FRIDAY TEASER

mistermatthew

It's the day before a big race, your new carbon handlebars have arrived and you are ready to fit them to your race machine. You read the manual and find out that they have to be tightened to a specified torque (5N) or they will break and you will die, and most importantly the race is gone.

Problem, your torque wrench is broken.

Using household items you fit your bars to the required torque (5N) and go claim that rainbow jersey.

How did you do it?

I use an allen key.

Plus some tape/string and whatever weights add up to 5kg.

Hang a pound of butter of a 1 metre bar!

Excuse imperial/metric mix, 1 pound is just shy of 0.5kg.

Acting over 1 metre is close to 5N.

0.5 * 9.81 * 1

Find a small child, around 4 to 5 years old and ask them to tighten your bars. I reckon 5 Nm with a 4mm hex is about what a small child would consider "tight".

If in doubt, stick with your current bars.

5NM is a max, not a target. Just tighten the bars until they no longer slip.

Move along, there's no teaser to see here.

His steerer tube snapped.

Guess I failed lol

Tighten it til you hear a crunch, then loosen it off half a turn...that's probably about 5Nm :pac:

I tighten it to exactly 5N using a paperclip, some rope lying around and the earth's magnetic field.

You could also use a fork, half a weetabix and a size 6 flipflop, works just as well!

The weetabix would crumble so you couldn't be certain of the force it exerts.

Jeez, how accurate do you need to be!

Anyway, the weetabix is just to replace the calories you'll have burned while tightening the bolt!
