Facebook Twitter LinkedIn Pinterest Bluesky Threads I argued with a bike shop tech who I let adjust my rear derailleur and I said that I thought the pinch bolt was installed upside down. He said it was not and that is properly installed. Was he right or am I right? by -curautvaleas Bicycling Bike Bike Repair Biking Cycling Repair

Makes it look sleeker.
flimflam_machine on February 14, 2025 9:59 pm What do you mean “upside down”? Do you mean that the cable should be on the near side of it?
BarkleEngine on February 14, 2025 9:59 pm What is a pinch bolt? And how does a bolt get installed “upside down”? Looks fine to me.
