I have a very short framed triplet which tapers down from the captain to the rear. My child sits in the middle and my adult stoker on the back. Her seatpost is a 27.2 410mm. Its almost up to the max. I want to be able to ride with taller riders every once in a while (ie. family, other fast riders in my group).
As such I am needing to get a really tall seatpost, probably 500mm.
I know that the comotion telescoping thing would probably work, but I think it might be a larger diameter. Also, I don't really want to shell out $100 for it.
Does anyone know of a source to get what I'm looking for.
Lastly, you might be thinking, why not trade stoker positions, the seattube is taller in the middle and would accomodate a taller rider. This is correct, however, we want to leave the little one in the middle because there are lots of times when it is only the two of us on the triplet. And it would be a real pain switch back and forth all the time.
Thank you very much.
