I just bought a 13" spitfire to build my daughter a bike. The frame has horizontal dropouts (10mm x 135) but I want to set it up as a 1x9.

I got a set of "tugs" with it so that she has no issues with the rear weel shiftin or moving.

My problem is that once I install the tugs putting the rear wheel back on is virtually impossible - ther is no easy way to fit the rotor into the caliper.

The stock picture from the fire-eye site shows basically what I'm dealing with:

Does anyone have any suggestions how I can overcome this issue? Any advice is appreciated.
