Nice thread! So, I started biking in 92 and since pupils don't have cash for workshop repairs, I was thrown into wrenching the same moment I began and never stopped. These days I am totally guilty of wrenchers' cockiness, yeah got it all covered, noone can tell me anything. Last fall I got a Slash gen6, the one with the chain tourism, so to speak, idler pulley and additional pulley at the chain guide. From the start, the drivetrain made a slight churning sound, which disappeared when lubing the chain. Instant jump to conclusion: yeah, must be the complicated chain...
