Question: Are bike seat posts universal?

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’). … You can use a shim to enable a 27.2mm seatpost fit into a frame taking a larger standard, but not vice-versa for obvious reasons.

Can you put any bike seat on any bike?

Pretty much most modern seats are interchangeable and will fit most bikes. There are exceptions like dirt jump bikes, racing bikes, BMX bikes, or super expensive bikes.

How do you measure a bike seat post?

You can easily measure the size of the post using a digital caliper and the metric calipers to check the diameter of the existing seat post. First, if you have an old saddle-post that attaches firmly, then you can measure its outer diameter for an accurate estimate of what you need to buy.

Can I cut 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.

Are Gel bike seats any good?

Gel saddles are quite comfortable when new. Unfortunately, the gel tends to get displaced over time, so the comfy-ness tends to not last. However, as geoffc pointed out, these saddles are good introductory saddles for new riders.

Is a wide bike seat more comfortable?

A further misconception is that a wide seat is more comfortable than a narrow one. This really depends on the type of riding you’ll be doing. Certainly, sleek racing saddles don’t look comfortable but wider seats create more friction and chafing when you’re doing lots of pedalling (say on the road, or in a race).

Bike saddles come in different sizes to accommodate different body types. Finding a bike saddle that is the right size for your body mostly has to do with the width of the saddle and how well it supports your ischial tuberosities (sit bones).

Are all 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.

What seat clamp size do I need?

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.

How do I know if my bike seat is too low?

If you go too high, you’ll notice you rock on the saddle or feel a strain at the back of the knee. Pedalling will cease to be smooth and circular, and you may feel your snatching at the bottom of the stroke. If you go too low, you’ll feel compression at the front of the knee.”

Can a seatpost be too long?

It’s too big for you. Yes, you can cut the seatpost. On most seatposts, there is a minimum insertion line machined in to them. You’ll want to scribe your own minimum insertion line based on the amount of seat tube you cut off.
