WHAT IS SIXFINITY TECHNOLOGY AND HOW DOES IT WORK?
“Sixfinity is a 6-bar linkage suspension platform that allows kinematics and chassis structure to be
tuned for the specific demands, and packaging constraints of an E bike.
At its core, Sixfinity exhibits many underlying behaviors of Switch Infinity, but with intentional variations to
account for the fundamental dynamic differences that come with the addition of a drive unit and battery.
Like Switch Infinity, Sixfinity’s lower Switch link first moves upward, and then switches directions and
travels downward as the suspension moves from the extended to compressed states. As a result,
Sixfinity has a similar anti-squat profile proven with Switch Infinity. However, due to the drive unit assist,
the magnitude of the profile is reduced to bias the acceleration response towards increased traction.
The Sixfinity anti-rise profile is consistent across the entire travel range, similar to Switch Infinity.
However, the magnitude is reduced to bias the deceleration response towards increased traction for
a composed and predictable performance and chassis geometry while braking, even with the added
mass of a drive unit and battery.
Sixfinity’s leverage rate curve is linear and progressive. However, the progressivity is both increased
and adjustable to be tailored to one’s specific riding style, trail conditions or shock preference.”
DOES THE SIXFINITY SYSTEM REQUIRE MAINTENANCE?
The Sixfinity system utilizes a series of links that rotate on fully sealed bearings. The pivot interfaces
utilize floating collet and bearing assemblies designed for durability and minimizing friction. We
recommend checking the entire bike monthly for loose bolts, including the Sixfinity system. Bearing
service intervals can vary depending on climate, trail conditions and riding frequency. For more
information about this system and general bicycle maintenance, please consult the 160E user manual
or contact your nearest authorized Yeti Cycles dealer.
CAN I REPLACE OR MODIFY ANY YETI FRAME PARTS ON MY 160E?
All replacement frame parts for your 160E can be found through your local dealer or on our webstore.
Only genuine Yeti parts should be used when replacing any parts on your frame. We know there are a
lot of aftermarket products out there that seem legit but we do not have the ability to qualify and ensure
all of these products are safe to use on our frames. If it is found that any frame part has been modified
or replaced all warranties will be voided and all liability will be assumed by the customer.
CAN I CHANGE OR UPGRADE THE SPEC COMPONENTS ON MY 160E?
There are many options in aftermarket parts to upgrade or personalize your bike. Some parts are
standardized, especially from the big brands like Fox, Shimano, SRAM etc. You should always confirm
with a professional mechanic that your parts are the correct standard and correctly and securely mount
to your bike without any interference or play. Pay special attention to all the bike’s standards and check
the fit before use.
CAN I USE AN ANGLESET ON THE 160E?
The 160E 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 160E designed to use”
for more information.
WHAT TRAVEL FORK IS THE 160E DESIGNED TO USE?
The 160E is designed to run a 170mm 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 190mm fork no problem. Bottom
line - max axle to crown measurement of 607mm. 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 160E?
The short answer is the 160E can accept up to a 2.6” tire. There is great tire clearance on the 160E but
tire sizes vary widely by manufacturers, so it is hard to give a number that works for all brands.
CAN I FIT A WATER BOTTLE INSIDE THE FRONT TRIANGLE?
Yes, we designed the 160E to accommodate a standard sized water bottle inside the front triangle with
a piggy-back shock. We recommend using a side-entry cage for easiest access. The SM size is the one
exception and will fit Yeti’s 15oz Hot Lap water bottles.
WHAT CRANKS AND BOTTOM BRACKET CAN I USE ON THE 160E?
The 160E uses the EP801 drive unit which replaces the BB interface. The crank spindle is built into the
drive until and all you have to do is bolt on any Shimano EP8 compatible crank arm.
WHAT REAR WHEEL AXLE FITS ON MY 160E?
The 160E is designed to work exclusively with SRAM’s Universal Derailleur Hanger at 12x148mm
spacing. This axle had a thread pitch 12x1.0. Note that this axle is only compatible with frames
specifically designed with the Universal Derailleur Hanger.
WHAT TYPE OF HEADSET DOES THE 160E USE?
The 160E uses an Integrated 41mm/52mm tapered headset. This system allows for the headset
bearings to be contained inside the head tube for an overall lower ride height, more simplified
installation, and increased stiffness.
