Industry Nine (I9) is following the introduction of its new mountain bike Trail 270 wheelset with a new line of sectional carbon road wheels that it hopes will make the premium brand a more significant option for road cyclists. The 24-hole, disc-brake wheels come in three depths: 35mm, 45mm, and 65mm. The rims all have a 21mm inner width and are tubeless ready. As with I9’s mountain wheels, you can select the hub and spoke nipple colors to match your bike and even customize the graphics. Because I9’s wheels are built to order, the rims can be mixed if you want a different depth for the front and rear rims.

The team at I9 says they have been working on the design of the wheels for over two years at the brand's Asheville, North Carolina, headquarters. The three rim shapes were designed in house by I9, and are manufactured by Reynolds. The new rims have relatively wide inner widths and a more compliant construction to deliver what the company hopes is the best ride possible with wider tires. In wind tunnel tests, the company claims the wheels performed competitively to Zipp’s 303 and 404 wheels in aerodynamics and cross-wind handling.
Based on the success of its I9’s mountain bike wheels, the brand could become a strong option for riders seeking high-performance aerodynamic road wheels. We have some of the new hoops and will publish an in-depth review soon.

Chris Froome has been nominated for the prestigious 2018 Laureus World Sportsman of the Year award. The organisation collected the nominations through a ballot by members of international sports media. The full list of nominees was announced on Tuesday. The winners, as voted for by members of the Laureus World Sports Academy, will be revealed in Monaco on February 27, according to the organisation’s website. The Laureus World Sports Awards is an annual award ceremony honouring individuals and teams from the world of sports along with sporting achievements throughout the year. The awards support the work of Laureus Sport for Good, international projects that use the power of sport to end violence, discrimination and disadvantage, proving sports has the power to change the world.ADVERTISEMENT Froome is up for the Laureus World Sportsman of the Year for winning his fourth Tour de France title in 2017. He joins a list of other high-profile athletes nominated for the award including soccer player Cristiano Ronaldo, distance runner Mo Farah, Formula One world champion Lewis Hamilton and French and US Open champion Rafael Nadal. In September, Froome returned an adverse analytical finding (AAF) at the Vuelta a España for twice the permissible dose of the asthma medication salbutamol. The test took place September 7 following stage 18 of the Vuelta, a race which Froome went on to win overall. He was notified of the failed test after winning the bronze medal in the individual time trial at the UCI Road World Championships in Bergen on September 20. He has denied exceeding the permitted dosage of his asthma drug. Salbutamol is a 'specified' substance on the World Anti-Doping Agency prohibited list and so Froome was not provisionally suspended. To avoid a suspension, Froome and his legal team must convince the anti-doping authorities that he did not exceed permitted dosage and that his sample was skewed by other factors such as dehydration.

UCI president David Lappartient has said that he hopes that the investigation into Chris Froome's salbutamol adverse analytical finding will be resolved ahead of the Giro d’Italia. Lappartient mirrors the wishes of Giro race director Mauro Vegni, who yesterday made a plea to the UCI to "sort out" the case, but emphasized that it is important to protect the rights of riders. Froome is scheduled to ride the race in May as he attempts a Giro-Tour double. If the investigation does not reach its conclusion before the Giro d'Italia, Froome would still be able to race. Should he win, the result could later be disqualified if Froome was retroactively banned, as in the case of Alberto Contador in 2011. “I hope so,” Lappartient told Swiss publication Neue Zurcher Zeitung when asked if the case would be resolved by the Italian Grand Tour. “The case is very bad for cycling. He is the most famous rider we have.”ADVERTISEMENT Lappartient added that Froome had not been given any special treatment by being allowed to continue to compete while the case is ongoing, saying that forcing Froome to suspend himself would go against their own regulations. Although, he added that it would have made things easier if Team Sky were part of the MPCC, which requires teams to suspend any riders under investigation. "It is important to uphold the rights of the rider," Lappartient said. "There is no special treatment for him, even if some riders claim that. Salbutamol is one of the drugs allowed in a limited dose. An immediate suspension would conflict with the rules in force. "It would also be good if Sky were MPCC members. Then Froome would have suspended himself. But that's up to the teams." Motor doping, team radios and Lance Armstrong

Stijn Vandenbergh hasn’t competed in a Grand Tour since 2010 and he’s only ever finished one three-week race in his entire career, but the 33-year-old Classics specialist is in contention for a place on Romain Bardet’s Tour de France team. Why, when teams are being cut from nine riders to eight, would AG2R la Mondiale consider giving a place to a rider who has never made stage racing his forte? The answer lies in the profile of the first week of the Tour de France and Vandenbergh's relatively unique skill set in a team more suited to stage racing in the mountains. The opening days of the Tour – until the first rest-day – are littered with danger, especially for a lightweight like Bardet. Cobbles, tight roads, fights for position and a team trial – Bardet could potentially be minutes down before the race even reaches the mountains. Step forward Vandenbergh.ADVERTISEMENT "Something like the Tour depends on the condition but I don’t know yet if I’ll do it. It’s been a long time. The last time was when I was at Katusha and I did the Tour de France two times. I finished it once. That’s been seven years ago now," he told Cyclingnews at the Tour Down Under. Almost two meters in height, Vandenbergh was for five years one of Tom Boonen's protectors at Quick-Step. What was good enough for one of the best one-day riders in history would surely serve a rider like Bardet during the chaos of the first week at the Tour. One issue, perhaps is that Vandenbergh track record in three-week racing is virtually non-existent. Two starts, one finish does not scream consistency.

Gianni Bugno has defended Chris Froome’s decision to continue racing while trying to explain his Adverse Analytical Finding (AAF) for salbutamol, insisting the Team Sky leader is innocent until proven guilty. Bugno, double world champion in 1991 and 1992 and now the president of the Cyclistes Professionnels Associés (CPA) riders association, told La Gazzetta dello Sport that he is “on Froome’s side”, but called for a rapid verdict in the case. Twice the permitted level of salbutamol was found in Froome’s urine after stage 18 of the Vuelta a España as Froome fought to defend the leader’s red jersey. The 32-year-old denies exceeding the permitted dosage of his asthma drugs. Given that salbutamol is a ‘specified’ substance on WADA’s prohibited list, Froome has not been suspended by the UCI, but the onus is now on the British rider to convince the authorities his sample could have been skewed by other factors. On Tuesday L’Equipe suggested that Froome’s defence could be based on an unusual accumulation and then release of the drug via his kidneys. However, Froome and Team Sky have not revealed any details of their defence or spoken about the case since initial statements in December. It is understood that Froome and his legal team are still responding to questions from the UCI, with an eventual disciplinary hearing and verdict some time away. Froome has continued to train for the 2018 season since The Guardian and Le Monde exposed the on-going case on December 13, with the Giro d’Italia and Tour de France remaining as major goals. He could possibly make his season debut at an early-season stage race in Europe in February as he builds up to the May 4 start of the Giro. Riders often suspend themselves while caught up in a doping case, or are suspended by their team due to internal rules or those of the Mouvement Pour un Cyclisme Credible (MPCC). Team Sky is not a member of the MPCC. The World Anti-Doping rules allow time away from racing under a self-suspension to be included in any eventual ban. However, Froome seems determined to race as he fights to clear his name, convinced he has not done anything wrong.ADVERTISEMENT Bugno agrees with his position. "I’m totally on his side. Froome is innocent until proven guilty and so it’s right he can race," Bugno told La Gazzetta dello Sport. "If he can’t manage to prove his innocence he’ll pay the consequences. That’s the way it is for everyone, not only him. The important thing is that sporting justice quickly decides things."
