I can confirm that my MIT Atlantis uses a 26.8 mm seatpost. I don’t know if 
they all do though

Re: [RBW] A Bit Irked that Riv Changed the Seatpost Size

[Nick Payne]

The seattube on steel frames is 1-1/8" (28.6mm) external diameter. If the 
builder uses 0.7mm wall thickness for the seattube, that gives 27.2mm 
internal diameter; 0.9mm gives 26.8mm.

I found that the 26.8mm seatpost supplied with my Appaloosa was a slightly 
loose fit in the seattube, and as I already had a nice Suntour Superbe Pro 
post in 27.0, I reamed the seattube slightly to take that seatpost.

I sure wish Riv hadn't changed the seat post diameter from 27.2mm to 26.8mm 
on their frames. Doing so really limits the available seat post options. 
 One particular suspension seat post I use is only available in 27.2mm. 
 Baffles me why Riv chose to do that.  Glad I got my Hillborne before the 
change, but rules out an Appaloosa as my next bike.

Re: [RBW] A Bit Irked that Riv Changed the Seatpost Size

[Patrick Moore]

You are very welcome. Note that neither the Loctite nor the "gel with
roughage" solutions make it hard to remove the seatpost, only with Loctite
you have to smear more on after you remove, because it dries out, while the
gel seems not to dry out, at least, not as fast. So experiment and, if you
don't like it, wipe clean.

Re: [RBW] A Bit Irked that Riv Changed the Seatpost Size

[EricP]

Patrick,

Thanks for the suggestion. Will look into that. Yes, it needs to be either 
an undersized post, or an oversized person on top for slippage to happen. 
Still haven't totally settled on the final saddle choice for the Clem, but 
for now am just going to keep using the factory stock model. Works for me 
on rides up to 20 miles so far. Once decided, might use the Locktite 
solution.

Re: [RBW] A Bit Irked that Riv Changed the Seatpost Size

[Eamon Nordquist]

I thought the MIT Homers use a 27.2 seatpost. I could be wrong - the 
description doesn’t say, as far as I can tell.

 Instead, find a local fabricator and request the following:

 1: Get a section of 27.2mm tubing and cut it to length (300mm or 
 thereabouts)
 2: Cut the tube from the seatpost you want
 3: TIG-weld the 27.2mm tubing to the base of your seatpost

 the suspension posts posted on eBay above are all awful compared to the 
 market leading suspension posts from Cane Creek and the like. They're not 
 even really the same thing from a functionality perspective. Linking to 
 them is a total straw man. 

 Cane Creek's design has been around for 20+ years, and is a well 
 proven, tunable, and serviceable technology. Lots and lots of people love 
 them and I suspect that's what OP was hoping to use.

 If you want a cheap but good one, you can get a Kalloy Uno 
 
 .

 If you want a middle range, you can get one from Dajia 
 Cycleworks(note most sizes currently out of stock).

 If you want blingy dingy doo, you can get a Nitto 
 
 .

 There are many vintage 26.8 seat posts available on eBay, 
 including Campy

Re: [RBW] A Bit Irked that Riv Changed the Seatpost Size

[Matthew Williams]

I would not recommend milling the inside of the seat tube. You'd be weakening 
the structure of the frame and the milling would be difficult and more expense 
than it's worth.

Instead, find a local fabricator and request the following:

1: Get a section of 27.2mm tubing and cut it to length (300mm or thereabouts)
2: Cut the tube from the seatpost you want
3: TIG-weld the 27.2mm tubing to the base of your seatpost

Meanwhile .0004% of bicycles (Rivendell's contribution to the ~100,000,000 
that are produced every year) come with 26.8 lol

Re: [RBW] A Bit Irked that Riv Changed the Seatpost Size

[Eric Daume]

Modern mtbs have really coalesced around 30.9 or 31.6 seat posts. A few are
bigger are smaller, but I’d guess 80% of new mountain bike have one of
these two sizes.
