The Polygon XC Trail series was designed to ride a little bit of everything, from exploring back country single track to doing laps at your local trail centre. These bikes excel at charging technical climbs, pedalling through rough terrain, and pumping flow trails. The Polygon XC Trail series was built for anyone who spends all day on their bike tackling technical climbs and challenging descents.
Frames have evolved with the advancement of building materials and components. With these advancements, riders are having more confident riding, steeper, and more technical trails. FWG frame geometry has been adjusted to be more suitable to a more aggressive riding style, top tubes have become longer and seat tubes have become shorter. FWG frame puts the riders in a more neutral position and allows them to attack even on the steepest trails.
The modern trail bike is a jack of all trades. T-PRO bikes will make any rider feel like a pro by making the climbs easier and the descents smoother. Everything from geometry to frame material to components were taken into consideration with the T-PRO bikes. Adventure? Excitement? the T-PRO bikes are ready, willing and able. A one-piece linkage increases stiffness and decreases weight. Being efficient and effective is what one-piece linkage is all about.
2HRU allows riders to switch from a thru-axle to a quick release without major frame changes. With hub standards and frame standards constantly changing; 2HRU makes it possible to use your favourite wheel-set with your favourite Polygon.

* Mountain bikes are sized differently to road bikes. Typically, they are sized in inches as the first MTBs were produced in the USA. European brands like Lapierre and Haibike like to use centimetres for all their bikes. The measurements of their mountain bikes doesn’t match their road bikes but are like a simple conversion from the inches measurement. This is why we have included cm measurements in brackets for the Mountain bike column.
Read our bike size guide for more information on sizing.
