Nitrous
Refined, Speed
Updated and True to Its Roots
The latest Nitrous keeps everything that made it great—now with smart improvements for even more performance:
- 3D-printed chainstay ½ yoke – Awesome tire clearance to 2.6” and fits up to a 38T round chainring
- Streamlined 3D-printed cable ports – Sleeker, smoother, and designed for hassle-free internal routing
- No changes to geometry or tubing—because when something rides this well, why mess with it?
Built for Modern Speed
- UDH-Compatible: Ready for SRAM Transmission or any derailleur from the last decade
- Multi-Port Internal Routing: Supports electronic or mechanical shifting and a stealth dropper post
- Progressive XC Geometry: Longer, lower, slacker—for a ride that’s both fast and confident
Why a Hardtail?
- Not every trail needs full suspension—and with more sanitized trails, a hardtail is faster and more fun
- More capable than a gravel bike when the going gets rough
- Lighter and more responsive than a full-suspension bike on flowy, rolling terrain
The Nitrous is refined for speed, efficiency, and control—ready to power through climbs, rail corners, and rip descents with precision.

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
I received the frame and upon opening the box it felt like I was opening the Ark of the Covenant. White doves flew out of the box, an aura exploded from the top of the box and the presence of frankincense and mir permeated. That may have all been in my mind but I swear it felt like that. The small details in the etching to the head tube badge makes it feel world class. Most importantly David himself going back and forth in email with me to make sure everything was what I needed was just one amazing experience. Maybe he is the Messiah?
This is an absolute home run from Turner Bikes, A beautiful sculpted custom titanium tube set packed with modern geometry and a lot more.
The build quality and all the detail exceeds the competition and you have to get your hands on this frame to truly appreciate it.
I couldn’t be more thrilled with the Nitrous and the outstanding customer service from the legend David Turner! He truly cares about his customers!
Turner Bicycles changed the Game. Get 0ne!
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.
