I’m new to unicycling (age 49, started in February) and I’ve been riding every day. Lately I’ve been riding at least 20-30 minutes straight with a brisk pace as I’m trying to use the uni for aerobic conditioning, plus I usually spend some time practicing turns, freemounts, trying to idle, etc. Even after lots of adjustments of seat position and height, I’ve been having a lot of crotch pain with the Nimbus gel seat, so I went ahead and bought the KH seat. All I can say is WOW! I went for a 25 minute ride with no pain at all. I definitely give it a 5 star rating!
I could only do about 15 minutes on my Nimbus Gel. The KH FF becomes uncomfortable after a couple of hours. I use a lot of Chamois type cream to help. Some people love the Nimbus Gel though. I gave mine away.
