MLINK™ = MID LINK

Modern full-suspension kinematics have evolved over the years from placing the critical chainstay pivot near the rear axle - producing a flexy and limited system - to a short link pivot in front of the rear wheel, a high-stress system with long chainstays. MLink places this critical pivot in the middle of the chainstay, balancing out these opposing forces for a smooth and efficient system with less flex, less binding, and less bearing and pivot stress.

SOTTO GROUP

When Joe Breeze launched his first full-suspension bikes in 1997, he sought out one of the brightest minds in bicycle kinematics, John Castellano. The MIT engineer and brains behind the Sweetspot suspension system worked with Joe to introduce the Breezer Twister: an XC/Trail bike with an unheard of 130mm of rear wheel travel (remember this was 1997, when downhill forks had 100mm of travel).

Fast forward 15 years, and the guys leading the charge now are the brilliant engineers at Sotto Group, the creators of MLink technology who Joe partnered with to bring the revolutionary system to Breezer. Started in 2006 after a combined 25 years working at Lockheed Missiles, Siemens, Bontrager, Specialized, and Santa Cruz, Sotto is responsible for many of new proprietary suspension systems you see on the market today including the award-winning Switch system, and now MLink.

LONGER LINKS ARE BETTER

Short links do funny things in the real world. On a computer, they look great - super stiff and super easy to adjust wheels path, shock rate, DCSL curves, anti-squat, and anti-rise. But for a given wheel travel, those short links have to move a lot - and quickly. Large rotations and rapid accelerations plus direction changes equal unhappy bearings. Additionally, extremely short links (think eccentrics) maximize the force the suspension system can exert on them, resulting in stiction issues, tolerance problems, accelerated bearing wear, and often catastrophic shor link over-centered issues.

MLink technology places this critical pivot in the center of the chainstay. Breezer's mid link pivot rotates only 3 degrees for 160mm of rear wheel travel - 3 degrees! Less rotation equals super smooth suspension travel, less stress on bearings and pivots, and the MLink system completely eliminates and over-center issues. Short links are simply a shortcut when working to optimize full-suspension kinematics.

DESIGNING FOR BIG WHEELS

BOTTOM BRACKET HEIGHT: Bigger wheels mean your axles are higher up and further out, relative to the bottom bracket. Higher up relative to the BB is great, as you are effectively riding in a valley of confidence between the wheels - making it harder to go over the bars on gnarly downhills and pitch backwards on steep climbs. Further out (longer wheelbase), however, is not good, as this makes bikes that are already stable handle sluggishly. Shortening the rear center and the front center gets you back to a great handling bike, while continuing to take advantage of the benefits of big wheels.

HEAD TUBE ANGLE: How much you have to lean your bike for a given radius turn is determinded by your head tube angle and fork offset. A slacker head tube angle means you have to lean your bike more for a given radius turn. The more you lean, the more likely you are to lose traction or slide out. Instead, you can take advantage of the big wheel's higher axle height by slightly steepening the head tube angle and tucking the front wheel under the frame more. This doubles down on two criticallyimportant big wheel advantages: optimized trail that allows you to lean the bike less for a given radius turn and a shorter front center for predicatable handling and more tire bite through turns.
