Just In – Yep Components Uptimizer Dropper Seatpost

by Brian Mullin on March 4, 2014

If you spend anytime riding in difficult terrain, a dropper post is one of the handiest and most advantageous products to add to your bike.You can drop the post for descending, offering better
control and balance with a lower center of gravity, and extend it for
climbing and normal riding to get proper leg extension for pedaling.

Yep
Components has joined the crowded ranks of dropper seatposts with their
new Uptimizer. The Swiss company is run by former Formula One driver
Andrea Chiesa, who also happens to be an avid mountain biker. The
aircraft-grade 7075-T6 aluminum Uptomizer is cable-actuated and comes in
two versions—the externally-routed ST and the internally-routed HC,
with travel lengths of 125mm and 155mm, and in 30.9mm and 31.6mm
diameters. The hydraulic, air-sprung post features Angst & Pfister
seals and dust rings, Motorex grease and oil, and IGUS iglidur bushings.
The 500-gram post utilizes a zero-offset saddle two-bolt clamp, and a
joystick-style remote lever.

Yep
designed their seatpost to run with a lower air pressure (130 to 180
psi) compared to the industry norm of 250 psi, which helps reduce stress
on the seals and increase longevity, according to the company. Using a
specific internal design and precision build, they focused on
hydrodynamic problems, valve shape and oil conducts to avoid vortices
and cavitations, all of which provides silent and sensitive progressive
action. The synergy of their entire design means it only requires a very
light touch on the joystick remote to activate the system.

The
externally cable actuated ST version (shown above) connection is
located in a small compartment on the collar, much like the KS Lev
system, so it’s stationary relative to the saddle’s up and down
movement, avoiding interference issues with legs, tires, and linkages.
The internally cable actuated HC version connects directly to the bottom
of the post, much like the KS Lev Integra, creating a stealth or
internal cable routing system.

Installation

The
ST version which I tested, can have the actuator collar-box located in
either a front or backward facing position, depending on personal
preference. Once the positioning is decided, you take off the
industrial-strength rubber band on the collar-box, take off the cover,
and pop the cable end piece into the actuator lever, and reverse the
process for completion. You then cut the housing and cable to the
required lengths, snap the remote onto the handlebar, build the joystick
remote lever, thread the cable and housing though the joystick, and
clamp everything down to specs. It was a pretty simple and fast process
to install everything, and I only had to adjust the cable once after
things settled in.

First Impressions

The
Uptimizer remote utilizes a one-piece open-ended clamp, that pops onto
the handlebars and clamps down with a single bolt. It can be placed just
about anywhere on the bars, making it very customizable for
positioning, and the joy stick can actuate the seatpost by being pulled
or pushed. I placed the remote on the outside of the left hand brake,
and had it tilted downwards underneath the brake lever, so I had easy
access for actuation while riding. I enjoyed the smooth feel of the
joystick’s actuation back into the collar-box and the 360 degree of
movement of the lever and the light touch that is required. I liked that
it was a mechanical connection and actuation system, since I think, it
makes it more reliable, quicker and has fewer issues with temperature
changes.

The seatpost moved with a silky smoothness, that felt
fluid and responsive, with barely any stichion. The infinite travel
worked perfectly, and I could place the saddle where I wanted with a
slight body weighting on the saddle. I didn’t check the air pressure in
the post, but the speed was more than adequate for returning upwards.
The response time to any position I wanted was fine, and I never felt
like it was slow. It’s still pretty new, but it seemed there was very
little to no lateral play from the post, making for a rock-solid
platform. I really liked the 155mm travel version that I tested, and I
appreciated the extra room it gave me to get the saddle as low as
possible.

Final Thoughts

The
Yep Components Uptimizer dropper seatpost is a high quality Swiss made
product, and the design, materials and build are top notch. The
smoothness and fluidity of the movement are excellent, and the
mechanical connection is reliable and quick, and the trick joystick
remote with its 360 degree of actuation is superb, allowing either
pushing or pulling lever action. The cable directly attaches to the
post’s collar or the bottom for a stealth mode, instead of the atypical
position on top of the telescoping head, making for a much more pleasant
interface. At around $500, it’s definitely a pricey seatpost, but the
Uptimizer is a handmade product from Switzerland made with incredible
craftsmanship.

The hand-built posts are only available directly
through Yep currently, and they don’t have a US distributor as yet. At
this point, their e-shop is only set up for Swiss customers, so others
will need to contact them
through their website to get an order processed. The seatpost has a
two-year warranty, and for any repair work, you’d need to return it to
their workshop located in Switzerland.

Yep Components is a small
startup company, and 2014 is their first year in the marketplace. I see a
great future for this company, and with continued design work and
upgraded tooling and increased throughput, they’ll have better pricing
and an improved product. Hopefully, as sales and production increases,
they’ll get a US distributor and service center.
