Gelu S-Series Carbon Saddle
The Gelu S-Series is the longer platform saddle in the Gelu range.
It is built for riders who move around on the saddle, rather than staying locked into one fixed position. The longer shape gives you more usable platform under the body, so you can shift forward, settle back, climb, cruise or change position more naturally during the ride.
The S-Series gives you a very light full carbon saddle with a longer, flatter feel and a clean custom finish option. It is handmade in Portugal and available in two versions: the stronger S1 and the lighter S3.
Why choose the Gelu S-Series?
- ⚡ From approx. 50g
- 📏 Longer saddle platform
- 🧘 Easier position changes
- 🎨 Custom finish available
Built for riders who move around
Some riders like a short, fixed saddle position. Others naturally move forward and back depending on effort, terrain and hand position.
The Gelu S-Series is made for the second rider.
The longer platform gives you more room to adjust your position while riding. That makes it a strong choice for road bikes, performance recreational builds, urban bikes and riders who prefer a more traditional saddle length without giving up serious weight savings.
Full carbon, low weight, clean finish
Like the rest of the Gelu saddle range, the S-Series uses a full carbon construction with carbon rails and a large central pressure relief opening.
The result is a very light saddle that gives your bike a cleaner, sharper and more personal finish.
The S3 starts from approx. 50g in the unvarnished polished carbon version, while the S1 gives you the stronger S-Series option with a higher rider weight limit.

Gelu S-Series FAQs
Who is the Gelu S-Series best for?
The S-Series is best for riders who prefer a longer saddle platform and like being able to move position during the ride. It suits road bikes, performance recreational bikes, urban bikes and, in the S1 version, MTB use.
What is the difference between the S1 and S3?
The S1 is the stronger option with a 115kg rider weight limit and a longer 270mm platform. The S3 is the lighter option at approx. 50g, with an 85kg rider weight limit and a 255mm platform.
Is the S-Series the lightest Gelu saddle?
No. The K-Series is the lightest and most minimal Gelu saddle range. The S-Series is for riders who want a longer platform while still getting a very light full carbon saddle.
Does the S-Series have pressure relief?
Yes. The S-Series has a large central opening designed to reduce pressure through the centre of the saddle.
Can I customise the finish?
Yes. Gelu offers custom finish options including colours, names and logos. This is ideal if you want the saddle to match a specific bike build, team colour or personal design.
How long does delivery usually take?
Gelu saddles are handmade in Portugal. Delivery is usually around 3 weeks, depending on the model and custom finish requirements.
Which Gelu saddle should I choose if I want the lightest option?
Choose the K-Series if weight is the absolute priority. Choose the S-Series if you still want a very light saddle, but prefer a longer platform with more room to change position.
