What a price! This is the last of the 2022 models, and you are probably wondering what is the difference between 2022 and 2023? Well, the only change that really matters is the rear brake mount, the other tweaks are marginal..  These 2022 models were designed around the 'flat mount' style brakes. For the last 2 years all the Nitrous' have required the flat mount rear caliper, easily sourced online and an inexpensive swap to your  'MTB' brakeset. The calipers take the same size pads as an XC MTB caliper, and put out the same power, in fact more and more Big Company XC bikes are coming from the factories built up with flat mount rear brakes due to their compact size, light weight and fitment on compact rear triangles. 

So why change? Because Turner Bikes is a small brand , and sourcing the MTB brake system from SRAM or Shimano with a flat mount rear caliper has not gotten any easier. This is your chance to grab a fantastic deal on a very fast, super modern XC / trail bike! 

I will be glad to either point you in the direction of a flat mount caliper online or I might even have what you need in stock!  Just contact   

Over the last several years of riding gravel, I have fully enjoyed the speed and the feeling of being really connected to the roads and trails, with nothing more than the air in my tires muting the impacts.  But as I pushed the limits of a gravel bike further and further, I realized there was no tire combination, no geometry, no drop bar shape that would create the control one gets on a mountain bike with flat bar.

That’s why the mountain bike was invented right?!

But for many of us, there is also a ton of riding that does not require a full suspension bike. So I decided to make a fast, lively feeling mountain bike with stable, modern geometry that utilizes a beautiful steering, short stem and install a wide bar. 

Voila, something far more capable feeling than any gravel bike when the going gets rough, and conversely far more nimble and responsive than a full suspension bike for powering along on the less demanding terrain that so many of us have easy access to.

The first part of designing the Nitrous was to make it inspiring to ride up the hill, almost urging you to new speed. With the low weight and balanced geometry, you will look at the steep sections of your favorite trails and know you can go further and faster than ever before.  To create that snappy feel I pulled the chainstays in nice and short. As always there is a balance to frame geometry aspects and the first couple protos were even shorter, but I really felt the bike should be more stable.  So the chainstay was stretched just a bit for some more stability on ungroomed trails. To maintain the awesome traction on the rear wheel, the seat tube angle was slackened a little.   

For me, the 'longer’ part of the longer, lower, slacker ditty means that you can now install a crisp steering, super short stem and still be in a focused, powerful position while climbing. This  ‘longer’ aspect to frame geometry also puts the front wheel further in front of your center of mass for more descending stability, and this is especially important when pushing the limits outside of the smoother flow trail networks.

Then there is 'lower', while not a super low bottom bracket, the Nitrous does have a very short (lower!)  seat tube allowing longer dropper posts. Whether you want the big drop for getting way over the back wheel in the rough or looking bitchen in the parking lot, this new school frame dimension allow the seat to be 'lower' than ever!

Ok, now we need to talk about the ‘slacker’ part of the ditty. To be sure the Nitrous is slacker than most hardtails ever built. But it is by no means the slackest, the race to create the most extreme numbers is over. What is important is that the head angle is properly designed for the type of riding most will do on the Nitrous. Not so slack as to cause wheel flop on the tight technical turns and more importantly, it is not so slack that one cannot weight the front wheel on flatter turns.

The results of all the testing and geometry tweaking was to give the stability we expect out of a modern bike, without losing the liveliness we crave from a high performance hardtail. 

So, is the Nitrous a fast XC bike or is it a stable ‘downcounty’ trail bike capable of zooming thru the woods ducking branches and carving up the spaces between the trees, or is it the perfect bike for Leadville type endurance races? I would say yes, it is.

Subtle shaping at the lower end of the Down Tube to the spread load over the BB shell and a dramatically flared Seat Tube both increase lateral rigidity for better feel when smashing the pedals. Along with the custom tapered chainstays, these subtle features set the Turner Ti ahead of the pack when it comes to ride tuning.

12mm Bolted AXLE

Bolts are stronger, stiffer, and simpler. Which is exactly why all our bikes come with them, it simply makes sense.



Every aspect of this Turner Ti frame is designed and engineered in the USA. From the gorgeous CNC tapered head tubes to the proprietary dropouts, we have designed every aspect of the frame.

