Nitrous Ti Complete Bike

6 items left



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 cross country 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, fully modern Cross Country mountain bike with up to date geometry that utilizes a beautiful steering, short stem and a wide bar. 

Voila'! A bike 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 trail networks.

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 cross country / trail 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 , fully modern XC sled, ‘downcounty’ 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.

Light, Lively & a Blast to Ride. Best Bike Value I've found Anywhere.

My new Turner Nitrous arrived last week and going in I had high hopes and was far from disappointed. The SRAM XO build kit and Rock Shox SID fork is as premium of a spec as the frame. As expected, the Ti frame is feather light and the welds are expertly executed. To finish, the Knight carbon wheels with Hadley hubs are not only light, but look amazing as well.

The proof is in the ride though, isn't it? Well, I'd have to say that this package is the perfect one. The feel of the bike is light and lively but not twitchy. I've ridden moderately technical trails and no matter the terrain it feels like I am one with the bike and it is practically thinking for me. Silky smooth and compliant. Spritely but stable at the same time.

Finally, if one has done any digging at all on value for the dollar, this is the bike not to be beat. Not only are you talking about a bike designed by a guy who can really ride, but the component spec with a Ti frame at less than 6K is almost questionable - I don't know why this isn't at least $1500 north of the list price. The wheel/tire combo would be at least $2K retail.

Get one of these before they figure out what they are really worth - you won't regret it.
