Product details
Fast, quiet, and just plain cool. Looking essentially cable-less, Polygon’s Strattos X-series bikes are equipped with Shimano’s sleek electronic groupsets. Outfitted with 105 Di2, the S7X delivers precise shifts – even under load – and impressive stopping power, giving you high-end performance while still leaving you with a little money for that new jersey and helmet. Polygon’s light and rigid carbon Strattos frame is agile, efficient and UCI-approved. Specially engineered seat stays have a slight flex to help absorb road vibration. All of this tech is connected to the ground by Schwalbe One tires; with their low rolling resistance you get speed on the straights and subtle side wall cuts for grip in the corners.
- ACX carbon fibre frame has been engineered for improved power transfer with a downtube that 16% stiffer than previous generations
- Carbon fibre fork is rigid, light, and nimble.
- Custom engineered dynamic seat stays absorb vibrations, improving ride comfort without compromising power transfer.
- Frame and fork are UCI approved, if you’re feeling competitive.
- Shimano 105 Di2 2x12 drivetrain puts 24 gears at your fingertips, taking the edge off the hills and adding as much speed as you want
- Light touch shifting changes gears and keeps your hands firmly planted on the bars, no need to fully push the shifter like with a mechanical shifter
- Shimano’s electronic groupsets let you glide through the gears with a simple press-and-hold of your shifter, no need to worry about 1 or 2 shifts at a time
- Di2 shifting adjustments can be done quickly and easily on the free app, no need to mess with limit screws
- Shifter battery life of 3 years
- Derailleur battery life of approximately 1000km with easy USB-charging.
- LED battery status indicators let you check the battery level of both the derailleur and the shifter batteries
- Shimano 105 hydraulic disc brakes provide serious stopping power in even the worst weather.
- Schwalbe One tires are tubeless ready and use the durable, yet grippy Addix rubber compound.
- 28mm tires are a little fatter than average road tires and balance speed with comfort – with the emphasis on speed. Frame can fit up to 32mm tires.
- Internal brake cable routing looks great, reduces drag, and makes it easier to clean your bike after mucky rides
- Entity Flux2 short nose saddle promotes a natural rotation of the pelvis, improving stability and allowing you to maintain a comfortable cadence with less effort
- Bikes are covered by MEC's Rocksolid Guarantee and Bike Service Agreement. You can bring your bike to any MEC bike shop for free adjustments and minor maintenance for a year after purchase
- Based in Indonesia, Polygon has been making bikes for more than 25 years. Polygon makes all of their own frames in-house, allowing them to control the design and construction of their bikes from inception to shipping. You will find Polygons ridden in the Red Bull Rampage, UCI Downhill World Cup and other major mountain bike events all around the world.
- Due to challenges with supply chain, components may be substituted for comparable parts at any time. The listed build is how MEC intended your bike to arrive, though the manufacturer may need to make a tweak or two to get you riding sooner
