Tech Talks Presented by Park Tool

Tech Talks Presented by Park Tool is a monthly video series hosted by Park Tool's own wrench whisperer, Calvin Jones. The series covers the A to Zs of some of the most prevalent repair jobs, with the fourteenth episode taking a closer look at some clever tricks when it comes to your bike's gearing.

Today's 1-by drivetrains can be set up for a massive range of rider abilities and terrain, but it takes some know-how to get things dialed in so your gearing best suit your needs. Calvin and Ben are here to help you with that by explaining the effects of different chain ring and cog sizes, and they even have graphs!

 I have a question. How do I make sure my derailleur cage is long enough to accommodate a range extender + chain elongation when suspension travels?

 One way: You can remove your rear shock and cycle the rear suspension by hand to check.

 @WaterBear: Trial and error is not a very ideal method is it? Especially when you order online and do the job yourself.

 @fastlaneflyer: From all the bicycle riding I've done, I've grown older, and smarter, and gone with, "fun, shitty, inefficient". I don't need a spaceship.

 Thanks for your comment and concern. Rest assured we don’t disregard perfectly good components here at Park Tool. For the sake of filming we often stage the misuse of components by using already old and broken components as stand ins for demonstration purposes. For this video Calvin was using the bin to make a visual statement about how others should commit to converting to a one by system. Like the old joke says, “throw it in the trash”. It was a video element used to illustrate that joke, but I see how you could have thought otherwise. Those components were immediately removed from the staged trash bin and put back on the Salsa bike. In fact, you will most likely see that same green bike with those components in several existing Park Tool videos and many more in the future. Thanks for your concern, sorry if you were offended.

 @ParkToolCompany: I got the sarcasm! I should have put "[PSA]" at the beginning of my comment. Being facetious is not easy to convey in text.

I have Chromecast and was watching the video on lubing wiper seals. I know that anodizing on stanchions is pretty hard and does not scratch easy. However, when Calvin put the metal probe between the seal and stanchion I said out loud "NO", in a worried voice; both my brother and Nephew thought I was talking to my nephew, but saw me staring at the TV. My brother asked me what was wrong and I just said, pointing at the screen, "no-one should do that!" Thought I was getting after the boy. My nephew looked at the paused screen and said "o'yeah, you do that with a zip-tie". He's 7, him saying that put a big smile on my face. It shows he's paying attention when he sits there as I work on our bikes!
