Helpful and professional. I took my Trek Domane in as I needed assistance with the seat stem, I was served by Chris (I think I have the right name) who immediately demonstrated that he knew exactly what he was talking about, as he identified the potential issue and noticed a few tweaks that are needed. I was given a time frame for when the would work be completed and left it with them. I was contacted 2 days early and when I picked up the bike Jon took the time to explain everything that they did with some useful tips. I would definitely recommend Trek MK to anyone. Thanks again.
