Are bike suspension seat posts any good?
A suspension seatpost is a great comfort upgrade, as it will both absorb bigger hits, as well as dampen vibrations coming up from the road. This essentially means you’ll feel fresher at the end of a long ride. For anything slow and off-road, you cannot beat a spring-damped seatpost.May 9, 2021
Do seat suspension posts work?
The advantage of a suspension seatpost is that it will help absorb big hits and other impacts from the ground below, allowing you to pedal through bumps while also reducing the fatigue on your body. Suspension seatposts have been measured to be multiple times more effective than any rigid seatpost.May 24, 2019
What does the seat post do on a bike?
It supports the rider at a correct seat height for climbing and general cadence but can drop by a significant margin at the touch of a lever, to place you in a better attack position when descending.Sep 21, 2021
Is it OK to use a seatpost shim?
As far as safe to use – as long as the shim is at least as long as the minimum seat post insertion required for the frame, in theory you are stressing the frame no more than using the correct diameter seat post.Feb 20, 2017
How do I know which seatpost to buy?
To find out the diameter of your seatpost, you must remove the seatpost from the bicycle frame and look for the size, which is stamped just below the “Minimum Insert” line toward the bottom. The number will be a three-digit number (such as 26.8 or 27.2 or 31.6).
Is a suspension seatpost worth it?
A suspension seatpost is a great comfort upgrade, as it will both absorb bigger hits, as well as dampen vibrations coming up from the road. This essentially means you’ll feel fresher at the end of a long ride. For anything slow and off-road, you cannot beat a spring-damped seatpost.May 9, 2021
What are offset seatposts for?
A seatpost with offset is necessary when the seat tube angle of the frame is too steep to give the desired saddle setback (the horizontal distance between a plumb line hung from the nose of the saddle and the bottom bracket spindle). Conversely, an “in line” post may be required if the seat tube angle is too slack.
Do I need a zero offset seatpost?
The zero offset helps to put those folks over the pedal easier. Zero offset posts also work well if the top tube (real or virtual) is longer then ideal. Moving the seat forward reduces the distance between the stem and the saddle.May 9, 2017

Can I put carbon seatpost in an Aluminium frame?
Carbon will galvanically corrode with aluminum if it is not protected. Use CF assembly paste, it will keep the post from slipping at lower torques and protect the carbon/metal interface. Calfee and Zinn agree to grease all carbon posts, but some manufacturers say not to grease.Oct 30, 2007
Do carbon seatposts break?
Registered. carbon seatposts not only break from being run very high, but also from being run low, because the flex is in in a smaller area, i had an easton post do this.It wasn’t a catastrophic failure just a crack.Sep 10, 2010
