Change the silicone to adjust the lever tension.
Higher hardness rating (0-100 scale) gives more tension, lower rating for less tension. Find the most comfortable tension for your hand and the best for your lever setup.
Generic (A design) have equal tension all around, this is the standards for many decades.
Dual Tension (X design) are our innovation to create different tension between cardinal and diagonal. By reducing material on diagonals it creates less tension. Overall the X design have lower tension compare to A design.
We QC every silicone one by one and hardness rating measured using KORI calibrated Durometer, all readings +-2 shore A.
We ship world wide using DHL, shipping cost will be calculated during checkout.
