the height you want the mudguards to sit in relation to your tire , clearance between the tire and
the mudguard . is a choice..

you dont have to have them as close as possible do you?

if you can set up with more clearance then width compromises become less of an issue..


and [+1] given the water will tend to be coming off the center of the tire , its largest diameter,
they really dont Have to be so wraparound..
