    MTB right of passage.......

    There are certain things that are just part of our sport. Breaking parts is one of them. It just comes with the territory. For those that have been in this game for awhile know that parts have evolved tremendously. Strength and durability have become quite amazing. That said, certain parts and manufactures created a lore. Things were tagged as "unbreakable" or "bomb proof".

    All parts fail from time to time. But for certain parts, legend status is given to the rider and the tales of how they actually broke them.

    The Thompson seat post falls into this category. I still remember the day Lidarman bent his in Sedona with his chest. *that* was a special feat to remember.

    Well, I finally broke a Thompson...but I have not tale of glory. Just memories of countless rides with this part.

    Thanks Thompson, you served me well.

    Interesting. Only the 2nd I've seen break like this. Maybe I'll check mine when I get home, just for sh**s and giggles.

    My bent Thomson....

    It bent while attached to my bike (which was attached to my roof) and it hit a parking garage.

    I cut it off and it became a road bike seat post. Still going strong.

    The only other one I have seen "break" was a buddy of mine who came unclipped on a nasty drop and when he hit the G out there was a horrendous cracking sound. He had to ride 8 miles out with no seat. I couldn't stop laughing the whole way back. I know, that's not cool, but I'm OK with it....I drove that day.

    Interesting place for that seatpost to crack! almost looks like the little saddle piece that sits in that 1/2 moon was oversized causing that area to be in tension. Otherwise the stress in that area would be compressive stress and lead to crack propagation...
    Did you by chance use a different saddle piece other than the thomson one?

    I used a Thompson seat post when hauling a trail-a-bike. Never had an issue and the post is still in use. One tough seatpost! And knowing how you ride and how much, I'm sure there are lots of "tales of glory."

    I had a Thomson seatpost crack in the same spot after 6+ years of use.The seatpost was used on at least 5 bikes and hosted many different types of saddles.I did call Thomson about replacement options and they warrantied it without hesitation,,,,,,,,I was only hoping for a deal on a new post. Great products,great C/S

    This is why all our bikes have Thomson seat posts, and soon to have Thomson stems all the way around too. Bomb proof.

    Good post.

    I would have to add Avid Single Digit 7 V-brakes to the list of indestructible bargain parts.
