Ergon grips a big improvement over Trek IsoZone grips ?
Are the Ergon basic GS1 grips much better than the Trek IsoZone grips? I currently have the IsoZone grips on a standard handlebar so I dont have the inner rubber padding on the bar, I just have the grip itself. and Ive already got bar ends so I wouldnt need the Ergons with the built in bar ends.
