I got myself the skewer and rear wheel pinhead upgrade- I installed them very quickly. The RR2 sizes are:
Rear nuts order 12mm
Front skewer lock - 168mm
Replaced my quilt release with a bolt. I?m ok with the stock seat.
Discount code: DEC2022 got me 25% off.
I am not guessing: I did it. Radrunner 2 sizes only.
