Title: -----unknown seatpost-----
Post by: bmxband1t77 on December 07, 2014, 10:25 PM
Hi can any of you help?
I won this on Rad but seller neither myself know what it is?
The closest thing I can find is its very similar to a type of Redline Seatpost but this ones unstamped and been slightly cut down. As you can see, the welds and chrome quality don't suggest cheap import copy so what is it?
Thanks

Great, tank you!
How would I know? There seems no defining features apart from the shape.
I'm sorry ELF brand escapes me at mo, Mebbe in just forgetful but it's not ringing any bells tonight? Is this good? I quite like it tbh.

It don't think it is an Elf post, the Elf posts were very similar the top tube was hollow.

Funny you should say that?

Post by: bmxband1t77 on December 11, 2014, 01:46 PM
lol. Yer, that's lekky tape to mark the official safe insertion off another post. But there's plenty of tube below the seat stay at that position in the pic.
Hoping there'll be enough room for me when it's done.

If so, it would be called an RL "Hammerhead" seatpost  ---- first appeared in 98, and apparently stamped from the start

What's knurling?  >:D
Title: Re: -----unknown seatpost-----
Post by: bmxband1t77 on January 06, 2015, 08:31 AM
It's a crisscross pattern cut via a tool onto the metal surface to improve clamp grip. Most BMX handlebars had this as standards to prevent bar slippage which us bmxers is extremely dangerous!
Hope that helps.

Sorry, i saw the word knurling and just couldn't resist  >:D

Hope you find out what type of post it is. My level of knowledge on anything after 85/86 ish is zero.

Post by: bmxband1t77 on January 06, 2015, 02:20 PM
Lol no worries. It's incredibly like a redline hammer post and welds are top notch. The only thing missing is  a RL stamp on that circular bit in the pic. 😶

with it being cut down this post could be one of my old posts, I had them on a few of my bikes and cut them all down.  If it is, it is a 4jeri post. I bought 4 brand new ones around 2003, can't remember where from, but was from a shop online 4.99 each.  I think rupture? or ruption? used to sell a version too around the same time. Some of the capping was quite straight and one was more curved like the RL but all 4jeri.

had a look back and found 2 pics of the 4jeris on bikes, you can see the inconsistency of the forward overhang on the 2 below but both bought new at the same time.

Yeah Ruption did one too, they were knurled at the end though.

Post by: bmxband1t77 on January 10, 2015, 07:56 PM
Cheers guys. Likely it's one of orgasmdonors as its a cut own by an inch or two. Googling 4jeri Seatpost returns a big fat nothing! Not even BMX museum but someone on FB got me a link but it wouldn't open.

Tryin to remember who I got it off now LOL. Been so many parts in lately!

all 4 posts I had were sold as 4jeri (no stickers or packaging just sold as 4jeri from an online bmx shop, can not for the life of me remember who) and I looked for more shortly after and could not find any. All 4 were slightly different but none had knurling. I did not like lay backs and these cut down gave a a discreet couple of inches of knee room. nicely made tho with tidy welds but who knows what stock was cobbled together n rebranded back then
