RIM
Comprising of the upper and outer edge, race wheel rims come deeper than training wheels to cheat the wind.
HUB
The central part of the wheel consists of the axle, bearings, and hub shell to which spokes are attached.
JARGON BUSTER
WATTS
The figure is used to express power. Race wheels with aero benefits can save you watts by making you go faster for less effort.
YAW ANGLE
The direction the wind moves in relation to the direction the wheel moves.
TUBELESS-READY
Tubeless-ready wheels don't need inner tubes. They just need some sealant squirting inside before inflating. In the event of a puncture, you can always stick a standard tube in.
SPOKES
A number of rods are threaded from the hub to the rim to strengthen the wheel. Race wheels often have bladed spokes to reduce drag.
FULCRUM SPEED 55 DB
£1,899.99 The Speed 55 DB wheelset features Fulcrum's 2-Way Fit system which, according to Fulcrum, means they should run well as tubeless or with tubes thanks to extra precise engineering in the valve area. A 19mm internal width is bang on trend and an asymmetrical spoke pattern with 21 at the front and rear should improve balance and stiffness. On the road, the Speed 55S provides a very smooth ride, enhanced by USB ceramic bearings. The freehub whistles quietly, which is appropriate for the regal ride experience, and when you want to crank the power-up, engagement is rapid. They're no trouble at all in the wind, and we think the Speed 55 front wheel would be ideal paired with a rear disc wheel for very fast days. They're not cheap, but you're getting a super-refined ride feel for the premium. i-ride.co.uk

How to Carb Load - Packing your working cells with carbohydrates in the build-up to your big race is a proven strategy to race stronger and faster...
Whichever distance triathlon you're racing, the intensity and duration of your activity will see your body tap into its stores of carbohydrates (in the form of glycogen) to power your effort. While it's possible to top up your tank on the go, it's better to start your event with your stores full to the brim.
The Olympic Champion - On 31 July, Great Britain's Alex Yee put together arguably the greatest one-day performance we have ever seen at an Olympic Games to win gold. And we were there at the finish line to speak to tri's new poster boy...
The opening line of the race report read how 20 years on from New Zealand’s first and only Olympic triathlon gold medal, Hayden Wilde had put in a careerbest performance to regain the title for his nation. Then Alex Yee comes around the corner.Yee’s charge, seemingly from nowhere on the final lap of the 10km run in Paris, didn’t just help him become the most decorated Olympic male triathlete of all time, and didn’t just cap a rivalry that has been building for six years, it left seasoned watchers of swim, bike, run in awe. It will go down as one of the greatest triathlon races; Yee, still just 26, as one of the greatest triathletes. His medals from Paris added to the two from Tokyo, leaving his haul at two gold, a silver and a bronze, and counting.
