Nina
A flexible platform that caters to a wide range of off-road needs. Stelbel Nina can be designed and built to accommodate even the most specific requirements. Certainly Gravel, but not limited to it. Adaptations include options for tires up to 700x58c or perhaps in the opposite direction, to create a fast All-Road bicycle for long-distance travel.
Description
In 2015, we introduced the Nina model. Since then, Nina has been much more than just a model with well-defined features; it has been the platform on which we’ve met a wide range of our customers’ needs. These customers are not only looking for a custom-made Gravel frame using the finest available steel, but they often require an even higher level of personalization.
The Stelbel Nina model has evolved over time, adopting new standards and adapting to the changing demands of the market. In its current standard configuration, it is a frame designed for use on rough terrain, with the capability to accommodate tires up to 700x42c. It is available for outfitting with any type of groupset – mechanical, electronic, or wireless – and offers 1x or 2x transmission options. On it you can mount a specific Gravel, Road, or, in special cases, even a MTB groupset.
Nina is constructed using the finest Columbus steel, primarily from the Life tubing family, featuring double and triple butted tubes. During its construction, the tubing mitering is extremely precise, and the welds follow Stelbel’s specific TIG technique, with a subsequent phase of filing and finishing the joints to enhance the overall aesthetics of the product.
The evolution of Nina over the years has also led to a new graphic design. Today, the Nina model features graphics inspired by the rock engravings found in the Bergamo valleys caves, emphasizing the mountainous and adventurous spirit of this bicycle and our connection to the places where we have always tested our prototypes.
The standard fork provided for this frame is the Columbus Futura Gravel, with a 1”¼ tapered steerer at the bottom, paired with a 44mm head tube that allows for the installation of an external headset. It’s worth noting that we allow for fork upgrades. Columbus and Enve forks that can allow to greater tire clearances. Up to 700x58c.
The routing for the rear brake hose and mechanical gear cables (if present), traditionally run internally through the frame’s Down Tube, while it remains external above the rear Chain Stays. Just note that since this is a fully customizable model, we are always happy to discuss and accommodate individual preferences.
Upon request, you can customize the bicycle with numerous bottle cage mounts, Anything Cages, fenders, or racks of various shapes and sizes.
As with the rest of the Stelbel range, the Nina model is exclusively handcrafted in Italy and made to order.

Geometry
Each and every Stelbel frame is made to measure and designed with a custom geometry. After an order is confirmed and a deposit payment placed, the frame design will start based on the available information and documents (Measurements form, Bike-fit report, …). Customer will be interviewed to better understand riding style, wishes, goals and expectations for the new bike. A frame’s CAD drawing will be shared to be commented, analyzed, refined and eventually approved before manufacturing can 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.
