Former Giro d'Italia winner Denis Menchov returns to his Russian roots for the 2012 season after just a single year with the ill-fated Geox-TMC squad. His move to Katusha means he'll be competing on bikes from German company Canyon instead of his previous Fujis.
Menchov will likely have any number of Canyon's road and time trial bikes at his disposal this year but for now, his primary machine is the Aeroad CF – the same chassis that Philippe Gilbert (Omega Pharma-Lotto) rode to huge successes last season.
Canyon didn't design the Aeroad in the wind tunnel, instead focusing on building the frame with nominally aero tube profiles and minimizing frontal area. As compared to the company's more traditional Ultimate CF SLX, the Aeroad isn't as stiff either in torsion or at the drivetrain – particularly with the downsized 1-1/8 to 1-1/4in steerer instead of Canyon's usual OneOneFour fork – but it's still up to the task and clearly didn't seem to slow Gilbert down.
Frame weight is a touch heavier than the Ultimate CF SLX at just over 1,000g for Menchov's medium size – not an especially impressive number as compared to true lightweights but given the realities of the UCI's minimum weight rule, Katusha will still have no problem keeping Menchov's new bike right at that mark. Even with an SRM power meter, an SRM PowerControl 7 computer head, Elite bottle cages and Mavic Cosmic Carbone SLR training clinchers installed, weight is just 7.19kg (15.85lb), according to team officials.
Other key components include a Shimano Dura-Ace Di2 group and carbon bodied pedals, a Ritchey WCS aluminum semi-anatomic bar and forged aluminum stem, a Selle Italia Flite Team Edition saddle, an Acros integrated headset, and Canyon's own shock-absorbing VCLS carbon and
basalt fiber aero-profile seatpost.
Menchov's biggest result came in 2009 when he won the Giro d'Italia but subsequent years have been less satisfying – he wasn't even able to contend last year's Tour de France as Geox-TMC didn't receive a wild card invitation. The Russian has publicly declared the Tour to be his main objective this year, however, so we can expect to see more of this Aeroad – along with Canyon's new time trial bike – later this season.
Carbon fiber in civil engineering applications
Carbon fiber reinforced polymer- has over the past two decades become an increasingly notable material used in structural engineering applications. Studied in an academic context as to its potential benefits in construction, it has also proved itself cost-effective in a number of field applications strengthening concrete, masonry, steel, cast iron, and timber structures. Its use in industry can be either for retrofitting to strengthen an existing structure or as an alternative reinforcing (or prestressing material) instead of steel from the outset of a project.
Fiberglass hand lay-up operation
Resin is mixed with a catalyst or hardener if working with epoxy, otherwise it will not cure (harden) for days/weeks. Next, the mold is wetted out with the mixture. The sheets of fiberglass are placed over the mold and rolled down into the mold using steel rollers. The material must be securely attached to the mold, air must not be trapped in between the
fiberglass and the mold. Additional resin is applied and possibly additional sheets of fiberglass. Rollers are used to make sure the resin is between all the layers, the glass is wetted throughout the entire thickness of the laminate, and any air pockets are removed. The work must be done quickly enough to complete the job before the resin starts to cure. Various curing times can be achieved by altering the amount of catalyst employed. It is important to use the correct ratio of catalyst to resin to ensure the correct curing time. 1% catalyst is a slow cure, 2% is the recommended ratio, and 3% will give a fast cure. Adding more than 4% may result in the resin failing to cure at all.[6] To finish the process, a weight is applied from the top to press out any excess resin and trapped air. Stops (like coins) are used to maintain the thickness which the weight could otherwise compress beyond the desired limit.