As you probably figured out from the great price and long list of standard features, this frame is imported. We found this factory when we were producing the carbon Flux frames years ago. Soon after we started developing the first Ti Cyclosys with them. Our frames are not the first or the only Ti bicycle frames they build, as they are a factory long known for building world-class titanium mountain and road frames. What drew us to this factory was their ability to taper and create butted titanium tubing, and their massive CNC capabilities allowing us to create exactly what we wanted with out cookie cutter head tubes, bottom brackets and dropouts. Even our chainstay bridge is CNC out of billet to be super thin and not create a mud shelf! 

T47 BB

‘T’ stands for threaded! Due to popular demand threads are back, and the new T47 offers bigger bearings & longer service life than older threaded standards. It will easily fit the larger and 30mm aluminum spindle creating a stiffer crank assembly, which is up to 18% lighter than the traditional steel spindle system.


As this is a cross country oriented  bike, it has the latest standard in XC mountain bike brake mounting, Flat Mount 160. Now all disc brake manufacturers offer the flat-mount caliper due to the lighter weight and sleek look of the new caliper.


Why offer a Guarantee?

Simply put, we know that you are going to love your new Turner Bike. But given the chance that it just doesn’t seem to fit right, we want to ensure that you will be happy in the long run.

Our customer service rocks and our bikes ride like no other, but in the end, we want it to fit you.  If you cannot get comfortable on your new Turner Bike within 5 days of receiving it, give us a call and we will work out a solution, you may only need a different stem, or length of seat post. If that won't work, a different size frame can be swapped out.

Love this bike

Was in the market for a hardtail as I find myself riding a good bit of mixed FS road and trail together. I rode Turner Bikes back in the early 2000's and honestly didn't know Dave was putting out new bikes until I started shopping. I reached out and DT and he was fantastic answering my many questions and I settled on an XL Nitrous with the Fox fork. I couldn't be happier. My gravel bike (3T Explore) and MTB (Evil Following) have been collecting dust since building this one up. It's perfect for the North Georgia mountains and works like a Swiss Army knife. My build is not super light but works for me. XT mostly, DT Swiss1700 XM, OneUp Dropper/Bars/Stem. 2.4 Ardents front and rear. Weighs 27.5 lbs with pedals. I still have my 2004 Burner hanging around and this bike will be around at least as long! The best customer service and a beautiful product. Buy one.

N+1=yes please

Back to the family. In the day Proud owner of the ultimate trail bike (5spot) and loved it, until I Drank the carbon koolaid…..
I now have seen the error of my ways. Wanted to return to the simple love of riding with a simple machine with superior materials and engineering. Once I saw it (nitrous) I was in.
I have a Ti Gravel and this was the N+1 I was looking for to complete the stable.
So comfortable and capable from the first ride. Modern Slacker geometry climbs and descends like a dream.
Thank you DT for your groundbreaking contributions to MTB over the years and getting us back to our roots.
Well done Sir!

Bought after one ride on my husbands

This bike is awesome. My favorite part is how great it corners. It is surprisingly good at descending for a hardtail and of course a great climber, but it was the tight turns I can accomplish that really impressed me. Cornering is my greatest area of growth as a cyclist, and this bike just made it easier. My husband and I were out riding and I asked if we could trade bikes for that ride so I could try out his new Turner Nitrous. I was all smiles at the end of the ride and the next thing you know we have a second Turner bike at our house. If you are wondering if you should take the leap and buy this bike, my advice, do it if you like having fun! It's been a long time since I've had a hardtail and I can see myself riding this bike the majority of the time.

Todd from Ventura, CA

Did my research as I wanted to find a modern geo hard tail for 100 mile endurance racing. Built the frame and fork up with carbon wheels, carbon seat post, and carbon handle bars. Climbs great and is super fun and fast on the downhill. I also appreciate the great customer feedback when emailing Turner with my build questions.

Nitrous aka NOS

Fast on climbs and snappy on the turns! No excuses to wait any longer with this promotion as I’ve been eyeing for a Ti hardtail mtb instead of just another carbon. Oh boy, am I glad I clicked the order confirmed button lolz!
