JK new carbon handlebar redefines my handling requirements. 『I believe energy and persistence conquer all things.』 JK new handlebar is made of carbon fiber with graphene- tough, shock-absorbing, and dissipates heat, which will increase safety. It is lighter than aluminum alloy, which greatly improves handling. There are two upward sloping angles of 67 and 8.5 degrees from the level of the front of the bike, and an 8.5-degree rearward tilt, which is the "golden angle" that Joe, the founder of the bike, has carefully invented for the ergonomics of the rider. The combination of these advantages redefined my requirements for handling! #josephkuosac #brompton #bromptonlovers #bromptonlife #bromptontaiwan #bromptonbicycle #bicycle #bike #bikes #bici #velo #igbikes #biketuning #bikeboutique #bikefashion #lifequotes #carbon #carbonhandlebar #handlebars #grip #gc38c #c38c #pushmyself

JK gC38C 349 Wheelset‧Born from Reflection 『By prevailing overall obstacles and distractions, I may unfailingly arrive at my chosen goal or destination.』 The composite materials used from JK gC38C provide performance, lightweight and high quality at the same time is an outstanding achievement for JK. Different bikes should be designed to meet different needs- this is JK founder: Joe’s philosophy. Smaller wheel bikes take less time to brake and dissipate heat. Their hubs are too wide for shorter rim diameters. However, the angle of road bikes’ spokes are too small to withstand a normal loading on a small wheel like the 349. Therefore the gC38C incorporates graphene to increase heat dissipation and enhance strength and toughness while reducing the width. The hubs have been strengthened, and the spokes have been strengthened by cross-structured design. "There's got to be a better way," said Joe, and that's how he come up with the JK gC38C 349 wheelset. #josephkousac #brompton #bromptonbicycle #bromptonlovers #bromptonlife #bromptontaiwan #igbikes #bike #bicycle #bici #velo #bikes #wheelset #carbon #carbonwheels #c38c #gc38c #biketuning #bikeboutique #bikefashion #lifequotes #lifestyle #life

JK gC38C Wheelset Wheel Marker─『Glow』‧The Beauty of Dim Light in Night Riding 『The best preparation for tomorrow is doing my best today.』 The gC38C Carbon Fiber Wheelset is made of graphene and carbon fiber, which enhances the heat dissipation and toughness of the wheelset, making it a great choice for Brompton and many other 349 trail bikes. JK has developed three versions of the wheel markings to meet the aesthetic needs of different groups. The glow-in-the-dark wheel markings have a distinctive atmosphere, as the wheel frame glows brightly during night riding, and the gC38C lettering and the sense of rotation become more pronounced than during the day. When the sun goes down, the color will be lost, JK wanted to use the frame to emit a ghostly light, so that Brompton can be the center of attention even at night! #josephkuosac #brompton #bromptonlovers #bromptonlife #bromptontaiwan #bromptontuning #gc38c #c38c #carbon #carbonwheels #wheelset #igbikes #bikes #bicycle #bike #biketuning #bikeboutique #lifequotes #lifestyle #bikefashion

JK hubs are precise and tough - creating harmony in the ride. 『If I don’t go after what I want, I’ll never have it.』 The balance and harmony between the front and rear wheels of a bicycle is a consistent strength of the JK hub. It has two front and four rear bearings, which is the realization of precision coaxial technology. In addition, the narrow design allows the angle of the spokes to be more upright, and the strong rigidity of the wheelset is naturally revealed. JK's gC38C and A22C wheelsets are equipped with these hubs to ensure the durability of the wheelset. #josephkousac #brompton #bromptonbicycle #bromptonlovers #bromptonlife #igbikes #bikes #bike #bicycle #biketuning #bikeboutique #hubs #bikehub #bicyclehub #gc38c #a22c #wheelset #lifequotes #c38c #spoke #spokes #bromptontaiwan

Derived from its pioneering meaning to JK, we re-design the first easy wheels using JK C38C logo on them, showing JK's affirmation and making the set of wheels on Brompton have a classic premium look. With a consistent aesthetic style, these two most important primary and secondary wheels of Brompton just make Brompton become a tressure. #josephkousac #brompton #bromptonbicycle #bromptonlovers #bromptpnlife #igbikes #bike #bicycle #biketuning #bikeboutique #c38c #gc38c #ezwheels #wheelset #ezface #bikephoto #bromptonbike #bromptonlifestyle #life

