Snug fit but used some WD 40 and chain lube to get it into place.The seat adjuster is a little tricky to get right but once you do its going nowhere.Great price and looks the part also!

    Just the job
  

*by M***E on Reviewed in the United Kingdom 🇬🇧 on 1 February 2021*

My pretty old mountain bike seat post suffered a fracture to the main bolt holding the saddle in place and I lost bits in the resultant confusion.This is a good replacement. Make sure you get the right diameter (mine was stamped into the seat post).
