A gravel-oriented bike gives you more freedom in how and where you ride. Compared to traditional road or mountain bikes, gravel bikes allow for wider tire clearance, which means more comfort, more stability, and a more forgiving ride — especially when the pavement ends or conditions aren’t perfect. Instead of limiting yourself to pristine pavement, a gravel bike opens up what you can ride and where you can go.

The Apollo takes that versatility and removes the usual upkeep that comes with it. Whether you choose flat bar or drop bar, the Apollo is equally comfortable on bike paths, back roads, city streets, and gravel routes, making it a great choice for riders who want one bike that adapts to different rides without extra maintenance or prep.

With the stock setup, the Apollo clears up to a 700c x 53mm tire, giving you plenty of volume for comfort, traction, and confidence on gravel and mixed terrain.

The Apollo frame and fork are also 650b compatible. Swapping to a 650b wheelset allows you to run wider tires at lower pressures, which can increase comfort and grip on rougher surfaces or loaded rides. The bike ships with 700c wheels, but riders looking to fine-tune ride feel or expand terrain options can easily make the switch by adding a 650b wheelset.

Titanium is prized for its naturally smooth ride feel and excellent vibration dampening, which helps reduce fatigue on longer rides and rougher surfaces. It’s also exceptionally strong for its weight and highly resistant to corrosion, making it well suited for year-round riding in wet, muddy, or salty conditions.

On the Apollo Titanium Drop Bar, titanium pairs beautifully with the belt drive and internally geared hub, creating a bike that’s comfortable, durable, and built to last for years with minimal upkeep. And yes — it also has a tendency to attract a few envious stares along the way.

Yes, standard rear racks and fenders are compatible.

While we’re not able to change gearing prior to shipping, it is possible to adjust the gearing after purchase. On the Apollo, riders can swap the front sprocket to a 46T using the stock belt and rear sprocket to achieve a lower overall gear range.

If you’re interested in gearing options outside of the stock belt setup — including different sprocket combinations or belt lengths — we recommend getting in touch with our Customer Service team. We'll be happy to walk through compatibility, parts requirements, and what options make the most sense for your riding needs.

Priority does not offer a drop bar–to–flat bar conversion kit for the Apollo. That said, converting a drop bar Apollo to a flat bar setup is absolutely doable.

Because the conversion requires sourcing and installing a Shimano Alfine 11 flat-bar shifter, along with additional cockpit components — including a handlebar, grips, brake levers, and new cables and housing — we strongly recommend working with a local bike shop. A shop can help ensure proper compatibility, installation, and setup so the bike rides and handles as intended.

If you have questions about parts compatibility or want help deciding if a conversion makes sense for your riding style, our Customer Service team is always happy to help point you in the right direction.
