The Nina XCr is born out of the urge to create the perfect Gravel Racer – an off-road bike designed for those who love speed and wish to get away from the tarmac. 

Gravel bikes offer a breadth of abilities from single track MTB trails to fast all-road riding. The Nina XCr targets the riders who want speed, performance, agility paired with a lighter frame and up to 42c tires.

The custom geometry and tire clearance of 42c or 38c with fenders makes the Nina XCr an ideal frame for Gravel races, fast on and off-road bike packing trips or a visit to the legendary white roads of Tuscany. The stainless steel tubes make the frame lighter and stiffer compared to the standard Nina frameset.

The Nina XCr is built with custom XCr stainless steel double butted tubing from Columbus Tubi, and as always with Stelbel, TIG welded in our signature style to ensure the highest possible performance.

The Nina XCr meets the latest standards using flat mount and 12mm thru-axles. You can have up to 3 bottle cages, mudguards, top tube bag mounts or as well as mounts inside the frame triangle for a strap-free frame bag for a super clean look. 

The Columbus Futura Gravel Carbon fork features the latest flat mount standard, thru-axle and a 1 ¼” tapered steerer. The 44mm head tube accepts an external headset.

The frame can be adapted to a variety of groupset choices – 1x, 2x, internal or external (or eTAP) cabling, mechanical or electronic compatibility. The signature setup for a mechanical disc groupset is designed with internal cable routing through the down tube and external on top of the chain stays. Being a fully custom project we are happy to discuss your personal preferences.

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

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.
