CYCLING PERFORMANCE TIPS

Definition - using technology to gain an unfair advantage in an athletic
event. Also known as technologic fraud.
A couple of excerpts describe this form of sophisticated cheating as well as I can:
- "Rumors and serious accusations of racers using hidden motor systems have been around the
sport since 2010, when Fabian Cancellara accelerated away from the field to win the Tour
of Flanders, and Italian journalist and ex-pro Davide Cassani later demonstrated a
system for RAI TV."
- Here is an example of a small motor that can be hidden inside the frame and give the
rider "...200 watts of additional power to the crankshaft, but due to efficiency losses,
actual power at the wheel is anywhere from 40 to 100 additional watts depending on the
rider's own cadence. Burn time is 40 to 100 minutes..."
- One design is... "the Vivax Assist (formerly known as Gruber Assist) that is nearly completely
hidden inside the frame. It's this concept (or something like it) that 'mechanical doping'
alarmists claim is possibly being used at the highest levels of the sport."
- "In its current form, the Vivax Assist comprises a small cylindrical motor drive unit that
slides down inside the frame's seat tube, tucked away from prying eyes, plus a small
external battery. At the bottom of the motor unit is a small bevel gear that
drives a retrofitted crank spindle. With a simple push of a handlebar-mounted
button, the rider can summon up to 200 watts of extra pedaling power, essentially
transforming an average cyclist into Chris Froome."
- "Claimed weight for the entire system is 1.8kg (3.97lb, complete, claimed)
but even though that's already relatively svelte, such a system
wouldn't be used in standard form."
- But it appears things are moving quickly and the ..."use of electromagnetic wheels
is the 'new frontier' of technological doping. A motor hidden in the seat tube is old stuff,
almost artisan. It's been overtaken, it's a poor man's doping, Ghisalberti writes. The new frontier
is far more technologically advanced and ten times as expensive. It's in the rear wheel:
it costs 200,000 Euros, and there's a waiting list of six months. The first type uses a motor to turn
the cranks; the second is electromagnetic."
I'm sure we will hear more."
