Traildonkey 3.1 is our premiere adventure bike platform. Originally created to transport us across Colorado’s roads and trails in 2014 the bike has since evolved into one that that has raced and prevailed at the highest levels of gravel racing and bikepacking worldwide. Silk Road Mountain Race, Tour Divide, Unbound 200 and XL, Mid South, Atlas Mountain Race, Transcontinental, Arkansas High Country Race and more incredible races are all on the podium achievements list of this capable bike. And for those that don’t race, Traildonkey 3.1 is simply a capable, fun platform to build into whatever suits your personal riding goals.
Our frame inventory and parts availability have improved significantly in recent months. Many build configurations for frames that show as in stock can ship as quickly as 3-5 days from ordering. Framesets that show in stock ship within 24 hours. Custom finishes and custom build specs add to that time, but if you are in a rush to get a bike just shoot us a note at email@example.com and we can put hot sauce on a build for you.
Frameset vs Complete Bike
Framesets and complete bikes may be ordered through a simple checkout process below. If you would like to customize your build we are happy to adjust any standard build that we make with your request to make your bike fit and perform better for you based on your goals. To get started with a custom build please purchase your frameset below to reserve the frame then complete the custom build form with any info you can provide. We will get in touch soon after and walk you through the rest of the process.
Frame colors will closely match the gallery images but can shift depending on viewing device.
Build Pricing — Specifications — Geometry
What if there were no bicycle categories? What if nobody had told us that we needed a different bike for each day of the week and every different riding surface?
What if a bike was neither good nor bad at anything? What if, instead, it was merely a capable tool for testing yourself and proving your own mettle?
To Rodeo Labs these are not abstract questions. They are the inspiration by which we design and engineer our premiere bike: Traildonkey 3.1.
TD3 is a platform on which a rider can build a bike of supreme function and versatility. The spectrum of its abilities ranges from pavement to singletrack to gravel, and everything in between.
The Traildonkey Story
Now in its third major iteration, Traildonkey has upped its capabilities to match our ever growing ambitions. Since 2014, our eyes for rugged conditions have only gotten bigger and the punishment we’ve subjected the bike to has only gotten more severe. While we wanted to create a more capable bike, we did not however want to turn Traildonkey into an overbuilt, drop bar mountain bike. We wanted to stay true to the original principles of the bike which required that it feel at home in the intensity of a competitive road group ride, a 200 mile gravel race, a winding ribbon of singletrack, or a multi-day bikepacking trip.
TD3 is not only an exercise in increasing capabilities, it is also an exercise in restraint. The lines of the frameset have become more elegant and the execution of the details has become more focused.
The entire 3.0 rear triangle, from the seat tube back, has been completely redesigned. Over the years we’ve formed some strong opinions on what makes a great bike. We’ve woven those ideas into this frameset. High on our list of improvements for TD3 was increased tire clearance. Our newest Donkey has that in spades. On Rodeo 650b rims with a 24.5 mm ID a 2.1″ tire will fit on TD3. On Rodeo 700c rims with a 24mm ID a 45mm tire will fit on TD3.*
More Capable, Just as Sleek
In order to achieve greater tire clearances, extensive and careful shaping was required in the design of the rear triangle. Pronounced asymmetry between drive and non-drive side stays can be clearly seen in our design. We also took the opportunity to refine and simplify the dropout design, brake housing routing, flat mount brake mounts, and derailleur housing routing. When wireless eTap shifting is used on TD3, no residual housing protrusions are seen on the frame. This results in a beautiful, minimal aesthetic. Both 2x or 1x drivetrains work equally well on TD3 and when 1x drivetrains are used the front derailleur mount can be removed. Rack and fender mounting eyelets are once again standard on TD3 on both the frameset and fork and now feature larger clearances for fender / tire combinations.
TD3 features extensive mounting options for long-distance travel and bikepacking. On the rear triangle we include eyelets on the upper stays and just above the rear thru axle dropouts. On the main triangle, the frame features two bottle mounts on the main triangle as well as one mount beneath the lower down tube. The top tube includes two mounting points for top tube bags or a standard water bottle cage.
Built for the Long Haul
TD3.1 doesn’t pay lip service to strength and durability. When we upped the technical capabilities of the bike we were careful to also increase strength in critically stressed areas. In both lab and real-world testing TD3 is leaps and bounds stronger than any previous Traildonkey frameset. So many modern bikes are engineered with a disproportionate emphasis on light weight. We believe that the arms race to shave grams has resulted in a reputation for carbon framesets as fragile, almost disposable. With TD3 we have created a frameset that will reliably serve its owner over the long term and we back it with a lifetime warranty. Our engineering culture is to integrate an excess of strength into the frameset; to create a frameset that will stand the test of time on road, gravel, and trail.
Traildonkey is constructed with Toray T800 carbon for high strength and high performance in real world use. Each frame is constructed entirely by hand in Taiwan by a manufacturing partner with over 30 years of high-end carbon manufacturing experience.
T47 Bottom Bracket
Rodeo was one of the first bike manufacturers to standardize all of our framesets around the threaded T47 bottom bracket standard. The removable bottom bracket cover on TD3.1 features a drain hole which allows water to escape the frame in wet conditions. The result is a quiet, low-maintenance bottom bracket experience for every owner. It was one of the best spec decisions that we’ve ever made. The threads allow reliable, quiet operation over the life of the bike, and the 47mm shell allows compatibility with all crankset spindle diameters while also leaving room for internal Di2 and dropper post routing.
The Traildonkey 3.0 used the 2.0 series Rodeo Spork fork. Spork 2.0, which we designed for Traildonkey 3.0, checked all of the functional boxes, but the visual profile of the fork was out of balance. Enter Rodeo Spork 3.0. Spork 3.0 carries forward the key features of Spork 2.0 such as full carbon construction, internal dynamo routing, adaptable axle spec, and configurable eyelet options, and brings it all together in a slimmer, lighter package. Traildonkey 3.1 will change to 12×100 front thru axles but retain the ability to convert to 15×100 if your build requires it.
Traildonkey 3.1 and Spork 3.0 were developed in tandem to work together as a single system. Spork 3.0 matches TD3.1 tire clearance and adds additional versatility in the form of integrated dynamo hub, headlight, and USB stem cap integration. Spork 3.0 features mid-leg eyelets allowing expanded water and 12.5kg of gear carrying capability. Spork also features two axle eyelets on the end of each leg and an optional offset eyelet hardware kit, which allow for a massive range of rando racks, low rider racks, fenders, and combinations therein.
Limited Lifetime Warranty
Traildonkey’s lifetime warranty covers the performance and durability of the frame and fork and warrants them against deficiencies in design, engineering, and construction to the original owner of the frameset as long as they own the bike. Our owners are family and we take care of them long term. Read our full warranty terms here.
