Specialized Crux 5 Sport Shimano GRX 800 (2027)
The Crux 5 was born from the fastest gravel race bike ever made. Not just because it’s the lightest. Not just because it’s our most aero. Not just because it handles dirt like a Tarmac handles pavement. But because it delivers the lowest real-world Time to Finish of any gravel bike ever made. Crux 5 turns more of your effort into pure speed—validated for real race courses, real terrain, and real riders. When the goal is the top step, nothing in gravel gets you there faster.

Complete your Ride
We had an outstanding experience at Cyclerie! We purchased two Aventon e-bikes, and the entire process was exceptional from start to finish. The staff took the time to help us choose the perfect bikes for our needs, recommended all the right accessories, and even installed our bike rack on the car before we left.
I had a terrific experience at Cyclerie! I love the bike I bought and working with Skip was great. He told me about customizing features that are available on the bike if you use the Aventon app.
I enjoyed my buying experience at Cyclerie. Ideal location, easy to get to, easy access to trails to test ride. … Salesperson was helpful, knowledgeable and easy to work with. No pressure to buy.
