BH knows that most cyclists aren’t actually road racers. So why do you have to buy the latest aero road race bike to get the latest in aerodynamic performance? Their answer, the new Quartz Aero Disc, mixing all-day comfort & more relaxed endurance road riding geometry with all the incremental aero gains of the latest & fastest race bikes.
BH Quartz Aero Disc aero optimized endurance road bike
Comfortable carbon bikes have become more commonplace, especially since industry & rider alike have both embraced endurance road, all-road & even gravel road bikes. But besides a few unique outliers like the 3T Exploro which hyped aero gravel, few of these comfort-focused road bikes have put aerodynamics at the forefront. That’s where the new 2019 BH Quartz Aero Disc comes in, taking advantage of carbon’s ability to be both shaped for aerodynamics and tuned for vertical flexibility & rider comfort.
The Quartz Aero Disc is a comfortable gran fondo style endurance road bike bringing aero gains to the masses. The frame itself is built on slim shaped tubing for a small frontal profile & relatively deep aerofoil profiles.
But its aero gains don’t stop there, BH employed a separate cover over the front of the headtube (not quite as seamless as it appears in the studio photos, we think) that smooths air over the bike and cleanly routes cabling internally.
Quartz Aero comfort endurance road Geometry
The new bike is designed for long days of cycling and for riders not addicted to competition, but at the same time happy to shave a few seconds off their time thanks to decreased aero drag. With that the new Quartz Aero Disc gets a longer head tube & taller stack figures for a more comfortable upright riding position, available in six frame sizes.
Even though the front end of the Quartz Aero Disc is longer and more stable, the rear center is compact, and together with a shirt seattube, the bike offers plenty of drivetrain stiffness & quick acceleration.
Quartz Aero comfort endurance Tech Details
The Quartz Aero Discs sticks with a classic 27.2 seatpost to filter out vibrations, on top of the otherwise tiny, dropped seatstays for comfort.
Tire clearance is critical on an endurance road bike, and the new Quartz delivers with room for up to 32mm rubber. Weight also remains surprisingly low at a claimed 950g (size M).
The Quartz Aero Disc features flat mount disc brakes, 12mm thru-axle, and a BB386 EVO bottom bracket. All routing is internal, including Di2 compatibility.
BH Quartz Pricing & Availability
The new Quartz range actually includes the disc brake bike, but also a less aero rim brake version that shares most of the same aero comfort tech, minus the nose cone. Each is available in four different spec levels. The rim brake bike starts at 1900€, and a Quartz disc without the aero headtube cover from 2400€.
The proper Quartz Aero Disc then is available in a 2600€ build, a 3700€ option, and for 4700€ as the top-level Quartz Aero Disc 4.5 with an Ultegra Di2 build kit and carbon Vision Trimax 40 wheels.
