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 twentieth episode explaining the ins and outs of your bike's chain line.
Chain line isn't something that I'd call a must-know, but with Boost spacing and all sorts of stock and homebrew single chainring setups out there, knowing why chain line matters can save you a load of trouble. Not only that, a bike with a poor chain line will run rough, suffer from premature wear, and possibly give you all sorts of headaches when things get dirty. Calvin is here to explain how to figure it all out.
Stay tuned for more mechanical how-to videos with Calvin returning on the last Thursday of every month to show you the easiest way to get the job done. Want to know more? Park Tool's how-to section has you and your bike covered.