The evolution of the Joseph Kuosac C38C carbon fiber wheelset When Joseph Kuosac was formed in 2010, the C38C for Birdy's 355mm was  the first carbon fiber wheelset created by JK. The popularity and success of the Birdy 355 inspired JK founder, Joe Kuo to expand the company's range of wheelset options to the Brompton platform. He believed that the Brompton platform would be an ideal bicycle due to its design concept of small, compact and lightweight. JK pioneered the carbon fiber wheel concept for Brompton bicycles.  Several other companies have entered the market, but Joseph Kuosac remains the industry leader with the largest installed base around the world.  The legendary aC38C created a cult following and rode to victory in Brompton World Championships races around the world.The current generation gC38C has evolved into the industry standard with its unique graphene blend with Toray’s carbon fiber resulting in a lightweight, strong and attractive package. Push Myself is the driving force behind JK.  It's time to push yourself to the next level of your cycling journey on a set of Joseph Kuosac wheels.  #josephkuosac #pushmyself #rideon #c38c #gc38c #brompton #bromptonlife #birdybike #carbon #carbonwheels #carbonwheelset #igbikes #bikes #biketuning #bikeboutique #bromptonbicycle #bromptonlovers #bicycle #bikephoto #bikephotography

JK gC38C - Strength in numbers The gC38C 349 wheel set is composed of 28 spokes that are connected to the wheelset with a double cross braid. Together with the narrow hub developed by JK, the angle of the spokes provide strength and rigidity making the gC38C a lightweight, professional grade carbon fiber wheelset. A professional grade wheelset needs to be strong enough to endure the punishment of competitive cycling.  The JK gC38C is engineered for durability, strength, resilience and safety.  The 38mm sidewall is not only aerodynamic but it is strong and durable with load-bearing capacity to withstand a static load of 10,000kg with reliability in excess of 10,000 kilometers.  A normal rider may not ever experience these conditions but take comfort in knowing that your Joseph Kuosac wheelsets are built to last.  Click here to view the static load test. You have a lot riding on your wheelset and tires. Don't take chances with inferior products.  If you are looking to upgrade your stock Brompton, please consider our wheelsets and tyres.  With JK, the benefits outweigh the competition. #josephkousac #igbikes #bike #bicycle #biketuning #bikeboutique #c38c #gc38c #wheelset #carbon #bikephoto #carbonwheels #bikephotography #brompton #bromptonlovers #bromptonlife

JK gC38C 349mm for Brompton - Not all carbon fiber wheels are created equal Joseph Kuosac pioneered the carbon fiber wheelset for Bromptons.  There are thousands of Bromptons rolling on JK carbon fiber wheelsets around the world.  Our success has spawned many competitors in recent years.  Despite this, JK continues to innovate and improve upon our original carbon wheel. The gC38C is the latest generation of carbon fiber wheels.  The advancement of technology has allowed us to eliminate the use of aluminum along the braking area.  A new material called "graphene" is now integrated into the carbon fiber material to help dissipate heat during extreme braking. JK sources carbon fiber material from Toray Industries, a leading manufacturer of industrial materials.  Their carbon fiber products represent the highest modulus PAN-based carbon fibers available on the market today. Other features of the gC38C include braided wheel construction utilizing narrow hubs with double cross spoke weaving to provide a higher load bearing capacity. Because you have a lot riding on your Brompton, we use 28 spokes front and rear. Not to make a lightweight wheel, but to provide a stronger, safer wheelset.   New physical features include reinforcement of the valve stem hole and the water drainage hole to prevent material cracking.  Not only are our gC38C good looking, they are built to last.  Whether you choose black label, white label or our new glow in the dark label, you'll know that you're riding on the best carbon fiber wheels available from Bromptons today. #josephkuosac #igbikes #bike #bicycle #biketuning #pushmyself #c38c #gc38c #wheelset #carbon #rideon #carbonwheels #bikeboutique #brompton #bromptonlovers #bikephotography #bromptonlife #bromptonbicycle

Cracking the myth about the price of carbon wheels - Part 1 Fact:  Aluminum wheels have been the mainstay of the cycling industry for about 50 years.  Carbon fiber wheels have been on the market for just a little over 10 years.  They have gained in popularity in the last 5.  Carbon fiber wheels for Bromptons are rare.  Approximately 1 in 10 Bromptons are riding on carbon fiber wheelsets.  Carbon fiber commands a premium over aluminum because they are manufactured in smaller quantities and the manufacturing process is more complex than aluminum.  Plus the material cost for carbon over aluminum is approximately 50%.  At Joseph Kuosac, the C38C family of carbon wheels utilize carbon fiber from the Japanese firm, Toray Group.  They are a respected name and  are one of the world's leading suppliers to the automotive, aircraft, marine, train and bicycle industries. Bromptoneers buy JK carbon fiber wheels because they appreciate quality and performance.  They are willing to pay a premium for a wheelset that will give them faster spin up, better ride comfort and handling and an increase in road feel versus aluminum rims.  The JK C38C not only is sporty looking, it is aerodynamically designed yet strong enough to withstand the rigors of high performance cycling.  Joseph Kuosac wheels have ridden cyclists to victory at the Brompton World Championships. You have a lot riding on your wheelset and tyres.  Don't take chances with inferior products.  When you buy JK, you buy the best.   #josephkuosac #pushmyself #jk #bike #rideon #c38c #brompton #igbikes #bromptonlife #bromptonbicycle #bromptonlovers #biketuning #bicycle #gc38c #carbonwheels #wheelset #bikeboutique #bikephoto #lifequotes #lifestyle #carbon wheels

