    Broken handlebar and seatpost replacement

    How long before a handlebar, seatpost, stem, fork should be replaced? Do you replace after certain time or mileage? I snapped the handlebar then 10 days later the seatpost. I got them new when I built the bike two and half years ago and 5500 miles. The handlebar broke at the left side rise bend on a downhill section and caused a crash. I am riding SS and rigid, 29er. I just want to avoid another crash due to equipment.

    Tough to say. I have seatposts that are over 30 years old.
    I broke a 5 year old handlebar, but I had changed brake levers, often with unfriendly to carbon clamps, a gazillion times over that time period, so it owed me nothing.

    That being said if you properly prep and torque your bolts, and use carbon prep on mating surfaces (on carbon bars and seatposts; grease on AL posts), the lifespan should be almost infinite.
