      <p style=”text-align: center;”>Just got my new whip (2020 Genius 920 for anyone asking) and was pinpointing the usual creaks and clicks that happen when riding a bike for the first time. In doing so I noticed that one of the 10nm torque bolts would not come loose. I tried using as much force by hand as I was comfortable with because I know those things are sensitive and it would not budge. I really don’t want to deal with warranty’s and stuff right now, so if anyone has a good method of undoing stuck torque bolts without damaging the bike it would be much appreciated. Thanks, and stay healthy!</p>

      What the hell is a “torque bolt”?

      Torque bolt being the rear linkage bolts sensitive to force, measured in NM. That’s what all the shops and riders around me call it, so that’s what I say. If you know a different word for it, I’d be interested in hearing it

      Douse it in PB Blaster, tap it a few times, and let it sit for 5 – 10 minutes. Then put a star-bit/hex (whichever it uses) of the right size in a socket wrench, put a “cheater bar” (length of old pipe) over the handle, and crank it out. Clean all the PB Blaster off and grease it well before you put it back together. And torque it to spec this time.

      As I use many forms of fasteners daily, I had to ask. Every bolt I have ever used has a torque rating and therefore was confused by the terminology.

      There is a term known as torque to yield. That type of bolt will be immediately replaced with a standard grade 5 or 8 stud to eliminate the issue of failure. These are guaranteed to fail if not torqued to a specific value, then torqued in one or two 90° increments. These are said to not be reusable and are typically replaced.

      Of the many full squish frames I have fabbed over the years, the suspension pivot bolts are pivot bolts, the rocker bolts are rocker bolts.

      What ZipHead posted should get you back on track, lest the bolts were loaded with locktite or similar. That may require some heat to do the deed.

      Good luck, gitter dun!
