SPIRGRIPS are patented ergonomic bike grips developed after physiological studies and scientifically validated by scanner. They offer an innovate alternative position on the handlebar that could not be safely reached until now. SPIRGRIPS naturally align the joints of cyclists’ forearms, significantly improve comfort, and reduce or even eliminate joint and muscle pain due to a wrong position. They also allow for increased control and safety while riding and easy access to shift and brake levers. The design of SPIRGRIPS is also sought after from an aesthetic point of view: the quality of the finishes and the clean lines of the profile allow visual continuity with the overall aesthetics of the bicycle. It is easy to install SPIRGRIPS as there is no need to remove or replace original handlebar grips and they are designed for all straight and circular handlebars of 22.2mm or 31.8mm of diameter. They are made of extremely robust material and stainless screws. The handles are also delivered with SPIRGRIPS paste to allow for a perfect mounting on your handlebar (Tightening torque: max. 3 Nm when using the assembly paste included in packaging).
