Indonesian bike brand Polygon has added a new Strattos all-road bike to its line-up, aiming to bring carbon frame technology, Shimano electronic groupsets and 34mm tyre clearance to a “sharper price point”. It’s offered in four builds, starting at €1,599 (~£1,400) with new 11-speed Shimano Tiagra and topping out at €2,999 (~£2,600) with Ultegra Di2, continuing the brand’s approach of trying to bring customers plenty of value for money.

Polygon’s new endurance-focused Strattos replaces the outgoing Strattos S Carbon and draws inspiration from the more premium Strattos C model. It’s available in four builds, with both mechanical and electronic Shimano groupset options. The entry-level model – the Strattos 6 – is the first complete bike we’ve seen to feature Shimano’s latest 11-speed Tiagra groupset.

“The new Polygon Strattos brings endurance DNA of the flagship Strattos C, whilst combining Polygon’s ACX carbon frame technology, Shimano electronic groupsets and 34c tyre clearance to a sharper price point”, says Polygon.

Visually, it’s very similar to the Strattos C, with uniquely shaped dropped seatstays and a taller stack height. The key differences lie in the frame’s layup, with the Strattos using the brand’s ACX carbon construction.

Like the Strattos C, the new Strattos offers clearance for tyres up to 34mm, and comes fitted with Schwalbe One Addix TLE 30mm tubeless-ready tyres as standard. Aero road bikes like the Cervélo S5 now accommodate similar widths, while endurance models such as the Lauf Úthald and Ribble Allroad SL can take up to 35mm of rubber.

Up front, all models use the Polygon Expert alloy cockpit, with internally routed cables, to keep things tidy, as well as Polygon RD6 Disc alloy wheels. The frame is also UDH compatible for future drivetrain upgrades.

Stock component choices are often not well suited to smaller riders and women, which can lead to added expense when buying a new bike. Polygon looks to address that with the Strattos, which is available in seven frame sizes from XXS to XXL, with size-specific components to match.

Each size is paired with well considered crank lengths – 165mm on XXS to S, 170mm on M and L, and 172.5mm on XL to XXL – alongside proportionate handlebar widths (380mm on XXS to S, 400mm on M and L, and 420mm on XL and XXL), aiming to deliver a better fit straight out of the box.

Claimed weights are 8.8kg for both the Strattos 7 and 7 Di2, dropping slightly to 8.7kg for the range-topping 8 Di2.

Pricing and availability

The range is available with both mechanical and electronic shifting options. The entry-level 6 model comes equipped with Shimano’s latest-generation Tiagra groupset, the 7 model comes with Shimano 105 mechanical, while there are two electronic builds: the 7 Di2, featuring Shimano 105 Di2, and the top-spec 8 Di2, using Shimano’s Ultegra Di2 groupset.

Prices start at €1,599 (~£1,400) for the 6 model, going up to €1,999 (~£1,730) for the 7 and €2,449 (~£2,120) for the 7 Di2, with the range-topping 8 Di2 priced at €2,999 (~£2,600).

For comparison, Ribble’s Allroad SL with Ultegra Di2 has an RRP of £3,099, which is already priced lower than the vast majority of the competition.

The new Strattos also sits at €1,000 below the premium Strattos C8, which features Ultegra Di2 and is priced at €3,999, while the C7 comes in at €3,499 with Shimano 105 Di2.

Are Polygon’s new budget performance bikes the real deal? We’ve asked for a test bike, so hopefully we’ll be able to review one later in the year.
