Since 1917 all Silca pumps have used steam pressure-formed leather cup washers to achieve high pressures. The 731 (formally 73.1) is the classic 28mm diameter washer used on pumps produced between 1917 and 2008. In 2008, Pista and SuperPista pumps moved from steel barrels with 28mm inner diameter, to aluminium barrels with 30mm diameter. The 741 (formally 74.1) Leather Washer fits all 2008 and later pumps with 30mm inner diameter.Since the 1960's all SILCA leather washers have come from the same leather converting house in the fashion district of Milan, Italy. For more than 5 decades the same supplier has cut these washers from the excess material left over from the production of exotic handbags, Italian luxury cars interiors, and high-fashion luggage. A small press is used to hand cut and then pressure form these washers from pieces of leather otherwise sent to the trash. Silca receives these parts by the hundred and it is always fun to sift through them looking at the various finishes and textures while thinking about the exotic sports car interior, $2000 briefcase, or handcrafted luggage sets from which they share history.From a purely functional standpoint, inexpensive o-rings are most commonly used in this application, but no o-ring can match the smooth feel and zero-stiction action of a leather gasket. It is common today to find Silca leather gasket pumps throughout the professional peloton (especially during the spring classics) as o-ring seal pumps struggle with heat and often are unable to seal once the pump barrel is hot from inflating more than a few wheels.Key Features731 Fits 28mm internal diameter Pista and Super Pista pumps (pre-2008),741 Fits 30mm internal diameter Pista and Super Pista pumps (post-2008),Made from finest quality full grain leather,Produced by hand on the same equipment continuously since 1960,NEW!

In a 2014 interview, Josh told slowtwitch.com that latex inner tubes were the biggest bang for the buck upgrade a cyclist could make. For many years, latex inner tubes were limited to tubular tires, where they are largely responsible for both the puncture resistance and ride quality of the finest tubular tires.Now, Silca has partnered with Vittoria, to create the highest quality, lowest rolling resistance, finest riding inner tube, sized for modern clincher tire setups.Why latex? compared to standard bicycle inner tubes which are made of butyl rubber, latex is significantly more elastic (10x elongation compared to 2-3x), but more importantly, latex rubber has significantly lower coefficient of damping which means that when latex rubber is stretched or flexed, it returns to shape faster and with fewer energy losses.What does this mean for an inner tube? latex inner tubes are generally 2-5 watts (per tire) more efficient at 30mph than tubes made of other materials, are harder to pinch-flat, and offer superior suppleness and road feel, especially when combined with supple, low rolling resistance tires.This tube has been sized to fit tires measuring 24-30mm, which will equate to 23-28mm tires used on modern wider rims. valve stem length is 42mm and will work in all modern disc wheels.

Silca Ultimate Tubeless Sealant combines the power of carbon fibre with a long lasting natural latex formula to achieve sealing properties beyond that of special race day formulas, while matching or exceeding the life expectancy of long-lasting formulas.The key is a high percentage fill of recycled, chopped carbon fibre strands which are held in suspension by the foaming action of the sealant within the tire. Upon puncture, the sealant rushes to escape the hole, carrying thousands of carbon filaments which serve to dam up the opening, just like sticks of a beaver dam blocking a stream. This dam of fibre collects more fibre and what was one large hole, is now turned into hundreds of smaller holes for the sealant to seal. Fiberfoam technology has proven to seal up to 7.5mm holes and cuts at gravel pressures and up to 5mm holes at higher road pressures. Even better, the carbon fibre/latex plug formed at the puncture has proven to be more than twice as strong over time as latex only or latex with crystals or glitter. While most sealants claim they can plug holes up to 6+mm, they can also be injected into the tyre through the 3mm hole in your valve stem with some injectors using tips as small as 2mm. The power of carbon fibre makes this impossible, Silca Ultimate Tubeless Sealant will instantly plug your injection syringe or your valve as the fibres stack up to block the opening. In solving this issue, the Silca team has developed Ultimate Tubeless Sealant into a system that will save you time and money in the long run. The initial installation of Silca Ultimate Tubeless Sealant must be done by pouring into the tyre cavity rather than injecting through the valve. However, unlike other sealants which must be completely replaced every 3-6 months, Silca Ultimate Tubeless Sealant has a special Replenisher which can be pumped through the valve and can extend the sealant life to well over 1 year depending on your climate. This means less wasted sealant, and less hassle over time as there is no need to remove the old sealant at each service interval, in many cases, the sealant may outlast the tyre.
The Ypsilon (pronounced ip.si.lon) is SILCA’s take on the unassuming Y-wrench. Pro mechanics, bike shops, and avid home mechanics have long preferred the layout of this tool due to the ergonomic benefits that make it more convenient and more enjoyable to use. Most tools in this layout feature 4mm, 5mm and 6mm keys; meaning that the wrenches for some of the most common use cases in cycling are readily available in one tool. The shape of the Y-wrench also offers superior control and stability over traditional hex keys, especially in tighter work spaces.Like everything SILCA do, the Ypsilon was designed by a team of engineers and mechanics who obsess over every fine detail. Unlike traditional Y-wrench designs, Ypsilon is customizable and adaptable to the mechanic’s preferences. SILCA were able to do this by using a ¼” bit collet with magnetic attachment in place of one of the 6mm hex wrench. This departure from the traditional Y-wrench design was inspired by the versatility of the T-Ratchet + Ti Torque kit, and means that Ypsilon can easily transform into any tool you need simply by swapping out the bit. The other two ends of the tool are 4mm and 5mm hex keys.Another key benefit of Ypsilon is the tight tolerances of the keys and bits. Tighter tolerances mean a better tool fit which drastically decreases the likelihood of rounding out fastener heads. These tight tolerances, combined with the CrV steel spine of the tool make Ypsilon incredibly durable. A lightweight composite body with ergonomic grips provides good comfort and control with the contact points of your hand.The Ypsilon Wrench is a workshop grade Y wrench with a quarter inch drive it is the perfect addition to your toolkit if you already own quality 1/4 drive hex and Torx bits.Key Features:High strength CrV steel spine leading to 4mm and 5mm Hex,Lightweight composite body with ergonomic grips,¼” bit collet with magnetic attachment.

