A NEW APPROACH TO BMX RACE DRIVETRAINS

Why settle for conventional gearing when you can optimise your drivetrain for performance?

AllYoogs® develops drivetrain systems specifically for BMX Race, focusing on key performance factors: efficiency, weight, pedalling smoothness, gearing ratios and adaptation to each rider’s individual characteristics.

Our goal is to deliver a drivetrain tailored to the demands of BMX Race, helping young riders progress while meeting the performance requirements of elite-level competitors.

THE RIGHT GEARING MAKES ALL THE DIFFERENCE

A bigger gear ratio doesn’t necessarily mean better performance.
The right gearing helps riders find the ideal balance between acceleration, pedalling cadence and speed.
For young riders in particular, gearing should also support their development and growth.
AllYoogs® offers a range of chainring and sprocket combinations to fine-tune gearing to each rider’s needs. 

HOW TO CHOOSE THE RIGHT GEARING

Tension your chain, change sprockets without moving the rear wheel and align it stress!

Winter preparation

BMX RACING PLACES VERY SPECIFIC DEMANDS ON A DRIVETRAIN: explosive acceleration, rapid bursts of speed, quick changes in pedalling cadence and the constant pursuit of maximum efficiency.
Our drivetrains are engineered to meet these demands.

EFFICIENCY: Designed to minimise energy losses and maximise power transfer.
LIGHTWEIGHT DESIGN: Every component is engineered to reduce weight without compromising the demands of competitive racing.
PRECISION: A wide range of gearing options allows each drivetrain to be precisely tailored to the rider and riding conditions.
RELIABILITY: Carefully selected materials and surface treatments designed to withstand the demands of BMX Racing.
