Frequently Asked Questions (FAQs)
1. Are all bicycle seat posts the same?
The dimensions of the seat tube can vary from bicycle to bicycle, so when choosing a seatpost, it's important to get the correct diameter. The most common diameter is probably 27.2mm, but other sizes between 21.15 and 35mm are often found, as well. Seatposts also vary in length.
2. Do carbon seat posts make a difference?
A good seatpost is the key to achieving a comfortable ride. That's because along with your tyres, seatposts actually make up the bulk of your bike's comfort – in fact, according to the data available, a well-designed carbon seatpost flexes at a rate 100x greater than a steel frame.
3. How do I choose a bike seat post?
What seat post should you buy? Leisure riders just need to make sure they're buying a seat post with the correct diameter and in the correct length. If you're in doubt, remove your existing seat post and have a look towards the end of the post and chances are it will have the diameter and length stamped on it.
4. Are bike seat posts a standard size?
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').
