Bringing the WattShop coloured dazzle to the incredibly popular 3:Sixteen calf sleeves. Available only through WattShop these calf sleeves utilise the same technology as the Aero-bridge baselayer.

Developed at Silverstone Sports Engineering Hub and Derby Velodrome alongside the World's greatest engineers and riders.

The calf sleeves were first introduced to the sporting world during the Sub7 and Sub8 challenges, with the design and name 3:Sixteen a nod towards the 3-hour 16-minute bike leg that was achieved to help guide Joe Skipper to a sub 7-hour Ironman. The team comprised of some of the World's best time-trialists, including Alex Dowsett and the former UCI Hour Record and current British Hour Record holder Dan Bigham, who crushed the opposing team to deliver one of the most incredible time trials of all time.
