Bolt stretch can vary widely with just the difference in the lube used,oil,moly,grease,nothing.

Any reasonable torque wrench is fine for using on a bike,but there are better ways.

In my line of work,I measure bolt stretch everyday,so I might know something about it,maybe.....

It's so special,you'll need a $10.00 mic from Harbour Freight for some bolts.If you have blind holes you'll need gun drilled bolts and $10.00 depth gauge from Harbour Freight.Even this would be far more accurite than the best torque wrench.But all of this has nothing to do with bicycles....
