I went into this review with pretty modest expectations… but the RockBros Pegasus PGZ-RH genuinely surprised me.
For A$3500, this bike packs in a level of spec that is honestly hard to ignore: Shimano 105 Di2 Groupset (Complete!), 50mm deep carbon wheels, a clean, fully integrated cockpit, and a frame that looks far more premium than the price tag suggests. But this isn’t just a bike for cruising to the café and looking pretty.
The PGZ-RH feels like a bike that can actually be ridden properly, whether that’s fast bunch rides, hard solo efforts, timed events, or even racing. It looks sharp, feels purposeful, and comes across as far more capable than many people would expect from a brand like RockBros.
When you compare it to similarly priced bikes from major brands like Trek, Merida, Giant and others, it’s hard to find anything that offers this much value in one package. That’s what makes this bike so interesting. It doesn’t just tick boxes on a spec sheet; it genuinely looks like a serious road bike at a price point where compromises are usually everywhere.
So in this video, I break down what the RockBros Pegasus PGZ-RH is all about, who it might suit, and why this could be one of the most value-packed road bikes currently out there.
