Nishiki Beta NFS

This is my favorite bike hands-down. What does NFS stand for you say? NEED FOR SPEED. And the "Beta" signifies it as an EXPERIMENTAL bike frame. It's all original except the seat. I added the cyclometer & bottle cages and the twin Zefal quick fill CO2 cartridges. So you can ditch the the air pump. It does have 3 bottle cage braze-ons. See the one the rear. The Michelins will inflate to 110psi! They give very little rolling resistance.

I purchased it new at Sun & Ski Sports Expo on Burnet Rd. in Austin, TX in 1993. It was my first road bike and my first experience with clipless pedals. I will say this is the fastest bike I have ever ridden. I mean freakin' bolt of lightning fast. With a full Shimano 105SC groupo it's a top tier bike. The steel frame & fork is ultra-responsive and forgiving for long distances.

I've only put about 160 miles on it. It has a Cateye cyclometer. It was designed as a Triathlons & Time Trials, but it's more than comfortable for centuries. I also used it briefly as a commuter. I remember dodging deer early in the mornings on Bee Cave Rd before the sunrise. Bloody scary.

Look at the size of that drivetrain! My top speed on 360 is 54MPH without hardly trying.

Article abstract from Bicycling Magazine:
"The bicycle is priced at $949 and is appropriate for road racing. The 650C wheels allow lighter weight and lower air drag. The balanced frame provides quicker acceleration on the well-proportioned bike."

1989 Schwinn Paramount Pro Aluminum

This is one of the earliest true 18 speed mountain bikes and one of the earliest aluminum frames. It's almost new and is bone stock as it came from the shop. All the specs are identical to Schwinn's build list. With ONE exception being the tires. Those had to be replaced due to dry rot.

It has less than one mile on it and I believe it to be the best example of this model you will ever find again. As near as I can trace this was the only year of production for the 1.86kg Pro. This bike is super lightweight, much lighter than contemporary models and can be made even lighter yet by swapping to an alloy handlebar, etc. But if your're a purist like me, this is as good as it gets. I removed the chain to show that there is NO wear to the chainwheels or rear sprocket.

I researched the patent number on the frame and although PDG (Paramount Design Group takes credit for its design it appears that it was actually invented by none other than Gary G.Klein. He applied for this design on 11/7/77 and was granted the patent on 2/19/85. Kleins are of the finest bikes on the planet. They are top tier. After reading about the invention of the 1.86Kg Pro, I was amazed at how much thought, geometry and engineering physics was put into cycling.

Here's how Gary introduced his invention: "The frame of a racing type bicycle is made very rigid to increase the power transmission efficiency and to improve the handling and riding characteristics. The preferred configuration uses large diameter tubing in aluminum alloy to achieve a lighter, stronger and much more rigid frame than prior art."

Patent No. 4,500,103
This is one of the most ergonomically correct bikes I've ridden.
