LHD + RHD setup = one day joke that terrified some local riders and bike shop staff. Extremly heavy with two 3/16" chains and shitty (non heat-treated)6mm thick steel sprockets. It was build based on ACS Southpawls 16t LHD frewheel imported from US. RHD used cheap Dicta/Liftu frewheel with lifespan of about 1 week.
3/16" chains fitted only 11t or bigger drivers. I used to run them with 24t (indestrucatble) steel sprocket for 24" wheels.
Anyway Im happy these heavy bastards are gone. They costed me more than proper bmx chains since I dammaged too many chain-tools.
510hx made by KMC or better PYC (e.g. Cult) it way better. Mushroomed pins, bla bla bla. Light and strong. Paired with perfectly round 7075 sprockets and proper chainline ---> WIN. No more broken chains (except few times a year ha ha ha).
btw.. today I ate concrete shit when my connecting link of 510hx exploded (which does not happen to often...). Hopefully I was TWO pedal strokes from local bike shop and they had some 1/8" connecting links. Which usually I can find here only online. what a WIN.
