The seatpost uses MCU suspension for ultra smooth and damped suspension action. Pre-load adjustment allows for a softer or harder ride. Fits bikes with a seatpost diameter of 33.9 mm. 580 mm length.

Includes:

  • BioLogic suspension seatpost
  • Saddle clamp

Saddle not included.

    I love riding my Tern Verge P9 but only on smooth roads. Now I’m able to take some bumps without much discomfort. IMO, this is a must upgrade! I only wish it have the measurement marks as with the stock seat-post.

    Hola, como estan, luego de haber usado por 6 meses el asiento biologic suspension seat post puedo da una opinion en español, la verdad que es util el sistema, mejora notablemente la comodidad, es una buena inversion ademas cuenta con una calidad muy buena y excelente terminacion. Se puede adaptar a cualquier tipo de asiento standard, la verdad que en ciudad es como andar en una nube y en tierra se comporta bastante bien el sistema de suspension. La unica critica que se le puede hacer es que podria venir con marcas en la tuerca de ajuste o indicaciones segun peso para que sea un poco mas didactico a la hora de ponerlo a punto en funcion del gusto del consumidor.

    Decent suspension. Worth it. Specially for tern bikes, as they do not have suspension.

    The seat post works well and you can adjust it. The bike weight will be higher but you can use the tires with higher pressure.

    Easy ordering process, fast efficient delivery , on time and as notified. Only glitch was the £25 bill for customs from Fedex that arrived a week later. Didn’t really expect that but I think others did highlight that in their reviews.
    Have 2 of these for Tern D8 mine and my wife’s bikes. Like others say no real instructions but a post is just a post. The saddle fixing is not quite so neat or in my mind so well engineered as the original that has an offset on the clamp. That said it may be a necessity of lining up the spring so the load is not pulling the moving post at an angle.
    Now had them a few months so have seen some use and would thoroughly recommend them. Certainly better than the stars post to ride.

    Fast delivery and received in good order. Fix my saddle on and try out for a ride on the pavement. Can feel the suspension/ bounce on bumpy pavement. Definitely give a much better ride than before. However, a manual / instruction should be given to allow us to fine-tunet the suspension better. But stll.. a good buy

    A year ago I’ve bought this seat post in black color(silver wasn’t available that time) but when
    started using it instead of my Dahon Vitesse D7 the original silver seat post I almost immediately felt much more comfort in perineum area for Moscow and country roads pavement I use to ride are far from being ideal and actually it does not matter any more whether it match my bicycle color or nor it match my sit bone which is much more important!

    This seatpost works perfectly with my Dahon Mariner D7. Instructions are very limited but, then again, it is a seatpost. I use it on my daily commuting in Washington DC and I can say it does make a difference. Sturdy, noiseless. Item was shipped quickly and properly packaged. Highly recommended.

    Speedy delivery and item received intact and in great condition.

    Fixed the seatpost to my ride and it works just as it should but like all who have given their reviews here, the item is definitely missing a manual. Looking around the web isn’t much help either. Finetuning the adjustment of the suspension is definitely vital because that’s primarily why people are buying this product but sadly due to the lack of information about it, you’ll not be able to fully max out it’s potential.

    Having sorted out the lack of instructions with you, and using the full range of adjustment, all is well.

    I replaced the original seatpost of my Tern link D8 and I’m very satisfied ,give me real more comfort on our paving stones in Belgium ,although I think riders weight must be more then 60kg ! Fast delivery and excellent service . I posted some pictures on the Tern forum .

    I purchased this seatpost to replace the original on my 20″ folding bike (Dahon Style), and the seatpost’s suspension make the rides more comfortable, but I am not sure that I understood how to adjust the stifness of the spring according to my weight, so I suggest Biologic to share a video on the web.
    Regarding the shipping was quickly enough, I am in Israel, but the Currier (FedEx ) charged me for more 25$ for what are called local services.
    Maybe Biologic could provide a less expensive shipping solution.

    Although it was interesting to have a air pump in the original seat post of my MuP24, the addition of a shock absorber makes for a much more confortable ride on our streets (cracks and bumps!) The shock absorber is very stiff which makes perfect sense for me weighing in at 200 lbs. Great by, Quick delivery (5 days). Thank you.

    I tried the suspension seatpost for my wife’s new Dahon. I returned it because it was not sensitive enough. She is not very heavy which seemed to cause the post to not work very well. I adjusted it as much as possible but not enough bounce. I would suggest this very someone who is at least 140lbs.

    I’m 6′ tall and could not adjust the stock seatpost on my folding bike to get enough seat-pedal distance. The Biologic Suspension Seatpost gave me the extra two inches I need for comfortable, efficient riding. The matte black finish matches the existing components perfectly. The ThinkBiologic team was extremely helpful.

    Three points:
    1. I bought this for length, not suspension, and am pleased to say that you can lock out the suspension feature.
    2. The seatpost is more than a pound (500gm) heavier than stock components!
    3. This seatpost is the same length as the factory part but has a smaller min insertion depth (perhaps because of its stronger and heavier materials). The reduced insertion may fatigue the frame of your bicycle – be aware of this.

    I have purchased Dahon MU P8 folding bike and use them for riding two-three times a week for an hour and a halve intensive riding (25-30 km). I have sufferd from back pains after riding due to faulty roads. I have purchased the suspension seat post and the change in the riding comfort is dramatic.
    in addition the service was great – 5 days shipping from Taiwan to my home addres in Israel.

    I purchased this seatpost to replace the original on my 2006 Helios since riding city streets on this bike can be sometimes jarring. The seatpost’s suspension helps. It’s adjustable, its motion is barely perceptible in use and it provides an increase in comfort. The post is heavier than my original post – and – required that I install a seat from another of my bikes since my original seat did not have the bars – only a (I suppose to be lightweight) plastic attachment.

    Quick delivery. Excellent product which provides what it promises. But I find two simple features are missing:
    -1 a scale on the post like on the pumppost two easily retrieve how deep the post was sunk after removing it for any reason.
    2-instructions about how to adjust the stifness of the spring to adjust it according to the weight of the biker. For example it should be given for what biker’s weight it is set at delivery & then for each turn of the adjusting scew by how many kg or lb this will modify the acceptable biker’s weight.
