Reaction Pro: now we're getting down to business. With a completely reworked frame for 2018, new features like a Boost rear end and Stealth dropper post compatibility make the ideal foundation for our performance-orientated, all round hardtail. The spec list is bursting with high quality components that won't let you down. From the easy adjustability of the air sprung RockShox fork to the slick reliability of Shimano's 2x11 transmission, this is a bike that's crying out for some fast singletrack action. No compromise speed, comfort and control - now that's a combination you can get behind.
