BMC – The Bicycle Manufacturing Company
It’s all in the name. At BMC we concentrate on what we do best - making bikes, pure and simple. We focus our energy towards creating the ultimate ride - whether for road, track, or trail, professional athlete, or weekend warrior.Explore our Innovations
Some companies call it the development process. At BMC we call it 'excitement research.' Using cutting edge in-house technology at the Impec Advanced R&D Lab in Grenchen, we simulate prototypes and apply the highest level of engineering, craftsmanship and design to create them.
We combine this process with feedback gleaned from our test rides on the trails and roads that surround our headquarters. Then we repeat, over and over again, until we are convinced that what we have produced is the best it can possibly be. We live and breathe research and development. The loop is so tight that we come full circle on a daily basis, in the design studio and workshop, over lunchtime rides, coffee breaks, and through interaction with our professional athletes. You see, at BMC we take a different approach. Not just to differentiate ourselves from the pack, but to ensure that we live up to our promise of bringing you the most innovative and forward-thinking cycling solutions.
The queen of the legendary classics, Paris Roubaix, is infamous for its pavé. Multiple sections of rough, uneven cobbles place huge demand on both rider and bike. These harsh terrains call for something much tougher. We set out to find innovative solutions to ease the battering that our professional cyclists take on these brutal roads. We figured that if we can make their suffering more bearable, excellent results would soon follow.
TCC – Tuned Compliance Concept
It’s not easy to imagine compliance and stiffness working as one, but Tuned Compliance Concept does just this. The most advanced bikes are designed to be dynamic on the road and cutting-edge BMC engineers understand this as an opportunity in functional design.
The ultimate balance between stiffness and vertical compliance
Vertical compliance refers to the level of flexing on a bike frame. Combined with stiffness - it can consume up to 15% of a rider’s energy. Our Tuned Compliance Concept focuses on minimizing this impact by leveraging the technical know how and expertise gathered from years of bike design, to create the ultimate balance between comfort and performance for a ride that is both forgiving and fast .
Active suspension is not a typical feature built into road bike frames. But this doesn’t mean that there is no suspension at all. In a very basic way all bike frames and forks flex, together with spokes, wheels, seat posts and saddles, handlebars and stems. We introduced thin, low seat stays, offset dropouts, carbon fork tips, and re-designed our seat post to allow the frameset to flex vertically , maximizing what we call angle compliance. In doing so, the disturbing sensations on your ride - the jarring hits, and rocky vibrations are not transferred directly to your body. Your rear wheel stays in contact with the ground, the ride becomes effortlessly fast, no matter how many Paris Roubaix and Flanders cobbled sections need to be conquered.
Once we have ensured that your ride is comfortable, what happens to the frame when you grind those pedals? Oversized downtubes, headtubes, chainstays and fork crowns, are combined with high-modulus carbon fibers to increase the lateral (side) stiffness of the frame. This improves the efficiency of power transferred from the rider to the bike. Not only that, but it also improves the torsional stiffness - making handling more intuitive, lighter, and more precise.
Between a cyclist and his fastest time trial lies one fierce opponent – air. Every cyclist has to fight it. Drag increases with the square of speed. Over the speed of 15kmph, drag exceeds all other forms of resistance combined (roll resistance mechanical friction losses.)
Optimized aero designs, complete cable integration, and huge ranges of adjustability are key ingredients to making you aerodynamic on the bike. Our timemachine line is developed to make you faster than ever. Helping you to exceed your previous time-trial or triathlon personal records by offering you sustainable positions. So the only excuses left when you cross the finish line are your legs, your lungs, and your mind.
The winning formula:
Vmax = p2p x subA
Aerodynamics is not just about the bike, it is the position of the rider together with the bike - the whole picture.
Dubbed p2p, the Position to Perform idea is as simple as it is brilliant. A highly adjustable stem and seatpost lets you create your ideal position on the bike for a sprint, Ironman, or anything in between.
SubA refers to the maximization of aerodynamics through minimizing exposure to the wind. This is generated through three core features; teardrop 3:1, a truncated profile, and tripwire.
