[ETC-Discussion] Tamer Seatpost Failure

[Stephen Crawford]

This was a Tamer PivotPlus.  We got it with our Rodriguez tandem in September of 2007 and it has about 2,500 miles on it.  I took the post back to R+E and since they didn't have another Tamer in 25.4mm, Scott gave me a Crane ThudBuster to try.  I hope that Karen likes the ThudBuster because it looks more trouble-free to me:  The base of the head is a machined part of the post - it is not pressed on - and there are fewer moving parts.  I have heard of cases where the elastomer insert ruptured, but I hope that sort of failure would not be catastrophic.  The Tamer design is always under spring tension and depends on a friction fit to keep top on.
