SB130 frame and part compatibility
What is the difference between the SB130 and the SB130 LR?
The SB130 LR (Lunch Ride) uses the same frame with a longer-stroke 210 x 55mm shock, giving 137mm of rear travel instead of 130mm. The SB130 LR is built around a 160mm fork; the SB130 is built around a 150mm fork. Frame standards and part fit are otherwise the same.
What size seat post and seat collar does the SB130 use?
The SB130 uses a 31.6mm seat post and a 36.4mm seat collar.
Can I run an internally routed (stealth) dropper post on the SB130?
Yes. The SB130 has routing for stealth (internally routed) dropper posts only.
What is the longest travel dropper post I can run on the SB130?
The longest SB130 dropper post depends mostly on your inseam. You can run any travel as long as the post is above its minimum insertion mark, your tire does not rub your saddle, and the dropper does not bottom out in the frame. Your local Yeti dealer can help you choose. Yeti runs a 125mm drop on SM frames, 150mm on MD frames, and 175mm on LG and XL frames.
What travel fork is the SB130 designed to use?
The SB130 is designed for a 150mm travel fork, and the SB130 LR for a 160mm fork. Yeti tests its frames to 20mm over the spec fork, so you can run up to a 170mm fork.
- A longer fork slackens the head tube and seat tube angles and raises the bottom bracket.
- A shorter fork steepens the head tube and seat tube angles and lowers the bottom bracket.
What headset does the SB130 use?
The SB130 uses an integrated 41mm/52mm tapered headset, with the bearings inside the head tube for a lower ride height, simpler installation, and more stiffness.
Can I use an angleset on the SB130?
No. The SB130 has an integrated headset with the headset cups molded into the frame. Some aftermarket anglesets fit this headset style, but the frame was not tested with them and they should not be used. Installing an angleset voids the Yeti warranty, and the customer assumes all liability.
What rear wheel axle fits on my SB130?
The SB130 works only with a Yeti or Shimano 148 x 12mm E-Thru rear axle. The rear triangle is optimized for stiffness and weight with these specific axles.
What cranks and bottom bracket can I use on the SB130?
The SB130 uses a PF92 (92mm press fit) bottom bracket and is compatible only with wide q-factor cranks. Shimano, SRAM, and RaceFace cranks fit; other brands need a fit check.
How many bottom bracket spacers do I need on the SB130?
The SB130 has a 52mm chainline. With a SRAM DUB PF92 bottom bracket and a SRAM DUB 52mm chainline crankset, use a 2mm clip-on spacer on the drive side and no spacer on the non-drive side. With a Shimano PF92 bottom bracket and a Shimano 52mm chainline crank, no spacers are needed.
What chainline was the SB130 designed around?
The SB130 was designed around a 52mm Boost chainline. Other chainlines may work depending on the crank and chainring, but check clearance first.
What is the largest chainring that fits on the SB130?
With Shimano or SRAM Boost cranks, the SB130 fits up to a 34T round or 32T oval chainring. With RaceFace 52mm chainline cranks, it fits up to a 32T round or 32T oval. The minimum is 28T round or 30T oval. Not sure? Ask your local Yeti dealer or contact Yeti Cycles support.
Does the SB130 have ISCG mounts?
Yes. The SB130 has integrated ISCG '05 mounts. It works best with low-profile modern chain guides; some older guides with larger upper guides may not fit. Always fit-check a specific chain guide before riding.
How big a rear rotor fits on the SB130?
The SB130 runs a 180mm rear rotor without a brake adaptor. With a brake adaptor, it fits up to a 203mm rear rotor.
How big a tire can I fit on the SB130?
The SB130 fits tires up to 2.5" wide. Actual tire sizes vary by manufacturer, so clearance can differ between brands.
Can I fit a water bottle inside the SB130 front triangle?
Yes. The SB130 fits a standard water bottle inside the front triangle, even with a piggyback shock. A side-entry cage gives the easiest access.
Can I convert the SB130 to a mullet (27.5" rear wheel)?
It is possible, but Yeti does not recommend it. A 27.5" rear wheel on the SB130 lowers the bottom bracket too much and slackens the head tube and seat tube angles. If those changes suit your riding style, it is your call.
Why are there frame guards on the SB130?
The SB130 has custom seat stay, chainstay, and down tube guards to protect the frame from rocks and roots and to keep chain slap quiet.
What is the difference between the TURQ and Carbon series SB130?
TURQ series SB130 frames use Yeti's highest-grade carbon fiber for the best balance of stiffness, durability, and compliance. Carbon series frames use a modified layup with different materials to lower the price while keeping the strength and stiffness of the TURQ frame. A Carbon series SB130 frame weighs about 220g more.
SB130 suspension setup
What shock does the SB130 use?
The SB130 uses a 210 x 52.5mm rear shock. The SB130 LR uses a 210 x 55mm rear shock. Some shocks can be locked out, but Yeti recommends running the shock fully open for the best compliance and traction.
What shock hardware does the SB130 use?
The SB130 uses M8 x 36mm hardware on the air can side and a custom Yeti reducer on the shaft side. If you swap shocks, you can buy the Yeti shock eyelet spacer on yeticycles.com.
Can I put a coil shock on the SB130?
Yes. The SB130 works with both air and coil shocks.
What sag should I run on the SB130?
Start the SB130 at 30% sag, which is roughly 16mm of shock stroke, for the best pedaling efficiency and terrain compliance. Set sag at your normal riding weight with your gear on. You can go slightly above or below 30% to suit your preference. The Yeti shock setup calculator gives starting settings for your shock.
How often should I service the SB130 Switch Infinity link?
Grease the SB130 Switch Infinity link every 40 hours of riding through its external grease ports. Do not over-grease it, and wipe off dust and dirt regularly. Grease and service parts are available from the Yeti webstore or your local Yeti dealer.
SB130 parts, upgrades, and warranty
Can I upgrade the components on my SB130?
Yes. Many aftermarket parts fit the SB130, and parts from major brands like Fox, Shimano, and SRAM are largely standardized. Have a professional mechanic confirm each part matches the SB130's standards and mounts securely without interference or play. Check the fit before riding.
Can I replace or modify Yeti frame parts on my SB130?
Use only genuine Yeti replacement frame parts on the SB130. You can get them from your local Yeti dealer or the Yeti webstore. Yeti cannot verify that aftermarket frame parts are safe on its frames. If any frame part is modified or replaced with a non-Yeti part, all warranties are void and the customer assumes all liability.
What is the warranty on the SB130?
The SB130 frame and Switch Infinity link have a lifetime manufacturer's warranty against defects for the original purchaser from an authorized Yeti Cycles dealer. Paint and finish are covered for 1 year. Yeti will repair or replace, at its discretion, any frame it finds defective. To use the warranty, register your bike online at yeticycles.com and take it to an authorized Yeti Cycles dealer for processing.
