Technique bars, and the load rating that matters
A technique bar weighs between 5kg and 10kg and is built so a beginner can rehearse the movement pattern at the correct bar height and with correct hand spacing. The good ones still have rotating sleeves, because a snatch without rotation teaches the wrong thing.
The number to read is the load rating, and it is low. Strength Shop’s aluminium technique bar is rated to a 20kg load. That is not a bar you progress on — it is a bar you learn on, and then you move to a full bar.
Why a 6ft bar is not just a shorter 7ft bar
The useful 6ft bars keep the centre section at the full 131cm, so the bar still sits properly in a standard power rack, and take the length out of the sleeves instead. Mirafit’s M3 6ft International and Bulldog’s Shorty both do this.
What you give up is loadable sleeve length: 250mm on the Mirafit and 223mm on the Bulldog, against 400mm or more on a 7ft bar. With 450mm bumper plates, which are thick for their weight, that fills up fast. With thin cast iron or calibrated discs it is much less of a problem.
Cheap short bars to avoid
There is a category of very cheap 5ft and 6ft bars with short centre sections that will not rack in a power rack and have no published steel specification at all. They are not listed here, because no maker will tell you what they are made of.
If a listing gives you no tensile figure and no load rating, that is the specification: unknown.
