Flaanimal 4.1

Flaanimal is a multi use steel adventure frameset designed and built around the themes of versatility and adaptability. Now in its 4th iteration, Flaanimal has been the product of non stop refinement and iteration since the day it was first designed. In its current 4.1 state we believe it to be one of the most feature rich and enjoyable steel framesets available today.

Flaanimal is meant to be built and ridden any way that you like. Each of its primary design details are intended to leave key decisions about function up to the owner. With large tire clearances, interchangeable dropouts, and completely configurable shifting and braking routing the frameset is not locked into rigid categories. As each rider’s personal style and tastes evolve Flaanimal is designed to evolve along with them.


Flaanimal framesets and a selection of pre-configured complete bikes — with your choice of wheel size — are available through this page. If what we have on offer here doesn’t quite fit your needs, or you’re not sure which type of build is best for you, click here then hit the “start a build” button, fill that form out, and we’ll get in touch with you.

Take a look at our build options lower on the page to get a sense of cost and then start with our build form below to get a conversation started with our build team.


Flaanimal 4.1


Flaanimal 4.1 steel adaptable adventure frameset with painted-to-match Spork 1.2.

Make mine a complete build:

Your Flaanimal will be fully assembled and tuned in-house so it’s ready to ride, then minimally disassembled for packing. You’ll have to reinstall the front wheel, seatpost, handlebars, and rear derailleur (on some bikes) when you receive it.

Click here for complete component specs in the Build Pricing section, below.

Click here for standard cockpit component sizing per frame size, listed below.

Choose your wheel size:

Pre-configured builds include Panaracer GravelKing SK tires in either 700 x 38mm or 650b x 48mm.

Dropper post & dynamo hub options:

– Available on complete bikes only.
– May require additional lead time to complete your build. We will get in touch if your lead time will be longer than typical.
– Dynamo hub option replaces the stock front hub on a Rodeo 2.0 Carbon front wheel.

Each tube profile is uniquely designed and balanced for weight and the strength requirements of an adventure frameset. The EC44 head tube, bottom bracket shell, and rear dropouts are machined to remove every ounce of un necessary material while leaving robust joining surfaces for strength. The rear triangle is optimized for drive side and non drive side loads and for the specific needs of the stainless steel Gates Carbon Drive frame coupler hardware. With frame weights in the 2000gr range for size 48 up to 2500 gr for size 61 we’ve been able to carefully create an incredibly strong frameset that can stand up to the rigors of road and off road riding. Our frameset weights are on par with the best in the industry while at the same time offering a more broad and adaptable feature set than any other frameset in this category. The Flaanimal 4.1 frameset is on average 800 grams lighter than the Flaanimal 3.0 frameset.[/vc_column_text][/vc_column][vc_column width=”1/2″ css=”.vc_custom_1514918729425{margin-top: 0px !important;margin-right: 0px !important;margin-bottom: 0px !important;margin-left: 0px !important;}”][vc_gallery interval=”3″ images=”7206,7205,7204,7203,7202,7201″ img_size=”large” onclick=””][/vc_column][/vc_row]

Just like Flaanimal, Spork is unique in the market in its feature set.

The downtube features four reinforced internal routing ports that are brazed onto the frame. Interchangable frame plugs allow each port to be used as an entry or exit point for brake routing, derailleur routing, di2 wiring, and even dynamo light routing. Routing exits near the bottom bracket and runs externally along the chain stays for mechanical and hydaulic builds. Di2 wires also have the option to be run fully internally on the frame to further streamline the appearance of the complete bike and to protect Di2 wires from the elements.[/vc_column_text][/vc_column][vc_column width=”1/2″][vc_gallery type=”nivo” interval=”3″ images=”7114,7113″ img_size=”medium” onclick=””][/vc_column][/vc_row]

  • Integrated full frame peg mount
  • Flaanimal 4.1 frames feature a T47 68mm threaded bottom bracket shell
  • Flaanimal 4.0 frames feature a BSA 68mm English threaded bottom bracket shell

  • Full electro dipped anti rust coating on inside and outside of frame before painting

Flaanimal geometry is unchanged from 3.0 to 4.1. Rodeo Labs does not design its bikes as gravel specific, we design bikes to be as widely adaptable to a broad range of riding conditions as possible from road, to gravel, to trail. Our geometry prioritizes the elimination of toe clearance across all sizes. Our geometry prioritizes high speed stability. Our geometry prioritizes bottom bracket clearance in rough, rocky terrain.

We are offering three new color options for Flaanimal 4.0. We loved the paint colors that we offered on 3.0 but we feel like that as a brand Rodeo needed to keep exploring with color no matter how good the 3.0 colors looked. For 4.0 we now offer the following colors:

Pine Cone Inspired by the palettes of 1970s camping gear, Pine Cone combines a deep chocolate / merlot main frame color with celeste rear seat stays and accents inside of the front fork. Orange type and cream accents round out the look for a truly distinctive frameset that will never, ever be mistaken for anything but a Rodeo Labs Flaanimal.[/vc_column_text][vc_gallery type=”nivo” interval=”3″ images=”7112,7124,7166,7165,7164,7163,7162,7161,7160,7159,7158,7137,7138,7136,7129,7130,7131,7132,7133,7125,7126,7127,7128,7135,7134,7101″ img_size=”medium” css=”.vc_custom_1514927075329{margin-right: 20px !important;margin-left: 20px !important;}”][vc_column_text css=”.vc_custom_1515018563453{margin-top: 20px !important;margin-bottom: 20px !important;}”]Bleaux Deaux Blue is the single most popular color on planet earth and the 3.0 Bleaux was the most popular Flaanimal color. It’s pretty safe to say we wanted to offer blue again, but we wanted to do it differently this time. For the main frame color we went with a deep navy color that keeps things classy and classic. For the accent color we went with a brighter complementary shade of blue. The combined effect is the most reserved 4.0 color offering, but one that is still distinctive in a crowded market of otherwise similar looking bikes.[/vc_column_text][vc_gallery type=”nivo” interval=”3″ images=”7172,7167,7178,7177,7179,7176,7175,7174,7173,7170,7169,7168″ img_size=”medium” css=”.vc_custom_1514927097300{margin-right: 20px !important;margin-left: 20px !important;}”][vc_column_text css=”.vc_custom_1514925800147{margin-top: 20px !important;margin-bottom: 20px !important;}”]Chocolate creamsicle We love the pop of an orange frame, but there is no way that we were going to make a frame that was all the way orange. It needed some contrast, so we combined a dark chocolate brown with the orange to make a color option that was both vibrant but also once again unique. On this frame the Flaanimal 4.0 lettering on the top tube is also a vibrant electric blue.
