YETI SB5+ Mountain Bicycle Manual

THE LOWDOWN ON THE PRODUCT AND ITS FEATURES

1. SWITCH INFINITY TECHNOLOGY PATENTED SUSPENSION SYSTEM
   The SB5+ delivers 5 inches (127mm) of travel with our patented Switch Infinity Technology. Efficient pedaling performance while still smooth and continuous when the going gets rough.
2. HIGH MODULUS CARBON FIBER MAIN FRAME AND SWING ARM
   High modulus carbon provides a stiff, strong and light weight chassis.
3. WIDE REAR TRIANGLE CLEARANCE FOR UP TO 3.0" TIRES
   The SB5+ is designed to accommodate up to a 3.0" tire. The common "plus" tire sizes are 2.8" and 3.0."
4. ELEVATED CHAINSTAY FOR RIGIDITY AND CLEARANCE
   The SB5+ uses elevated chainstays to accommodate up a 3.0" tire and maintain clearance for the drivetrain without compromising performance.
5. COLLET AXLE SYSTEM ON PIVOTS REDUCES BEARING WEAR
   Colleted pivot axles help create a stiff interface between the front and rear triangles of the frame. Custom Enduro Max sealed bearings keep things moving freely at the pivots.
6. ISCG 05 CHAINGUIDE MOUNTS
   ISCG 05 chain guide mounts are included on the SB5+ if case you want to go for some extra drivetrain security in the rowdy sections.
7. TAPERED INSET HEAD TUBE (44MM/56MM)
   Using our inset (44mm x 56mm) head tube on the SB5+ allows for a larger head tube with more area, increased stiffness, and lower overall ride height without compromising any performance.
8. CUSTOM CHAINSTAY AND DOWNTUBE PROTECTION
   Custom guards on the seat stay, chain stay and down tube keep things quiet while riding and protect the frame.
9. INTERNAL CABLE ROUTING
   The SB5+ features internal routing for all cables, making the bike quiet and clean looking as well as reducing cable rub on the paint.
10. INTEGRATED AXLE AND DERAILLEUR HANGER SYSTEM
    Dedicated 12 x 148 Boost dropouts and integrated hanger with axle threads for strength, stiffness, ease of hanger and wheel installation.
11. FOX SUSPENSION (7.875" X 2.0")
    The SB5+ uses a 2.0 inch stroke, 7.875 inch eye to eye Float EVOL shock, by Fox Racing Shox.
12. 27.5+ OR 29" WHEEL COMPATIBLE
    Our builds are spec'd with 27.5+ wheels but that doesn't mean you can't throw a set of 29" wheels on the SB5+.

Make sure you review and understand the warnings, instructions, and content of this manual and accompanying manuals for your bicycle.

Technological advances have made bicycles and bicycle components more complex and the pace of innovation is increasing. It is impossible for this manual or the accompanying manuals to provide all the information required to properly repair and/or maintain your bicycle. In order to help minimize the chances of an injury, it is critical for you to have work performed by an authorized Yeti retailer.

GEOMETRY

*All measurements are in millimeters

KEEP YOUR PRODUCT FRESH AND CLEAN

OVERVIEW

Following these guidelines will help maintain the performance of your bicycle and prevent more serious problems from arising. It is important to remember that service intervals can vary depending on climate, trail conditions and riding frequency. If you are unsure about working on your own bicycle, contact your authorized Yeti Dealer for more information on general bicycle maintenance.

SCHEDULE

TORQUE

Yeti strongly recommends using a torque wrench when assembling your frame. Torque specifications for individual parts on the SB5+ are listed below, as well as in the step by step assembly instructions later in the manual. For general bicycle maintenance please consult the torque specifications of the component you are adjusting.

KEY TORQUE SPECS

SHOCK SETUP

YETI TIPS

Inspect your shock for any visible damage. If oil is leaking or you notice any damage to the surfaces or seals, please contact the Fox Racing Shox service center for repair at 800. FOX.SHOX or your local bike shop.
Shock set-up can fluctuate greatly based on the rider. The set-up guide is intended as a base line to get the rider started. Experiment with your settings to find the set-up that works best for you.
We recommend starting out with 25-30% sag, which is 13-15mm of shock stroke.

TOOLS NEEDED

• Shock Pump
• Metric Tape Measure

QUICK START GUIDE

*All clicks are counted counter-clockwise, rotating from the all the way "in" or clockwise dial position.

AIR PRESSURE

The main air spring controls sag. For the SB5+ to ride properly it is important to setup the shock with the correct amount of sag. The ballpark pressure to get you started should be 5-10 psi below your rider weight. You will have to cycle the shock 10-15 times to equalize the EVOL chamber before you get a correct psi reading. Remove the pump form the shock while doing this.

