Can I use an angleset on the SB165 27.5?
The SB165 was designed with an integrated headset which has the headset cups molded into the frame so you can easily drop the bearings into the cups. There are some aftermarket angle-sets available for this style headset however the frame was not tested for the use of these and therefore should not be used. Yeti's warranty will be voided if it is found an angleset was installed on the frame and all liability will be assumed by the customer. See “What travel fork is the SB165 designed to use” for more information.
What travel fork is the SB165 27.5 designed to use?
The SB165 is designed to run a 180mm travel fork. We tested this frame to 20mm over the spec fork. So if you’re feeling the need to beef up the fork you can run up to a 200mm fork no problem. Bottom line - max axle to crown measurement of 599mm. Increasing your fork travel will slacken the head angle and seat tube angle and raise the bottom bracket. Running a shorter fork is fine too if that suits you. Shortening the fork will steepen the head angle and seat tube angle and lower the bottom bracket For more geometry information, check out the geometry section.
How big of a tire can I fit on the SB165 27.5?
