Factor introduces Aluto gravel bike

Factor introduces Aluto gravel bike

Factor has launched the Aluto, a new gravel bike designed to sit alongside the race-oriented Ostro Gravel as a more endurance-focused option. Where the Ostro is aimed squarely at racing, the Aluto is aimed more at adventurous endurance rides.

The frame is optimised for 45 mm tyres, with clearance up to 47 mm at the rear and 52 mm at the front. Compared to the Ostro Gravel, the Aluto runs a steeper head tube angle and shorter chainstays, while a lower bottom bracket and slightly higher stack are intended to add stability and broaden fit options. The result, Factor claims, is handling that stays sharp but with more comfort for all-day efforts.

Practical features include downtube storage and compatibility with both 1x and 2x drivetrains. The bike comes stock with Black Inc.’s HB05 integrated barstem, which uses a shorter reach and flared drops.

Available in “Raptor Blue” and “Quattro Grey,” the Aluto is Factor’s attempt to broaden its gravel range alongside the OSTRO Gravel for those not necessarily looking to race.

Complete builds start from $7,000 / €8,400 / £7,000 with framesets costing $4,000 / €4,700 / £4,000.
