HYPERGLIDE+
HYPERGLIDE+ dedicated chain delivers greater chain retention, improved shifting efficiency, and smoother transmission over rough terrain.
Benefits
- Improved chain retention encourages more aggressive all-terrain riding and relieves chain-issue anxiety.
- Smoother drivetrain transmission and enhanced shifting performance sharpens riders’ concentration and improves acceleration.
- Better chain engagement cuts abrasion, reduces maintenance, and lengthens the lifespan of the chain.
LEAVE TIME BEHIND
- It's time — to find out what really matters. The freedom of the open road, crisp mornings and fiery sunsets. Laughter filling the air and then trailing off. Nature, unfolding as you roll. Breathtaking vistas that stop you in your tracks. Coffee stops and camaraderie. Route prep and weather checks. Rain breaks and sunny bursts. Mad dashes. Racing each other to the top. And then kicking back... It's about time — and it's about leaving time behind. Tuning into tranquillity. And shifting into oneness.
