Will my bike have a curved top tube?
Smaller frames have a top tube that dips down as it approaches the seat tube. This design makes for a lower standover height, which is good for shorter riders because it allows them to straddle their bike more easily. Larger frame sizes have a straight top tube because taller riders with longer legs typically don’t have the same issues with standover height.

Fit for every rider
Marlin comes in seven frame sizes to suit riders of any height, and Smart Wheel Size ensures you’re on the fastest wheel that fits. The smallest sizes even come with short-reach brake levers and narrower handlebars that give smaller riders better comfort and control.

High tech, high value
Marlin looks and feels great. It’s packed with features usually found only on more expensive bikes, like a stylish frame with internal shift cable and brake hose routing, which can help your cables last longer by protecting them from the elements.

Shimano CUES
Inspired by rider demand for trouble-free drivetrain longevity and performance, Shimano CUES offers a new foundation for versatility and durability across a range of both electric and standard bikes. CUES features Shimano’s new LINKGLIDE drivetrain technology for significantly increased life on wear items like chain, cassette, and chainrings.

A better way to produce aluminum
Starting in 2024, we began removing high-emission aluminum from our manufacturing and replacing it with low-emission aluminum made with renewable energy. By October 2025, nearly every alloy bike we make - this one included - had made the switch, driving a major drop in our footprint.

Shimano LINKGLIDE
LINKGLIDE technology has been specifically engineered for incredible durability while still delivering smooth and decisive shifting – along with a great pedalling experience. Available exclusively on Shimano CUES drivetrains.
