Team McCall USA
Gordon McCall was put in touch with me through my friend Dan Kyle. Dan is a motorcycle tuner that knew that I knew a lot about building bicycle frames as well as motorcycle science. see: Team McCallUSA
Previous Record Bike
Fred Rompelberg is the current record holder. 268.831 km/h. 167.044 mph.
This is as close a scetch of Fred's bike that I could make from photographic details.

The Frame
The frame will be constructed of 4130 tubing. The goal is to make the bike as light as possible, as stable as possible, as fast as possible, and most importantly AS SAFE AS POSSIBLE.
At speeds over 170mph, the forces going through the frame are huge even on apparently smooth surfaces.
At this point, the bike is going to have front suspension and a solid rear for maximum power transmission. The tire in the rear will be doing most of the work.
The Wheels
Marchesini 125 GP forged magnesium Wheels, 2.50”x17”
The Tires
Donlop 125 GP tires
The Fork
Ohlins 125 GP gas fork
The Yoke
A special lightweight yoke is going to be required. The goal is to have a 1.125" steerer extention so that different stems can be redily avalable for rider position adjustment. I think that this makes sence.
Risse Racing (not contacted yet). 1.5" offset.
If not available, then DKG
The Brakes
Brembo 125 GP
16x18 Radial brake master cylinder for single caliper
155mm rotor front?
The Headstock & Bearings
The larger the headstock the better. Current bicycle technologies are durable and light. The Cane Creek Double XC 1.5" Flush headset should maximize the headstock area.
The Triple Trees
DKG?
The Dropouts
In house design, watejet cut from .3125 4130 Cro-mo.
The Drivetrain
Cranks- Dura-Ace Track cranks
Jack shaft-
Sprockets- Paragon, Phil Wood, or White.
