ROADNADO Bike Carbon SeatPost MTB Seat Post Carbon Fiber Seatpost Adjustable Offset Ultralight Bicycle Seat Tube for Road Bike Mountain Bike BMX Matte Black

It seems like a solid seat post but I have an issue with adjusting the angle of the seat itself.after installing the post if you want to adjust the seat angle you basically have take the seat off adjust the rear screw then tighten the front one..it's a pain in the ass .

Preliminary review: have not ridden on this but wanted to give some initial impressions: weight, measured on a digital scale: 174 grams.Nice finish and graphics.Special Note: Several reviewers have mentioned that you need a saddle with a hole or a split so you can have access to one of the adjusting bolts. Although helpful and convenient to have access to the front hex from above, as long as you can adjust the bolt from the side of the saddle with your fingers, you do not need to have access to the top with a tool.You treat the front bolt as sort of a fixed bolt. Then you tighten the rear bolt with a 5 mm hex tool. After the rear bolt is tightened, you evaluate the tilt. If the resulting tilt is not to your liking, you simply loosen the rear bolt enough so you can make an adjustment to the tilt by screwing the front bolt in or out with your finger - screwing it in will tilt the saddle down, increasing it will allow the saddle to tilt up. You won't be able to judge the tilt until the rear bolt is completely tightened again. If it's still not right, you make another adjustment.It might take a couple of adjustments but it can be accomplished in a few minutes of fiddling.UPDATE: I purchased this seatpost for the stoker position on a tandem. It replaced an expensive, top of the line shock absorbing seatpost from Cane Creek. No problem with that seatpost, but in our case, stoker reported that it encouraged her to 'bounce, at higher cadences since she is not a very smooth peddler.Stoker reports that this seatpost is comfortable enough, absorbing some road 'buzz,' though of course not taking the big hits out. Still, it has helped to minimize her bouncing. So far, this seatpost has proved to be durable. Stoker is 140lbs, so no featherweight. I used some carbon fiber assembly paste to help hold it in place. In case you're interested, or if this is important to you; I wouldn't say the graphics are easily removed.Happy with this purchase and will likely get another for other bikes as the need arises.NOTE: Though I am using this in the stoker position of a tandem, I am not recommending it for the captain position. The additional torque placed on a seatpost in the captain position by the stokers handlebars will introduce some additional stresses to a seatpost which could cause long term problems in a carbon seatpost.

This uses a bolt from below and above to attach the seat. I had to cut out some of the plastic you see though the "hole" in the seat so I could get to the bolt from above. To adjust the angle, you have to loosen one bolt and tighten the other - a bit tedious. Fortunately you don't have to do that very often. Quality of the carbon post seems very good, I have ridden maybe 200 miles on it, and have taken it off and put it back on a few times and it's super solid.

Hard to beat the $22 I paid for this post. That, in combination with the solid, stiff build on the carbon tube makes it worth it. I ended up cutting down the length just a bit to save even more grams, which is easily done (just be careful). The only thing I don't like about it is the clamp on the post.First ride I thought it was clamped tight, but on a stiff hit in a rocky section of trail, the clamp settled further, making a disconcertingly loud click that sounded like a 'crack'. Also the angle of my seat changed, so I had to adjust on trail. Problem is, once the clamp is actually settled into the carbon cradle, it's not moving. So you have to give it some juice to loosen it so you can then re-adjust the front screw and then tighten down the rear (I don't have a seat with a hole, so the front has to be loose so I can turn the front screw by hand. Then you just tighten up the rear. If you have a hole in the seat, this clamp would be MUCH easier to adjust and probably wouldn't be an issue at all.I ended up having to adjust it a couple of times while on trail, but once it was dialed, it wasn't going anywhere.Overall though, for the price and despite the finicky clamp, this post is a solid buy.

The original seat post on my son's Specialized mountain bike was a two piece aluminum configuration where the tube was affixed to the seat mount. Over time the connection between the mount and post became loose so the seat wouldn't stay straight. My teen son is as conscious of style as I am of value. He liked the look of it and I liked that it was a one piece design and reasonably priced. It arrived quick and the quality is great. It is solid and light. I shortened it's length a few millimeters using a table mounted disk sander so that it wouldn't hit the rear suspension shock and I can see that fiber strands; which is a good thing. This is unquestionably carbon fiber and it is well made. Mounting the seat was a little bit difficult because only one of the two mounting bolts is accessible when the seat is mounted, but it just took a little extra fidgeting. If the need arouse, I would not hesitate to purchase this item again.

