Layback: A seatpost shaft can be inline (i.e. straight, with no kinks or bends) or layback (with a shallow-angled bend towards the top of the shaft which puts the saddles slightly farther back relative to an inline post).
Are all BMX seat posts the same size?
Seat posts come in different lengths ranging from around 135mm to 330mm. BMX seat posts have an outer diameter of 25.4mm which is what most BMX seat posts are today. The old school BMX size is 22.2mm.
What size is a BMX seat post?
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. Tapering seatposts often have a diameter of 22.2 mm (⅞ in) at the top.
Is it worth upgrading to carbon seatpost?
Carbon seatposts are lighter and more expensive, but more importantly, they can be optimized using different layering techniques to achieve an unparalleled ride quality.

Is it OK to clamp carbon seat post?
You can hold the bike by the carbon post if it’s round and you clamp it gently, but you may scratch it unless you’re very careful and the jaws of the repair stand clamp are safe (keep them clean of dirt and wrap a piece of wax paper around the seatpost to help prevent scratches).
Do carbon seatposts reduce vibration?
When choosing between aluminum and carbon seatposts, our tests indicate that the carbon seatpost will offer more vibration damping on high-frequency bumpy surfaces and more flex for big bumps, while also being lighter; but they are more expensive.
How long does a carbon seatpost last?
For example, Canyon recommends that you replace their carbon handlebars and seatposts every 3 years. They also recommend that you replace their carbon forks every 6 years or after a crash.
Do carbon saddles make a difference?
In fact, they have a reputation for being one of the most comfortable saddles available. Carbon has excellent vibration damping capabilities. That makes it the preferred material for many bike parts, including the saddle. Vibration damping results in a much smoother and more comfortable ride.
Do you need carbon paste for carbon seatpost?
Carbon grease/paste is often recommended as a way to reduce tightening torque on handlebars, stems and seatposts while reducing the chance of slipping.
Is it worth upgrading to carbon handlebars?
And while certainly a more expensive way of doing things, there can be little doubt that a set of carbon handlebars will enhance the aesthetics of your bike. Among carbon’s advantages are that it can be moulded into any shape you can think of which allows for fine-tuning of aerodynamics or ergonomics, for example.
Do carbon handlebars break easily?
Yes, carbon can crack and in general, does not like too much force applied in a very small area (yet handlebar is exposed to those situations because you clamp the handlebar to the stem and you clamp leavers to the thin carbon tubes).
How long do carbon bars last?
If you’re a big hucker who never crashes or never moves anything you could easily get five years out of a carbon DH bar. If you’re a skinny, cross-country rider who travels, tweaks his position, changes parts or takes frequent little diggers you might only two years out of your bars.
Should the saddle be higher than the handlebars?
As a general rule of thumb, you want the top of the handlebar about as high (or higher than) the saddle, unless you’re a sporty rider looking to ride fast. Try touching your elbow to the nose of the saddle and reaching forward towards the handlebar with your hand.
What happens if your bike seat is too high?
A saddle that is too high will cause the hips to rock back and forth. Not only does this detract from pedalling efficiency, but it can also be extremely uncomfortable. Discomfort can show up in your lower back or as knee pain (especially in the back of the knee).
What happens if the saddle is too far back horse?
A saddle positioned too far back tends to sit on the “floating ribs”. This is the “bucking reflex point” – pressure on these unsupported ribs causes considerable discomfort, which can lead to bucking as the horse tries to alleviate the pressure.
Is it better to have bike seat higher or lower?
If the levers aren’t suitably arranged, then it’s harder to effectively generate power, and there is risk of injury. If a saddle is too low, then the pedal stroke is over before the muscles have been able to fully do their thing (contract or extend). Increasing saddle height increases power output, up to a point.
Should your leg fully extend on a bike?
Proper position: With your foot at the bottom of the pedal stroke, you should see a slight bend in the leg, reaching about 80-90 percent of full leg extension.
Should my feet touch the ground on a bike?
The height of your saddle is important for the most comfortable position and safe riding style. When you sit on the saddle, both feet should reach the floor and the balls of your feet should be touching the ground.
