This is a pre-loved Polygon Tambora G4 in White, size XL: a 700c aluminium gravel bike with a carbon fork, Microshift Advent X 1×10 gearing and Tektro mechanical disc brakes. Polygon built the Tambora for everything from gravel racing to bike-packing, with thru-axles front and rear, internal cable routing, mounts for bottle cages, racks and mudguards, and room for 45 mm tyres.

Every pre-loved bike we sell is inspected and prepared by our Dubai workshop and leaves with a three-month Bikeera warranty. Ask us for current photos of this exact bike, or come and see it at our shop on Umm Suqeim Street.

Before you buy

  • One frame size, XL: for riders about 188–196 cm tall. Check the geometry below.
  • Used condition: this is a second-hand bike. Photos on this page show the model; message us for photos of this one.
  • Wide-range 1x gearing: a single 40T chainring with an 11–48T cassette, one shifter to think about.
  • Ready for bags and mudguards: rack, mudguard and bottle mounts on the frame.

What makes it work

Microshift Advent X rear derailleur on the Polygon Tambora G4

Microshift Advent X 1×10

A 40T chainring and an 11–48T cassette give a low climbing gear for steep gravel and enough top end for the road, with no front derailleur to maintain.

Microshift Advent X shift-brake lever on the Polygon Tambora G4

Flared drop bar

A 16° flared alloy bar gives more control on loose surfaces, with the Advent X shift-brake levers on the hoods.

Carbon fork and Tektro disc brake on the Polygon Tambora G4

Carbon fork, thru-axles

A carbon rigid fork with 12 mm thru-axles front and rear keeps the bike stiff and precise; Tektro MD-C550 mechanical discs on 160 mm rotors.

Tyre clearance on the Polygon Tambora G4

Room for 45 mm tyres

Fitted with Vee Tire Rail Frenzy 700×40 tyres on 23 mm (internal) double-wall rims, both tubeless compatible, with clearance up to 45 mm.
