Safety during cold and dark seasons: The spikes guarantee traction, while the reflective stripes ensure visibility. Maintain full control of your bicycle even in turns and hard stops. - Our recommendation for snow and icy roads - Includes 120 spikes SafetySystem Breaker The SafetySystem Breaker is made up of Kevlar-reinforced, high-strength nylon fabric. Puncture- and cut-resistant but nevertheless light and flexible, the tire adjusts quickly to the surface below. Without raising the weight or rolling resistance noticeably, it protects the carcass against foreign objects and contributes to a longer lifespan of the tire. Tires with the SafetySystem Breaker also provide good comfort properties. Suitable for E-Bikes For our E-Bike tires, we relied on over 100 years of experience with moped and motorcycle tires. All of our city/trekking tires are rated to a standard speed of at least 25 km/h. Those tires marked e50 are also certified for S-Pedelecs. With their high-quality structure, puncture protection is high and the rolling resistance is low, offering protection from premature wear brought about by the additional driving force.

IF YOU HAD JUST ONE JACKET The Perfetto RoS is the one jacket that does everything well. We initially designed it as a cool-weather training and extreme-weather race piece for our pro riders, but in reality, it excels in many conditions thanks to its full wind protection, great fit through stretchy fabrics, and best-in-class breathability. Winter 2019 represents the biggest performance upgrade in the four generations of this jacket. RoS in the name signifies Rain or Shine. The emphasis should be on dry-weather comfort, which is where this jacket really excels, but then you get near waterproof protection if you do get caught in the rain. We worked with Gore to develop two new Castelli exclusive GORE-TEX INFINIUM WINDSTOPPER fabrics. We use a light fleece-lined water-resistant version on the forward-facing surfaces and a lighter, stretchier fabric on the back that maintains the breathability of the previous fabric while improving water repellency at the same time. The Perfetto RoS is that ideal weight: no built-in insulation so you can layer over a light base layer for moderate conditions. Or you can add a thermal jersey underneath and take it to very cold conditions. You decide. The Perfetto family features are all there: excellent fit, easy-sliding YKK zipper, long tail to protect from wheel-spray, reflective panel on the back, and discreet styling that belies the jacket's racing pedigree. This is the one jacket that belongs in every cyclist's quiver. - Castelli exclusive GORE-TEX INFINIUM 205 Warm brushed waterproof fabric on front-facing surfaces - GORE-TEX INFINIUM 203 Stretch on rear-facing surfaces for extra stretch and breathability - Taped shoulder seams for extra rain protection - YKK Vislon zipper for easy sliding, covered for extra wind and rain protection - Zippered ventilation opening on side of chest - 2 rear pockets with pump sleeve are easily accessed with gloved hands - Gabba-style dropped tail with large black reflective panel - 4°-14°C / 39°-57°F - Weight: 261g

While pants may be the latest fashion for all the "cool kids", they have some serious function too.

More power, better traction, less shifting. Wolf Tooth oval chainrings use our proprietary PowerTrac design that has all the benefits of oval, but without the funky, uneven pedal stroke. Ride one once and you'll wonder why you waited so long to try oval. Think of an oval chainring as two chainrings in one. A major benefit of oval is how the shape of the chainring alters your gearing in two important phases of your pedal stroke by harnessing your body's natural biomechanics. Here's how it works. The area of the chainring with the larger diameter engages with the chain at the optimal point on the downstroke, which is what's known as the Power Zone. If you were to look at a clock, the Power Zone would be between 1-5 and 7-11. Conversely, the Recovery Zone – back to the clock face, between 11-1 and 5-7 – is the weakest part of the pedal stroke, when the oval maximizes your efficiency. A 34T oval chainring behaves like a 36T chainring when you want power, while behaving like a 32T chainring when you're climbing. We've also engineered our oval chainrings to provide smoother, more efficient pedal rotation. This equates to better traction because of steadier torque on the rear wheel. With a Wolf Tooth oval chainring, you can harness more of your strength in the Power Zone, while having easier pedaling in the Recovery Zone. Compatibility: - These rings fit on the Shimano XT M8000, SLX M7000, Deore M6000, or FC MT5100 1x or 2x cranksets. - Use only the stock Shimano XT M8000 or SLX M7000 chainring bolts - These CAN be mounted to the XTR 9000 series cranks, but you will have to use the bolt caps that come with that crankset and you will need to file roughly 1mm off the threaded boss on each bolt cap (they are a little too long and don't allow the ring to be tightened down) - Wolf Tooth's patented Drop-Stop® wide/narrow tooth profile for the ultimate chain retention and mud shedding ability - If using a 9-speed drivetrain use a 10-speed chain (shifts and works well on a 9-speed drivetrain and fits the ring tighter for better chain retention). - Provide a great chainline on most boost bikes. See this explanation for details. - Drop-Stop A models will reduce the chainline (inward towards the frame) from the Shimano specified chainline for the crankset: 26T-28T = -3mm, 30T-34T = -2mm, and 36T-38T = -1mm - Drop-Stop ST models will have the same chainline as the Shimano specified chainline - Must use the stock chainring bolts. The Wolf Tooth chainring bolts are a different size. - Ovality of 10% and timing of 112° after TDC (top dead center) - Maximum diameter is that of a chainring 2t bigger than the size you order so be sure there is adequate chainstay clearance. - Available in multiple tooth profiles for optimal performance based on your chain type. Use Drop-Stop ST for use with Shimano 12-speed Hyperglide+ and 12spd KMC chains. Use Drop-Stop A for all 9, 10, and 11spd chains or 12spd SRAM Eagle, KMC, Connex or Wippermann chains. Drop-Stop B is optimized for SRAM 12 spd Transmission (T-type) and Road Flattop chains but is compatible with all chains that work with Drop-Stop A. DROP-STOP A - Wolf Tooth Drop-Stop A is the original patented wide/narrow chainring compatible with multiple drivetrain brands including 9, 10, 11, and 12s SRAM Eagle, KMC, Wippermann, etc. - NOT compatible with 12s SRAM Transmission (T-Type) Flattop, 12s Shimano HG+, or 12s Campy DROP-STOP ST - Compatible with 12s Shimano Hyperglide+ chain and 12s KMC chain only - Symmetric Trapezoidal (ST) tooth shape is optimized for Shimano HG+ chain Recommendations - - If you plan to ride in very muddy conditions, we recommend a chainguide or chainkeeper in addition to a clutch-type rear derailleur. Without these precautions, you may experience chaindrops and/or chainsuck. - Recommend the use of a clutch style rear derailleur for the best chain security.
