Shimano will unveil a limited-edition version of its R321 road shoe at the Tour de France.
40 riders from teams including Orica GreenEDGE, Giant-Alpecin, Team Sky, Team LottoNL-Jumbo, IAM and Cannondale-Garmin are already riding with the original R321, introduced last year.
A blue upper surround on the R321B features a dimpled contour with aerodynamic styling. The upper made from Teijin Avail 100 Ultra-fine fibre, which makes the shoes stretch-resistant, extremely durable and lightweight. This material adapts to the foot’s shape during a custom-fit process.
There are also black air vents in the toe cap and exhaust ports.
The R321B sits upon an ultra-rigid, lightweight, hollow channel, black, blue and yellow cross-carbon weave outsole with a 12/12 stiffness rating for maximum power transfer. The sole construction offers 22 mm of adjustment, doubling the standard fore and aft range of the cleat setting
The insole, heel cup and upper incorporate Shimano’s thermo-moldable ‘Custom-Fit’ material.
