What do you choose when you want a gravel bike that strikes the perfect balance between all-day adventure and race-day speed? The Factor Ostro Gravel—better known as the Aluto—is the answer.
Finished in this striking colourway, this build started life with a SRAM Force E1 1x drivetrain before being upgraded to the flagship SRAM Red E1 1x setup. Black Inc takes care of the cockpit and seatpost duties, while rolling stock comes courtesy of our own CCACHE GTR45 wheelset.
For this particular build, the rider opted for a custom GTR45 configuration with traditional alloy spokes instead of carbon. While the weight penalty is minimal, the result is a slightly more compliant ride quality and a timeless aesthetic that perfectly complements the bike’s balanced character.
The GTR45’s generous internal rim width allows modern gravel tyres to sit optimally, creating an efficient tyre profile that delivers confident handling and speed across everything from smooth fire roads to technical singletrack.
