It's right for you if...

Like 60% of women, you prefer the fit and feel of parts made for women, like a Women's Specific Design saddle. You want a single durable, ultra-versatile gravel bike that's ready for adventure. Gravel? Check. Pavement? Check. Multi-day bikepacking? Check. Foul-weather commuting? Check. Check. Check.

The tech you get

A 300 Series Alpha Aluminum frame with massive tire clearance and adjustable Stranglehold dropouts that make it easy to fine-tune your geometry or run singlespeed, a carbon fork, 12mm thru axles, a 10-speed Shimano Tiagra drivetrain, a wide-range 11-34 cassette that's great for climbing, fender and rack mounts, flat mount hydraulic disc brakes for all-weather stopping power, a Women's Specific Design saddle, and wide 700x35 Schwalbe G-One tires for added stability and traction.

The final word

Bring it on, gravel! Checkpoint ALR 4 Women's is a high-value gateway to a world of adventure. It's rugged, fast, comfortable, and has an amazing amount of tech for its price. Though it's made to stand up to the rigors of gravel roads, the frame geometry and accessory mounts make it a great choice for road rides and commutes, too.

Sizing & fit

The charts below show our recommended sizes based on height, but there are some other factors, like arm and leg length, that determine a great fit. That’s why you’ll see some overlap in our recommendations. Not every rider who’s 5´8˝, for example, will fit on the same size bike. The best way to find your perfect fit is to consult the experts at your local Trek retailer.
