Afternoon. A colleague has just taken delivery of a new bike for commuting to work. The rear disc rotor looks extremely tight to me (around 1-2 mm) and the chain stay is already scuffed from his efforts to fit the wheel. Looks too tight to me and I've advised him to contact the seller. I'm on my phone so am struggling to post the pics but have attached a link. Thoughts? Ta.

Aye,something not right*,get it back to the shop for them to check it out.
*from the little I can see in the photos.
That looks like too-big a rotor for the frame.
Looks fine to me to be honest.
Well I've tried several times to remove the rear wheel and it is impossible to do without it catching the chain stay so something is amiss. Had to put tape around the stay to prevent it causing further damage but it does now at least spin freely. It's a 160 rotor as per the bike spec.
Looks fine to me too, he just needs to be a bit less hamfisted putting the wheel in.
And it's a Planet X isn't it? So the response will be "oh well, nothing we can be arsed to do" anyway.
Looks okay to me. Does your friend have opposable thumbs.
Need to show you picture of disc side stay in my Plug3 😀
You will be amazed how much clearance your friend have and how little scuffing it caused.
Cheers!
I.
It's really hard to capture just how tight it is but I've had another go...
Owner is onto live chat with the supplier.
Well,in the interests of science* I just went and measured my rear disc and two other bikes in the works bike shed.
The discs are all more than 6mm clear of the chain stays and the spacers on the disc side of the axles all look longer than the one in the first photo.Now all of this may not matter if it spins free when in the dropout,but if it was marking the frame every time the wheel came out I wouldn't be happy.
* not really
Looking at how far forward those scratches are of the rotor, it looks like he's missed the dropout entirely more than once.
that does look tight. Presumably its a 135 spaced frame and wheel and the wheel appears centred in the frame correctly?

<span style="font-size: 0.8rem;">It wasn't initially which is why he asked me to take a look as it had clearly been rubbing in the frame either as it was fitted or whilst he was turning. Yes 135 spaced frame. Gravel bike. </span>
This forum is a nightmare on a phone these days!
Yes the wheel is now properly centred in the images I have shared.
For some similarly unscientific and no doubt irrelevant comparison I have checked the clearance on my own gravel bike (pinnacle Arkose) and I reckon I have at least 4 or 5mm more....
