YETI ASR - Mountain Bicycle Manual

THE LOWDOWN ON THE ASR AND ITS FEATURES

FRAME FEATURES

1. ACTIVE SUSPENSION RACE SUSPENSION SYSTEM
   The ASR delivers 115mm of rear wheel travel with our iconic ASR suspension technology. Utilizing a flex-stay pivot point and lightweight hardware throughout, the ASR provides efficient pedaling performance while still smooth and supportive when going gets rough.
2. HIGH MODULUS CARBON FIBER MAIN FRAME AND SWING ARM
   High modulus carbon is hand laid to create our TURQ Series frames. That same stiffness and efficiency can also be found in our carbon series frame sets.
3. LIGHTWEIGHT SUSPENSION LINKAGE AND HARDWARE
   The TURQ series ASR frame utilizes a forged 7075 aluminum rocker link to provide stiffness in a lightweight package. Additionally, titanium shock mounting hardware helps keep the weight down and hardware secure in the most demanding conditions.
4. RATTLE-FREE CABLE PORT ASSEMBLY SECURES CABLES AND HOSES TO PROVIDE A SILENT RIDE
   The ASR is designed with clamping cable ports to insure a quiet ride, reduced cable movement and clean aesthetic. The ports are configurable so you can choose cable or wireless components without leaving behind open housing ports.
5. INTEGRATED 41MM / 52MM TAPERED HEAD TUBE
   Using an integrated head tube design on the ASR allows for a larger head tube with more area, which results in increased stiffness, and lower overall ride height without compromising any performance.
6. TWO WATER BOTTLE MOUNTS
   The ASR is able to fit two water bottles inside the main frame to keep you hydrated on those extra big days.
7. CUSTOM DOWN TUBE PROTECTOR AND RIBBED CHAIN GUARDS TO DECREASE CHAIN SLAP NOISE
   Custom seatstay, chainstay, muck fender, and down tube guards keep the ride quiet while protecting the frame.
8. INTEGRATED AXLE AND UNIVERSAL DERAILLEUR HANGER SYSTEM
   Dedicated 12 x 148 boost dropouts with SRAM's universal derailleur hanger (UDH) provide strength, stiffness and easy hanger and wheel installation.
9. CUSTOM TUNED REAR SHOCK
   We develop custom suspension tunes from the ground up here in Golden, CO to optimize suspension performance to perfectly compliment the ASR suspension kinematics. For help setting up your suspension, please visit our Shock Setup Guide.

10. CUSTOM INTEGRATED CHAINGUIDE
    The ASR is equipped with an ultra lightweight custom integrated chainguide for worry free chain retention in the roughest of terrain.
11. CABLE ROUTING FOR INTERNALLY ROUTED LONG DROP SEAT POST
    This may be an "XC" bike, but it has the soul of an enduro machine. We know you'll be riding it with a dropper post.

FRAME ASSEMBLY

YETI TIPS
Make sure your tools are in good condition. A worn allen key can round the hex on a bolt not allowing for proper torque.
It is important to prep all bolt threads. The instructions denote whether to use a Loctite compound or grease. Please ensure all prep call outs are followed.

Failure to follow prep instructions could lead to serious frame issues.

Service on Yeti bicycles requires special knowledge and tools. Yeti Cycles recommends that all service and repairs be performed by an authorized Yeti Dealer.

   Slide rear triangle assembly onto main pivot. Lightly grease shaft of the Keyed Main Pivot axle (3.2), apply Blue 243 Loctite to the threads of the Main Pivot Screw (3.3) and secure.
   Torque: 15 Nm
   
   Ensure the Flats on the Keyed Axle (3.2) are aligned with the Flats in the Front Triangle. DO NOT force installation. A 5mm allen key can help rotate the axle in the frame if needed to align the axle, but do not use this hex to tighten or loosen this bolt.
   
7. Place 2x Race Extenders (3.9) onto the lower bearings in Link Assembly (3.1). The side of the race extender that has the raised smaller diameter should fit against the bearing, allowing the flat side to rest against the carbon. Lightly greasing under the flange of the race extnders will help hold them in place during install.
   Rotate Rear Triangle and Link together, lining up SS Pivot bores and slightly flexing the seatstay if needed. The link will have to be rotated forward in order for the SS pivot screws to clear the seat tube.
   USE CAUTION to not scratch the seat tube.
   Lightly grease shaft and apply Blue 243 Loctite to threads of Seat Stay Pivot Screws (3.6). Grease seatstay frame cavities where Keyed Nut (3.8) will be installed.
   
