Shimnao SH-R321 Shoes

The new Shimano SH-R21 road shoe retails for $380.

Shimano has launched its newest top-end road race cycling shoe, the SH-R321. The new kicks pick up where the SH-R320 shoe left off, utilizing a second generation of Shimano's Dynalast construction. The upper incorporates new materials and additional custom fit features to provide better fit, extra comfort and increased pedaling efficiency, says Shimano.

The shoe comes in white only. Sizes run 38-47 with half sizes, plus a 48. E-width is also available. Claimed weight is 489 grams for a size 40. Availability is set for winter 2015 with an MSRP of $380.

The upper wraps around the foot in a way that is more secure and comfortable than previous designs. New arch and upper instep sections incorporate heat-moldable, custom-fit film that improves comfort and gives the foot added support. The arch-supporting material, in combination with Shimano's custom fit insoles, promotes a more stable pedaling platform that keeps the rider's feet in position throughout the pedal stroke.

These new kicks are claimed to enhance comfort, fit and efficiency while reducing weight.

The new shoe's upper uses Teijin Avail 100 Ultra fine-fiber material, rather than standard synthetic leather, for better stretch resistance, improved durability and light weigh. New buckles are adjustable to various instep heights and shapes thanks to the dual strap mounts that pivot for better strap/buckle alignment. The flat surface concept with reversed low-profile buckles and straps gives the SH-R321 a very smooth and aerodynamic styling.

The external heel cup supports the heel and stabilizes pedaling by holding the heel snugly in place, while a new anti-slip heel lining also prevents unwanted heel lift. The rigid, lightweight hollow channel outsole has Shimano's unique Dynalast shape and features a 12/12 stiffness rating. The sole construction also offers an extra 11 mm of fore/aft adjustment range to help you find the ideal shoe-to-pedal fit.

New Alloy TT Bar

Also just launched by Shimano component brand PRO is a new alloy version of the PRO Missile EVO handlebar. Highlight features of the PRO Missile Alloy triathlon handlebar include light weight, adjustability, comfort and price. MSRP for the base bar along is $100.

The Missile Alloy's adjustability is fostered by stackable 5mm spacers available to create the right setup for individual riders. To keep weight in check, PRO used Al6066 aluminum and hydro formed its Missile Alloy base bar to achieve a total weight of 729 grams (sans spacers).

The hydroformed base bar cross section is within the UCI's required 3:1 ratio, and the Missile Alloy has soft arm-pads for more comfort. Both the base bar and clip-ons offer internal cable routing for Di2 and mechanical shifting. The base bar is 40cm wide and has a 3.5cm drop with tip up bar ends to give extra grip.

Ski-bend extensions are $200, measure 344mm with cut lines and weigh 482 grams. S-bend extensions, which are more aero and are designed for more aggressive riding, will also retail for $200, are 347mm long with cut lines, and weigh 474 grams.
