Been using FMF 909 grips for the last number of years. Usually getting 3 months out of them before they were trash.
Grips have served me well
Just went back to Oury Waffle grips.
Reason being is I dont like wearing gloves. With the 909 grips they would become slimey on hard rides and even more so down here were it is hot.
Theory is the waffles will let my hands breath better and i will be able to maintain control
