The Nucleon 16 is a high-pivot 29er enduro bike with a mullet option in the 160 to 180 mm travelcategory that uses a new type of shifting technology: the Supre Drivetrain from Cedric Eveleigh‘sCanada-based development company LAL BIKES. Earlier Nucleon models from NICOLAI, such asthe Nucleon DH or the Nucleon Evo, also utilized alternative shifting concepts and combined themwith a high-pivot suspension design. These bikes used a modified 14-speed ROHLOFF gearboxwith the axle positioned at the level of the swingarm pivot point well above the bottom bracket. Aprimary drive to the gearbox and a secondary drive from the gearbox to the rear wheel were required.Suspension and shifting performance, robustness and durability of the early Nucleon bikes wereexcellent. However, the gearbox, including the housing and design-related additional components,caused a weight disadvantage. And even the precise, high-quality ROHLOFF transmissions neverquite matched the efficiency of a derailleur system when shifted under load.With the Supre Drive, NICOLAI can now for the first time optimally use the performance advantagesof a high-pivot suspension in a long-travel enduro bike, with 1x12 setup and 510% total gear ratio.To better understand what is so ingenious about this, it is first necessary to take a look at the twokey technologies in detail as well as their specific details and features.