Cracking the myth of JK's carbon fiber wheelset - Part 1 There is a continuing myth in the cycling world that lighter is always better. This is not always the case; in particular with the carbon fiber wheelset. Certain wheelset manufacturers reduce the weight of their wheelsets by using fewer spokes. Some use as little as 14 spokes. Depending on range, Joseph Kuosac uses 20 to 28 spokes in their wheelset designs. The reason for this is because each wheel must be capable of withstanding the rigors of competitive cycling. Fewer spokes threaten the integrity and strength of the wheel The more spokes, the stronger the wheel. The JK gC38C is designed for competition. The high performance gC38C is engineered for durability, strength, resilience and safety. The new design incorporates graphene which is a carbon element that is 200 times more resistant than steel and five times lighter than aluminum. The common goal is to reduce the overall weight of the bicycle. There are many other components that can be swapped and modified to reduce weight but those parts may not compromise safety. You have a lot riding on your wheelset and tyres. If you are looking to upgrade your stock Brompton, please consider JK wheelsets and tyres. With JK, the benefits outweigh the competition. #josephkuosac #pushmyself #rideon #c38c #brompton #bromptonlife

JK and SwissStop:  The best wheelsets require the best brakes Our customers buy our gC38C carbon fiber wheels because they demand the very best.  Speed, performance and quality are of the utmost importance.  Stopping is important too.  Carbon fiber wheels require a special compound and cannot use conventional brake pads.  That's why JK has selected SwissStop brake pads for carbon wheels.  SwissStop brake pads offer excellent modulation, cooler temperatures and great wet weather stopping performance. The JOSEPH KUOSAC name is printed alongside SwissStop on each brake pad. The bests stand together!  #josephkuosac #pushmyself #rideon #swissstop #c38c #brompton #jk #bromptonlife #brakes #brakepads #wheelset #tuning #gc38c #bromptonlife #bromptonbicycle #bromptonlovers #carbonfiberwheels #biketuning #igbikes #bikephoto #life #bicycle #bromptontuning

Beware of counterfeit JK Products! Buy only from authorized JK dealers to guarantee authenticity and quality! In recent years, counterfeit JK products have been making their way to the market. Upon examination, we have found differences in both quality and design of these counterfeits. When compared side to side, the differences are clear. All Joseph Kuosac Professional products are manufactured to exacting standards and go through a rigorous Quality Assurance and testing process before they can be approved for shipment. Counterfeiters don't do this. They simply make a cheap copy, slap on a fake label and discount the price heavily. If you find a JK product advertised for less than MSRP, then it's likely a counterfeit product. What's more, JK sells through a tight distribution channel via authorized JK dealers. We do not sell online and we do not sell direct to consumers. If you buy from a party that is not an authorized JK dealer, there is a possibility that you are not buying a genuine JK product. Please do not support the counterfeit market. Your safety on the road is of upmost importance to us and we only manufacture quality tested products. Thank you for your continued love and support!

Joseph Kuosac Professional is the choice of champions! The winners of the Brompton World Championships rode to victory on JK 349 C38C carbon fiber wheelsets in both Xiaobu and Singapore. The second generation of the famed C38C now blends graphene and carbon fiber into the wheelset to reduce weight while improving rigidity and shock absorption and while increasing heat dissipation under hard braking. The narrow width of the rim allows for use of narrower tyres which improves aerodynamics while reducing road resistance. Feature improvements of the C38C include the creation of a water drainage hole and a reinforced valve opening collar. Available in black or white sidewall lettering, JK introduces another innovative first....fluorescent sidewall lettering which greatly improves visibility when cycling at night. #JosephKuosac #pushmyself #rideon #c38c #brompton #bromptonsg #bromptonlife #bromptonworldchampionships

Secrets of Joseph Kuosac Professional revealed! - The significance of the spoke! The wheel spoke is the unsung hero of the bicycle. It rarely gets recognition for its importance or design. Depending on model, there are 24 or 28 spokes on each JK C38C carbon fiber wheel. Working together, these spokes provide the rigidity and strength of the C38C. Interlaced with the JK narrow hub and the composite graphene and carbon fiber rim, the spokes are the backbone to create a spiritual cycling experience on your Brompton. One unique feature of the JK C38C: the spoke head, or nipple is hidden inside of the rim and not exposed. Why do we do this? To increase the strength while reducing wind drag. The result: each C38C can withstand a static load capacity of 1,000kg per wheel and have a lifespan of over 10,000 kilometers. Ride with confidence on JK 349 C38C carbon fiber wheelsets! #josephkuosac #jk #gc38c #spoke #pushmyself #rideon #c38c #brompton #bromptonlife #wheelset #碳纖維輪組 #bike #bicycle #bikeboutique #bikephotography #lifequotes #life #igbikes #單車 #tuning #自行車
