I'd love to take credit for this, but it was an accident. My LBS ordered me
a Thompson, wasn't sure of the length, got me the longest one.
It was too long.
So they cut 1/8" off and now I have a post that will never, ever slip.
I feel more connected to the bike. Which is good, it feels more efficient.
Who would have thought a seatpost could bob a little? However, I feel the bumps
a little more.
Slipping seatposts has been a problem for me for years. If you remember the Italy pics I threw up, the darn seatpost was low in a couple.
Anyway... if you have problems with the post slipping, getting a real long seatpost might be worth trying.
