LT adjustments
Why would I adjust the leverage rate on the LT?
The LT has a leverage rate flip chip on the lower shock mount, so you can tune the suspension feel to your riding style and terrain. The stock setting is 20%, which is the best place to start. Experiment to find what works for you. The Yeti shock setup page has more about leverage rates, and the LT owner's manual explains how to change the chip.
What chainstay length dropouts should I use on my LT?
Every LT frame comes with two sets of dropouts: standard (+0mm) and long (+10mm). Choose based on your preference, riding style, and terrain, and experiment to see what works best. You may need a different chain length when you switch dropouts; check your drivetrain manufacturer's manual.
Can I run the LT as a mullet (27.5" rear wheel)?
Yes. The LT has a flip chip at the seat stay and rocker connection for a 29" or 27.5" rear wheel, and the geometry stays the same in both positions. Yeti also makes a mullet slack chip set that slackens the head angle by 0.5 degrees and lowers the bottom bracket by 6mm for rowdier terrain. The LT owner's manual has the setup steps.
Can I use an angle-adjust or reach-adjust headset on the LT?
Yes. The LT uses a ZS44/ZS56 zero stack headset and fits aftermarket angle-adjust headsets up to +1 or -1 degree and reach-adjust headsets up to +5 or -5mm. Adjustable headsets are not included with LT bikes or framesets. Any adjustment beyond these limits is not approved and voids the warranty.
LT frame and part compatibility
What size seat post and seat collar does the LT use?
The LT uses a 31.6mm seat post and a 36.4mm seat collar.
What is the longest travel dropper post I can run on the LT?
The longest LT dropper post depends mostly on your inseam. The LT has an uninterrupted seat tube, so 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. The LT owner's manual lists maximum insertion depth and minimum saddle height by size, and your local Yeti dealer can help you choose.
What travel fork is the LT designed to use?
The LT is designed for a 170mm travel fork. Yeti tested the LT frame to 20mm over the spec fork, so you can run up to a 190mm fork. The maximum axle-to-crown measurement is 608.7mm.
- 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.
Can I run a dual crown fork on the LT?
Yes. The LT works with a dual crown fork up to 190mm of travel and a maximum axle-to-crown of 608.7mm.
What headset and top cap does the LT use?
The LT uses a ZS44/ZS56 tapered headset. The LT is tested to stricter standards that need a thicker head tube, so it uses a custom 53.5mm top cap.
What rear wheel axle fits on my LT?
The LT works only with SRAM's Universal Derailleur Hanger (UDH) axle at 12 x 148mm spacing. The axle is 172mm long with an M12 x 1.0 thread pitch. This axle only fits frames designed for the Universal Derailleur Hanger.
What cranks and bottom bracket can I use on the LT?
The LT uses a BSA 73mm threaded bottom bracket and is compatible only with wide q-factor cranks. Shimano, SRAM, and RaceFace cranks fit; other brands need a fit check.
What chainline and chainring size fit the LT?
The LT was designed around a 55mm Boost chainline and fits chainrings from 28T to 34T round.
Does the LT have ISCG mounts?
Yes. The LT has integrated ISCG '05 mounts. The LT 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 LT?
The LT runs a 200mm rear rotor without a brake adaptor. With a brake adaptor, the LT fits up to a 220mm rear rotor.
How big a tire can I fit on the LT?
The LT fits tires up to 2.6" wide. Actual tire sizes vary by manufacturer, so clearance can differ between brands.
Can I fit a water bottle inside the LT front triangle?
Yes. The LT fits a standard water bottle inside the front triangle with a piggyback shock. A side-entry cage gives the easiest access.
Does the LT have in-frame storage?
Yes. The LT has an integrated storage compartment with a latching door, with room for tools, flat repair gear, snacks, gloves, and light layers. The LT owner's manual explains how to adjust the door latch.
Does the LT accommodate a tracking device?
Yes. The LT has a holder in the lower down tube access port for an Apple AirTag or Tile Sticker (2020 or 2022 model). The LT owner's manual has installation steps.
Is there a frame protection kit for the LT?
No. Yeti does not offer a frame protection kit for the LT. Yeti recommends RideWrap frame protection for the LT.
LT suspension setup
What shock does the LT use?
The LT uses a 205 x 65mm trunnion-mount rear shock. Some shocks can be locked out, but Yeti recommends running the LT shock fully open for the best compliance and traction.
What shock hardware does the LT use?
The LT uses a standard trunnion mount at the top and M8 x 40mm hardware at the bottom. The lower mount holds the adjustable leverage rate chip.
Can I put a coil shock on the LT?
Yes. The LT works with both air and coil shocks. With a coil shock, Yeti suggests a higher leverage rate chip setting, because coil shocks usually work best at higher leverage rates.
What sag should I run on the LT?
Start the LT at 30% sag, which is 19.5mm 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.
What is Sixfinity and does it need maintenance?
Sixfinity is the LT's patented 6-bar suspension platform; the Yeti Sixfinity page explains how it works. Sixfinity uses links that rotate on fully sealed bearings, with floating collet and bearing assemblies at the pivots. Check the whole bike monthly for loose bolts, including the Sixfinity links. Bearing service intervals depend on climate, trail conditions, and how often you ride. Your local Yeti dealer can service the bearings.
LT parts, upgrades, and warranty
Can I upgrade the components on my LT?
Yes. Many aftermarket parts fit the LT, and parts from major brands like Fox, Shimano, and SRAM are largely standardized. Have a professional mechanic confirm each part matches the LT's standards and mounts securely without interference or play. Check the fit before riding.
Can I replace or modify Yeti frame parts on my LT?
Use only genuine Yeti replacement frame parts on the LT. 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 LT 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 LT?
The LT frame has 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. The warranty does not cover ordinary wear and tear, neglect, or intentional damage. See the Yeti Cycles Warranty for full terms.
