Chasing after tenths of second = DIY swing shortening.
After long period of reflection, discussions with guys who already are on shorter swings I decided to go for it.
Connader is one of such advisers 😎.
I've to say, such thoughts born many years ago already, but somehow I was not brave enough to perform DIY short swing.
And so i decided to go for shortening only and relocation of brake and chain guide brackets to fit them with offset sprocket.
Swing space widening wasn't in schedule. According to my opinion this wont give any benefice excluding more space to don warmers. Anyway bottleneck to pull out wheel is gap between right swing arm and chain main bracket.
So, everything became dismantled and prepared for doing digimath.
