New Boardman Team Carbon - set up is a mix of Tiagra and FSA; front mech didn't move to the big ring at all at first, Cycle Republic adjusted it and it worked fine, then started slipping, as in taking a few rotations to actually go on to the big ring and sometimes not at all. Now it's back to not moving...I'm sure I can YouTube an adjustment vid myself but just curious if you think it's worth taking back to the store.
