loctite on pedal thread

[screenman]

Most experts use a torque wrench on lots of parts on the bike.

...... the wrench was dodgy much un known to us and it sheared one of the bolts!.....

Most head bolts are single use, designed to stretch. They often fail if you attempt to re-use them. So before blaming the torque wrench, were these new bolts?

Last time I put pedals on, I tightened them up finger tight, then put a spanner on and nipped them a little more. Job done.

think so but will check
my dad has rebuilt too many motorbike and car engines in his youth so i will ask him if he used new bolts and if he has heard about this

I don't, never have, I put a spanner on and if it feels tight enough.............that's it, its a bicycle not a motorbike that needs nuts n bolts torqued to certain torques, too tight and the metals strips on bikes, hand can feel if its right

I said experts.

leaving aside carbon fibre, what fasteners on a bike are critical enough to need to worry unduly?
i'm assuming a modicum of mechanical "feel" here, as obviously you'd not want gorilla strength nor the opposite, but really?

 

[young Ed]

on a push bike i just go by judgement

apart from the pedals which i reckon might be due to bearings i haven't had a problem so far?
i know many like to use a torque wrench on the stem where it clamps the bars but i really see no need for this!

Torque wrench.............never here, just feel. if its tight and feels tight that's enough, any more strips the fine small threads

Like I said experts use a torque wrench.

 

[Profpointy]

Like I said experts use a torque wrench.

why?

 

[mk6golf]

I can't think I've had a pedal come loose on any bikes I've had. I had one actually snap which was an "interesting" situation lol!

 

[mickle]

Like I said experts use a torque wrench.

Keep repeating it, doesn't make it truer.

 

[screenman]

why?

Because they know you cannot guess a torque.
