SRAM Red 22 BB30 Crankset

The new SRAM Red 22 BB30 Crankset has gone away from that first-generation foam-core formula, and now has a significantly beefier arm shape with a true hollow cross section. Because of the larger carbon-optimizing structure, SRAM is able to use less material, effectively reducing weight without negatively affecting stiffness. This also allowed them to rotate the spider to take advantage of the large, flex-fighting crank arm.

SRAM chose to stick with the 130mm bolt circle diameter standard, ensuring compatibility with aftermarket chainrings, but they've arranged the spider to position a mounting bolt on the backside of the crank arm. By integrating a mounting location within the existing carbon structure, they're able to reduce weight and deflection from shifting -- effectively enhancing the accuracy, speed, and quality of front shifts. This reduces the number of spider arms to four and gives the cranks a sleek, air-splitting profile.

The Red Exogram chainrings have also received extensive reworking to boost front shifting performance, specifically focusing on integration with the rotating, Yaw-caged Red front derailleur. Coined X Glide R, these chainrings are machined from 5mm thick 7075-T6 aluminum and now have been carefully tuned to accommodate the 11-speed drivetrain. SRAM used extensive computer-aided finite element analysis to optimize stiffness first, followed by shift ramp profiles. Then they set out to eliminate any unnecessary material without affecting the structure. SRAM placed the new shift pins to correlate with your cadence and cut the ramps to into a profile that works seamlessly with the new Red front derailleur.

GU Roctane Gel

GU Roctane

Single Packet

Roctane takes athletes' top choice for an energy gel, GU, amplifies the original recipe and then adds new ingredients to boost performance in sustained, high-intensity efforts. Here's how it's done:
  • GU starts with a superior mix of complex and simple carbohydrates that provide quick and sustained energy, electrolytes for replenishment and caffeine to tap more power and diminish pain.
  • From there GU increases the amount of histidine, an essential amino acid, to act as a buffer and slow the energy-sapping lactic acid build-up in muscles.
  • GU mixes in higher levels of citrates (potassium citrate, sodium citrate, and citric acid) to help speed the conversion of carbohydrates into energy molecules and, like histidine, help mitigate acid build-up.
  • GU also adds more of the branched chain amino acids (BCAAs) leucine, valine and isoleucine to serve as another fuel source, aid in recovery and help maintain mental focus and reduce fatigue by limiting the central nervous system's production of serotonin.
  • Finally, GU adds a new ingredient, the amino acid complex Ornithine Alpha-Ketoglutarate (OKG) which limits the body's tendency to break down muscle protein tissue during extremely hard training and racing days. OKG keeps you going longer and promotes a speedier recovery.
Roctane Ultra Endurance Energy Gel packs 100 calories into every packet. It's an ideal serving size to suck down 15 minutes before training or racing in order to top off your electrolyte and glucose stores, followed by one every 30-45 minutes along the way, washed down with a few sips of fluid.
