ACS Rotor 55 Stem
ACS updated the ever popular Rotor 45 Stem and solved what became a problem with the ACS Rotor - The stem had to be raised considerably to allow the Rotor to operate correctly. The ACS Rotor 55 Stem had a Specially Angled Forged Aluminium Head position. This lowered the handlebars without losing the stem shaft height required to run the Rotor and aided responsiveness and control. The ACS Rotor 55 Stem also came with a built-in adjustable rear cable guide and a hollow chrome moly stem bolt.
Unfortunately, these also became famous for the hairline cracks that would appear in the clamp bolt holes where the stem slants downwards.

ACS Rotor 45 Stem
Feast your eyes on the latest ACS innovation: The ACS Rotor 45 Stem. Designed to use with the Rotor, this stem comes complete with a Pott's Mod for the front brake cable plus a built in cable stop that positions the rear brake cable away from your knees and directly over the rotor anchor bolt.
Say goodbye to tonnes of power robbing flex. A specially designed chromoly shaft allows for precise Rotor positioning and a super tough, forged aluminium rounds out the package.

Flying W ESP Stem (3rd Generation)
Flying W BMX products are the makers of the ESP Stem and were out of Washington state.
They started selling their stems (I believe) early to mid 1983 mainly advertised in ABA Action newpaper.
Owners were Marty Ehnat (racer) and his father Walt (ABA announcer and track director in the Pacific North West).
"Eddie Sigmund Products"
Eddie Sigmund was a well known Skyway racer and had a company around the mid- 80's.
His company was called ESP for Eddie Sigmund Products.
Eddie Sigmund Products is not the company that made the ESP Stem, Flying W made the ESP Stems.
Although Eddie was mainly a racer, he was featured in a Skyway freestyle ad.

Flying W Model M ESP Stem (Generation 2)
"Flying W/ESP stems were made in Tacoma, Washington in the early 80's by Walt Ehnat (Flying "W") and his son, racer Marty Ehnat. The ESP stem was basically the first XL/Long stem introduced to the BMX market (around '82), and a lot of pros used and endorsed them."

"The Model "M" (for "Marty") 2nd generation round logo stem. Only 20 were produced with the stamp on the side. The quill was made long as they were installed high with flex fighters."
~ email attached to http://bmxmuseum.com/reference/1106
"Your E.S.P Stem is unique in the industry developed by a Pro Bmx'er with the aid of space age technology and material.
The head parts are 7075-T-6 Aircraft grade aluminium - this material costs 5 times as much as 6061 Industrial grade aluminium most stems are mad from. This is why your bars will stay put with our Stem.
The shaft is stainless mandrel drawn Alloy Steel. Similar to gun barrel material.
All bolts are T5... The allen head bolts are 5/16 American thread.
Like buying a fine watch or gun - our product may cost a little more but you probably have bought your last stem.
No Stem should be elected more than 1 5/8" or we cannot honor our guarantee"

Pro-Neck TUF-NECK T-N Stem
A former Superbyke investor formed a new company called Tuf-Neck, Inc. that made arrangements with Bakton to purchase, market, and distribute Tuf-Neck stems. To stop confusion, Tuf-Neck, Inc. changed it's name to Pro-Neck, Inc and marketed the original Tuf-Neck stem as the T-N.
This stem had the same square corner aluminium block and a hollow bolt secures the block and shaft together as one. This came with a T-N sticker on the block.
