New cx bike, rubbing noise

Bought a Jamis Nova Race cx a bit more than 2 weeks ago in Bristol. The buying process had it's ups and downs. When I got to test ride the bike I heard a discrete rubbing noise coming from the lower/back part of the bike. Back in store they had a look at it but there was no noise when free spinning the wheels. I've been re-assured by the selling guy it's all normal, possibly coming from the rear wheel hub and it will improve in time. Front wheel rim was scratched in a number of places so they offered to change the front wheel in a few days.

Two days later returned to store as the intermittent rubbing noise was getting louder, they took it out for a ride and acknowledged the noise immediately. They advised me that in order to replace the front wheel they ordered the same type of bike and they would change the back wheel as well which should sort out the sound.

A week later had a phone call from a store staff member and told me the bike would take a long time to arrive (I believe they went out of stock, although just 2 days before I called them to inquire what's going on and they said the bike was on it's way...) and suggested a change with a different wheel-set (Mavic Aksium) which considering they have a decent reputation for reliability I agreed to, although I was not very happy to lose tubeless ready compatibility. 3-4 days later went back in store and had the wheel-set changed altogether. The second I free spinned the back wheel it was clearly touching something and stopping immediately. They re-adjusted it and after riding it a few meters the rubbing sound was back.... this time louder. I went back and forth with test-riding it and having brake pads distances re-adjusted for about 4 or 5 times that day. Sometimes the sound had a metallic character when it was stronger. There was no sound in store but it was coming back upon riding the bike. I'm not a big guy, about 12 stones. Eventually they managed to adjust it so that there was almost no sound on a short test ride. They said they would think about changing the brakes and contact me later. On my way back home I noticed again a discrete intermittent rubbing noise that was more prominent when going uphill (not necessarily on a steep hill). I've sent them an email straight away to inform them of this and that I would consider their suggestion of changing the breaks to a different model/manufacturer. Also now the braking pads are seated at about equal distance from the rotor (and to my eyes further away from it than initially), and as they are Avid BB7 I'm not sure if that's right as my understanding is that one pad should be seated fairly close to the rotor.

Now I'm 3 days down the line since emailing them and haven't heard anything back...

Do you think changing the brakes would help sort this issue? Anything else I could suggest them to try? I wouldn't want to change the bike as I like it, but on a new bike I wasn't expecting intermittent 'rubbing' sounds that are so difficult to sort out...

That metallic sound you describe sounds like it could be either a really poorly adjusted disk brake, or the rotor might be warped. Try adjusting the pads all the way out (it will make them useless, so dont go anywhere fast!) and see if it goes away.

Personally, I would return and reject it..I know you said you like it, but it's not a good start to your relationship with the bike!

You could even buy the same bike elsewhere, but would hopefully get one without all these issues

Ive bought 8 shop supplied bikes in the last 5yr
every one bar the Sensa bike from Merlins needed sorting dispite shop PDI..
brakes bars..pedal lose twice..no air in forks ...tyres flat..badly adjusted cables..over tight headsets..gears not indexed ..lots of basic stuff that just shows poor attension to detail.
sadly the shop pdi is usually a quick once over..
if you got the bike from Halfords or tesco it probably wont get you home.

im of the opinion if the shop cant do a PDI why trust them to fix it?
Diy or take it to someone who can

I bought a new Dawes last year and had a noise from the rear wheel, it was driving me crazy. Took it back to the shop and the owner clocked it straight away.
It was the rubber cone, dust cap thing on the near side of the spindle howling against the wheel. Drop of oil between the two, job done. He said it was very common and the cone would wear slightly and bed in, stopping the noise but the oil would help until then.

Threads like this make me despair.

You can't expect to bike shop to do the tiny adjustments that you ought to be able to do to keep the bike in trim. Look it up on YouTube and learn how to adust your bike. Disc brakes have tiny clearances and will rub when the frame flexes under effort if adjusted too close. You can't expect even the best mechanic to spot this with the bike on a stand. Learn to adjust it yourself and get the bike running perfectly.
