Nitrous
The big change for the latest version of the Nitrous is uhh, not much! But even as great as everyone says the Nitrous is, we could not leave it completely unchanged, so, we added a 3D printed chain stay 1/2 yoke, with massive 2.6" tire clearance and room for a 38t round chainring. We also created custom 3D printed cable routing ports that are sleeker and smoother and designed to make it easier to run the internal control lines. There was no change to geometry or tube spec, we would not want to mess with perfection!
The Nitrous already had UDH compatibility, which allows you to use the newest SRAM 'Transmission' rear derailleur and drivetrain. And the Universal Derailleur Hanger fits any derailleur from the last upteen years to be bolted on and with the multiport cable routing options you can choose electric or mechanical shifting and internally routed dropper post.
Why was the Nitrous created? For fast cross country type rides, but with a fully modern geometry. There is no reason that a XC / light trail bike designed to really be pedaled in anger should have angles from 20 years ago. Modern longer, lower, slacker works better than the old geometry on light fast bikes too.
Why a hard tail?? For many of us, there is a ton of riding that does not require a full suspension bike, and with trail sanitation happening daily, more and more trails are becoming more fun on a hardtail!
So, the Nitrous is far more capable feeling than any gravel bike when the going gets rough, and conversely far lighter, and more responsive to pedal than a full suspension bike for powering along on the less demanding terrain that so many of us have access to.

Features
CUSTOM SHAPED TITANIUM TUBESET
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.
DESIGNED IN THE USA
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.

Customer Reviews
So happy with my nitrous. David was a great help in the process and surely made the build much smoother. Out here in the Mojave desert I’m running 120 mm Sid with 2.4 syerra’s and a vittoria airliner xc light insert in the rear. I can run lower psi and man it really screams. Little slacker HT angle helps with the chunk. Climbs like a goat and handles so intuitively. Love it. Thanks David.
I built my 2024 Nitrous with David's generous guidance as a fast and light XC rig. The frame is gorgeous and the ride is smooth and fast. The Nirous is an exceptional climbing machine that is thoroughly capable in all terrain in northern NM I have ridden in the last 6 months. The motto may be N+1, but when N=1 this bike makes me really happy I bought it, as it does everything so well. David is a gem of a human being and his bikes are beautiful, tough, and well executed.
The bike rides like a dream. Geometry is spot on and UDH and T47 BB keep it up to date.
I’ve had my Nitrous for a few months, and plenty of solid rides. This bike is really a sweet spot of light, stiff, compliant and perhaps most importantly, competent. More specifically, this bike is not the superlative of any of the aforementioned qualities, but a master blend of them. The result is a wonderful bike up for an engaging experience on XC and flat to hilly trails especially where the speed is more rider than gravity. I can’t say enough as to how dialed this is for back country rake and ride trails, especially on challenging rocky / rooty trails style stuff.
Attention to detail is excellent here, and clearly the product from someone who knows their stuff and is also generous with his knowledge. I expect to spend many years of great riding with this bike! Thanks Dave!
This bike is amazing. I was nearly turned off by the shipping costs to Australia but I'm so glad I pulled the trigger. It's really special.
Firstly, it's beautiful. I stared at the frame for a week before building it up! It's a work of art .
Secondly, the ride is phenomenal. The power transfer is next level, it climbs well, descends well, corners well and it's smooth. Was able to fit a 180mm dropper. I've raced XC on it, done some long rides on it and I'd happily take it bike packing.
Lastly, as others have said, D.T was great to deal with. In Australian, "a top bloke". Answered all of my questions promptly and friendly. Thank you!!
