I'm a plus size model, so I needed a stout piece of rubber. The extra firm elastomer fits the bill perfectly. Gives my seat just a bit of cushion while not being sloppy. For the cost of the post versus the cost of the elastomers, it would have been nice if all 5 levels of elastomer were included instead of just 3, but it was easy to order, arrived in 2 days, and was lower in cost than I expected.

I love this product and all thudbuster products it allows me to continue to enjoy bike riding without severe back pain with severe degenerative spine disease and osteoporosis

Very comfortable ride!

Nothing else compares, nothing.
