Gravel Wheelset - The C23G

Gravel bikes are becoming very popular, new models and components for these super fun and versatile bikes are being launched all the time. While they are the favorites of many cycle tourists, they are also in the sights of performance athletes. In lots of countries, there already are exclusive events in the sport, in addition to events with the gravel bike category.

C23G, the carbon gravel wheelset from Session .

Recently we launched the C23G. This wheelset is a full carbon clincher tubeless ready wheel for gravel bikes geared towards high performance. They have 23mm of internal width, providing more traction and grip and creating the perfect combination with wider tires of this segment. If your bike can fit tires wider than 38mm, these are the wheels you need to explore your full potential.


The 30mm depth made this wheel very versatile, with an incredible weight for climbing and super fast when taking off. This pattern is excellent for facing the roads and helping the bike roll. We chose the best components to assemble the C23G wheelset, we use the Session Road Disc hubs with the best spokes in the world, the CX Ray from Sapim. As well as nipples also from the Belgian manufacturer. With this set, we deliver a super fast, reliable and very light wheel, the C23G wheelset weighs approximately 1650 grams.

An extreme tested wheel for over 10,000 kilometers.

Before launching the wheel on the market, we made exhaustive tests on materials and components, always under the most severe conditions. Only in the hands of the gravel specialist, Ulisses Nunes Abbud, more than 10,000 kilometers were ridden in one year. Ulisses is a reference in gravel biking in the United States, where he lives. Session is a Brazilian brand that I have great confidence in (I have been relying on their “stem” and “handlebars” for years), so I did not hesitate to compete 200 miles, on the gravel, without ever testing the wheels before. Commented Ulisses. Our designers created dozens of simulations and with the help of experienced athletes like Ulisses, we achieved, what we believe to be the perfect configuration for a gravel wheel.



The 23mm internal width and the 30mm depth faced the most varied terrain in the tests and, with the right tires, this wheel can help you go further and faster. In more than 10,000km rides under the most diverse circumstances and the most varied types of gravel, I feel comfortable recommending Session C23G wheelset to all those who are looking for a good option for the gravel bike. It is a wheel with excellent build quality, light and rigid. If it were not, it would have at least untrued, but they remain intact.
