Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Seatpost replacement

Hello everyone,

I've just had my Dura-Ace alloy seatpost break on me. It was getting on in years I suppose so I'm not that upset and from what I've read they don't have the best of reputations in terms of durability.

So I'm looking for something to replace it with. I just want something that will do the job to replace it, nothing fancy so I'm after something relatively cheap. So I went into the LBS and got the cheapest one but it looks like it's going to be too long for my frame, so I'll take it back.

But it looks like there are different adjustment options on the seatposts. Basically with two bolts or one. Can anyone suggest one or the other? And is there any special type of setapost that you think I might fancy? I'd rather stick witha alloy for now rather than carbon as I occasionally attach a rack to it.

Never bought one on its own before so I'm not sure what to look for other than length now.

The best designed seatposts have 2 adjustment bolts, one in front and one in the rear...like a Thomson for example

Thomson makes a great seat post but it doesn't offer much in terms of setback (on their setback model) so keep that in mind, otherwise it's a solid but really light seat post that's easy to make small saddle position adjustments.

I have a Thomson, best seatpost you can get.

Before that I had a Salsa Shaft seatpost. It was pretty nice too, and cheaper

get a thompson and you'll never have to worry about your seatpost again.

that said, pretty much any of the alloy posts with the two bolt design is going to be pretty good. but for about $80-100 you can just buy the last seatpost you will ever need.

Thomson Masterpiece. Shave off some weight, get a new seatpost. 'Nuff said.

Thomson make a great post so its a fine choice, but it is just a ripoff of the original Syncros (not that it makes a difference). Fortunately Syncros is now out of Pacifics hands and back to more of its roots with Tom Ritchey.

My Syncros Ti on my MTB is still the best original 2-bolt post, and makes a great road post. However, very few people in reality should be using zero setback posts on road bikes. The vast majority of bodies out there should be using a setback post for proper fit, and road bike geometries are evolving only to increase that use with steeper seat tubes.

So Thomson is good, but with a few awful exceptions almost any seatpost today will hold your saddle level and secure with no problems.

oh, and "too long for my frame"....you can just cut down those posts.

Who else makes a 2 bolt design like Thomson? I picked up a writchey because it was $20 and was a two bolt design...well let me tell you, their two bolt design is worthless and a far cry from what Thomson does.

BBB Bike Parts makes 2 bolt seatposts. I have one and love it. But for weight reduction I should have gone for Thomson, and as soon as it trashes, I will.

I like the old style cuz you could flip it forward or back and THEN adjust the position on the rails. the old ones kinda bought you a free2" in either direction.

Thomson here.

Takes a bit to dial in, but once you do, it's perfect!

I'm shopping for a cheap but light no-setback post in silver and am eying these.

Thomson. Undoubtedly. But like someone said, their setback model has barely enough setback. My frame has a 74 degree seat tube and I need the saddle all the way back on the rails even with the setback post. If my seat tube angle was 74.5 or 75 I wouldn't be able to use the Thomson.

I have an aluminum Bontrager Race seatpost. It utilizes the 2-bolt design and is about the same weight as a Thompson. Bought it for $11 on ebay though.
