this is an update -
the top of my mount cracked (see photo). I tried emailing the trek store where I bought it, no response. I went to a local trek store to inquire and they said it wouldn’t be under warranty. I bought the bike 5 weeks ago. The guy gave me a piece of Velcro to hold my phone on. Velcro. For a 5 week old bike. When I asked about switching it for the mount with a case he said he’d never heard of it. Who are these people that the shops hire? I have to say, with all honesty, after $4k for this bike and the problems I’ve had with trek, it will be my last purchase with them. I’ll graduate to a better brand.
