So, my new Merdia cylcocross bike has had a few runs with the same niggling issues.
Rubbing sounds from front and back discs Jumping out of gear at around 5/6/7. Almost constant sound of the chain rubbing or touching another gear when pedaling
I am sure the first is a set-up problem but am not sure about the gears.
I've only had it a week, 4 rides. 1 on byways and the rest on road. Less than 30 miles.
Assumption is to make an ass out of you and me.
Those who assume they know you, when they don't are just guessing.
Those who assume and insist they know are daft and in denial.
Those who assume, insist, and deny the truth are plain stupid.
Those who assume, insist, deny the truth and tell YOU they know you (when they don't) have an IQ in the range of 35-49.
Disc brake rub is pretty common and annoys me. Assuming you have Shimano components, the following video will hopefully get rid of it. I'm sure there is a SRAM one on YouTube if you need that:
From your gears jumping that is probably just an alignment issue of the rear derailleur against the cassette but could be something else. Try this
For chain rub it's normally the front derailleur by yours looks like a 1 x 11 so I'd be inclined to say it may need a good clean if the second video above doesn't fix it.

Let me know how you get on.

Thanks. It's brand new so it sounds as if it's not been set-up and road tested properly.
Looks as if I've a trip back to the shop.

It does sound like a set up issue. Slipping gears is a pain but is normally an alignment issue.
The disc breaks do rub especially if there is water or grit in them - I get a 'ting' sound from mine and it drives me mad.
GCN on youtube also do some good maintenance videos so might be worth a look.
Thanks
I've just called the store and they think it's just the cables bedding in. Annoying as they are in Bicester which is an hour each way! They knew the answer right away which is again reassuring.
Still, I like the bike but have no benchmark, which is probably good!
The bridleways around us are awesome so I'll not need a road bike.

Yep, that's what I'd do. The derailleur and gears should have been spot on when you got it. They will shift a bit in the first month or 2 of use, and you often need to have things readjusted within 3 months of reasonable use. That's normal and then it all settles down. But you shouldn't have rubbing breaks and skipping chain on first use.
It's fairly easy to sort out yourself (and well worth working out how to do it eventually), but for a new bike I'd just take it back if you can and ask them to adjust it.
You've just got a set up problem with the gears... I think this has already been covered by others... but you need to get familiar with the correct positioning and set up as you'll be taking a wheel off for a puncture for example.
Disc brakes... well they tend to collect dust and grit... in all honesty for most cycling needs they aren't as good as ye-olde fashioned brake blocks which are so much easier to adjust... but again the need aligning and checking on a regular basis.
That's why bikes are cheap from discount suppliers... they cut corners. IF you do get keen on 'upgrading' it might pay to use a 'proper bike store' like epic cycles.... or indeed a local bike store where they will take the time and trouble to set up properly, rather than send a bike in five parts in a box.

I was just about to say - that with most new bikes - a decent bike shop will get you to come back in after a couple of weeks for a "shakedown service". Cables stretch etc, and things settle down - new bikes always need a bit of an adjustment after a few rides

They will get a few words from me as to the set-up.
Thanks Swansea.

All things you'd expect after a year of heavy use, but it's clearly just not been set up properly. It should be perfect initially, then need a quick adjustment after roughly a month of riding as all the new cables and parts start to wear in and stretch.
