For The Attention of Bike Assemblers

When you install a cassette there really is no need to get some 25 stone porker to tighten the lock ring by forcing the wrench with all his might while three of his even heavier mates bounce on the end of a crowbar. Remember, some poor sod will want to remove it one day.

That's all.

Working on old bikes in community bike workshop one of our most useful tools is a one metre length of scaffolding for extra leverage over the handle of a spanner or wrench.

I have a 1.5m pole I use and it's fab, last week taking a bottom bracket out we where putting over 100kg of weight onto the end of the pole and only just eeking the BB out. Got there in the end. My physics is rusty but I calculated that at over 1500 nm of torque.

Ah! You don't want that coming loose when you are out on it !

Slightly off topic, but regarding lock rings on fixed gear hubs. They only ever need to be hand tightened. They will automatically tighten up if the main sprocket starts unwinding through severe back pedalling.

I hope that they put some thread lock on it just to be sure.

I had the same problem fitting different pedals to a new bike. Need a scaffolding pole to get the original ones off.

Same with thread on BBs, pedals and cassette lockrings.

I bl**dy well hurts if one comes off when standing on the pedals!

I can believe that but I have never had it happen to me. I just use reasonable force with the appropriate spanner but I do check the tension from time to time.

Are you saying that a hand-tightened cassette lockring will never loosen ?

When using a roadside cassette tool NBC2 on less than optimal horizontal dropouts, I would only tighten the lock ring to 3-4 clicks.
