ARC frame and part compatibility
What size seat post and seat collar does the ARC use?
The ARC uses a 31.6mm seat post and a 36.4mm seat collar. Seat collar torque depends on the seat post manufacturer's recommendation.
Can I run an internally routed (stealth) dropper post on the ARC?
Yes. The ARC has routing for stealth (internally routed) dropper posts only.
What is the longest travel dropper post I can run on the ARC?
The longest ARC dropper post depends mostly on your inseam. The ARC has an uninterrupted seat tube and no frame limit on dropper length, so you can run any travel as long as the post is above its minimum insertion mark and your tire does not rub your saddle. Your local Yeti dealer can help you choose. Yeti runs a 175mm drop on all ARC frame sizes.
What travel fork is the ARC designed to use?
Model year 2026 and newer ARCs are designed for a 130mm to 140mm travel fork. Model years 2022 to 2025 are designed for a 130mm fork. The ARC frame is tested to a maximum axle-to-crown of 564mm, so you can run up to a 150mm 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.
Can I use an angleset on the ARC?
No. The ARC has an integrated headset with the headset cups molded into the frame. Some aftermarket anglesets fit this headset style, but the ARC 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 ARC?
The ARC works only with SRAM's Universal Derailleur Hanger (UDH) axle at 12 x 148mm spacing, with a 12 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 ARC?
The ARC 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. The ARC is a 1x-only frame.
What chainline was the ARC designed around?
The ARC was designed around a 55mm chainline. Other chainlines may work depending on the crank and chainring, but check clearance first. The minimum clearance from the chainring teeth to the chainstay is 3.5mm.
What is the largest chainring that fits on the ARC?
With Shimano or SRAM 55mm chainline Boost cranks, the ARC fits up to a 34T round or 32T oval chainring. The minimum is 28T round or 30T oval. The limit depends on crank chainline and chainring shape. Not sure? Ask your local Yeti dealer or contact Yeti Cycles support.
Does the ARC have ISCG mounts?
Yes. The ARC has an integrated 2-bolt ISCG '05 mount. The ARC 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. A 3-bolt ISCG '05 guide with a bash guard is not recommended and voids the frame warranty.
How big a rear rotor fits on the ARC?
The ARC runs a 160mm rear rotor without a brake adaptor. With a brake adaptor, the ARC fits up to a 180mm rear rotor.
How big a tire can I fit on the ARC?
The ARC 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 on the ARC?
Yes. The ARC fits a standard water bottle inside the front triangle and a second bottle under the down tube. A side-entry cage gives the easiest access.
Can I convert the ARC to a mullet (27.5" rear wheel)?
It is possible, but Yeti does not recommend it. A 27.5" rear wheel on the ARC 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.
ARC parts, upgrades, and warranty
Can I upgrade the components on my ARC?
Yes. Many aftermarket parts fit the ARC, and parts from major brands like Fox, Shimano, and SRAM are largely standardized. Have a professional mechanic confirm each part matches the ARC's standards and mounts securely without interference or play. Check the fit before riding.
Can I replace or modify Yeti frame parts on my ARC?
Use only genuine Yeti replacement frame parts on the ARC. 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 ARC 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 ARC?
The ARC 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.
