So this would or would not work with an already lowered bike either flip or nones? I would be willing to try this on one of my bikes as well.
Right, if you added the kit to an already lowered bike. The kit will take the fender down another inch and a half or so over your tire (which is already up into your fender if the bike is lowered) so you would likely run into tire-fender clearance problems at that point.
The offsets on the brackets and spacers are machined for a set amount of lowering of the fender. It bolts into place rigidly at that amount. Not a varying adjustable thing. You get the amount of change that the picture shows, lowered or not, unless I modified the NC programs for it to be a different offset amount.
hope that helps answer it. do you have a bike that's not lowered?