8. Install 2x Seat Stay Pivot Screws (3.6) from the inside of the Link and partially into the Rear Triangle. Place 2x plain Keyed Nut (3.8) into the Rear Triangle.
   While supporting the rear triangle so the link does not contact the seat tube, use a wrench from the outside of the Swingarm to begin tightening in the "left-hand" direction (this is still a standard thread, but installed from the inside), tightening the SS Pivot Screw and Keyed Nut.
   Torque: 15 Nm
   
   QC CHECK
   Cycle rear triangle through to make sure motion is smooth.
   Take precaution to make sure link does not contact seat tube.

10. Install Universal Hanger (3.15) to the frame. Do not use grease. Note that the hanger cap bolt is REVERSE THREADED.
    Torque: 25 Nm
    

BEARING PRESS ASSEMBLY

LINK BEARING PRESS

1. Press both upper bearings into the link using a 10x19mm arbor. Support space between the tabs on the link while pressing bearings to ensure the link does not bend or get damaged.
2. Clean outer bearing race with alcohol and apply bearing retaining compound (Green 609 Loctite) to both lower bearings.
3. Press both lower bearings into the link using a 10x19mm arbor.

MAIN PIVOT BEARING PRESS

1. Press one bearing at a time using a 12x24mm arbor
   NOTE: Use caution when contacting the inside carbon face to avoid any damage to the paint. It is not advisable to press both bearings in at the same time.

CABLE ROUTING SET-UP

NON DRIVE CABLE ROUTING

FRONT TRIANGLE - REAR TRIANGLE VIEW FROM BOTTOM

DRIVE SIDE CABLE ROUTING

1. Route brake cable first through the non drive side port in the rear tri, cable routing grommet, and the top port in the headtube.
2. If applicable route the rear derailleur cable through the drive side rear triangle port, cable routing grommet, and the bottom port in the headtube.

Cable routing is most easily done with the seat stay pivots assembled and the main pivot free to allow the rear tri to swing away from the front triangle.

DROPPER POST ROUTING SET-UP

1. With a 3mm allen wrench, remove the lower access door.
   
2. Install your seatpost housing into the drive-side head tube port, pushing until it exits near the downtube cable port access hole.
   
3. The hole under the downtube protector provides an access point to use your finger to help push the housing around the bend in the frame up into the seat tube.
   
4. While pushing the housing into the head tube port, continue guiding the cable up the seat tube through the access hole until the housing exits the seat tube.
   

CABLE LOCKOUT ROUTING SET-UP

1. Remove rubber port grommet from frame.
2. Route cable housing through the frame and out of the top port in the headtube on drive side.

DROPPER POST INSERTION GUIDE

Droppers are an essential tool for the modern mountain bike but proper clearance checks are required before heading out for your first ride.
The key checks are as follows:
Ensure your dropper is short enough to fit into the seat tube without interfering with the frames structure but you are still able to achieve your desired BB-Saddle measurement. See the max insertion depth chart to confirm this distance for wired and wireless posts.
There are some scenarios where you can fit a longer dropper in your frame but when you drop your dropper the saddle or battery for AXS posts could interfere with your tire during a suspension compression. See the Min BB-Saddle at full drop to confirm this distance.
Always perform a final check to ensure your post is installed to at least the minimum insertion line. Also, compress the dropper and suspension, let the air out of your shock, to ensure there is no tire interference to the saddle or AXS battery at full bottom out.
We strive to spec out dropper lengths to provide the maximum drop for the highest percentage of our riders. There is a wide range of saddle heights for every frame size. There is a possibility saddle height could fall outside of this range. A small percentage of customers might find they require a shorter or longer post given their saddle height.
Please ensure you check the minimum dimensions in the below tables before going for your first ride. Failure to do so could result in tire to saddle rub or tire to battery contact for AXS posts.
Please confirm both of these measurements, they are both required to ensure proper dropper fitment.
If you have any questions, please contact Yeti or your local bike shop.

*These measurements are only for cabled droppers. Please make sure if you have a wireless post you confirm that there is not any interference of the tire hitting the battery when the post is fully dropped and the suspension is fully compressed.
**If you go lower than the listed minimum, you run the risk of tire to saddle interference.

*Subtract 34mm for a cabled dropper to accommodate housing bend angle.

