May 2022 · Stu Kerton
Hybrid do-it-all with a bit of edge and attitude, just as happy around town as it is on the byways
Capable on the gravel and road
Good spread of gears
Excellent hydraulic brakes
Reflective detailing is eye-catching
Flat bar makes filtering through urban traffic trickier
Mar 2020
Smooth, fast, and utilitarian—this commuter has it all.
Future Shock in the head tube smooths the ride
Plenty of go-fast and hill-climbing gearing
Part smooth/part knobby, 38mm-wide tires
There are more affordable commuter/fitness options out there
Sep 2019 · Warren Rossiter
A fuss-free commuter with a commanding ride position and a nicely understated style
Excellent kit choices, finish, plenty of mounts
Gearing is great for around town but isn't fast if you head out
