Stamina 140 is made for action-packed trails, fast descending, and making light work of the climbs. At home on the loamy countryside of the UK, flowy forest needle tracks of Scandinavia, infinite dusty paths of California, or for those quick 30-second laps on your backyard trails. The geometry allows it to be agile, without compromising on speed, stability, or climbing efficiency.
With 140mm of rear travel, Stamina 140 gives you plenty of freedom over the terrain and is designed for people who want to ride technical trails but not looking to race enduro or do laps of the Bike Park.
Like its longer travel siblings, it’s machined from 7075 T6 aircraft grade aluminum that has superior performance qualities compared to other alloys. Stamina 140 it’s still faster than most, but more agile and playful than its big brother.
With smart features like large tire clearance, space for three water bottles, a silent drivetrain, and easy maintenance by smart design, the Stamina 140 is a true trail ripper without compromise.
Unique Pole Stamina Technology
Stamina is a fully bonded, patent-pending frame structure, that’s unique to the mountain bike industry. We chose a frame material that is used in aerospace technology and innovated a totally new bonding method so that we can make a monocoque frame that is light, stiff, and durable.
Our first CNC bike was the Machine. Stamina bikes evolved from the Machine – a legend that is ridden all over the world. Once we created the Machine, we went back to the drawing board and created three different bikes with a completely new frame construction.
Stamina is for riders who want the best technology in a frame that stands out from the crowd.
Unique Pole Stamina Material
We are the only bicycle manufacturer that produces its frames from aerospace-grade 7075-T6 aluminum. This unique material is much stronger than conventional 6061-T6 aluminum, which is most commonly used in the cycle industry today.
7075-T6 isn’t generally used in the cycling industry due to its inability to weld efficiently. That’s why we CNC machine monocoque frame parts and then bond them together with glue. This method allows us to make much stronger and lighter frames than using traditional welding technics. The way we make Stamina frames is state-of-the-art technology in the mountain biking industry.
We manufacture and assemble all our Stamina frames and bikes in-house in Finland. This ensures the best quality product, a smaller carbon footprint, a shorter supply chain, and guaranteed labor ethics.
Mechanical Testing to the Highest Standards
EFBE TRI-TEST Gravity Cat-5 Certified
Widely recognized as the gold standard in the cycle industry for mechanical testing, the EFBE test is conducted according to internationally recognized and accepted standards – Completely independent, they test bicycles and components to international ISO and European EN standards for many companies.
We are 100% confident in our manufacturing method and materials used on our CNC frames. So much so that we sent a Stamina 180 frame to EFBE in Germany to put it through its paces. Not only did it surpass the recommended standards for frame testing in the industry, but the Stamina frame has been awarded the EFBE TRI-TEST® seal.
The TRI-TEST® is EFBE’s proprietary development, which goes way beyond the established national and international standards and reflects the specific challenges faced by modern bikes. With its three modules – fatigue tests, maximum load tests, and overload tests – in various load cases, it provides a time-lapse simulation of the stresses throughout a bike’s entire life. The Stamina frame underwent eight individual test stages to be awarded the seal of approval.
We are happy that Pole Stamina passed our EFBE TRI-TEST GRAVITY with flying colors – the most comprehensive and realistic test program for DH and Enduro bike frames, going way beyond ISO 4210 requirements with increased test forces and added load cases, which reflect the harsh realities for a modern long-travel Enduro frame – EFBE Prueftechnik GmbH
The proof is in the testing and Stamina passed.
Unique Features of Pole Stamina
Seamless, monocoque frame
We use a completely unique framing method in Stamina bikes, which makes it possible for us to lay the material where it counts.
The finishing gives the frame an exclusive and unique look. The same method is also used in the aerospace industry.
“The Dogbone” swingarm
With our patented swingarm construction, the ride is silent, the bike is stronger and overall easier to maintain. The parts are hollow like bones, and the material has been used where it counts.
Have you ever wished that your frame had more clearance for bigger tires or mud? We have solved the clearance problems that riders in the Northern Hemisphere deal with a lot – there’s so much clearance that you can fit a fist-size rock through this bad boy!
We made the frame and the links so smooth and slick, that mud passes through effortlessly and the bike is super easy to wash after a muddy ride.
Long bearing life by smart design
Our patent-pending frame design has bigger axles and bearings that no one else uses on their bikes – our link axles connecting the rear triangle to the frame are 25mm. This means that we use 25% bigger axles than on a DH fork! The link connection point on the front triangle also uses a 40mm axle.