For a cheap price, a full-carbon seatpost that fits properly. Be aware that this seatpost is VERY FLEXIBLE when you're riding. In my case, it flexes forward-back over road bumps, and noticeably bends side-to-side under hard in-the-seat efforts. You can even see it bending while riding. (I'm 6ft, 180lbs and a very smooth rider.) A very weird feeling. The result is some dampening of road vibration, but I have to wonder how much stress this amount of flex puts on the carbon frame seat tube and binder bolt. It flexes so much that I removed it and will not use it on my nicer bikes. I can't even imagine considering this for a gravel bike or MTB.Second, the manufacturing is a bit sloppy, particularly around the seat clamp. See the photos - holes are not round, and the mating surfaces were very rough. The post itself was nicely finished and the diameter accurate, so it fit smoothly (with some carbon paste) into the seat tube.Overall, this is a good example of, "you get what you pay for", and it's probably fine for a metal bike frame. If you use it, I do recommend checking this very flexible seatpost regularly for wear at all junctions, just to avoid a potential catastrophic failure.

I was just unlucky to have been supplied a seat post with a defect. It broke on my second cross-country ride. On closer inspection it appears that the layup was too thin where the post broke.Otherwise the item is light and well made. It's a shame, the seat post definitely made the ride more comfortable. I hope my experience is a one-off. It's being returned and the alloy one it replaced is going back on.Thing is, it probably wouldn't have broken if used on a road bike, but it does say it's appropriate for MTB use. I'd advise caution.

After a lot of deliberating about this seatpost I bought one with low expectations, £24.00 is extremely cheap for anything made of carbon fibre after all.Out of the box it is noticeably lighter than an alloy post and the external finish is extremely good, no over lapping or misplaced carbon sheets. Internally is where the construction isn't what you'd get with far more expensive posts but there is nothing about it that suggests it is flawed or will break.It fitted the bike perfectly and stays firmly in place with 5nm of torque on the seat clamp and carbon paste. It was also very easy to get the saddle at the right angle, something I was unsure of given you can't get a hex key on the front adjuster unless you have a saddle with a hole in. Thankfully it is easily done with your fingers. 10nm of torque on the saddle rail clamp bolt and it isn't going to move.First ride using it and placebo or not there certainly felt like a bit of extra comfort.I'm genuinely surprised and pleased at how good this item is and anyone looking for a new post could do a lot worse than this one.

...but similarly priced to a decent ally seat-post. So they were worth a try, and I haven't been disappointed. The culprit for the weight is probably the alloy seat-clamp, but it's no bad thing. They seem to absorb vibration better than the ally post they replaced, so am pretty happy about it – given the price of this seat-post.As with all carbon parts, just remember not to over-tighten when fixing to your bike-frame.

If you could give a product zero stars this would be it. This seat post is NOT fit for purpose, it looks the part but in no way should you buy this seat post!!! its a plastic post with carbon lookalike covering. The bracket for attaching the seat is useless as you cannot actually tighten one of the the allen bolts. Ask for your money back as its a copy of the real thing.. in no way is this a Genuine Easton EC90 seat post!!!!

For the money, I am very happy with this seat Post. As for what it is, it is far cheaper than a lot of branded carbon and even aluminium posts, the quality is very good.I fitted this post as a budget weight saving for my single speed and I am really happy that I did. I can't comment too much as to whether it adds much comfort as the frame and saddle are both very plush on their own but on a bike of this type, it was a good low cost way to save a couple hundred grams.On my main bike, I have a more reputable carbon seat post and in all honesty, the quality difference is noticeable but the build construction is still very good.I would recommend this post if you're itching to get some easy weight savings but don't have a lot of money to spend. The look of the post once fitted is also very nice, it is one of the more "in your face" style components that sticks out amongst the rest of my build.One thing to note is that the saddle clamp isn't great on this post, I fitted a Fabric Scoop to it which doesn't have a central cut out, but it is clear that it is much easier to fit if your saddle does have one. For this, I had to tighten the front bolt first to get the angle of the saddle correct, then put the rails into the clamp and then lastly tighten the rear bolt to secure it in place. If you have one to hand, a torque wrench is highly recommended for this.For anyone concerned about the structural integrity of this, I weigh 83kg and often use the bike it is fitted to for my commutes with around a further 3-4kg on my back. I don't have any concerns of it failing on me.
