DT Swiss XMM Fork




            Suspension-wise, Swiss manufacturer DT is probably best known for their super fancy carbon-clad suspension forks, but they’ve now launched a more affordable line. Rather than carbon, the lower legs are formed from magnesium – like many other brands. The main difference with the DT design can be seen in the unique arch that links the sliders; it is made using two cast magnesium parts that bond together to form a single hollow bridge. Called ‘Torsion Box’, it is said to be substantially stiffer than a traditional solid arch with no weight penalty. The XMM should weigh around 1,650g in the 9mm QR version and 1,745g with a 15mm thru-axle, and the one platform converts to either 100, 120 or 140mm travel options. DT’s ‘Twin Shot’ dampers offers three externally controlled options; fully open, a reduced travel mode for climbing and a full lockout. Expect to pay around $1,070.

American Classic Road Tubeless Wheels



            For 2012 American Classic has added another option to the growing number of tubeless compatible clincher wheels. While they still have spoke holes on the inner rim and need tape to make them airtight, they feature a special inner rim profile with a lip to securely hold the tyre bead once inflated. Interestingly, American Classic has opted for a wider than normal 22mm rim profile with lower bead hooks. This allows the tyre carcass to spread out further, effectively making it wider than it would be if mounted to a traditional rim. The idea is that you can use them with a narrower tyre to save weight without compromising the contact patch and cornering grip. Speaking of weight, the American Classic Tubeless wheels are extremely light, coming in at 1,179g  for the pair. Pricing should be around the $1,100 mark.
