SmartGuard The most efficient protection belt there is for bike tyres, in other words: flatless. Solid, 5 mm thick layer of highly flexible special rubber provides permanent protection also in the case of embedded objects. Even thumbtacks are no problem for this tyre. Improved Rolling resistance The patented, 5 mm thick SmartGuard layer, when compared to all generic products, has a significant advantage in rolling resistance. We further extended its lead in the latest version. Also in the SmartGuard, we now use a proportion of recycled rubber from old latex products. "Anti-aging" side wall It now lasts much longer before developing unsightly cracks when subjected to use with too low air pressure. Tyre ETRTO: 26x2.1”: 54-559 27.5x2.1”: 54-584 29x2.1”: 54-622
Kevlar®Guard We have improved the well known Kevlar belt. This protective layer is stronger and safer but at the same time more flexible. This result in the protection level being higher and rolling resistance lower
This tyres features: GreenGuard. The highly elastic, India rubber layer is 3mm thick. Other manufacturers call such a tyre "Plus". However, Green is not just the colour, but also the philosophy: One third of the GreenGuard is made up of recycled latex products. "Anti-Ageing". The completely new sidewall construction can withstand for much longer the typical cracking resulting from overloading due to insufficient inflation pressure. Also the new Endurance Compound substantially increases durability. E-Bike Ready. The new Marathon has been designed for use on all types of E-Bikes. The following sizes bear the ECE75 mark, suitable for the use on faster, up to 50kph E-Bikes.
The spikes work best on ice when running at minimum pressure, while at maximum pressure the tyres can be ridden on ice-free roads with minimal road noise. Spikes F&Q's Can it also be ridden on a normal road? Without any problem, but if the road is only rarely covered with snow the resulting tyre noise may prove annoying. And it won't slide out in cornering? No. The spikes 'claw' really well into normal asphalt roads and even fast cornering is not a problem. Aren't spikes illegal? Bike tyre spikes are no problem. Only motor vehicles spikes are prohibited in some countries, because they damage the road. Fast E-bikes are however considered motor vehicles. Do the tyres have to be run in? In order to ensure that spikes are permanently fixed, tyres should be run in for about 25 miles on asphalt, while avoiding any fast acceleration or heavy braking. What is the lifespan of the spikes? All Schwalbe spikes have a core made of extremely hard wearing tungsten carbide, so they can cover a few thousand miles. It is normal for the spike edges to round off and for them to become more deeply embedded.
The spikes work best on ice when running at minimum pressure, while at maximum pressure the tyres can be ridden on ice-free roads with minimal road noise. In order to ensure that spikes are permanently fixed, tyres should be run in for about 40km on asphalt, while avoiding any fast acceleration or heavy braking. SMARTGUARD FLAT-LESS The safest puncture belt for bicycle tyres. Unbeatable for more than 15 years. It has proved itself in practice more than any other tyre. Only tyres with SmartGuard are real flat-less tyres. Spikes F&Q's Can it also be ridden on a normal road?

During these 100 years Columbus has increased its knowledge to correctly define every functional aspect of a fork, thoroughly calculating the optimum side and frontal strength parameters, without omitting the aesthetic aspect and lightness of the piece. Since more than 90 years the forks made with Columbus steel fork blades are all of this. Today the use of carbon fibre gives more lightness to this component and allows Columbus to capitalise its experience. Carbon fibre is 4 times more resistant than steel and 8 times more resistant than alloy, and thanks to its versatility and sense of direction of the fibres.
Optimised for use with caliper brakes, the Futura features a tapered steerer for enhanced control as you weave around your chosen route. Durably built to cope with all weather conditions, it is equipped with asymmetrically reinforced areas and enhanced torsion control to make sure no ride is too intimidating for you or your bike. An excellent addition to any modern road bike, the Futura is a top performing fork for the fast and focused rider.
Made from aeronautical grade muti-layer carbon fibre - The progressive curve of the blades dampens vibrations and gives great stability in extreme conditions.
If Leonard Smalls were to trade out his beefed-up Honda VT500 and pedal his way across the Arizona desert we have no doubt it’d be aboard the Unit. Burly. Steel. Hardcore. Mean. Mean? Sure. The Unit does not mess around. Its single-speed design and Cromoly frame make its simplicity shine and keep the moving parts long-lasting for those big excursions. Gear mounts on the fork legs and several options for mounting water bottles mean you won’t go without any of the necessary gear no matter where you’re traveling. FEATURES REYNOLDS 520 CROMOLY Reynolds 520 tubes are mandrel-butted for accurate profiles and available in a wide range of shapes. Weight savings from butting provides competitively priced light framesets that are noticeably compliant on the road or the trail and are guaranteed to last a lifetime. INTERNAL HEADSET Bearing cups are actually pressed into the frame and are easily removable. An internal headset also reduces stack height so the height of the stem and bars are more adjustable giving the rider the best fit possible. 44mm HEAD TUBE 44mm oversized heatubes allow us to run tapered steerer forks by using a large external lower cup headset bearing. The larger diameter steerer tube adds considerable stiffness and will increase responsiveness to the front end improving all-around performance. TUBELESS COMPATIBLE RIMS Tubeless rims allow for tires with more puncture resistance; the ability to run lower tire pressure which provides better tire grip on the trail; lower rolling resistance; and weight savings over traditional tube and tire systems. 12x148mm AXLE 12x142mm 12x148 and 12x157 rear axle standards provide two major advantages to the Kona rider: the 12mm diameter of the rear axle provides the rear hub and frame with a stiff interface while the 142/148/157mm outer diameter of the hub allows the wheel to be quickly and properly positioned in the frame before the rear axle is inserted. For 2017 you’ll see the 12x148 Boost standard in the mix. Boost spacing provides more tire clearance at the chainstay yoke while the rear wheel is stiffer and more durable relative to a 12x142 thru-axle.
