Merida Reacto 4000
Our REACTO 4000 might be the most affordable aero bike in our range but is far from being an entry-level bike. Featuring our lightweight CF3 frame with race-proven geometry, the 4000 offers impressive comfort due to the generous tyre clearance (up to 30 mm tyres) and the fitted S-FLEX carbon seat post. At the same time, the latest super smooth mechanical 12-speed Shimano 105 groupset keeps shifting in braking and perfect check. This is the ideal aero bike for your first steps into the racing world as well as challenging club rides.
Unadulterated aero road speed. The latest version of the REACTO took the cycling press by storm. A long string of test wins, perfect scores and awards confirm our successful symbiosis of the race-proven DNA of the previous model with the latest trends and technologies. Cycling Weekly calls it 'without doubt one of the most complete bikes available on the market', Cyclingnews 'an utterly brilliant and faultless machine' and Cycling Plus were 'hugely impressed'. From serious racer via enthusiast to the ambitious road rider, the REACTO is a great bike for many people. Its outstanding aerodynamic performance, reduced weight, sharp handling and super quick acceleration makes it the perfect bike for criterium racers and sprinters. At the same time, the class-leading comfort gives it the ability to play out its aerodynamic advantage also on the cobblestones – or the idyllic but potholed littered lanes of your favourite training ride.
