|I recently purchased a 250mm Record Carbon seatpost ot use on my Bianchi XL EV2. I have not inserted into the seat tube to date, yet when measuring my current ride (traditional geometry) against my sloping frame, the seat post sits right on the minimum insertion line.
Should I swap for the 350mm seat post, or is it ok for the post to be clamped right on this point? The retailer said he will exchange so long as it has not been used.
I guess in the back of my mind there will always be this concern of it "just" sitting in the seat tube, even though there is 50mm below it. Am I being silly?

|As long as the line is right at the end of the seat tube or just hidden by the seat tube, your OK. If the line is slightly above, I wouldn't do it. Instead of going to a 350 I would go to an Alien carbon or ti post. They are 270mm long and much lighter. They are a pain to set up and the little bolts have a tendency to strip out. If you do go that route, I have a box of replacement bolts and would be more than glad to send you set for the cost of the postage, which would be less than $1. Lastly, I don't trust the Campy carbon post, my friend just broke his and it was put in by the Campy directions and torqued with a torque wrench.|

|How are you measuring? Differing geometrys could effect the outcome.
You should measure from pedal spindal to top of seat on your current ride. Then measure from spindal to top of seat on new ride with the new post. If youre still at the insertion line, you're ok (thats what the line is for, after all).
If youre not confident in your geometrical skills, just slide the post into the new frame and measure with a length of string...but be sure to be very careful not to scratch or crush the post in case it is indeed too short.

|Thanks for the suggestions.
I actually measured the bikes side by side, and rather than inserting the post into the new frame, placed it next to the seat post. The post sits right on the minimum insertion line. The seat is ste on the new post.
I also calculated the distance on paper, and confirmed this :o(
