Disc mounted pannier confusion

I have a standard rack on my disk brake commuter.  It took me ages to work out why I couldn't get the rear wheel back in after I'd taken it off - much struggling before I realised that the rack was a touch narrow and squeezed the rear triangle in a bit - just enough so that the wheel wouldn't go in.  I now have the knack of prising it open again to get the wheel in, before clamping it all up again with the skewer

As above use the same holes for both. Make sure that the rack mount is against the frame though, the more you put in between (washers, mudguard stays) the weaker it will be. A standard rack will probably work better there than a disk specific one.

I use rubber tap washers and a stainless washer between frame and eyelets for brackets. It provides protection, cushioning and pressure on the threads to resist undoing. You can also add thread lock

The disc specific racks tend to be slightly wider at the mounting points but beyond that, there isn't much material difference.

You can happily carry a fully laden non disc rack and a set of mudguards on one pair of bolts. Just slip some washers in between each interface and make sure everything is tight to properly spread and transfer the load.

My Boardman CX has been operating this way on commuter duty for three years. I've had all sorts of stuff on the back.

A quick check every few weeks or months is normally all you need do.

If in doubt, you could use a rack like this one: http://www.blackburndesign.com/en_eu/racks/rear-racks/ex-1-disc-rack.html

I've used that on my road bike, which doesn't have any rack mount holes.

You can also get a seat post clamp with built-in rack mount mount points if you don't have them on your frame - I didn't know that at the time and zip-tied it to the wishbone above the rear brake.

Do not mount them to your discs.

Sorry, didn't spot the picture link.

looks like you'll need to use P-clips. I guess you could risk using the mudguard mount, but I wouldn't as it won't be designed for the purpose...

Yep, what frame?  Looks a bit like a Canyon, which I don't think often have pannier mounts.

What frame?
