How do I find out my seatpost size?
To determine it, measure the internal diameter of the seat tube, that is, the one which the seat post inserts into. Make sure you do not confuse it with the tube’s external diameter, it is not needed. Use a precision caliper for that, your measurements must be accurate to 0.1 mm.
Are bike seatposts universal?
Yes, most modern bike seats are universal and can be interchanged with different seat posts. The exceptions are if you have much older equipment or a specialized bike. It’s best to check the number of rails and the rail width on your saddle to ensure a correct fit to the seat adapter.
Can I get a longer seat post on my bike?
Though some brands like to play exception to the rule, the majority of bikes are designed to fit a seatpost of either 31.6mm or 27.2mm. However, whilst you can always cut a seatpost that’s too long, you can’t add to the length if it’s too short.
Why are there so many seatpost sizes?
High-performance bicycles are made of thinner-walled tubing, so the hole will be larger if the outside diameter is kept the same. As a result, a larger seatpost size is often a sign of a higher-quality bicycle. This has resulted in a de facto standard of 27.2mm for high-quality bicycles that have 1 1/8″ O.D.
Are seatposts 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’). Seatpost length is a further consideration.
Are all seatpost the same size?
Seatpost diameters generally range from 22 mm to 35 mm in 0.2 mm increments. The most common size is 27.2 mm (1.07 in) for most bikes, especially for the higher-quality models. BMX bikes commonly use 25.4 seatposts. In some modern bikes with thicker alloy or carbon tubing, larger diameters such as 30.9 mm are used.
Are suspension seatposts any good?
Suspension seatposts can prolong comfort in the saddle, smooth out rough and bumpy terrain, and even help prevent back injuries. There have been various contraptions to suspend and cushion bike saddles since the dawn of cycling. However, many of them had a reputation for being, well, contraptions.
Do carbon seatposts make a difference?
By having a set spring rate, a heavier rider will enjoy a more comfortable ride, while a lighter rider will feel more vibration and big hits. Carbon seatposts also perform much better with more exposed seatpost (2x more flex), which hands the better performance to taller riders.
