight in the Rockerarm anymore.
So please...:
Try as suggested. If this doesn't work, you are very welcome to come back here and ask again what could be done, AFTER you talked to canyon beforehand!
Thank you!
