Bicycle Seatposts

Casual bicycle riders probably do not have to think much of the different parts on their bike. However, when you are more serious about your riding and want to get results, all the bike parts suddenly make a huge difference. After getting the right bicycle wheels, saddle, gears, brakes, and handlebars, put some thought into your seatpost, too, and get the edge you need to be on the winning track.

Seatpost Size

Size does matter, and the correct internal diameter is essential for the seatpost to fit the seat tube. The standad measure is 27.2 mm for most modern MTB and road bikes, while other sizes, such as 25.4 mm and 31.6 mm seatpost sizes are also popular. The latter is of the oversize type and adds stiffness to your ride, while a narrower post feels more comfortable on rougher terrains. In terms of length, longer posts provide more comfort, but it is essential to consider the amount of post that remains inside the tube. If this is too long, you may crack the tube due to a high leverage ratio.

Layback

The type of layback depends on personal preference. If you want to sit farther back, choose a layback seatpost that has a shallow-angled bend at the top of the shaft. Inline bicycle seatposts are straight, with no bends, and you sit more in the front.

Clamp Type

Generally, the clamps accommodate twin-rail saddles, with single-rail options being less popular. The latter also require special types of saddles. If your saddle comes with oversized rails, bigger than the standard 7 mm, double-check that the seatpost clamp is compatible with your saddle.

Material

Both aluminium and carbon constitute great materials for the seatpost, but they differ slightly in weight. Carbon fibre, a common choice for premium bikes, weighs less, but is also more expensive. Aluminium posts stand out for their strength and confidence, making them the first choice for MTB riders.
