PVD Land Speed Record Bike

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.

It has not been decided if the rear wheel postion will be fixed or adjustable.

The Drivetrain

Cranks- Dura-Ace Track cranks

Jack shaft-

Sprockets- Paragon, Phil Wood, or White.

Ceramic Bearings

Expected cost - $600 for both wheels, $300 for both bottom brackets.
