SpeedStacks G5 Timer – The Official Competition Timer for Speedcubing
The SpeedStacks G5 Timer is the latest generation of the world's most recognisable speedcubing timer. Used at official World Cube Association (WCA) competitions around the globe, the G5 builds on the trusted StackMat design with improved durability, smarter controls and enhanced reliability for both practice and competition.
Whether you're training for your first competition or chasing a national record, the SpeedStacks G5 delivers the same competition-style timing experience used by thousands of speedcubers worldwide.
