this is how its planned
because its 42g "heavy" and thats with the maggie braze-on on the pic, imo the only lighter thing is a spoke tensioner
edit:its exactly half the weight of the heatsink,haha!
as said above,to stay variable in options,like say going to 22:17 in gearing,if i dont like it and want the rear brake aligned the same way//same chainstay lenght when going back to 22:16,its no problem.at the second my chain always has slack points due to chainwheel wearing unevenly from pedal kicks,wich i dont like as well