All bearings used on the frames are Enduro Max bearings and sealed from the trail elements by frame parts. The large frame axle can even be disassembled with a BB tool.
Why should cable routing be an issue?
Cable routing made in the most simple way; outside the frame. With smart frame design, we have been able to make cable routing even cleaner, by using looped cable ties through specially designed holes in the frame, which not only reduces frame material but also weight.
Running cables inside the frame is just a design gimmick – there is no real logical reason why to do it. And SRAM AXS has made internal cable routing obsolete anyway 😉 Simple – silent – fast.
More room for bottles
One bottle? Two bottles, THREE?! You can fit two bottles on the inside of the front triangle and even one on the downtube if you like.
Forget your backpack. Choose where to keep your bottle – close to the head tube for easy access, or down near the BB for better weight distribution.
We listened to our customers and the message was loud and clear: They want their RAW finished bikes to continue to look amazing for longer.
Wet paint and anodizing aren’t an option. We never want to cover the pure awesomeness of the CNC machined surface. So we created an area in our new manufacturing warehouse and invested a good deal into industry-leading equipment that can offer a long-term solution. A unique and innovative surface treatment system.
Going Electric – This is NOT anodizing
After extensive studying and testing, we chose to go with Electrophoretic Clearcoat. Something you haven’t heard about before? That’s not surprising, because its use in the bike industry is unique and as far as we know, has never been done before.
This type of surface treatment is mostly used in industries whose applications have to resist mechanical strain and environmental impacts like salt. It’s also commonly used in the jewelry industry. The coating system has a hard surface and completely clear looks the same as the RAW finish.
As the name suggests, the process involves electricity and exposing the processed part to different solutions. First, the surface is cleared from aluminum oxide and other materials present in the alloy, like zinc, copper, and magnesium. Then an electrical circuit is made between electrodes and parts being processed.
When voltage is introduced to the solution, the clearcoat attaches to the surface of the parts. Finally, the parts are cleaned and placed in a low-temperature oven to remove any moisture and residue left over.
The resulting finish is durable, and impressively only a few microns in thickness. High tolerance parts like bearing races and threads are also completely unaffected by the process.
As with our in-house CNC manufacturing process, we wanted to keep our environmental impact as a high priority and as low as possible. In general, the business of surface coating involves chemicals of the worst type, and we wanted to stay with the most environmentally friendly option possible.
When it comes to green factors, electrophoretic clearcoat ticks all the boxes. As it’s a fully closed system it does not involve any heavy or toxic chemicals and all wastewater is securely stored in tanks and recycled later.
The whole treatment is done in-house, so it also gives us complete control of the processes and by-products.
Raising the Standard
Production at our new on-site clear coat surface treatment facility is now fully operational. All Stamina frames ordered from April 2021 will have the new clear coat Electrophoretic clearcoat applied as a standard procedure.
Along with the standard clearcoat, the new process allows us to create colors too. So far we have successfully applied, tested, and created True Gold and Storm Grey.
True Gold and Storm Grey are available as an additional option and can be included on all stamina frames for a limited time.
If you’re wanting to add even more color combinations to your frame, we can offer True Gold and Storm Grey options to all shock yokes and links on Stamina frames. We’ll also have more colors coming in the future!

On a bike with such progressive geometry, the question of best sizing is one that we get asked a lot. So, we decided to updated our size naming convention. Instead of S, M, L, and XL we’ve replaced it K1, K2, K3, and K4 (the K stands for Koko, which means size in Finnish)
Taking into consideration height crossovers, we have created a size chart matrix that not only covers the rider’s height but incorporates your riding style too. The result is a simple way for you to best choose the bike size to fit their needs – you’re welcome.
For example, if you are 182cm tall and prefer a bike for all-out speed, we would suggest the size K3. If you spend more time at the bike park or prefer a more agile riding style, take the size K2.

“The Stamina 140 is a bike that stands out for both its appearance and how it rides. Talking in trail bike terms, there might not be anything else as capable when the terrain or speed is serious. Interestingly, Pole did this cool trick because it’s still a blast when the ride is tame, only being stifled at near-trackstand speeds where I’d probably fall over regardless.”
“A trail bike should be the perfect all-rounder. A bike you can ride on epic Alpine tours as well as fast after work laps on your home trails, as well as the odd bike park session on flowy trails. The Pole Stamina 140 can take a lot more than you might think and would survive most enduro races with dignity. “
