Tour Proven Stages Power has carried riders to three consecutive Tour de France victories, plus many more world and national championships. If you believe racing provides the world’s best product proving ground, then Stages Power is proven as the world’s best power meter. Active Temperature Compensation as standard equipment Consistency of measurement is the most important feature of a power meter. Stages Power was the first meter to make temperature compensation an automatic process ensuring accurate readings no matter the environmental conditions. ATC is the key reason a rider can trust data from Stages Power in all conditions. Individual meter calibration for the most accurate results Each Stages Power meter is calibrated individually to ensure a +/- 1,5% accuracy level, which is an industry best for non-scientific power meters. Individual calibration means that you can trust the bi-lateral data produced by our system, as it's a real measurement and not an estimation. Stages Power R drive-side meter for added compatibility or upgrading an existing Stages Power L meter to Stages Power LR While not widespread there are some key bicycle models that are not compatibile with the non-drive crank arm based Stages Power meter because of interference with the power meter housing, for example Cervelo's P5 and many bikes with chainstay mounted brake calipers. Stages Power R offers increased compatibility with these models as well as the ability to upgrade existing Stages Power L power meters to Stages Power LR (dual) meter systems. Features: Active temperature compensation Accelerometer based cadence measurement or the option to use a Hall-Effect based system with magnet Wirelessly upgradable firmware LED indicator for visual indication of battery levels and zero reset confirmation without connected app or headunit Updated accelorometer and addition of gyroscope for improved cadence resolution NFC tap to pair for some phones and devices Upgraded BLE and ANT+ radios offer a 6x improvement of data transmission strength Specifications: Accuracy: +/- 1,5% accurate in all conditions Power meter housing: low profile design, with robust door interface. Tool free battery replacement on the left arm and phillips head screw access on the drive side Weight: Only adds 35g (Stages Power LR) / 15g (Stages Power L) / 20g (Stages Power R) to base crank set Battery life: 175+ hours (Stages Power LR, via 2 coin cell: CR2032), 200+ hours (coin cell: CR2032) when used as a single sided Stages Power L or Stages Power R meter Power range (Watts): 0 - 2500 Cadence range (rpm): 20 - 220 Water resistance rating: IPX7 Compatibility: Stages Power L - Compatible with all Shimano Hollowtech II road drive side crank arms.

The Project 23 Carbon Full Face Helmet features a whole host of materials and technologies to ensure your head gets the finest protection possible while offering an incredibly low weight for a hard-shell lid. Seven iDP chose a Carbon Fibre hardshell construction over the EPS foam core rather than in-moulding a light outer to a foam core, as can be found on most trail helmets. This makes it superb at absorbing impacts, prevents penetration from ground objects and, thanks to the carbon outer, weight is kept low without compromising safety. The CRV (Crash Release Visor) is also designed to snap away in the event of a crash, reducing forces on the neck and head. It simply snaps back into place too, rather than using bolts. The Project 23 Carbon also features the S.E.R.T. system, this acts as a slip-plane system to manage the rotational forces on your head and brain. By minimising and managing the transmission of impact forces to your brain, some 20% greater absorption than standard systems, you're less likely to suffer chronic brain injuries. The 23 vents make this the most ventilated hard-shell full-face helmet currently available. The TF (Through Flow) Goggle ventilation ensures you always have a clear view too, keeping fogging at bay. Size guide: X-Small: 20.75" - 21.25" (53 - 54cm) Small: 21.5" - 22" (55 - 56cm) Medium: 22.5" - 22.75" (57 - 58cm) Large: 23.5" - 23.75" (59 - 60cm) X-Large: 24" - 24.25" (61 - 62cm) XX-Large: 24.8" - 25.1" (63 - 64cm)

The most aero road helmet in the peloton now breathes better. The S-Works Evade 3 was reinvented from the inside out to cool better making it the fastest choice for more stages. Through extensive Computational Fluid Dynamics and Win Tunnel testing we created a rear “diffuser” that helps minimize drag and improve ventilation. The diffuser helps optimize aero performance by allowing air to release easier and improves ventilation by drawing 10% more air through the helmet at a given speed. The Occipital Base Adjustment optimizes comfort by personalizing fit to individual head shape and helmet angle can be adjusted for compatibility with glasses. An adjustable Tri-Fix web system gives riders added comfort with updated thinner 10mm webbing that minimizes strap noise. And the ANGi-ready ultralight Mindset micro-dial fit system with height adjustability has been updated for improved grip and reaction for easy on-the-go fit. Our ultralight and supremely comfortable MIPS Node Air technology is integrated directly into the helmet padding with a sleek low friction layer designed to dissipate rotational forces. With Specialized’s proprietary development work we added perforations to maximize breathability performance comfort and weight savings. Enlarged front vents help increase ventilation. Rear Diffuser for aero and ventilation benefits. MIPS Air Node is MIPS’ most ventilation-focused solution. Adjustable Tri-Fix web splitter boosts comfort through personalized fit. Precision full-wrap polycarbonate shell for increased durability and premium finish. Dual-density optimized EPS foam.
The S-Works Prevail 3 helmet is perfect for riders who value the comfort and thermoregulation benefits that superior ventilation delivers. It is the ultimate all-around helmet that excels in hot conditions strenuous climbs and mountainous stages. With a never-ending quest to push the limits of ventilation we eliminated air-blocking foam “bridges” from the center effectively creating thru-air channels that increase the surface area of ventilation by 24.5% compared to the S-Works Prevail II Vent helmet. The all-new S-Works Prevail 3 has the most ventilation area of any helmet we have ever made. When a helmet is impacted its job is to dissipate the energy of the impact. The conventional approach to helmet design is that more foam (EPS) means better energy management. We re-wrote the book on cycling helmet design by innovating beyond foam. Woven aramid “cables” traverse the helmet and are anchored to carbon fiber side panels. Upon impact the AirCage technology* works as a suspension bridge and is designed to distribute localized forces throughout the helmet.
