This specific one is thinner than my used, shred Joe Rocket ones.
So if you are looking for something to last long and you kinda like smoking your pads (which isnt my case) you should go for another product.
The Alpinestars Sport Knee Sliders are the thinnest and most inexpensive pucks offered by Alpinestars. They are the softest of all models Alpinestars offers. They have great feel but do not last as long as their other models do. This model is best suited for riders who do not drag their knee in every corner.
