We’ve been using FSA's Carbon Pro CSI single-bolt seatpost for ages, so it’s about time that it got some credit.
Firstly, because it’s the only single-bolt seat clamp post we’ve never had a problem with and, secondly, because the carbon-wrapped alloy construction works.
At 253g it’s reasonably light, and it doesn’t cost a bomb, although it looks as though it really should.