SAG

The SB5+ works best with 15MM (+/- 1mm) of measured sag. To increase sag, reduce the main spring air pressure. To reduce sag, increase the main spring air pressure. Remember to cycle the shock 10-15 times to equalize the EVOL chamber before measuring. Now, with a friend supporting you, get on the bike with your normal riding gear on and sit in a neutral position. Sit still on the bike and have your friend slide the shock's O-ring up to the seal. Step off the bike gently and measure as seen below.

REBOUND

Rebound is adjusted using the red knob. Clockwise will slow the rebound, counter clockwise will speed it up. Rebound needs to be tuned to rider preference and air spring pressure. Too slow and the bike will feel like it is not ready for the next bump. Too fast and it will feel like the bike is bucking you off after an impact. Play with this adjustment a bit and get a feel for what it does.

COMPRESSION

The blue lever has 3 positions: Open, Medium and Firm. For our bikes, unless you are on pavement on the way to the trail, we recommend using the "open" setting. The Switch Infinity design will do the rest!
Low-speed compression is adjusted in the "open" position, using the black tabs and has 3 positions. 1 is wide open, 3 is more firm. This adjustment is subtle.

DERAILLEUR HANGER INSTALL

YETI TIPS

NOTE: The hanger cap is REVERSE THREADED. Be careful not to strip out the Hanger tool faces. The cap is marked with a tighten direction arrow.

Inspect the frame around the hanger seat for any suspicious damage any time you replace a hanger, especially if you are replacing it due to damage.

TOOLS NEEDED

• 6mm Allen key
• Grease

HANGER

Lightly grease the outside surface of the hanger where it interfaces with the frame. The hanger will fit into its space on the inside of the swing arm and should press easily into the frame.

HANGER CAP

Lightly grease the threads on the hanger cap. The hanger cap REVERSE threads into the hanger from the outside of the swing arm. Hand thread the cap into the hanger making sure that the threads mesh correctly.

TIGHTENING

Using a 6mm allen key, tighten the hanger cap into the hanger. REMEMBER, it is REVERSE THREADED. Follow the "Tighten" arrow on the cap. Finish tightening with a torque wrench if available.
*Torque to 80 in/lbs (9Nm)

CABLE SETUP

The SB5+ uses internally routed full length cable housing. By using full cable housing, we have eliminated break points in the line of your shifter housing. This allows for better overall shifting performance by reducing the entrance of unwanted elements such as sweat and sediment. By routing that housing internally we add to the protection from the elements and clean up the lines of the bike. No more zip ties to snag your shorts on and no more loose housing rattling around on your paint.
Do not remove any of the housing guide tubes that are installed in your new frame's front triangle. They will be used to pull your housing through the frame. If you are replacing used housing, use the old housing to pull your new housing through the frame.
If you don't have the guide tubes or old housing you can fish the housings through the frame, but it will be much easier to use an internal cable routing tool.
The SB5+ Rear triangle uses internal carbon tubing in the chain stay to route the cable housing and does not need a guide tool to thread.

The failure to properly route shifter housing can cause malfunction of the shift mechanism and unexpected shifting of gears.

REAR BRAKE AND DERAILLEUR

Your rear brake and shifter housing should run parallel around the left side of the head tube. Run the shifter housing and the brake housing into the individual ports at the head tube and thread them down into the down tube toward the exit ports just in front of the Infinity Link.

The shift housing comes out of the port on the drive side and goes immediately into the guide eyelet before gently curving up into the bottom of the chain stay. The brake housing does the same on the non-drive side.

NOTE: Use rubbing alcohol to help the housing pass through the grommets in the front triangle as you thread it through the frame.
Starting at the back of the bike and working forward will be necessary for some brake systems.

REAR DERAILLEUR

The rear derailleur housing will exit the swing arm via the port on the side of the seat stay right in front of the rear derailleur. Create a gentle curve to the derailleur and adjust to the manufacturers specifications.

REAR BRAKE

The rear brake housing exits the swing arm on the inside of the chain stay and goes directly up to the caliper. If your caliper allows, adjust the housing attachment angle to reduce the bend in the cable as much as possible.

INTERNALLY ROUTED SEAT POST

The SB5+ is designed to use an internally routed dropper post. The housing should be routed from the post forward. Guide your housing through the seat tube and into the down tube. Use the guide tube installed in the frame, or use the old housing if you are replacing the line on a used bike. The line should exit the down tube at the head tube on the drive side and curve around the head tube to the lever on the left side of the bar. If you are mounting your lever on the right side, you would simply route that housing over to the right. If you do route to the right we recommend placing some clear vinyl in front of the port to prevent cable rub.

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.
Torque settings are listed throughout the instructions. It is important to prep all bolt threads. The instructions denote whether to use a Loctite compound or grease.

