They have a great feel, you pull a little hard and they stop a little quicker, you can really feel the stopping progression with your lever hand. The feed back you get from these pads creates confidence that you have complete braking control even in wet weather. The HS is a front only although they fit a lot of rear brake calipers the HS is to grabby for the rear brake. For street bike rear pads the LS or HF are better options.
