My thought on this is that possibly Trek is sending the wrong seatpost size out originally. This website from an LBS shows the bike and you can see how high the seat is compared to the bar. Granted this is a bike where many would want a very aggressive position with a low bar. I don’t need that. I don’t know if you were yo start with the shorter 135 post, can you raise it to get the more aggressive position. Or would you need to order the 175. Which begs the question am I getting the wrong bike ?. Which is a possible yes. And yes it’s a great deal which colors the decision making process. Much to ponder
