What is standard size seat post?
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.
Does a carbon fiber seatpost 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.
Is EC90 seatpost good?
The latest version of Easton’s lightweight EC90 Offset seatpost is impressive, with a one-piece, all-carbon design, a user-friendly clamping system and excellent saddle adjustability. The only shortfall is that the 350mm length is a little short for longer-legged riders.
How do I know my seat post 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.
How do you measure seatpost size?
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 carbon seatpost more comfortable?
As is consistently the case, aluminium is perfectly adequate and will do the job. Carbon seatposts, however, offer greater dampening from road vibrations and are lighter. If you don’t feel your bike needs to be any more comfortable, and you’re not fussed about 100 grams, then aluminium seems like a smart choice.
How are seat post clamps measured?
Note: The seat clamp diameter needs to match the diameter of your seat tube rather than your seatpost, which is a little smaller. For example, a 27.2mm seatpost (a size commonly found on road bikes) fits inside a 28.6mm diameter seat tube, so it’s a 28.6mm clamp you need.
