Made from durable thermoplastic elastomer / rubber, or TPR, the Ridge is a two-tone ergo bike grip with an aluminum inner lock-on ring that is CNC-machined and color-anodized. The fine-tuned elasticity of the TPR coupled with the way it is shaped and textured makes the Ridge an optimized grip in terms of comfort and total non-slip traction for the rider. The wrist support is so formed that its edge is streamlined from outer end to center to fit the thumb of the rider to a T. This curved edge resembles a ridge, which is why it’s named. The Ridge helps get riders anywhere they want to be, high and low, more comfortably.