Teardrop 3:1The name reflects the frame shape, formed in an aerodynamic length-to-width ratio of 3:1.
Truncated ProfileWe worked a straight breakaway edge into the profile of the bike which reduces the weight while increasing frame stiffness, resulting in optimal turbulence control.
Tripwire technologyWe took our inspiration from aeronautics. Tripwire for the air is created when special wind curbs are molded into the carbon frame, so that a slight amount of turbulence is created directly above the surface. A sort of air cushion forms a wind flow – making you faster.
ACE – 34,000 prototypes in just one year
If you want a 100% optimized bike frame, you’ll have to wait a very, very long time. At least this was the case before we developed ACE - the in-house computer software used daily by BMC’s engineers to digitally simulate each stage and iteration of a new carbon frame. With ACE, we develop virtual prototypes before cutting actual molds, compressing years of testing and prototyping into mere months at the Impec R&D Lab in Grenchen, Switzerland.
ACE - Accelerated Composites Evolution Technology
In 2011 we set out to advance our first-generation teammachine design. We soon realized that relying on human trial and error alone to improve a race bike of this caliber simply wasn’t going to cut it. Collaborating with experts in the field, we developed ACE, or Accelerated Composites Evolution Technology. Replacing traditional prototyping processes, the iterative, computer-modelling program produced more than 34,000 possible frame configurations in just one year. This information enables us to virtually optimize geometrical structure, cross-sections and carbon fiber lay-ups to ensure that any physical prototypes produced are as close to the finished product as possible, thus reducing development time by light years.
With ACE technology, the most relevant performance characteristics of a race bike; weight, stiffness, and compliance, are combined in the best way possible to produce a unique ride and the ultimate in performance. Rather than physically prototyping every iterative stage during the engineering process, it allows us to speed up the evolutionary design process. Driven by more than 200 parameters such as cross-section dimensions, clearances, performance targets, our Finite Element Method (FEM) established a calculation model to determine the absolute real-world performance of the frame. Through complex computations, the characteristics of each iteration of frame design are realized and refined until the optimal combination of all parameters is found.
Picture yourself on your full suspension bike riding a pretty tough trail. After every sharp turn you accelerate. But, imagine if every time you do this, the suspension eats up your forward momentum, robbing you of your fun, and the rewards for your hard work.
APS - Advanced Pivot System
A well-designed full suspension bike offers the control and confidence to ride a trail without hesitation. Ideal suspension systems maximize pedaling efficiency without compromising the ability to soak up the bumps. Our solution is the Advanced Pivot System (APS) which optimizes kinematics and pivot placements, leverage ratios, axle paths and shock dimensions. Iterative calculations fine-tune all the suspension properties of each of our distinctive full-suspension models to achieve the best ride characteristics for any terrain. The result is a light, stiff and compact structure that promotes excellent control and energy transfer for the rider.
When accelerating, an inertial force is generated which attempts to compress the shock system. Our APS solution counteracts this effect. It carefully calculates the pivot points of the rear suspension so that inertial force generated under acceleration is not misdirected into compressing the shock, instead, the chain tension compensates for this effect. As a result, all the pedal power is used for propulsion without any loss of energy through the suspension. The shock system ensures optimum traction, and therefore ensures that power is transferred to the ground.
Our solution to finding the optimal pivot placement, APS achieves this through iterative calculations in order to fine-tune such suspension characteristics as leverage ratio, axle path, and the amount of kickback. The unified rear triangle is linked to the main frame by two short links, with the upper link actuating the shock. The result is a light, stiff and compact structure. Impacts are absorbed by the shock system, providing excellent comfort for the rider.
Another example of our forward-thinking cycling solutions from the Impec R&D Lab and the efforts we go to put the rider in the middle of the equation, the advanced pivot system offers the rider the perfect combination of efficiency, traction, and comfort.
TractionTo achieve just the right amount of travel for each of our distinct models we optimized the leverage ratio, ensuring the optimal balance between progression and small bump sensitivity.
ControlLow suspension ratio means greater oil flow and energy dissipation. Pick your line and let the bike do the rest.
EfficiencyThere is a lot to be said for keeping the rubber side down. With less time in the air you cover ground faster.