Silca Super Secret Chain Lube Bottle (4oz)The Super Secret Chain Lube from Silca is a performance-enhancing chain lube that ensures your chain and drivetrain is as smooth and as efficient as can be. Taking inspiration from hot-wax chain dripping lube and is formulated to be environmentally, this chain lube is hard wearing, suitable to all weather conditions and resists the build-up of dirt and grime.Fast and Smooth Performing DrivetrainAll the benefits, none of the hassle. The Silca Super Secret Chain Lube combines the speed and silent running of a hot-melt wax-dipper chain to a drip applied wax lubricant. The Secret Chain Lube also utilises the world's fastest, most lubricious additive, nano-scale Tungsten Disulfide for maximum drive chain performance. Hot Wax Lube Benefits in a Drip Applied LubricantThe Super Secret Chain Lube started as a project to develop the fastest hot-melt wax lubricant in early 2019. Josh Poertner, CEO of Silca, has been recommending hot melt wax and helping pro cyclists and triathletes wax chains for years and he wanted to bring the performance advantages to Silca customers too. The project took a major turn from the world of IndyCar when Poertner was introduced to a group who had developed a technology to put micro-scale wax powders into quick-drying solutions that form a coating that is indiscernible from hot melt dipping in crockpots. The combination of air-drying liquid wax and Tungsten Disulfide quickly proved to beat all currently available hot melt waxes in friction testing while being much faster to apply. The nanoplatelets of WS2 (Tungsten Disulfide) in the Super Secret Chain lube has less than 1/3 the dynamic coefficient friction of PTFE and ¼ that of Molybdenum Disulfide (MoS2). The lube formula is also environmentally friendly, utilising 4 different types of wax and mild alcohol to act as a carrier. Features: Low friction lube that brings the same advantages as hot-melt wax-dipped chains with the convenience of drip applied lubricants Highly lubricious Tungsten Disulfide additive Environmentally friendly formula The chain should be very clean before application Leave chain to dry for at least 30 minutes before ridingBuy Silca Workshop from Chain Reaction Cycles, the World's Largest Online Bike Store.

Ultra-premium levers optimized for carbon rimsModern carbon rims and tires create a real challenge for traditional tire levers, and the new wave of tubeless setups have take the challenge to the next level. Tire fits are tighter than they've ever been, while carbon rims require non-metal levers to resist damage to the bead or brake surface during use.Previous solutions to this problem have involved using a metal core inside of a plastic lever, however this solution has its own challenges as the core of the lever is where you can add the least stiffness and strength. This leaves metal core levers both less stiff and heavier than they need to be.Tire levers premio, pair a high strength forged aluminium lever with a semi-rigid nylon pad on the rim side of the lever only. This allows the overall lever to be thinner, yet stiffer and stronger than either full plastic or metal core designs. Even better, tire levers premio utilize a designed in flex-core zone which allows the nylon pad to conform to the curvature of the rim during use for maximum distribution of load.Due to the high strength full-metal blade, tire levers premio are 25-30% narrower than other lever designs, making them ideal for very tight tires and tubeless setups where access to the tire bead is very tight.Key Features:Forged alloy blade,Reinforced nylon rim shield safe for use on carbon rims,Integrated spoke-hook wing,105mm x 25mm x 7mm (perfect for seat roll premio or eolo wallet),Net weight (two levers and neoprene sleeve) = 36 grams.
