Great back up from One up.
I ordered a 170 post, whilst fitting I managed to bend the actuator .
They very kindly sent out a new actuator for free even though this was my fault .
Whilst fitting I’ve realised the 170 is really too long for my frame and inside leg length.
They have said they’re happy to swap the seatpost over for the 150 version.
Really pleased with their response and thought I’d share my experience .
