How do I know if a bike seat will fit my bike?
The easiest way to make sure a new seat will fit your existing seat post is to check that it also has two rails beneath the seat (if you are purchasing a brand new bicycle seat, it will do!). This seat post clamp design has become the most popular thanks to its reliability, strength and adjustability.
Are bike seat posts universal?
While there are any number of post diameters out there, most modern road and MTB bike frames accept a seatpost of either 27.2mm in diameter (‘standard’), 30.9 or 31.6mm (‘oversize’). … You can use a shim to enable a 27.2mm seatpost fit into a frame taking a larger standard, but not vice-versa for obvious reasons.
Can you swap bike seats?
This’ll be a pretty speedy, simple, swap. All you’ll need is your new saddle and an allen wrench! It typically takes a 6mm, but that can vary a bit. Either check your seatpost ahead of time, or just have a 4/5/6 or 3-10 handy and you’ll be ready no matter what’s hiding under there.
How do I choose a bike seat post?
Length. Make sure you have the correct length of seatpost for your needs. Seatposts are available in several lengths from 280mm to 400mm so measure the amount of post you have showing (plus the minimum amount of insertion that needs to be in the seat tube) before purchase. If in doubt, measure your old post.
