I've been riding the G4 for a few weeks now. I've added some good MTN bike pedals, a triangle bag, a shock seatpost and a shorter stem. The bike rocks. It's no featherweight, but for an entry gravel with upgraded features it can't be beat. The steering head is massive and could withstand a nuclear blast. The groupset is entry, but works well enough. I'll ride mechanical into the grave. Sure a Shimano or SRAM would be nice, but the microshift groupset works fine. Gearing is awesome for most offroad excursions, but steep stuff will have you hunting for more gears. Overall very pleased with the brand. I tried comparing prices with other entry drop-bar bikes and this one was a winner.
