Setback Vs Straight Seatpost: Which One Is Better?

Finding the right offset for your Seatpost is very crucial. After all, who’d want sore muscles all over even after they’ve been accustomed to riding? 

That’s where setbacks and straight Seatpost come in. Both offer a fundamentally different position to the rider.

So, you may wonder which one is more suitable between setback vs straight seatpost?

Setback Seatpost offers multiple offsets to ensure the comforts of the rider. By measuring the setback Seatpost the offset is determined through the rider’s compatibility. The straight Seatpost on the other hand is the zero offset. It positions the rider more in a forward position.

Sounds complicated? A little more explanation might be of help. So let’s begin!

Detailed Comparison: Setback Vs Straight Seatpost

You’ve seen the basic differences. Now we’ll be talking about more detailed stuff on both Seatpost. 

Hopefully, by the end of this discussion, you’ll find the answers you were looking for.

Sitting Position

When it comes to setbacks it’s mostly about the seating position of the rider. It barely has anything to do with the riding quality. 

Setback Seatpost is for the riders to have a comfortable sitting position on their bicycle. Seatposts vary depending on the offset angle.

So, if you’re wondering what the Seatpost offset is, it is the seating angles. These angles range from 0 to 35 degrees. The setback is to put your position more backward for your comfort. 

The ideal seat back angle is 25 degrees. On the other hand, a straight Seatpost means zero angles. It is also called zero setback Seatpost

The setback measurement is decided based on the rider and his/her bicycle. It’s decided by measuring the bending of knees between the ankle and hip bone.

Depending on the rider’s physic the setback is fitted and it’s changeable. The UPANBIKE Bike Seat Post has an adjustable clamp that you can set according to your comfort. This can be considered as a benefit of setback Seatpost

The straight Seatpost only moves in an up and down position. The setback Seatpost in comparison moves in a tilted way as the Seatpost is fitted.

Although the sitting comfort depends on the rider, setback Seatpost is comfortable for most. At least, you can change the sitting angles.

Saddle Position

Setback Seatpost is suitable for any casual ride. Straight Seatpost can be considered the same but it’s more suitable for bicycle racing. 

For mountain riding, a straight Seatpost is more common. PNW Components Cascade Dropper Post comes with not only mountain riding but several travel options. But setback Seatpost mountain bikes are also used when necessary.

What setback does is that it sets the saddle’s position more backward. The bigger the angle is the further your sitting position will be from the handlebars.

There are long setback Seatpost to make the gap between handlebar and saddle longer. There are also short setbacks to reduce the gap in between. 

Fitting one of the best seller Italian saddles with setbacks might give the best experience.

On the contrary, a straight Seatpost gives the rider a relatively forward seat. Since its position is more perpendicular than angular the saddle’s position is moved forward.

Now, which you would prefer between both totally depends on you.

Rider’s Physic

As we’ve mentioned before, the position of the Seatpost mainly depends on the rider’s physic. Whether you’re comfortable with a setback or straight Seatpost, you’d have to see for yourself.

So if you’re asking why use a setback Seatpost the answer is it’s more convenient.

First, you’d have to be fitted on your bicycle. See what’s the best sitting position for yourself. A wrong sitting position can cause bruising from the seat

The offset you’d require can’t be determined without doing the proper measurement. However, for tall people, we’ve seen that Seatpost is more suitable.

That is because the rider needs more space between the saddle and the handle break. If the space is narrow, it would be uncomfortable for the person to ride.

Similarly, a straight bike Seatpost is more suitable for short people. Since it has a narrow gap the rider can easily reach for the handlebar. The same gap might be narrower for tall people.

If you’ve short femur bones you’re probably more suitable to ride zero setback bikes. It’ll help you to settle on the paddle better. 

Straight Seatpost also works well if the bicycle’s top tube is longer than usual. It removes the gap between the saddle and the stem. But picking the perfectly measured top tube will be a safe option. 

But getting a suitable product can be a hassle. Here we have listed some good quality top tubes that might help you in this regard-

Lastly, about the seat posts, always prefer your comfort first over other criteria. But make sure the bike is nicely set. As a whole, it all depends on the physic and understanding of bike geometry.
