A clean, strong replacement rear axle for compatible Yeti mountain bikes.
The Burgtec Yeti 171mm Rear Axle is made for compatible Yeti frames using a 12×148mm Boost rear hub and an axle with an M12 × 1.5mm thread.
Machined from 7075 aluminium, it replaces the original axle with a tidy leverless design. A 6mm hex fitting is used for installation and removal, while a replacement dropout bolt is also included.
Check Compatibility Before Ordering
This axle is designed specifically for compatible Yeti frames. A 12×148mm Boost rear hub does not confirm compatibility by itself. The axle length, diameter and thread pitch must also match the frame.
Burgtec lists compatibility with the following Yeti models:
- Yeti SB165
- Yeti SB150
- Yeti SB140
- Yeti SB130
- Yeti SB115
- Yeti SB100
- Yeti SB4.5
- Yeti SB5
- Yeti SB5.5
- Yeti SB6
Specifications can vary between frame generations. Compare the original axle or confirm your frame year and axle measurements before ordering.
7075 Aluminium Construction
The axle is machined from 7075 aluminium for a useful balance of strength, stiffness and low weight. It is manufactured to the required Yeti dimensions rather than being a universal replacement axle.
Clean Leverless Design
The leverless profile provides good clearance around the rear dropout and gives the bike a clean finish. Installation and removal are handled with a 6mm hex key, so there is no external lever to reposition or catch on trail debris.
Use a good-quality hex tool and follow Yeti’s tightening instructions. Check that the threads are clean and start the axle by hand to reduce the risk of cross-threading.
Key Features
- Strong, lightweight 7075 aluminium construction
- Clean leverless profile provides good dropout clearance
- Installs and removes using a standard 6mm hex key
- Replacement dropout bolt included
- Available in a range of Burgtec colours
Our Thoughts
This is a straightforward replacement or colour upgrade for the Yeti frames it is designed to fit. The leverless profile looks tidy and provides good clearance around the rear of the bike, while the included dropout bolt gives you the matching hardware needed for installation.
The important part is confirming all three axle measurements. Do not order it based only on your bike having a Boost rear hub. The required specification is 171mm long, 12mm in diameter and M12 × 1.5mm threaded.
