Description

The Nina is a constantly evolving project. It is a frame created for off-road and mixed terrain that can also adapt to the most unusual requests.

Born to compete in cyclocross races, over time it has evolved to meet new standards and maintaining a transformative nature.

Custom geometry and wide ranging tire clearance makes the Nina an ideal frame for bike packing adventures, divide style competitions, gravel riding, single track and more.

It can be designed as a racing frame with 700 x 30c road slicks or as a rigid MTB with drop handlebars and 650b x 2.1” tires

What remains consistent with the Nina is special double and triple-butted from Columbus Tubi, and as always with Stelbel, TIG welded in our signature style to ensure the highest possible performance.

The model meets the latest standards using flat mount and 12mm thru axles. You can have up to 4 bottle holders, mudguards & rack mounts, anything cages, the list goes on!

Fork selection will influence the main characteristics of the frame and we can offer different alternatives from Columbus Tubi, Enve, 3T and WR Compositi and also our custom bikepacking specific 1 “⅛ steel fork.

The frame can be adapted to a variety of groupset choices – 1X, 2X, internal or external (or eTAP) cabling, mechanical or electronic compatibility. The options are too many to list and we can accommodate any specific requests.

The 44mm head tube accepts an external headset and allows the installation of forks with 1 “⅛, 1” ¼ and 1 “½ steerers.

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

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 info@stelbel.it 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.
