In order to fit both front and back panniers onto a mountain bike (rockhopper) so that my heel doesnt get caught on the pack panniers, what kind of distance do I need between wheels? i.e. is there a simple measurement that I can take on 26" wheels between the front of the back wheel and the back of the front wheel?

 does this even make sense?

thanks a lot John - hmm, size 11's and I think mine is a 425mm chainstay. what are my chances? can you get some panniers that sit further back than others?

I have size 14 feet, use Old Man Mountain rack, Ortleib panniers (back as far as they'll go), my heels clear on the various MTBs I've used. Only way is to suck it and see.

The bike on Sunday.

Grant's whisky?

How uncivilised.
