The new Polygon Bend FX4 is built for the urban rider that wants a fast, light and agile bike that will hold up to rough and tumble commuting duties with everything the rider needs to move through the city with ease.

The Bend FX4 starts features a lightweight hydroformed 6061 aluminium frame with 12mm front thru axle and Polygon’s Flex Stay technology on the rear which reduces road vibrations and keeps you comfortable on the bike for longer. 

If you were comparing this bike to the Polygon Path range of bikes, consider that the FX4 is more similar to a flat bar road bike, in terms of geometry and also performance. 
The bike has kept on trend with technology too, with the bike now featuring the latest flat mount disc brake standard.

With disc brakes all the braking forces go through the rotor, this means that the rim can be made much lighter and hence there are corresponding performance gains. 
Quality Schwalbe Kojak tyres feature on the bike too, these come with proprietary puncture protection and reflective labels. With only the tyres as the contact between the bike and the road, these serve a vital role in the ride feeling and how the bike performs. 

To emphasise the focus on speed, the FX4 is set up with lighter road bike componentry rather than mountain bike componentry. The 20 speed Shimano Tiagra 4700 gear set has features borrowed from the more premium groupsets in the Shimano range, are now lighter and more durable than ever before. The levers too, require less effort to shift and are smoother and more responsive.
