Advantages with longer seatpost in the seat tube?5 min read
Asked by: Melissa Sanchez
Does length of seatpost matter?
Seatpost length is a further consideration. While a longer post is generally regarded as offering more comfort, the amount of post ‘sticking out’ of the frame will largely be dependent on your frame size/geometry and your own dimensions (inside leg length etc).
Does seat tube length matter?
Seat tube length doesn’t matter at all for fit. It matters a bit for weight and ride quality, but the geometry of fit depends on the relative position of the bottom bracket, saddle, and the top of the head tube (or the brake hoods, to measure a different way).
Can I put a longer seat post on my bike?
You can adjust the seat post by making it higher (may require a longer seat post than you currently have). Also, some seat posts are straight, whereas others have a setback. The later will move the seat slightly further back on the bicycle.
Does seat post 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.
How long should your seatpost be?
a) Seatpost should end at least 25 millimeters below the lower part of the horizontal tube weld to the seat tube. b) Total inserted length should be at least 90 mm from the top end of the seat tube.
How do I choose seatpost length?
Length. Make sure you have the correct length of seatpost for your needs. Seatposts are available in several lengths from 280mm to 400mm so measure the amount of post you have showing (plus the minimum amount of insertion that needs to be in the seat tube) before purchase. If in doubt, measure your old post.
Will a 30.9 seatpost fit a 31.6 frame?
You can fit a narrower post into a wider frame using a shim (a thin sleeve of aluminium or plastic), for example a 30.9 mm dropper post into a 31.6 mm frame. However, there is no way to fit a wider post in a narrower frame, for example a 31.6 mm post into a 30.9 mm frame.
Can I fit a 200mm dropper post?
Quote from video: To find out the portion of seat post that's outside the frame. And then add that to the frames Center. Bottom bracket to top of seat post length. That will determine the frames. Lowest.
What is the longest seatpost?
Rigid seatposts are the most common type of seatpost with no suspension or dropping capability. The seatpost diameter must match to the seat tube diamater of your frame.
Should bike seat be higher than 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.
Why do my thighs hurt when cycling?
A common reason for encountering cycling leg pain is because of a build-up of lactic acid. Whilst you are cycling the body utilises oxygen to break down glucose for energy. If the exercise intensity is too much you might run out of oxygen for this process.
How do I know if my bike seat is too high?
Determining saddle height with the heel method
Hop on the bike and place your heel on the pedal, in whatever shoes you plan on riding in. Pedal forwards or backwards, but do it slowly. If the saddle is too high, you’ll not be able to pedal smoothly without having to rock your hips from side-to-side, overreaching.
Can I shorten my bike seat post?
Cutting your seat post is one of the most effective ways of tearing your seat tube to pieces. Also, if you cut off the bottom, you will have to adjust the max height line by the same amount…that is, you need a certain amount of length in the tube to have the seat post be safe.
Can I get a shorter seat post?
A seat post can be shortened as long as the new size respects the minimum insertion length of the seat post. If you cut the seat post too much, you risk damaging the seat tube.
Are all bike seat posts 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.
How do you know what size dropper post to get?
To choose the correct travel dropper post, measure from the seatpost collar to the seat rail (in your climbing, or highest setting) on your current bike. Subtract 50mm from this measurement and the resulting number is the maximum travel length dropper post you can comfortably run.
Is a dropper post worth it?
Everyone loves dropper seat posts on their mountain bikes, but no one loves when they are not working properly. Dropper seat posts are crucial for allowing you to get low to build traction when riding rough downhill terrain, corners, and jumps.
Can I put a internal dropper post on any bike?
The choice will depend on whether your bike is compatible with internal or external cable routing. While you can’t set up an internal routing dropper post on a bike frame that does not feature internal cable routing, you can, however, choose to set up external routing if the bike uses either of the options.
