Polygon has expanded its all-road lineup with a new Strattos series that pushes carbon-frame, electronic-shifting bikes well below the £2,200 mark — a price band where the competition is overwhelmingly aluminum and mechanical. The Indonesian-built brand confirmed the launch this week, undercutting most of its big-brand rivals by a substantial margin.
What Polygon Just Launched
The new Strattos arrives in four builds, anchored by a redesigned ACX carbon frameset with clearance for 34mm tyres and full internal cable routing. The range starts at €1,599 (~£1,400) for the Strattos 6 with Shimano’s latest 11-speed Tiagra mechanical groupset, climbs through the 105 mechanical 7 and 105 Di2 7 Di2, and tops out at €2,999 (~£2,600) for the 8 Di2, which runs Shimano Ultegra Di2 with a fully wireless cockpit.
Sitting above the Strattos sits the all-new Strattos C — a premium carbon range Polygon launched in parallel. The Strattos C7 Di2 starts at $2,900/€3,300 with Shimano 105 Di2, the LINC integrated carbon cockpit and Polygon’s own WR4 carbon wheels (40mm deep, 21mm internal, tubeless-ready). The C9 AXS pairs SRAM Force AXS with the same chassis and lighter wheelset.
Polygon is positioning the Strattos as an “endurance-leaning all-road” platform — slightly more relaxed geometry than its race-oriented Helios, room for fast 32–34mm rubber, and full mounts for fenders and a rear rack on the alloy-fork models.
Why It Matters
Carbon plus electronic shifting under £2,200 has been the white whale of road cycling for years. Until very recently, electronic groupsets were locked behind £3,000+ price tags, and the few carbon Tiagra/105-mechanical bikes that existed almost never moved up to Di2 without a major price jump. The arrival of Shimano 105 Di2 R7100 in 2022 cracked that ceiling at the component level, but most major brands — Specialized, Trek, Cannondale, Giant — have kept their carbon Di2 builds north of $3,000.
Polygon’s pricing is significant for two reasons. First, it’s a direct shot at the value-carbon segment owned recently by direct-to-consumer brands like Canyon and YT. Second, it lowers the entry point for cyclists who want the long-term reliability of Di2 (no cable stretch, smoother shifts, lighter lever effort) without paying nearly twice as much for it. Polygon’s parent company manufactures bikes for several major brands, which is part of how the price stays competitive.
The 34mm tyre clearance also matters. The all-road category has effectively absorbed what used to be called “endurance road,” and most riders now expect to fit 32mm or wider tyres for comfort and rough-pavement capability. Many older “endurance” bikes top out at 30mm — the Strattos doesn’t.
How It Compares
At €2,999, the Strattos 8 Di2 sits at roughly half the price of a Specialized Roubaix Comp or Trek Domane SL 6 with comparable Ultegra Di2 spec. A Canyon Endurace CF 8 Di2 — the obvious direct-to-consumer benchmark — comes in around €3,499. The Strattos C7 Di2, at $2,900, is competitive with the State Bicycle All-Road carbon and the Ribble Endurance SL Disc, both of which have built reputations as carbon-Di2 value plays.
The catch, as always with Polygon’s value pricing, is dealer availability — the brand’s North American distribution is thinner than the European-direct flow, and U.S. customers will mostly see the Strattos via Bicycles Online or specialist Polygon dealers. UK and EU buyers will find broader dealer support.
What This Means For You
If you’re shopping for an upgrade-friendly first carbon bike — or replacing an older alloy commuter that you’ve outgrown — the Strattos sits squarely in the “buy once, ride for a decade” zone. A few practical pointers:
- Pick the Di2 build if you can stretch the budget. Shimano 105 Di2 has been hugely reliable since launch, holds resale value better than mechanical, and is upgradeable to Ultegra Di2 by swapping shifters and derailleurs without changing batteries or wires.
- Check the tyre spec at the dealer. Polygon ships the Strattos with 30mm Schwalbe One Addix TLE tubeless-ready tyres on most models, but the frame can fit much wider rubber. If you ride rough roads or unpaved sections, ask the dealer to swap to 32–34mm before delivery — it’s the single biggest comfort upgrade you can make.
- Don’t skip a proper bike fit. Endurance geometry is more upright than race geometry but still rewards a fitting session, especially on saddle setback and stem length. Plan for £80–£150 on a fit after delivery.
If you’ve never ridden electronic shifting before, the difference is more about consistency than speed — the front shift in particular doesn’t drift out of trim the way mechanical front derailleurs do, and that alone is worth the upgrade for most riders.

Where the All-Road Category Is Headed
Polygon is the latest sign that the all-road bike — the “one bike to do it all” segment that started squeezing pure endurance road and slow gravel together — is becoming the default road bike for riders who aren’t actively racing. Recent launches like the State All-Road V2 and the BMC Teammachine 01 AMP have pulled in the same direction: room for wider tyres, more comfort-focused geometry, and price points designed to convert riders who would once have bought aluminum entry-level bikes.
The category’s gravity is pulling the rest of the market with it. Even pure race bikes like the new Giant Propel 2026 and the Cannondale SuperSix EVO 2026 now ship with 32mm tyre clearance as standard. The argument that “all-road” is just “modern road” is harder to dismiss with every quarter that passes.
Key Takeaways
- Polygon’s new Strattos lineup brings carbon-frame, electronic-shifting road bikes to under £2,200 — a price band that’s almost universally aluminum or mechanical elsewhere.
- Range tops out at the Strattos 8 Di2 (€2,999, Ultegra Di2) and the premium Strattos C9 AXS (SRAM Force AXS).
- Frame fits 34mm tyres, supports fenders and a rack on alloy-fork builds, and uses Shimano’s latest electronic platforms.
- The launch is part of a broader move that’s flattening the line between “endurance road” and “all-road,” with race-bike clearance numbers catching up fast.
- Best value play is the Strattos 7 Di2 — Shimano 105 Di2, full carbon, room to grow into wider tyres or upgrade groupsets later.
