26" wheels

The original 26" mountain bike wheel size is now the smallest of three available diameters. It’s the most flickable, most playful wheel size.

Extended size range

A wider range of sizes than the industry standard provides more options for everyone, from tallest to shortest and all those in between. Because everyone deserves a great ride.

Rack & mudguard mounts

Built-in mounts make it easy to add racks and mudguards for added versatility.

Suspension fork

Shock-absorbing fork allows the front wheel to travel up and down over bumps while the handlebars stay steady, for a comfortable, controlled ride.

Every Trail Ready frame is certified for off-road use.
