Origin8 Pro-Fit Alloy Seat Post

I've been on a journey with a 2003 GT Palomar. I didn't care for how it rode, fit or shifted when it was given to me new in 2004. So after a few short rides it was put in shed.When it saw daylight for a ride in 2013, it was hit on the rear wheel by a car. The wheel was bent so badly that I was barely able to limp it home with the V-brakes removed and pads released. Then it went back in the shed.In 2021, it saw daylight again as I was going to junk it as the cost of a wheel straightening, or new wheel wasn't justified on a 20 year old $230 bicycle. But, it had less than 100 miles on it and seemed to be comparable with some new bikes in the $500 and up range. So I cleaned it up and figured I'd try to fix and sell it.I watched videos and fixed the indexed shifting and straightened the wheel. Then gave the old GT a full tear down and service.On a test ride, it was smoother and quieter than anything I'd ever owned and I figured no one would give me what I felt it was worth now. It, also had a Chrome Moly frame that I prefer over the ride of the newer aluminum frames. So, I decided to try to make it fit me better instead of selling it.One of the main things I found was the stock seat post was too short. So, I looked for a longer one.I originally wanted a Thomson post, but they didn't offer a long 26.8 and I wasn't going to pay what people wanted for a used Thomson 410mm, 26.8 seat post on ebay. So, I purchased the Origin8 400mm.I watched seat adjustment video's and installed the Orign8. The post gave me more leg room and the bicycle became more enjoyable to ride.The seat post is about 1/2" below the maximum height line and is doing fine with my 230lb weight. The bike is used on easy trails and paved back road riding. It has gone on some mild single track, but is mainly used as a crusier/gravel bike on New England back roads. Right now, the average ride is 10-30 miles when it goes out.So far, 5 stars for this post. If I have any issues with it, I will update.The seller gets 5 stars because the post arrived well packaged and in new condition.Suggestions based on my install:When I first put the seat post in, I had it at the maximum line and thought it felt good as it sat me above where I had been riding on the stock post and my legs were extended. However, the bike became even more difficult to ride smoothly which I figured was due to the stock handlebars being almost flat (pic of the bike with no water bottle). So, I ordered a Bucklos 60mm riser bar to use on the existing stem (other two pics).*** Please know I that Origin8 did not offer a handlebar that I was looking for. Which is why I went with Bucklos.***When I got the new bars, I found that they were better, but did not solve my fit issues and the bike was still a miserable, twitchy monster to ride. It was so bad that I couldn't take a hand off the bars to wave at other cyclists, or the bike would try to throw me.So, I watched more seat adjustment video's. In the end, I dropped the seat height about 1/2", moved the saddle forward about 1/4" and the bike felt completely different and far more comfortable to ride.I also played with the seat pitch and rolling my bars, shifters and brake levers slightly forward and backward.In the end, I accidentally learned one day that the bike rides smoothly with no hands on the bars now.If you are fussy about appearances, try to figure out the ride height for your post before installing it. I originally installed mine lower than it needed to be and now that the post is adjusted properly, there are visible zig zag scratches in the paint from when it was mounted lower and the seat was rocked side to side to adjust to the various heights I tried previously. Not a big deal for me, but may be for others.If you grease, or use anti seize lubricant on your post as I do, once you have your seat adjusted, put some tape around the post just above the frame. The tape will let you know if your seat is slipping lower while you are riding. In my case, it took several rides, removing the post each time and wiping it and the inside of the frame to remove excess anti seize compound until the post would remain in place with the quick release closed.Lastly, while you are there, clean and lubricate your seat mount and slides. 2 months after my install, my seat began to creak because I did not do so.For a reference, I'm a 6' 6", 55 year old recreational rider both off and on road, weigh 220-230lbs and the post has been fine so far for a few hundred miles.Good luck and ride safe.

Two-bolt microadjust seatposts such as this are my only choice. They offer infinitely variable angle adjustment and they never slip or work loose. The Oirigin 8 is as good as much more expensive brands.

I looked and looked for a zero offset 26.6 mm seat post for my old bike, and I didn't find much. Luckily, I found this.First, some questions and answers:How is 400 mm measured? From the bottom of the tube to the center of the seat rail clamps.How much did it weigh? 331.4 gWhy was that last question in the past tense? Because I cut 7" of tube off the bottom end. It leaves me plenty of insertable length (4" is the minimum), and it brought the weight down to 236.9 g. Makes me wish I cut off another 1/2", and I could have said I reduced the weight by 100 g.What is the finish of the inserted tube like? It's got grooves or ridges, whatever you want to call them, like a tube turned on a lathe? How deep? How rough? If I run my fingernail down the tube, I can hear a zipping sound, but I can by no means catch my fingernail in the grooves. When the tube is wiped with a cloth. it feels smooth, and no fibers catch on the surface.How does the seat rail clamp work? It is a rocker pulled into a saddle, and tightening the front screw while loosening the rear brings the saddle's nose down.Are there ridges on the rocker and inside the saddle, or is it smooth and infinitely adjustable? The latter.What country is it made in? Taiwan. Why Origin8 wouldn't advertise this fact, given the excellent reputation of various Taiwan bike parts manufacturers, I don't know (I love Dia-Compe and higher-end Tektro stuff). Even more mystifying is asking the Amazon community what country and getting the answer, "I don't know." Really, I wasn't asking you personally. I was asking people who know.I am more than satisfied with the quality of this seat post. It is well built, and it looks good on the bike. It is very easy to install and to install a saddle on it. All the parts stay together, no nuts or bolts have to be removed, and the rocker portion cannot fall out. It's easy to adjust the pitch (up/down angle) of the saddle. A 5 mm Allen wrench does it all. Tube diameter is accurate. It slides into the frame and clamps securely.

It's a nice color it fit the seat post pretty well I sadly can't use it anymore but when I did it was nice i like how stiff the post it what makes it pretty comfortable I recommend for anyone who is looking for a seat post

Very light, fits great with my sit. Does the job

Perfect angle Perfect fit.

The seat clamp mechanism is very intuitive to use.

Great two bolt seatpost
