I'm getting a fork modified with some braze-ons (to take a rando-bag rack, post-mounted centerpull brakes, and low-rider rack).

In this thread I am asking about locations for low-rider braze-ons. For maximum compatibility, it looks like I need:
a) an eyelet in front of the dropout (my fork already has fender-stay eyelet behind the dropout)
b) a mid-fork eyelet (I'll probably have this on the middle of the blade or the back, so it doesn't interfere with the mid-fork eyelet to support a handlebar bag randonneur rack)

There are numerous low-rider rack designs; are most designs sensitive to precise relative locations of the two mounting points, or is there a fair bit of adjustment so the fork-based mounting points can have some variability and racks will still work? My fork has a bit more offset than typical steel forks.


I have one other question. I appreciate the suspension that steel fork blades can provide on a rim-brake bike (disc brake requires the fork blades be more rigid). I'd guess that most low rider racks make the ride more rigid by connecting the dropout to the middle of the fork blade area. Are there any low-rider designs that allow the end of the fork blades to flex more?
