The symmetrics are the hardest set of training edges in the series. Each of 10 has a left/right-hand partner. The set enables interesting problems to be created and mirrored allowing the climber to identify their weaknesses an thus work on them - a step forward from conventional training system training.
The famous Bleaustone fine surface-texture has also been used to great effect on these holds, resembling the skin preserving properties of wood but with all the predictable friction of resin.
The Trainingstone Symmetrics are currently available in blue.