FREQUENTLY ASKED QUESTIONS

WHAT IS THE DIFFERENCE BETWEEN THE TURQ AND CARBON SERIES ASR?
TURQ Series bikes are manufactured with the highest quality and best-performing carbon fiber available and offer the perfect balance of stiffness, durability, and compliance. The result is a bike that feels smooth, solid and aggressive. Carbon series bikes use a modified carbon fiber layup of our TURQ Series bikes. By using different materials and tweaking the fiber layup, we are able to make a more aggressively priced carbon high-performance mountain bike while maintaining the strength and stiffness of its higher end sibling. The carbon series ASR weighs a bit more, about 160g for a frame.

CAN I REPLACE OR MODIFY ANY YETI FRAME PARTS ON MY ASR?
All replacement frame parts for your ASR can be found through your local dealer or on our webstore. Only genuine Yeti parts should be used when replacing any parts on your frame. We know there are a lot of aftermarket products out there that seem legit but we do not have the ability to qualify and ensure all of these products are safe to use on our frames. If it is found that any frame part has been modified or replaced all warranties will be voided and all liability will be assumed by the customer.

CAN I CHANGE OR UPGRADE THE SPEC COMPONENTS ON MY ASR?
There are many options in aftermarket parts to upgrade or personalize your bike. Some parts are standardized, especially from the big brands like Fox, Shimano, SRAM etc. You should always confirm with a professional mechanic that your parts are the correct standard and correctly and securely mount to your bike without any interference or play. Pay special attention to all the bike's standards and check the fit before use.

CAN I USE AN ANGLESET ON THE ASR?
The ASR was designed with an integrated headset which has the headset cups molded into the frame so you can easily drop the bearings into the cups. There are some aftermarket anglesets available for this style headset however the frame was not tested for the use of these and therefore should not be used. Yeti's warranty will be voided if it is found an angleset was installed on the frame and all liability will be assumed by the customer. See "What travel fork is the ASR designed to use" for more information.

WHAT TRAVEL FORK IS THE ASR DESIGNED TO USE?
The ASR is designed to run a 120mm travel fork. We tested this frame to 20mm over the spec fork. So if you're feeling the need to beef up the fork you can run up to a 140mm fork no problem. Bottom line - max axle to crown measurement of 555mm. Increasing your fork travel will slacken the head angle and seat tube angle and raise the bottom bracket. Running a shorter fork is fine too if that suits you. Shortening the fork will steepen the head angle and seat tube angle and lower the bottom bracket. For more geometry information, check out the geometry section.

HOW BIG OF A TIRE CAN I FIT ON THE ASR?
The short answer is the ASR can accept up to a 2.4" tire. There is great tire clearance on the ASR but tire sizes vary widely by manufacturers, so it is hard to give a number that works for all brands.

CAN I FIT A WATER BOTTLE INSIDE THE FRONT TRIANGLE?
Yes, all frames have mounts for water bottles on the seat tube and down tube. We designed the ASR to accommodate at least one standard sized water bottle inside each front triangle. Our recommended max bottle capacity per size are outlined below, but exact fitment may depend on your specific shock, cages, and bottles of choice.
XS: 21oz on seat tube, 15oz on down tube
S-XL: 21oz on seat tube, 24oz on down tube
We recommend using Yeti's 15oz Hot Lap bottle for any tight-clearance fitment and a side-entry cage for easiest access.

WHAT CRANKS AND BOTTOM BRACKET CAN I USE ON THE ASR?
The ASR bottom-bracket standard is BSA 73mm and only wide "q" factor cranks are compatible. It is readily compatible with Shimano, SRAM, and RaceFace cranks, but a fit check is required for other brands.

WHAT REAR WHEEL AXLE FITS ON MY ASR?
The ASR is designed to work exclusively with SRAM's Universal Derailleur Hanger at 12x148mm spacing. This axle has a thread pitch 12x1.0 and a length of 172mm. Note that this axle is only compatible with frames specifically designed with the Universal Derailleur Hanger.

WHAT TYPE OF HEADSET DOES THE ASR USE?
The ASR uses an Integrated 41mm/52mm tapered headset. This system allows for the headset bearings to be contained inside the head tube for an overall lower ride height, more simplified installation, and increased stiffness.

HOW BIG OF A ROTOR WILL FIT ON THE FRAME?
The ASR has a direct mount rear brake tab and can run a 160mm rotor without the need for a brake adaptor. With the use of a brake adaptor the frame can accept up to a 180mm rotor.

