Canfield Balance Formula (CBF)
Rear Suspension Design
Until now, most suspension systems have focused solely on the instant center. CBF™ focuses on designing rear suspension around the Center of Curvature (CC).
CBF™ points the chain-line and corresponding drive forces around the top of the chainring through 100 percent of the travel. This results in maximum pedaling efficiency regardless of terrain, where you are in the travel, or what kind of power you’re putting down. All the power you put into the pedals goes directly into turning the rear wheel.
Center of Curvature (CC)
The Canfield brothers stumbled upon the importance of CC after years of designing big-hit, rampage-ready bikes. The instant center constantly shifts throughout the stroke of suspension in multi-link bikes, causing the rear wheel to depart from the perfect-arc rotation that’s known only to single-pivot bikes (which is a less-than-perfect design for most other suspension criteria).
However, if you connect the rear axle at any point on its path with the ever-changing instant center, the area where all those lines intersect for the entire range of travel is the center of curvature. On most multi-link bikes, the CC changes location in wild ways as the rear wheel moves through travel, sometimes over an area as large as several square feet.
Supple. Supportive. Bottomless.
Leverage Ratio is the mechanical advantage of the wheel over the shock at a given position in the travel. Our goal when designing each Revel is to create a leverage ratio curve that provides high shock sensitivity early in the travel to soak up small bumps and hug the ground while retaining support throughout the mid stroke and the bottomless feel deep in the travel that Revel’s are known for.
Anti-Rise is a metric showing a bike’s ability to control braking-induced shock movement. Our goal when designing each Revel is to create an anti-rise curve that minimizes the effects of braking on shock movement and retains active suspension movement when you need it most.
Anti-Squat is a metric showing a bike’s ability to control pedaling-induced shock movement. By utilizing the CBF™ suspension platform, we are able to design each Revel to have exceptional pedaling efficiency while remaining active over rough terrain.
Composite Material & Process
Our rims are made from the brand new FusionFiber™ technology developed and manufactured in an aerospace facility in southern Utah. There’s no environmentally harmful or brittle epoxy in this carbon- it is a toughened, high performance composite polymer that makes for a significantly more durable, lighter, and better riding wheel with a nice damped feel. It’s unlike any composite material the bicycle world has ever seen.
Our FusionFiber Manufacturing Process
We partnered with some friends who developed this technology in one of the world’s leading aerospace manufacturing facilities in America to come out with the first product made from it- the RW30 rim.
The manufacturing process starts by laying out the rims and cross-pling robotically, leaving no space for human error or inconsistencies. The rims are then flash welded together, with an exponentially faster cure time than current rim technology and are in a completely controlled environment so every rim comes out the same, every time. When the rim pops out of the mold, there is no epoxy resin to be scraped or sanded and it needs no clear coating.
Because Titanium is Magic
When we sit down at Revel to design, engineer and produce a bike, the first question asked is the materials question. What is the right material for each application? Well, in walks titanium. A hard to beat reliable, lasting, strong material that provides a rider with the comfort, strength and ridiculously good ride quality needed from the bike to take them the distance. Although we adore our carbon bikes, we are beyond thrilled to include Revel titanium in our fleet.
We use the highest quality Grade 9 3/2.5 titanium for our tubing, and 6/4 titanium for the head tube, bottom bracket shell, and machined bits all over the frame. The wonder material has so many excellent ride quality attributes: 43% lighter than steel, higher strength-weight ratio than aluminum, significantly more resistant to crash-damage than carbon, and the best vibration damping properties of all three listed here.
Some like it cold
We use a cold forming process to shape our tubes to best maintain the strength of our titanium but optimize it for lateral stiffness and compliance where we want it. We like to say we use a carbon engineering oversight to make our titanium bikes, and we’re proud of all the modern features we’ve stacked into these frames. Our beautifully CNC machined dropouts made from the best of the best titanium alloy really tie our modern, practical, and well-thought-out frames together.
