I have just “invested” in one and why didn’t someone tell me about them years ago ?

They are truly awesome – completely changed my riding

Why have you starred out the two letters between n and s ?

It seemed rude for our younger viewers and those of a sensible disposition 😀

Nits innit. Shameful affliction.

People have been telling you about them for years. You chose to ignore

They are brilliant and I’m a recent convert as well, however mine has just been returned to the shop to go back after only a dozen of so rides.
There is vertical movement in the post and its worn the anodizing.
The shop have never seen this problem before, so we’ll see how long it takes to get back to me. I’ve managed to find a cheap seatpost to keep me riding in the meantime.

this is true but they obviously didn’t talk loudly or in simple enough words for me, so it is their fault
