Brooks claims they are rubber, but if so, it's the hardest rubber I've ever seen. I've already sent it back, and a Terry Liberator is arriving today. I considered both the Terry and the WTB Volt. They are similar in construction, but I opted for the wider seat. Now if only the weather would ease up. I'm a wimp, and just do not enjoy riding in hot, humid conditions. If this keeps up, I'll have to go to starting my rides at 4 AM.These ones are plastic. They never settle in. Tony, I probably have one or two light coloured ones in a box if ever want some more
For what it is worth I have gone from being a welded on Brooks user to a Selle Anatomica user. Cannot see myself going back.
On-road riding. I like riding, on and off-road and the longer (bikepacking/touring) the better. Each to their own of course.
