Shimano S-PHYRE RC902 Road Shoes

Shimano S-PHYRE RC902

These blue beauties recently dropped at PEZ Babylon on the Potomac. Shimano’s latest and greatest road shoe. A full review is forthcoming, but we thought we’d give you a taste to whet your appetite.

    ● 360º surround wrapping upper creates a supremely engineered fit for all riders.
    ● Heel cup with anti-twist stabilization secures optimal foot positioning for intense acceleration and high tempo cadences.
    ● Function-specific zones and scientifically optimized upper materials maximize fit and pedaling performance.
    ● Dual low-profile BOA® Li2 dials allow quick and precise micro-adjustments.
    ● Integrated seamless midsole and upper construction set a new level of fit, stability and lightweight performance.
    ● Adjustable powerzone lace guide securely holds forefoot.
    ● Sizes – Standard: 36, 37-47 in half sizes, 48; Wide: 36, 37-47 in half sizes, 48
    ● Colors – Black, Blue, White, Red.

The S-PHYRE RC902 literally takes fitting to another dimension with its new 360° surround wrapping upper, function specific zones, anti-twist stabilizer and refined DYNALAST profile. Its supremely engineered fit minimizes energy loss and maximizes power transfer for pro-grade performance that feels and functions unlike anything you’ve ever worn before.


A first for a SHIMANO shoe, our new 360° surrounding upper wraps the foot in a supportive cocoon from the upper all the way around the outsole. We overcame many material and engineering hurdles to create this revolutionary structure that creates a supremely engineered fit, unparalleled stability and lightweight performance for all riders.

Shimano S-PHYRE RC902

Reinforced mesh and Microfiber leather upper materials are arranged and layered in targeted performance zones to maximize fit, flexibility, rigidity and breathability. It took equal parts science and art to complete this engineering puzzle.

Anti-twist stabilizer is built to handle the intense twisting forces caused by explosive acceleration. We used foot movement studies and pedaling visualizations to redesign the shoe’s structure to support more aggressive acceleration.

When you are striving to create the best possible cycling shoe, every degree and mm matters. New rounds of rider feedback helped us resculpt the last shape for a more comfortable forefoot fit.

Five Ten Freerider Primeblue Shoes ($100)


Five Ten’s Freerider helped to ignite the “flat pedal” revolution. As we are stepping up to the sustainability revolution, it is only fitting that the Freerider is now offered with a Primeblue upper which features Parley Ocean Plastic. Parley Ocean Plastic is made from recycled plastic that’s intercepted from beaches and coastal communities before it can pollute the ocean. The durable upper has a canvas-like feel, with excellent breathability. The mid-flex midsole has medium flex for the perfect balance of pedal feel and power output. It is the ideal shoe for days when you are bike commuting or dashing from school to the bike park and want to wear a single pair of shoes. A rubber cup sole adds durability. Stealth S1 dotty rubber provides unbeatable grip, on and off the pedals.

Five Ten Freerider Pro Primeblue Shoes ($150)

five ten

Five Ten’s Freerider Pro is the ultimate flat-pedal shoe for long days of singletrack. It’s hard to imagine improving the cult classic, but Five Ten did just that by creating a new upper out of Primeblue, adidas’ proprietary material that’s made with Parley Ocean Plastic. The light, durable material contains recycled plastic that’s been recovered from ocean beaches. The shoe is a win-win: high performance, great fit, Stealth S1 Dotty soles, and part of the solution to end plastic waste. The upper has a canvas-like quality and breathes really well. The synthetic upper is weather friendly (meaning it’s easy to wipe off dirt), and there’s an impact-resistant Poron toe cap for added protection.

GU Energy Labs Launches New Energy Drink Mix Flavor
New Caffeine-Free Strawberry Hibiscus ROCTANE Energy Drink Mix delivers refreshing fuel for endurance efforts.


GU Energy Labs today launched the new caffeine-free Strawberry Hibiscus flavor into its ROCTANE Energy Drink Mix line-up, giving athletes an even broader variety of fueling choices. The all-new flavor provides inspiration to keep pushing during tough training blocks and races.

Through extensive testing and their own experience as endurance athletes, the R&D Team at GU knows that avoiding flavor-fatigue is just as important as avoiding physical fatigue. Using Flavor Science as a guide, the team develops exciting yet familiar flavors that evoke memories of favorite foods and drinks, helping athletes stay motivated to continue fueling. With the addition of Strawberry Hibiscus, the ROCTANE Energy Drink line-up now includes five flavors containing critical carbohydrates, electrolytes, and amino acids.

“Consuming only one type of food or drink for many hours while training or racing can lead to flavor fatigue or worse, a loss of appetite and decreased desire to fuel,” said Magda Boulet, GU’s SVP Innovation, Research & Development. “By mixing different flavors and form factors, including liquids and solids, you stand a better chance of maintaining your desire to fuel and keep moving. We believe that the Strawberry Hibiscus ROCTANE Drink is another great option for athletes to add variety to their fueling plans.”

Hibiscus has seen a huge spike in popularity in recent years and was named “Flavor of the Year” in 2019 by Firmenich, the world’s largest flavor developer. Its slightly tart, herbaceous flavor is a natural match for sweet, juicy strawberries, creating a refreshing taste profile with a lively zing.

Strawberry Hibiscus is the fifth flavor in the ROCTANE Energy Drink Mix line and the second non-caffeinated option (joining Grape). As with the other four flavors, (Lemon Berry, Summit Tea, Tropical Fruit and Grape), Strawberry Hibiscus is available in a 12-Serv. Canister (MSRP $30), 24-Serv. Canister (MSRP $45) and a Box of 10 Individual-Serv. Packets (MSRP $32.50). Available for purchase on:


This new flavor expands the comprehensive ROCTANE System, which features products created to fuel any athlete’s most demanding activities and races and promote proper recovery afterward. The full ROCTANE System includes: ROCTANE Energy Drink Mix, ROCTANE Gel, ROCTANE Protein Recovery Drink Mix and the four-supplement ROCTANE Capsules line.
