Titanium | 29er | 650B+ | Pinion C1.12 | Gates Carbon Drive


Designed and handcrafted in Holland

With the 2024 pANTher, we have raised the bar again. This is the most advanced hardtail in technical terms. The made in the Netherlands titanium frame is specifically developed around a Pinion gearbox. Oversized tubing maintains the stiffness for a sharp handling bike without sacrificing the natural damping qualities of titanium. Our exclusive square chainstays offer stiffness for a maximum durability of the belt drive. And the original CNC’d axANTer eccentric axle mounting for adjusting the belt gives a maintenance free drive line.

The pANTher is our most versatile bike up to date. Shine on the downhills or go on an off-road adventure trip.



Just like the effort in selecting our high-performance materials and the diligence put into our designs, we equally value the parts that make up a complete bike. We offer our Signature Build, with a selection of parts that we feel offer the performance and reliability that is fitting for the pANTher.  It’s also our relationship with the people behind the various brands, that similarly put their hearts and souls in the products they make.

Each bike is built individually and we will take personal preferences seriously. So consider our Signature Build more as a start into a journey that begins with selecting a pANTher frame.

We find that geometries are very personal. Yet, they are affected by emerging new mountain biking disciplines, new insights in performance, the development of new technologies, and of course parts. As such, proper geometries are not developed overnight and evolve over time. We are not very progressive in our adjustments, and incremental changes are only made based upon serious testing.

At 11ANTS we are fortunate to have a tame accountant who does not look over our shoulder during the design and manufacturing process. With great attention to detail we look for technically optimal design solutions with cost considerations (and our accountant) taking a backseat. The axANTer, our elegant and vastly stiffer alternative to the sliding drop-out is an example of what happens when the engineers are in charge.

11ANTS will not present an entire new line up of candy-colored bikes each year. Our current models will continue to be tweaked and incrementally improved upon. That said, we do have a few ideas for 2 or 3 new models which will see the light in the near future.


Form follows function. We design with ride quality, stiffness and low maintenance in mind. The form of the bike that follows, results from the functional requirements.


We innovate because standard frame parts do not meet our standards. From tubing down to cable guides, all frame parts are designed in-house.


Most members of 11ANTS have been riding mountain and expedition bikes for more than 30 years. Our history and experience feeds the direction in which we develop our bikes.


Evolution is a very powerful process. Our bikes continue to evolve as we keep looking for better solutions and incorporate feedback from riders.


The axANTer is the world’s first and only eccentric axle mounting system with integrated revolving post mount. It ensures perfect aligment at all times.

post frANT

The post frANT is our solution to tightening your precious seat post. The titanium inserts line out during tightening securing your seat post in all conditions.


Our CNC machined yokes have increased stiffness, a lower weight and improve pedaling efficiency. They also allows us to build to closer tolerances.

Square chain stays

Side-way flex on bikes should be avoided, unless you want your bike to ride like a wet noodle. That’s why we use over-sized square chain stays on all our bikes.

axANTer PM-P

Our revolving post mount is a signature design that breaths simplicity, performance and a maintenance friendly solution.

CNC’d drop outs

CNC machined hooded rear drop-outs increases lateral rigidity. Positioning with the axANTer also allows to adjust for geometry preferences.

Butted Head Tube

11ANTS likes straight gauge tubes, just because of their inherit performance properties. Our head tube is the only single butted tube in our frames.

Cable Guidance

Nothing really fancy here! Just a CNC’ed aluminium cable guidance designed in such a way that it has been approved for anyone above 4 years old.
