they just totally destroyed the wrench flats. I'm assuming they tightened when they meant to loosen, but a pedal wrench should be able to handle that. The Park wrenches couldn't. My conclusion is that the wrench is just barely adequate. I know I have ended up hitting a pedal wrench with a hammer because someone over-torqued. No damage to the flats.

They probably didn't know the thread direction on the NDS.

Engineers....

+1 on this, I’m pretty sure 99% of people are over tightening pedals. They really don’t need to be very tight at all unless you want to make them impossible to remove later.

has always kept my pedals attached to the bike.

Pedals get tighter with use due to precession torque. There's a reason that the left pedal is left threaded - if it wasn't, it would have a tendency to loosen with use. Precession torque is also the reason that threads on BSA/ISO right side BB cups are left threaded (and why right side BB cups on Italian BBs, which are right threaded, have a tendency to loosen with use).

So, it as altogether possible that pedals are tighter when you go to remove them then when they were intially installed.


(If you were ever to disassemble a Shimano freehub body, you'd find that the bearing cup that holds it together is also left threaded - so that precession forces don't try to unscrew it as you ride.)

Watch where you stand...my worst bike injury from standing on a “lever” to undue a stuck pedal!

They sell it in a handy socket/ratchet group that also has a lot of other helpful tools. See link for details. https://pedros.com/products/tools/ge...it-socket-set/

More carbon does not make stiffer steel. Maybe higher yield/UTS, but definitely not stiffer.

I’ve worked with a lot of mechanics in the last 25 years. The best mechanics always have the most mismatched, cheap tools... Craftsman gets it done... and the worst mechanics have $100k in Snap-on gear but strip out an oil drain plug (true story).
