The Polygon Tambora G4 is designed for riders who want a versatile gravel bike that feels fast on tarmac, stable on rough surfaces and dependable on longer adventure rides. Built around a lightweight ALX gravel frameset and paired with a carbon rigid fork, it offers a balanced ride with sharp handling and reduced front-end weight.
The drivetrain is based around the proven Microshift Advent X 1x10-speed system, giving you simple shifting and a wide usable range for climbs, flats and mixed terrain. A 40T alloy crank works together with an 11-48T cassette to provide practical gearing for recreational gravel rides, commuting and fitness riding.
Braking is handled by Tektro MD-C550 mechanical disc brakes with 160mm rotors, delivering dependable stopping power and easy maintenance. This makes the Tambora G4 a practical option for riders who want confident braking performance without the added complexity of a hydraulic system.
The wheelset uses double-wall alloy rims and is matched with VEE Rail 700x40c tubeless-ready tyres, giving the bike comfort, grip and puncture-reducing potential when set up tubeless. The tyre clearance and gravel-focused geometry help make the Tambora G4 suitable for everything from weekend exploration to daily riding.
Comfort and control are enhanced by a thoughtful finishing kit, including a Selle Italia Model X saddle, alloy seatpost and a 16-degree flare handlebar for added stability on uneven terrain. The result is a gravel bike that feels modern, practical and ready for adventure.
If you are looking for a dependable gravel bike in Malta with modern 1x gearing, carbon fork performance and tubeless-ready wheels, the Polygon Tambora G4 is an excellent choice.
