Hidden in plain sight, BH drops the G7 Pro

G7 platform now available with rim brakes

When BH launched the G7 in 2015 it was only available with disc brakes, making it one of the early aero disc bikes. This was great for those looking to upgrade to a race-ready disc roadie, but not so great for consumers less keen to make the switch or pro riders on BH sponsored teams with the UCI’s slow uptake of the technology.

For the past few weeks, BH has been hiding the new G7 Pro in plain sight under the Direct Energie team at this year’s Tour de France. The bike was also teased at this year’s EuroBike Demo days, although details were a bit slim. Now BH has lifted the veil on the new bike under the guise of the “Aero Revolution”.

For the new bike, BH has also dropped the seatstays, which should improve compliance

When it came to aerodynamics, BH used much of what it had learned with its pro level G7, and says it further modified the tube shapes not only to make the frame more slippery to the wind but also to handle the forces of rim brakes — an interesting point to make given it’s usually the other way around.

The frame uses a monocoque construction and a mix of Toray T80 and T50 fibres to balance rigidity and weight. BH has also employed its internal compaction techniques to achieve uniform tube thickness, remove any excess material and to eliminate bubbles, imperfections and the like in the carbon.

Claimed to weigh 810g, it’s not the lightest frameset out there, but it’s still respectable.

Sloping geometry

BH has employed the same sloping geometry as the G6 Pro, which in a size medium sees a 557mm top tube, 73-degree head angle, 72.5-degree seat angle and 402mm chainstays.

When we reviewed the BH G6 Pro we found it to be a bike that didn’t like to dawdle, and with the same measurements all around we’d guess the new updated frame will continue that pedigree.

For the new bike, BH has also dropped the seatstays, which should improve compliance a bit, and it’s also moved the rear direct mount brake from underneath the bottom bracket back to the standard seatstay mount — a good move in our book.

The new frame sees an internal cable guide system that’s said to offer max protection and reliability for both electronic drivetrains, and is said to make replacements very easy, too.

BH has also added a new patented clip system inside its uncut seatmast/seatpost to accommodate the internal Di2 battery.

The new G7 Pro will be available in five sizes, and pricing is to be announced
