    Caution;  Merge;  Workers Ahead! Yep Uptimizer Dropper Post Thread ~ Italian design & Swiss perfection




    There is no need to convince anyone about the benefits of the adjustable seatpost nowadays. Just a few years ago to have such an invention seemed rather whimsy. Today, the market is full of dropper posts both from the great big and renown companies [Rock Shox, Fox, X-Fusion, Specialized, Giant, Crank Brothers] as well as from smaller producers [Kind Shock, Thomson or non-existent Blacx]. However, there is also some room for very small entities such as German Vecnum or Swiss Yep Components.

    Yep Components is a small company that was created by the former Formula 1 driver - Adrea Chiesa who, among others, is now a commentator of Grand Prix for Swiss television. Andrea is also a cycling enthusiast, so he decided to contribute to the sport he loves in the a form of adjustable seatpost.




    Yep Components Uptimizer ST 155mm







    SPECIFICATION



    travel: 125mm / 155mm infinite travel
    system: hydraulic, air spring
    actuation: fixed external cable (ST) or internal cable routing (HC)
    material: aluminium 7075 -T6
    diameter: 30.9mm i 31.6mm
    • length: 375mm / 405mm / 435mm
    weight: 500 / 570g
    head: symmetrical zero offset, 2 bolts clamp design
    MSRP: €360


    Yep currently offers two models: Uptimizer ST [external cable routing with actuation mechanism fixed at the collar] and Uptimizer HC [internal or so-called stealth cable routing]. Seatposts, just like most of the offerings today, have pneumo-hydraulic system that allows you to set the height of the saddle anywhere within two offered travels [125mm and 155mm]. Seatposts and are controlled through the joystick-style remote, similar to that offered in the old Crank Brothers Joplin or currently in the X-Fusion Hilo. Both dropper posts from Yep Components are available in two diameters: 30.9mm and 31.6mm; as well as two different lengths: 375mm [125mm version] and 435mm [155mm version].




    Uptimizer ST






    Uptimizer HC







    MANUALS








    SEATPOST




    The Uptimizer post has been designed to operate at lower pressure [130/180 PSI] in comparison with other products on the market that are pumped up to 250 PSI. Lower pressure is better for the seals and prolongs the life of the system. Seals come from Swiss producer Angst & Pfister; grease and oil is supplied by Swiss company Motorex and from German specialist in the field of low friction come the maintenance-free IGUS iglidur® bushings.

    The seatpost execution is just stunning! Ttere is CNC machining everywhere with a lot of attention to details – quality at its best. Under the sealed aluminum CNC-carved lid adorned with the flag of Switzerland and cleverly mounted using the O-ring you can find the actuation system. At the end of the regular shifter cable there is a bolt-on steel cable stop which can be quickly installed or removed from the hook acting as the lock lever. Such an arrangement allows for the very quick way to disconnect the cable and lets you remove the seatpost from the frame for the service, transport of bicycle or alien attack... The aforementioned lever/hook is connected through a steel cable to a activator rocker at the bottom of the seatpost which directly acts on the hydraulic valve locking the seat at desired height. In the stealth version with internal cable routing [Uptimizer HC] the cable is attached directly to this activator rocker, eliminating additional moving parts.




    A quick way of disconnecting the cable from the seatpost



    The mechanism that opens/closes the hydraulic valve at the bottom of the post


    The lower tube is hard anodized in a distinctive golden color [Renthal bars come to mind]. An additional advantage is the rough surface [result of the shot peening process] which improves friction eliminating the risk of the seatpost rotation in the frame and allowing to reduce clamping force.


    The top tube is anodized black and you will not find any roughness here. The saddle is mounted in a two-bolt clamp allowing for precise seat angle adjustment. In addition, symmetrical design of the clamp [without any offset] means that you can rotate the seatpost 180 degrees and install it in the frame the way you prefer [with the cable in front or back].





    Symmetrical clamp lets you rotate the post 180°


    Under the upper part of the clamp there is a sealed screw/cap and underneath you will find the air valve. After screwing in the red adapter [included] we can adjust the air pressure with a regular shock pump. Adding more pressure makes the seat going up faster. Interestingly enough, higher pressure also reduces the problem of pulling out the seatpost when lifting the bike by the saddle. Do not pump too much air though because then you have to put a lot of effort to lower the seat. I decided to conduct some experiment and measure how the pressure increases when the seat travels down. The seatpost with 155mm of travel has the output pressure of 130 PSI [in the upper position] which rises to 200 PSI [in the lowest position]. Please, take into consideration this 70 PSI increase when setting the air pressure.




    In the clamp you will find the cap...



    ...underneath there is an air valve...



    ...after screwing in the red adapter we can adjust the air pressure.



    Nominal air pressure at extended position: 130 PSI



    Air pressure at the lowest position: 200 PSI








    REMOTE




    The remote was designed to be operated with the index finger...



    ...or with the thumb.


    Yep seatposts are operated through the joystick-style remote. Theoretically, this allows to install the remote anywhere, at any angle. Mounting clamp of the remote has an open design so it can be pressed in and tightened with a screw without removing the grips, shifters, etc. In bikes without a front derailleur and shifters there should be no problem with the installation of the joystick on the left side of the handlebar. The intention of the designers was to operate the remote with your index finger [pictured above]. Andrea says that it allows you to grip the handlebar better since the thumb does not wander in search of the remote, especially if it is mounted above the bar. Of course, the remote can be also operated with the thumb which illustrates the picture above.

