I must admit I was being a little mischievous when I posted this.
Whenever a "new" idea pops up, such as a new saddle, or a continuously variable transmission, a whacky lighting system with "safety" features, an expanding chainwheel, a spokeless wheel, it's always greeted with angry cries that it's been done before, it can't
possibly work, stop wasting our time (which, strictly, should be stop inviting us to waste our own time). This is a pretty easy thing to do because most of the time these things
are daft ideas. It doesn't actually require any thinking: Q: New product idea? A: It's stupid. The end. I don't know why people bother getting so worked up.
When I saw the infinity saddle back at the time of the OP I was of broadly the same opinion as most - it looks like a daft idea, it will probably fail. So I was interested when KT said she was going to get one, and I had the opportunity to discuss it with her. Her opinion was that she'd tried everything else, had been suffering from pressure sores for several months, so anything was worth a go.
So I was interested to see whether people would review their initial "first glance" dismissal in the face of a bit of empirical evidence: a product that has been used successfully (admittedly only by one specific individual) for quite a significant amount of riding (4,000 km in just shy of a month). I wasn't hopeful. And I was right not to be.
As you were.
(Have I told you about my new gearing system ...)
