The Antenore is a tribute to Antenore Belletti, Stelio’s father, as well as the rich history. Stelbel has built stainless steel frames, and was chosen to pay tribute to the best teacher that Stelio could have hoped for. He was among the first to experiment with TIG welding those special steel alloys.

The Antenore was first introduced in 2015 is the most exclusive steel frame in the Stelbel range. It is the modern evolution of the stainless steel frames Stelbel developed in the early 80s, much earlier than the rest of the framebuilding industry. Innovation is a key attitude of Stellbel and we constantly develop and optimize our frames and tubes together with Columbus.

The 3rd generation of the Stelbel Antenore features:

– Overall re-design of the XCr tubing to optimise performance

– Completely new seat tube for 27.2 mm seat posts for increased comfort

– New lighter and stiffer chain stays

– T47 Bottom Bracket Shell

– Re-designed and lighter Head-Tube

– Columbus Futura SLX fork (1”¼)

– New A3 paint scheme

Made with Columbus XCr stainless steel alloy tubing with custom details designed exclusively for this model; the non-conical oval section chainstays are a distinctive feature of modern Stelbel frames, and the Antenore is no exception. Our custom designed chainstays have a 30x20mm oval cross section and compliment our rear dropouts, also made out of stainless steel and CNC machined from a single block.

The cable routing for mechanical shifting is partially internal whereas electronic shifting cables are always routed internally. The shifter cable tension can be adjusted thanks to the stainless steel down tube cable guides equipped with inline adjusters. The bottom bracket shell is equipped with stainless steel external cable guides, and the right chainstay is outfitted with internal rear derailleur cable routing, a typical feature of modern Stelbel road frames. The top tube is equipped with an internal cable guide for the rear brake cable. Internal cable routing for mechanical shifter cables are available on request.

With the 3rd generation of the Antenore, we introduced a new paint scheme leaving the Bottom Bracket area and the rear triangle ‘raw’. Painting the area of the seat clamp allows for a nice merge of a painted carbon seatpost into the silhouette of the frame. The frame features the “Stelbel” name engraved on the head tube, bottom bracket shell and brake bridge.

The geometry is completely custom and the frame can be adapted for mechanical, electronic or wireless groupsets. The Antenore is also available as a disc brake version.

As with all our models, it is a completely custom handmade product made exclusively in Italy.

Granfondo Magazine Antenore Review

Granfondo Magazine voted the Antenore “best in test” out of a group of 12 contenders.

”As soon as we hit the tarmac, we confirmed that this Stelbel is just as fast as it is stunning, all fears of excessive comfort from the steel were quickly wiped away.”

There is also another review from Granfondo Magazine here.

As with all our models, the Antenore is available as a disc version and you can find all the information here.

EPS/Di2Upon Request

The Antenore – as with each and every Stelbel frame – is an artisanal product, according to the requests of each customer, meaning a fully custom geometry.

After an order is confirmed and a deposit payment placed, the frame design will start based on the available information. It is possible to send us a bike fit report or alternatively follow our instructions to complete our measurement form.

Customers will be interviewed to better understand the riding style, personal preferences, goals and expectations for their new bike. We will then share the first CAD drawing of the frame and discuss the details for refinements. After the geometry is approved the manufacturing stage will start.

How to order

You can place an order directly with us via [email protected] or from one of our official retailer partners. An order is confirmed once a deposit payment is received via wire transfer or Paypal. Shortly after, a document providing an overview of the project details and a cad drawing of the frame will be shared for your approval. Pictures of the finished frame/bike will be shared with you prior to requesting the final balance payment. In case you’re considering coming to visit us in Bergamo to discuss the details of a project face to face, or to pick up your new frame/bike, you will be made very welcome by our team.
