    Pista Seatpost Measurements

    I recently bent my seatpost on my Bianchi. Like a complete idiot I forgot to remove the seat/seatpost from my bike when going through a particularly low parking garage with the bike on the roof. The frame and fork are fine but the saddle and seatpost are trashed. I found a deal on a used 27.2 X 410 MM Thompson. Will it fit???

    Thanks in advance

    Hard to believe the seat tube top wasn't affected by a blow strong enough to damage your seatpost.

    I was very surprised to see the only damage was to the seatpost and saddle. I was really worried about the headset and fork but everything seems to be fine. I was only going about 3-4mph when it happened, the roof rack took most of the force and was bent to hell. I figured it was a 27.2dia but I thought it couldn't hurt to ask. Thanks guys