    In my opinion shifter has one major drawback: its specific design limits the compatibility with some shifters and brake levers. If you still use front and rear the derailleur and have shifters on both sides of the bar or, God forbid, have an additional suspension remote, the optimal and ergonomic installation of all controls becomes problematic or even impossible. I know Yep is working on a new, more compact remote that should solve this problem.




    The remote can be mounted this way...



    ...or this way...



    ... but other remotes work well too :-)







    OPERATION


    Seatpost has no noticeable play neither lateral or vertical. You need relatively small movement of the remote to lower or raise the saddle and stop at any height within 125mm or 155mm of travel. Like in other hydraulic systems we can control the speed of seatpost by how far we push the remote. However, even if you press the remote as far as it goes your family jewels are safe because the movement of the seatpost is damped and saddle gently reaches its highest position.

    On every bike forum you will find the question: Which seatpost is the best? The answer is simple: the reliable one! In my opinion this is the most important advantage of the adjustable seatpost. Unfortunately, it is impossible to talk about reliability after a few rides and only months of use and abuse will tell if the seatpost will continue to work with the precision of a Swiss watch.

    Long Term Review

    I have been riding the Uptimizer ST seatpost for almost half a year and it works like the first day I got it! I have not encountered any [!] difficulties during this time. Maybe 6 months may seem like a short period but when I think about my Kind Shock seatposts that failed after a few days and weeks, the six-month of trouble-free use seems to be a big success taking into consideration the failure rate of the seatpost from other manufacturers, even Thomson did not avoid the initial mishaps.

    Seatpost has not developed any more play from that present on day one. I have not experienced any problems with the so-called "seatpost pump" that I did with my previous Kind Shock posts.

    When servicing the seatpost I noticed that the collar [secured by threadlocker] is not only performing the role of dust seal. There is a 10mm high IGUS iglidur® bushing pressed in the collar that further stiffens the construction [this explains the use of threadlocker]. After removing the collar the seatpost slides almost without any friction, it seems that the only noticeable friction occurs on the wiper seal in the collar.





    In conclusion, this is definitely the best seatpost I have ever ridden and I tried many of them: Kind Shock [all models], Rock Shox Reverb, Fox DOSS, Blacx Jewel, X Fusion Hilo, Crank Brothers Joplin, Gravity Dropper. I think that

    Yep Uptimizer is the Holy Grail of dropper posts!

    This opinion comes from a man who is very fussy and meticulous about the quality and durability.

    For my new bike I chose Uptimizer HC i.e. "stealth" version with internal cable routing so the time will show how this one performs. So far so good.

    Caution;  Merge;  Workers Ahead! Buying cheap is expensive

    The retail price is €345, or close to $435 at today’s exchange rates. Being more than a RockShox Reverb Stealth, but less than a Thomson Elite Covert Dropper, it is decently priced for a high-end dropper seatpost, especially when you consider the features and construction.

    The price is relative to the buyer's standard of value. I'd rather pay more for more reliable product. Buying cheap is expensive.

    Probably better materials than the LEV and I do like how it has a steel cable instead of the kevlar that KS uses internally... So maybe worth it design and idea looks to practically the same.

    I'd like to hear some reviews from people that have ridden them hard in crappy conditions for more than 6 months AAANNND who have had problems with them requiring self service.

    All new dropper posts are supposed to be worry free. All dropper posts eventually need to be worked on. At the end of the day, the real questions are, how often does it need service and how hard is it to do? The next questions would be, how hard are parts to get and how reliable is customer service?

    Can you post some pictures? 😉

    It looks good but I think the remote is too big and servicing here in Canada may be a problem. I am hopeful an ultra reliable, light, and inexpensive post will become a reality.
    I got some bad ideas in my head.

    I pulled the trigger on the uptimizer should be here next week probably not the smartest move on my part since I'm state side and no one has even heard of this an uptimizer on this side of the pond but I'll be the guinea pig. hell maybe I'll start distributing them over here.

    So it's like my command post, except you have to take the seat off to adjust the pressure and you need and adapter.

    Genius!

    I'm anxious to hear more reports from real world use of this post.

    Rockshox - Time tested as reliable as long as you like regular rebuilds. Great customer service and support with home mechanic work.
    Kindshock - Time tested as reliable and buttery smooth.........if you follow this thread:KS LEV - DIY Cartridge Rebuild and can stomach a now notoriously poor customer service model.
    Special Ed - Works. Feels Cheap. Is cheap. Reliability = YMMV.
    Gravity Dropper - Works. Feels Cheap. Is expensive. The only truly reliable post available in the US.
    Thomson - Wow, that's expensive for a Command Post with a better seat clamp.
    Fox Doss - See Thomson. Reliability untested.

    Good summary of the dropper post market right there... I've had 6 warranty returns in the past year split among a KS Lev, X-Fusion Hilo SLS, and Rockshox Reverb Stealth. Have sold them all as a result. I am personally now in wait mode until the new 9point8 Fall Line dropper hits the market next spring. Canadian made and reasonably priced. What's not to like.

    Nice link to a little known newcomer. Fingers crossed on that one.

    Ha ha, I'd forgotten about the HiLo. Can't believe anyone still uses those. Have never heard a single good experience from anyone using them. Too bad, they're nice people at XFusion.
