Jello description sounds like no pain on a long ride! When I checked the Airhawk out on the internet. I was surprised how much they cost and how heavy they are. Is there any problem getting them in place and having them stay there?
No problem...they have a sticky rubber type bottom, so won't slide around easily if you just watch yourself and don't kick it getting on. The regular Airhawk (not the Airhawk II which is cheaper, but made out of a different bladder material) is made of good stuff, like a heavy neoprene rubber. The newer R cushion is the best shape/design for our bikes, IMO. Fits nicely and is not noticeable when sitting on it. When I get off the bike to go in somewhere, I just throw it in the TP. Has a nice metal valve that allows for easy adjustment for the right amount of air, then tucks into the cover and disappears. The trick is to blow it up, then sit on it and let air out until you are almost touching the regular seat, making it feel "squishy" under your butt when you move from cheek to cheek. And the tailbone cutout on the R is a nice feature...if you're a man, the shape of the front allows some room for the "boys" too. I got it for the BSR, but I've used it a couple of times when riding solo and it feels nice. But so far, I don't have any problems with the stock seat, at least for the driver's portion. I don't ride bitch...
