Merida Reacto 4000 Carbon Road Bike In Grey/Silver

Season:2025

Brand:Merida

Code:P-Q070

Unadulterated aero road speed.

REACTO 4000 might be the most affordable aero bike in their range but is far from being an entry-level bike. Featuring a 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.

The latest version of the REACTO took the cycling press by storm. A long string of test wins, perfect scores and awards confirm their successful symbiosis of the race-proven DNA of the previous model with the latest trends and technologies. 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.
