YY Vertical Twin Cylinders - Wooden Sloper Grip Trainers (Pair)

The YY Vertical Twin Cylinders are a pair of wooden cylinder grips that replicate climbing on slopers and rounded volumes. They're for climbers who want to build open-hand strength, forearm endurance and grip control that a flat edge can't train.

A cylinder gives you nothing to crimp, so the deep forearm muscles do the work. Choose 33mm for demanding, technical precision work or 55mm for power and endurance in a wider pinch-style grip. Hang them vertically for classic gripper work or horizontally for a wider grip that changes how the arms and shoulders engage, using the integrated cord. They're made from recycled rubber wood with a smooth, non-abrasive finish, so long technical sessions don't wreck your skin, and they pair well with a hangboard to vary the load on your muscles.
