Does Saddle Weight Matter?
The saddle is the only component for which the rider is more anxious about the comfort it renders regardless of the weight. The reason being, saddle makes direct contact with the most sensitive part of your body.
Furthermore, I would like to draw your attention to the fact that no matter how many times you have replaced your saddle with the better version each time you ride.
Your expectation can never meet the level of satisfaction and comfort you enjoy while sitting on an armchair.
Note (source): You should never be numb anywhere when riding your bike. If you experience numbness at any time while riding, you should first get a bike fit and then a saddle upgrade.

Which saddle should you buy?
Which saddle should you buy? I would say the saddle choice should solely depend upon the bike you are riding.

The video below will help you choose which one is the best saddle for you and why,
If you are riding a road bike the wider area on the rear side of the road saddle can support your sit bones and therefore benefits in a course that includes climbing, descending, etc.
Whereas TT saddles are designed to ride in a further forward position on the saddle to achieve aerodynamics posture.
The front two-thirds of the TT saddle is meant to support the rider’s weight so that a rider can use aero bars readily. Therefore TT saddles are most suitable for time trial bikes.
What makes a saddle TT specific?
Following features in a saddle makes it most suited for triathlons and time trial rides
- Long nose that supports pressure applied by a rider due to forward lean posture.
- Added padding to make rider sit in forwarding perched position.
- Grip features on the nose that refrain rider from slipping whilst riding in an aero position.
- Some TT saddles have a cut-out style that features a channel at the rear side of the saddle to relieve pressure on the pelvis while using aero bars.

Does the Seat post material make a difference?
Does seat post material matter? Yes, the choice of material matters a lot. It’s interesting to note that the weight range of the road and aero seat posts doesn’t diverge greatly until we talk about the material used to construct them.
The carbon seat posts have been designed to replace aluminum/titanium frames to remove excess weight from the bike. Carbon seat post weight can lie in the range of 120 to 280g. Carbon seat posts make rides smoother and unambiguously comfortable.
“According to the data available, a well-designed carbon Seat post flexes at a rate 100x greater than a steel frame”
It has been found that a carbon seat post needs a lesser amount of force to flex compared to standard bike frames (source).
A flexible seat post helps in reducing road vibrations frequency and helps with big impacts in terrains such as dirt roads.
Carbon Seat post Vs Aluminum Seat post
The following tables can help you compare the weight of different seat posts and how the material affects the weight.

What is the world’s lightest bike Saddle?
Next comes the weight. Are you in search of the world’s lightest bike saddle? It was a challenge to call forth the saddle that should weigh less than 40grams. We already have saddles such as S3 of 45g, G3 of 50g, and E3 of 55g by Gelu Carbon Creation Company.
