Enough with the sugarcoating - let's get real about derailleur cleanliness. You asked about the actual impact of neglecting to clean your rear derailleur, and I'll cut to the chase: it's not just about being fastidious. Over time, a grimy derailleur can lead to sluggish shifting and unnecessary drivetrain stress, potentially causing accelerated wear and even failure. Sure, there may not be hard data to back this up, but think about it - would you rather clean your bike or deal with a costly repair?
Now, when does "acceptably dirty" become "concerningly grimy"? It's a bit of a judgment call, but if your post-ride wipe-down turns into a full-blown scrub-down, you've probably crossed the line. And don't even think about using harsh chemicals to clean your bike - avoid anything not recommended by the manufacturer. A good rule of thumb is, if it can dissolve a penny, it's too harsh for your bike. So, no, nuclear waste is not an option for derailleur cleaning.
So, is this all just cycling lore passed down from one enthusiast to another? Maybe. But when it comes to maintaining my ride, I'd rather err on the side of caution. After all, an ounce of prevention is worth a pound of derailleur repairs, right? Now, let's keep this conversation going - what's your take on the time factor in post-ride maintenance? How long should we ideally spend cleaning our derailleurs? I'm all ears - or eyes, I guess, since this is a text conversation. Happy riding!
