Zipp Service Course 70 XPLR

Engineered Control. Ergonomic Freedom.

The standout innovation of the Zipp Service Course 70 XPLR lies in its distinct drop architecture. Traditional flared gravel bars often tilt your brake hoods inward at extreme, awkward angles, which can cause severe wrist strain and compromise brake-lever reach. Zipp solves this issue completely by combining a subtle 5° flare with a generous 11° outsweep. This hybrid design allows your brake hoods to remain comfortably vertical and natural for pavement riding, while smoothly kicking the lower drops outward to create a wide, ultra-stable platform for aggressive descending.

Why the Service Course 70 XPLR is a Gravel Favorite:

• Gravel-Specific Drop Geometry: Features an ergonomic 70mm reach and a shallow 115mm drop, making it incredibly easy to transition seamlessly between the tops, hoods, and drops without overextending your lower back.

• Vertical Hoods / Wide Drops: The clever 5° flare combined with an 11° outsweep expands the lower drop position by an extra 6cm. This creates massive wrist clearance and exceptional steering leverage over rough terrain while keeping your hoods perfectly aligned.

• Ergonomic Flattened Top Section: Modeled after Zipp's premium road bars, the top section features a subtly flattened, ovalized profile. This provides a natural, hand-filling grip that distributes your upper body weight evenly to prevent hand numbness.

• Robust 6061 Aluminum Construction: Precision-crafted from premium, bead-blasted 6061 aluminum. This material delivers an ideal balance of lightweight racing efficiency and bombproof, impact-resistant durability.

• Generous 100mm Centre Clamping Area: Provides ample space to securely clamp your bike computer, front lights, clip-on aero bars, or a packed handlebar bag for multi-day bikepacking trips.

• Clean Electronic Integration: Fully compatible with internal Di2 bar-end junction boxes, keeping your cockpit exceptionally streamlined and free of messy external wiring.

The Alegro Perspective: In the shop, we highly recommend the 70 XPLR to gravel riders who find traditional 'dirt drops' too extreme. Many gravel bars flare out so aggressively that riding on the hoods feels totally unnatural. Zipp absolutely nailed the ergonomics here. The hoods stay straight for standard road cruising, but the moment you drop your hands down for a technical descent, you get that wide, confident mountain-bike stance. It is an exceptionally comfortable, well-thought-out design that completely transforms how a gravel bike handles.
