Hi!

I am in a bit of a dilemma for finding the proper size of seat post for my Torker and Hutch frames. I have taken a bunch of measurements of posts with my digital calipers but can’t find anything that will fit correctly.

I have checked many new 7/8 posts that are stamped 22.2 but when measured they are actually 21.9 to 22.0 at best so they won’t work at all. I think these manufactures are playing it safe and under-sizing their posts.

My 84 Hutch Pro Racer frame can tighten up enough to hold the stainless steel post I have been using but the two sides of the slit cut into the frame touch or about touch when tightened. That post measures 22.1 and my Torker 26 also has the same problem. The end of the run Torker 26 frames required an oversized post like my Hutch frame.

The posts shafts on my frames are the proper size and are not distorted or damaged in any way and both frames are in excellent condition.

I found a beat up cheap looking 22.6 that fits great but I am looking for a nice post that looks like new or one I can re-chrome that is not pitted up at all.

I also tried to use a shim but the thinnest shim I found was too thick. I am sure I can use a slice of soda can but I want the right size of post and not a shortcut fix.

From what I understand a real Hutch seat post, or some of the old GT posts were larger than 22.2. Kuwahara also made a 22.4 but I can’t find a good one.

As we all know anyone can put a Hutch or GT sticker on a plain chrome post but for the price of a good one I can’t take the gamble that it is the real deal and will fit my frames unless I know the actual size. I also have not had any luck getting anyone with a post that has the potential to fit to measure it for me. I understand a lot of guys don’t have digital calipers. I picked my set up on Amazon for $10 and they work great! Before I get bombed with comments that $10 micrometers are junk let me reassure you I have checked calibration over and over and they are precise. If anyone is interested in a set I can give you the link to the set I got, they have great reviews.

I found a post last week that was supposedly a Pro Raider post that was stamped 22.6 but when I slid it in the frame it was loose for a 22.6 post so I checked it and it measured 22.2 so I can’t always go by the stamp on the post.

So what I really need is a chrome or stainless steel seat post that measures out at 22.4 to 22.6, preferably straight but layback would also be fine and I don’t care what sticker is on it I just need it to look good. If I can’t find something I may need to make my own post if I knew where I could get some aircraft grade 41-30 tubing with the proper wall thickness. So if you know where I can find something any help or advice would be great.

Thanks for your help!

I had the same problem on my raleigh cruiser. I ended up using a tioga layback and had an old shim from an elina UL and now it fits exactly.
Is an elina shim too thick ?

This may not be useful to you, but myself and at least a few others have had the opposite problem with Revcore posts.

They knurled them where it meets the frame, which makes them bigger than most frames will happily accept. I've seen them beaten in, filed down and cut off trying to make them fit.

Those are definitely a high quality option

I have a cheapo chrome layback seat post coming in a few days for my pre serial Pro Racer. Labeled 22.2, I'll let you know how it fits. I mic'd the seat mast on the frame ~22.6mm.

SoGnarly · 2012-10-15 5:50am

The seat post is an old Team Cycle, labeled "22.2" but is an actual 22.02mm. It is a little loose in the frame, an actual 22.2 would be alot nicer.

Here's some pics, post pushed to one side, centered and tightened up, respectively.

(I remembered why these clamps sucked BITD, you can't get a wrench on the nut side. lol)

maybe find somethig made in the usa? maybe it will be truer to the 7/8? never had this problem

SoGnarly · 2012-10-16 5:53am

Are there any budget-friendly Made in US options? $100+ for a Hutch post is absurd IMO.

The problem I am having is finding an oversized 7/8 post. A true 7/8 post should be 22.2mm and chrome plating adds .05 so in a perfect world a 7/8 seat post that is chrome plated should come in at 22.25 but even USA made tubing has lots of variance.

I need a 22.4, 22.5 or 22.6 post. I don’t expect to find any tubing in this size unless I luck out. It seems that most USA made stock is just under 22.2mm.

I jammed a piece of shim stock in mine. I think it was a Chevy starter motor shim.

Thanks my friend! But I am looking for the correct size of post rather than a shim. I know the correct size posts are out there I just need to find someone who has one and can verify it for me with some digital calipers even if it is as expensive as a Hutch post.

Thanks again!

I have real nice 22.6 seat post I beieve was made by Hutch. I've had it on Ebay. It may be a little pricey but, it is Hutch. It is very rigid with thick walls and knurled. It says 22.6 right on it. a A really nice vintage item.

Coco · 2013-01-08 11:47am

You'll have to use a shim. Tube sizes are usually nominal so there is always an accepted variance from the mill.

S&M BEN · 2013-01-10 6:01pm

I had to use a piece of a pop can for a shim to get my Hutch post to fit snug in my trickstar!

Scraplord · 2013-01-10 6:11pm

Lots of older bmx bikes take 22.4 mm or 22.6 mm seatposts. It`s not that uncommon. My 1990 Boss takes a 22.6mm post. So do some Schwinns and some Redlines.

The problem is finding them. Fluted posts are out there but it is tough finding a 41-30 chrome plated post. I am sure they are around but not to many sellers have calipers to use to check the post. I got my set on Amazon for $10 and they work great.

Mine is a Redline fluted post and it`s stamped 22.6 right on it. Keep looking. They`re out there.