CAN I RUN A STEALTH SEATPOST DROPPER ON THE ASR?
Yes. The ASR has routing options for stealth only.

WHAT CHAINLINE WAS THE ASR DESIGNED AROUND?
The ASR was designed around a 55mm Boost chainline. Depending on the crank and chain ring configuration you can run other chainlines but you will have to do a clearance check first. Minimum clearance from the chainring teeth to the chainstay is 3.5mm.

WHAT IS THE MAX SIZE SINGLE-CHAINRING THAT FITS ON THE ASR?
Without getting too technical, the max chainring size depends on the crank chainline and the chainring shape. Minimum clearance from the chainring teeth to the chainstay is 3.5mm.

• Shimano / SRAM 55mm chainline Boost cranks: 36t (XS-S)/38t (M-XL)
• Minimum Chainring Size: 28t (All sizes)

Confused? Ask your local dealer or call us 303.278.6909.

DOES THE ASR HAVE ISCG MOUNTS?
No. The ASR comes with an optional integrated chain guide device if you want to increase chain security.

WHAT TYPE OF SHOCK DOES THE ASR USE?
The ASR uses a 190 x 40mm shock. The shock can be configured with or without remote lockout capability. 40mm is the max designed shock stroke, and longer strokes are prohibited.

WHAT TYPE OF SHOCK HARDWARE DOES THE ASR USE?
The ASR uses M8x20mm front hardware and M8x30MM rear hardware (standard eyelet hardware or bearing-mount).

CAN I PUT A COIL SHOCK ON MY ASR?
No, the ASR will not fit a coil shock due to sizing constrictions and limited frame clearance in the bike's link.

WHAT PERCENTAGE SAG DO YOU RECOMMEND FOR THE ASR?
We would advise starting with 30% sag, or 12mm of shock stroke for optimal pedaling efficiency and terrain compliance. Be sure to set your sag at your normal riding weight, gear included. Feel free to venture slightly above or below 30% to suit your personal preference.
Visit our shock set up page to help set up your suspension, https://shocksetup.yeticycles.com/calculator

WHAT SIZE SEAT POST DOES THE ASR USE?
The ASR uses a 31.6mm seat post.

WHAT SIZE SEAT COLLAR DOES THE ASR USE?
The ASR uses a 36.4mm seat collar. T-Series frames utilize the Bike Yoke Squeezy clamp and the paint masking on the seat tube is specific for this seat collar. Alternate seat collars could damage paint.

WHAT IS THE WARRANTY ON MY ASR?
The ASR has a LIFETIME manufacturer's warranty.

WHAT IS THE LONGEST TRAVEL DROPPER POST I CAN RUN ON THE ASR?
This is mostly defined by your inseam. There is no frame limitation, so in theory, you can run any travel as long as you are above the minimum insert mark and you are not so low your tire rubs on your saddle. Your local Yeti dealer can help you sort this out. We run 125mm drop on XS-SM frames, 150mm on MD-XL with the Fox Transfer SL Dropper Post. Other dropper post models can go up to 240mm but always check the fit guide in the owner's manual to ensure alternative dropper models will fit correctly.

HOW DO I SETUP MY ROCKSHOX FLIGHT ATTENDANT SUSPENSION?
Please visit SRAM.com or download the SRAM AXS mobile app for information on tuning your Flight Attendant equipped bike.
SRAM also has video tutorials, see the link below.
https://www.youtube.com/playlist?list=PLIVKlyOSFFsI8XovLz0w50hXApYH2GLFj

CAN I TAKE OFF THE SUSPENSION REMOTE LOCKOUTS ON MY TURQ-SERIES SPEC?
Technically, you can remove the remote lockouts from your fork and shock but you will no longer be able to switch between the 3 positions, Open/Pedal/Lock, and it will default to the Open position. If you prefer the 3 position controls to be on the fork and shock then you need to replace the entire fork or shock with the lever adjust versions.

WHAT IS THE MAX SYSTEM WEIGHT FOR THE ASR?
The max system weight is the the total allowed weight of the bike, meaning rider + gear + bike weight. This is driven off of the ratings of componentry. Be sure to check the specific components on your unique build. Our spec builds are driven by the max system weight of the wheels: M1900 and XM1700 are rated to 120kg; XRC1200 are rated to 110kg.
