In our review this week of Kendra and Rene Wenzel's Bike Racing 101, we asked for the definitions to certain racing terms for a chance to win a copy of the book. See book review here.

Here are the Bike Racing 101 answers, but we had some quite enlightening and/or humorous definitions in the answers we received. Here are a few of the choice ones, below the "book definitions," for your enjoyment.

Aerobars - Add-ons for handlebars to help a rider get low and narrow; also called tribars.

--Additional hardware that clamps to the front of your regular bars that allows the rider to achieve a more aerodynamic position. Usually used in time trials or by Freds who want to look cool.

--These bars are only legal for time trial and triathalon events. Use is also highly discouraged for any type of large, fast group ride - someone could lose an eye.

--Handlebars which improve riding position enabling the rider to cut through the wind easier (or the bars where Errol Flynn and David Niven hung out in Dawn Patrol).

Bonk - To run out of stored glycogen, suddenly run out of riding energy.

--What happened to Lance in the 2000 Tour on one of the mountain stages because he didn't eat enough Power Bars. Basically, the body runs out of fuel, water, electrolytes, etc.

--Another name for "you forgot to eat". That awful moment when you've used up all the energy you've got and you just die on the road (or wish you could). Happened to Baden Cooke while wearing pink in the Giro last year.  [Uh, wasn't that Cadel Evans?]

--A significant drop in energy level due to depletion of glycogen stores. Also, the sound of my hitting the ground after losing the ability to control my bike during a serious bonk.

Clinchers - Modern tires suitable for racing or training that feature an inner tube and are held to the rim by a hooked bead.

--Tires which sit upon a rim by "clinching" it with a bead rather than being glued on by a swarthy mechanic.

--A type of bike tire requiring inner-tubes where the bead of the tire seats along the inside edge of the rim - not a tubular. Also, the action required for the remainder of a race when you realize that you should have hit the porta-john one more time before the start - oops, I guess that would be "clencher".

Echelon - A paceline that stretches out sideways so riders can take maximum advantage of the draft in a side wind.

--A racing technique used when the wind is blowing from the side. Instead of a straight pace line, the riders angle across the road trying to catch as much wind shadow as they can from the rider ahead of them. If you're not in the first echelon or two, kiss the race goodbye.

--A diagonal group formation to provide the most effective draft in a cross-wind condition. The preferred place to be rather than "strung-out-in-the-gutter", but that's a discussion for another time...

--A peloton formation in a cross-wind situation. If the wind is coming from the left, all the riders stack up to the right. If you are the last rider out there and you run out of road, you are in big trouble! Form another echelon.

--Riding formation in which the paceline is angled, so as to minimize a not-quite head-on headwind. This formation, if practiced on country roads in the Berkshires, angers the locals mightily.

Half-wheel - To ride hard enough to keep the front wheel just ahead of the wheel of the rider next to you.

--Very annoying habit when two riders are riding side by side. Normally both front wheels would be aligned on an imaginary line. Half wheeling consists of the annoying rider advancing his/her wheel halfway up the road, so his/her front hub will be aligned to the front of the annoyee rider's tire. Half wheeling comes from either bad riding form or just plain obnoxiousness.

--A potentially dangerous situation if the rider in front does not know the rider behind is there because if the front rider moves to the side and hits the wheel of the rider behind, a crash is imminent!

--a) riding just ahead of another rider, as opposed to riding evenly together; this is not good etiquette in group rides; b) a yoga position; or c) a moderately large cheese.

--The bad habit of slightly pulling ahead of your partner when riding side by side. This continues to escalate the pace until your companion whacks you with a bike pump.

--To continually pull-ahead of the rider next to you in a double pace line, causing the other line to accelerate, then you to accelerate again, etc.

--To ride next to, but just ahead of someone. This is particularly irritating when riding in a double pace-line. If a girl does it to you it's called being "half-chicked".

--A very dangerous way of drafting too closely behind someone, liable to cause a crash (or the bicycle on board Heny Hudson's Half Moon on the famous 1609 voyage).

--When you overlap the rider in front of you, or slow down to cause a similar condition to the rider behind. a dangerous place to be for the second rider. Part of a book title, Half-Wheel Hell.

And the winner is.....Gustavo Cinci! Congratulations, and thanks to all for participating!
