Looking for a cool down or warm up seat post extender for a traditional round tubed seat tube frame?

The seat post extender is made for racers when you need to warm up or cool down after a race, or for when you want a more comfortable sitting position when crusing around, due to the ultra low frame designs and super short race seat posts. You just insert your current seat post and seat into the extender and ride away.
