Certainly are a lot of dicks posting on this thread – wtf does it matter if someone wants to wear knee pads for riding other than full on DH? Stuff like g-form is so good it doesn’t detract in anyway from riding enjoyment so why not use them if you want a bit of insurance against buggering up your knees and elbows?
The helmet analogy someone made was entirely valid, I’m guessing most people don’t wear helmets these days solely as they could die without one, more like they want to reduce the damage any impact has. Helmets have moved on to such an extent that the same argument holds really, they’re that unobtrusive that even though they’re not a guaranteed life-saver then you may as well wear one anyway (assuming you value saving yourself from injury more than you value what other people think of you).
Still too early to say how well g-form pads last but my 661 evo’s looked pretty ragged after only a few rides and the g-forms came out shiny new after a 40c wash, as long as the stitching holds up I think they’re onto a winner (just size up from their chart IME).
