ONE DOWN!!
In less time than it takes to bake a frozen pizza, all 800 spots in the 2011 Test of Metal race were gobbled up on Saturday (Jan. 1).
It took 23 minutes for the race to completely sell out, breaking last year’s record time by one minute and thirty seconds.
Race director Cliff Miller was pleased with how swiftly the 800 spots went.
“It was fantastic,” he said. “We have a brand new record and I was a little surprised that they went so fast.”
Miller and the organizing group behind the race were stationed at the Howe Sound Brew Pub on Saturday (Jan. 1) to track the entries pouring in and he said it was fun to see how well received the race was.
“Everybody was really happy with the way the registration went,” he said, adding that he hasn’t yet perused through the entry list to see the makeup of the riders participating for the 2011 race.
Registration for the race began at 6 p.m. and the popularity of the Test of Metal was proven after the early-bird locals only registration sold out in 187 minutes on Dec. 1. This year’s race is scheduled to take place on June 18.
The race, which has been running on its current course since 1996, attracts mountain bikers from around the world and has become the most anticipated event on the B.C. mountain biking calendar. The 67-kilometre course features over 1200 metres of climbing and 35 kilometres of single-track racing.
Last year’s race attracted riders from as far away as Switzerland and Hong Kong. A total of 64 racers came from outside of Canada and almost a quarter of the Canadian entrants were from outside the Lower Mainland.
Past participants include Canadian Olympians Alison Sydor, Geoff Kabush, and Seamus McGrath, as well as notable celebrities like Vancouver Canucks’ icon Trevor Linden.
Miller also praised the work of the more than 300 volunteers who help make the race thrive.
“This race wouldn’t happen without all of our wonderful volunteers,” he said. “All the volunteers and the people in Squamish help make this event so great.”
Miller added that the next major focus for the mountain biking community in Squamish is on the Orecrusher, which is the first race in the Hell of a Series bike races. Taking place on May 14, the Orecrusher kicks off the series and is a lap race through the trails of the Cheekye Fan. Registration for the Orecrusher opens in March.

News
South African Croeser is newest signing for UK-based squad
The Orange Monkey-Cannondale cross country mountain bike team has been accepted by the UCI as a registered mountain bike team for 2011. The UK-based team, introduced in 2004, has grown each year and will undertake a demanding schedule of races at home and abroad, including five of the six World Cup events.
South African Rourke Croeser, a multiple-time national champion, is the newest addition to the roster. He will race in the elite/under 23 category along with Ben Roff, who is moving up from the junior category. Paul Beales and Chris Andrews will compete in the elite category while Alex Baker will represent the team in junior races.
Croeser is beginning his early season in South Africa before heading to the United Kingdom in May. The rest of the team will head to Cyprus for the Sunshine Cup series.
Team Manager, Will Cooper will head the squad, along with two mechanics and a full pit set up at both domestic and European races.
The team continues to be supported by Cannondale bikes, which has stepped up to a title sponsorship role. "It's great to see a lot of hard work and dedication, both on and off the bike, be rewarded as the team progresses to UCI status," said Mike Cotty, Cannondale's Marketing Manager. "I'm certainly looking forward to seeing the guys, and Cannondale, on the podium at many more races in 2011".
The team is also sponsored by Schwalbe Tyres, Bioracer Clothing, KCNC Components, Pyreneescycling.com, Zipvit nutrition, Mavic Wheels, Casco Helmets, Squirt Lubricant, XCRacer.com, Pedal Precision, Magura Brakes, CycleOps Power and No Tubes Sealant.
In keeping with the team's clean cycling stance, its riders have joined the anti-doping organization, Bike Pure, and will carry the blue wristband as the symbol of a Pure cyclist.

Advantages of light wheels( discuss )
The advantage of light bikes, and particularly light wheels, from a KE standpoint is that KE only comes into play when speed changes, and there are certainly two cases where lighter wheels should have an advantage: sprints, and corner jumps in a criterium.
In a 250 m sprint from 36 to 47 km/h to (22 to 29 mph), a 90 kg bike/rider with 1.75 kg of rims/tires/spokes increases KE by 6,360 joules (6.4 kilocalories burned). Shaving 500 g from the rims/tires/spokes reduces this KE by 35 joules (1 kilocalorie = 1.163 watt-hour). The impact of this weight saving on speed or distance is rather difficult to calculate, and requires assumptions about rider power output and sprint distance. The Analytic Cycling web site allows this calculation, and gives a time/distance advantage of 0.16 s/188 cm for a sprinter who shaves 500 g off their wheels. If that weight went to make an aero wheel that was worth 0.03 mph (0.05 km/h) at 25 mph (40 km/h), the weight savings would be canceled by the aerodynamic advantage. For reference, the best aero bicycle wheels are worth about 0.4 mph (0.6 km/h) at 25, and so in this sprint would handily beat a set of wheels weighing 500 g less.
In a criterium race, a rider is often jumping out of every corner. If the rider has to brake entering each corner (no coasting to slow down), then the KE that is added in each jump is wasted as heat in braking. For a flat crit at 40 km/h, 1 km circuit, 4 corners per lap, 10 km/h speed loss at each corner, one hour duration, 80 kg rider/6.5 kg bike/1.75 kg rims/tires/spokes, there would be 160 corner jumps. This effort adds 387 kilocalories to the 1100 kilocalories required for the same ride at steady speed. Removing 500 g from the wheels, reduces the total body energy requirement by 4.4 kilocalories. If the extra 500 g in the wheels had resulted in a 0.3% reduction in aerodynamic drag factor (worth a 0.02 mph (0.03 km/h) speed increase at 25 mph), the caloric cost of the added weight effect would be canceled by the reduced work to overcome the wind.
Another place where light wheels are claimed to have great advantage is in climbing. Though one may hear expressions such as "these wheels were worth 1–2 mph", etc. The formula for power suggests that 1 lb saved is worth 0.06 mph (0.1 km/h) on a 7% grade, and even a 4 lb saving is worth only 0.25 mph (0.4 km/h) for a light rider. So, where is the big savings in wheel weight reduction coming from? One argument is that there is no such improvement; that it is "placebo effect". But it has been proposed that the speed variation with each pedal stroke when riding up a hill explains such an advantage. However the energy of speed variation is conserved; during the power phase of pedaling the bike speeds up slightly, which stores KE, and in the "dead spot" at the top of the pedal stroke the bike slows down, which recovers that KE. Thus increased rotating mass may slightly reduce speed variations, but it does not add energy requirement beyond that of the same non-rotating mass.
Lighter bikes are easier to get up hills, but the cost of "rotating mass" is only an issue during a rapid acceleration, and it is small even then.

No big races planned so far but maybe thishttp://transrockies.com/trc/ or thishttp://www.sevenbikerace.com/or thishttp://testofmetal.com/ or my first pick if i could make it down there is thishttp://www.cascadecreampuff.com/ because i think it would be the hardest ( check out the times ).My wife wants to go west this year so if i do anything thing it will be out that way somewhere.Besides that i plan on having fun doing some local races and maybe http://www.offroadsyndicate.com/xc8.php to end off the summer.