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

TOOLS NEEDED

• 2.5mm allen key
• 5mm allen keys
• 4mm allen keys
• 10mm allen key
• Guide pin tool (Or two)
• Torque wrench
• Grease
• Blue (242) Loctite

1. All the parts you'll need to get your SB5+ frame assembled. Please refer to the exploded view later in this manual for more information.
   
2. Place washers (300030214) over the Infinity Link attachment bolts (300030057) and blue LocTite 242 to the threads. Insert the bolts in the frame and hang the black Infinity link spacers from them as shown above. Be sure the flat surface of the spacer is flush with the opening.
   
3. Insert the Infinity Link from the non-drive side. The Infinity logo should be on top and the Fox logos facing the non-drive side. Rock the link into place capturing the black fitting washers. Make sure that they have not slipped or rotated. The flat end of the fitting washers must be facing the opening in the frame and they must nestle into the Infinity Link stanchions.
   
4. While holding the link in place lightly tighten the bolts. You want them to snug so that the link does not move and so that the fitting washers are fully captured, but don't try to torque them by hand! Finish the job with a torque wrench.
   *Torque to 12 Nm
   
5. Lightly grease the bearing surfaces on your link.
   
6. Place the bearing race extender washers (300020049) on the lower link bearings. There should be just enough grease there to hold the washers in place.
   
7. Insert the lower end of the link into the frame with the bearing race extending washers in place. Gently rest the link upright in the frame.
   
8. Using one hand, align the link and press the lightly greased pivot axle (300040483) through. This will hold the link in place while you prep the pivot axle nut. (NOTE: Ignore the Loctite in the image, use grease)
   
9. Insert the collet axle nut (300030287) in the corresponding keyed hole and thread the axle in using a 5mm allen wrench. This acts like a headset and is meant to preload the bearings.
   *Torque: 3 Nm
   
10. Grease and install the well greased lower link collet wedge. (300040486) Tighten with a 4mm allen wrench and finish with a torque wrench.
    *Torque: 8 Nm
    
11. Your lower link pivot is now complete. Wipe any excess grease from the pivot axle area now and double check your torques. This is more difficult later in the process.
    
12. Grease the main pivot collet axle (300040485), including the threads.
    
13. Slide the swingarm over the infinity link and insert the main pivot collet axle from the non drive side. You may need to use a guide pin from the drive side to help align the bearing spacer in the link.
    
14. Insert the lightly greased main pivot axle nut (300030285) into the corresponding keyed hole in the swingarm and thread the main pivot collet axle into it. Using a 10mm allen wrench, tighten the main pivot collet axle.
    *Torque: 3.5 Nm
    
15. Place the bearing race extender washers (300020049) on the upper link bearings. There should be just enough grease there to hold the washers in place.
    
16. Grease the upper link pivot collet axle (300040484). Push the pivot axle through the swingarm and the upper link bearings from the non drive side. You may want to use a guide pin to help align the bearing spacer. (NOTE: Ignore the Loctite in the image, use grease)
    
17. Insert the lightly greased upper link pivot axle nut (300030286) into the keyed hole in the swingarm and, using a 5mm allen wrench, thread the pivot axle into the nut. Using a piece of foam or bubble wrap behind the link will help protect your paint until the shock is installed.
    *Torque to 3 Nm
    
18. Grease and install the main pivot collet wedge with a 5mm allen wrench. Be sure to grease both the threads and the collet wedge.
    *Torque to 14 Nm
    
19. Grease and install the upper link collet wedge with a 4mm allen wrench. Be sure to grease both the threads and the collet wedge. *Torque: 8 Nm
    
20. Slide the rear of the shock into the swingarm, align the shock eyelet and secure with a guide pin. (200020118)
    
21. Align the front shock eyelet to the mounting points on the front triangle and secure with a guide pin.
    
22. Place the 8.5mm washer (300030069) on the front shock mounting pin (300030262) and lightly grease the pin shaft.
    
23. Slide the shock mounting pin over the guide pin and push it through the frame and the shock.
    
24. Place the 6.5mm washer (300030062) over a Male Ti bolt (300030151). Apply Blue LocTite to the threads. Using two 5mm allen wrenches tighten the male bolt into the shock pin.
    *Torque to 7 Nm
    
25. Tighten a male Ti bolt (300030151) into the rear shock pin (300030288) ensuring that it is fully threaded into the pin. Slide a 8.5mm washer (300030069) over the pin and lightly grease the pin shaft.
    
26. Slide the rear shock pin over the guide pin and push it through the swingarm and shock.
    
27. Place the 6.5mm washer (300030062) over a Male Ti bolt (300030151). Apply Blue LocTite to the threads. Using two 5mm allen wrenches tighten the male bolt into the shock pin.
    *Torque to 7 Nm
    
28. FRAME ASSEMBLY IS COMPLETE.
