I think if you look closely it's probably actually 25.8.

Nah it's 25.4

Yes, you should have quite a few more options in that diameter.

It's supposed to make a slightly more flexible seatpost, therefore smoothing the ride. I agree, it's difficult to find many aftermarket options.

It's a Cannondale.

I discovered this when I bought my Synapse, and it confounds me.

'It never gets easier, you just get crazier.'

We've gotten spoiled with round seatposts basically available in 27.2 and 31.6 for a while. It wasn't that long ago that one could find 30.9, 27.0, 26.8, and 25.4. I had a Burley Rumba that I rode with my kids when they were young. It had 2 different seatpost sizes! Thomson used to produce multiple sizes. I don't know if they still do.

As mentioned, looks like Thomson does make a 25.4 seatpost. That may be one of the best options.

I presume you're looking for something with no set back, otherwise why not use a Cannondale post? I have a caad 12 with the 'dale post which I find fine.

I have to say I absolutely love the Caad 12.

I put a hylix on mine, per the recommendations on weight weenies. I love mine too, I was on a Cervelo S3 and the CAAD is slick. Nobody realizes it is aluminum.

So this sounds dumb but I'm really weird about stuff matching. On my Allez E5 smartweld I had a zipp service course SL post, stem and bar in the all black color which I was hoping to just swap over to the CAAD. Gonna go with Thomson now. Should be good.

Nobody realizes it is aluminum.


Met a guy on a group ride last summer. He was riding on a Specialized aluminium Allez w/ a combination of Ultegra and DA kit - black on black - just like your bike. From 5 ft away - looked like a carbon fiber bike.

Looks like the Thomson seatpost solved it for you. Can't resist posting to say I love my CAAD 12. It replaced an old Cervelo Soloist carbon that I loved but was getting old. The CAAD 12 feels much quicker and I don't notice any more road vibration than with carbon. I have been surprised by that although reviews had said as much. My CAAD 12 came with a stock Cannondale seatpost but it was carbon anyway so I have not replaced it. I took the money I saved from not buying an expensive road bike and bought a tri bike. So no money really saved but I do have 2 new bikes instead of 1.

Are you talking about the uncut steerer tube?

I am always afraid of choking on food while riding, so leave the steerer long so I can self perform the heimlich while riding.

I won't cut it off for a while until I know for sure I want to keep my bars low.

Someone had to be an ass, I thought. Great picture. Serious question, how did you get your bike to stand up?

Extra long steerer makes for perfect balance...
