    Snapped very very easily - "Steer clear"
  

*by E***W on Reviewed in the United Kingdom on 15 March 2022*

There's an old adage that can get something that's 2 of strong, light and cheap but never all three. This is light and cheap but certainly not strong. It broke after half a dozen uses on wife's bike - she's 50Kg and his was on her road bike used to commute to work.The post was set using a torque wrench to get the right tension and only 4 inches of post were exposed so there is no excuses other than a really poor part.

    Surprise!

For the price i wasn't expecting much, but this is a quality made and really nice looking seat post.

    Dangerous
  

*by A***R on Reviewed in the United Kingdom on 24 January 2022*

I've just taken my bike in for a service, & the shop owner told me to take the post out as they are unsafe, as a number of them have broken. Not happy with this purchase.
