By substituting the saddle for one with carbon rails and switching the wheels to some lightweight DT-Swiss 38mm tubs, I dropped the complete bike weight, with Ultegra pedals to 7.00 Kg. Our size 54cm tips the Cycling Weekly scales at 7.54 kg without pedals. It appears to work, with the Reacto offering a commendably comfortable ride for such a stiff frame. Merida have found that inclusion of flax fibres in the carbon structure of the seat, chain stays and fork blades reduces high-frequency vibrations. The carbon layup also features natural flax fibres. The idea is that by allowing flex here, it does not compromise bottom bracket stiffness. The rubber insert is designed to compress and flex, taking the buzz out of the road. The added comfort is claimed to come from a number of technologies. The S5 has been critised in the past for having a harsh ride and this is a common flaw in aero road bikes. However they claim that the Reacto is a superior package owing to its much greater comfort and flex. Marginal gains! The FrameĪccording to Merida, the Reacto is marginally less aerodynamic than the Cervelo S5 at 45kph, 0.94% to be precise. For those amongst you who are not regular players of Countdown, that is 0.14 seconds per kilometre. Rotor claim that the Flow cranks can give a 26.4 second advantage when averaging 200W over 180km.
The Rotor Flow cranks suggest that no stone has been left unturned in the hope for aero gains. However, there is the option to add Q-rings to the Rotor cranks if you want to. The chainset is a Rotor Flow with NoQ, meaning that the rings are round and not ovalised. Merida says that the weight of the Reacto (rim brake) frame, fork, seatpost, seatpost clamp and headset has come down from 2,046g to 1,695.5g, and that the new version is more comfortable than before.īuy if: You’re after a no-nonsense urban commuter at a decent price.The compact rear triangle is striking and looks very stiff A one piece cockpit with integrated features has also been added. The aero improvement has been achieved by slimming down the tube shapes, introducing a lower seatstay/ seat tube connection and modifying the seatstays to have a larger bend towards the cassette. Merida also claims that the difference in aero efficiency between the rim brake and disc models is less than one watt at that speed. Merida says that the new Reacto is more aerodynamically efficient than the previous version by about eight watts at 45km/h. Read our story on the launch of the Merida Reacto. The Reacto is now available in both disc brake and rim brake models, each in two different geometries. The Scultura (above) has some aerodynamic features but it’s the Reacto that’s the real aero option in Merida’s road bike range, and the carbon fibre models had a major redesign for 2018.
The Scultura Disc 5000 is built up with a Shimano Ultegra (mechanical) groupset, including hydraulic disc brakes.īuy if: You want a performance-minded road bike and your focus is on light weight. It's built to a geometry that’s slightly more relaxed than that of the top-level Scultura Disc Team (£8,000) and the carbon fibre layup is different, but this is still very much a performance orientated bike featuring a down tube shaped for aerodynamic efficiency and aluminium disc cooling fins around the chainstay to shift heat away from the rear brake. The Merida Scultura Disc 6000 is no longer available but there's a Scultura Disc 5000 (above) at £2,200. Merida also offers a couple of Race entry-level aluminium road bikes.Īs well as drop bar Merida road bikes, we’ll also cover flat bar road bikes, cyclocross and hybrid bikes here. That perhaps oversimplifies things a little because each of those categories contains more than one frame design, but it’s a good start point. Let's take a look.Īs far as Merida road bikes are concerned, there are three main parts to the range: the Scultura is focused on light weight, the Reacto is engineered for aerodynamic efficiency, and the Silex is designed to offer plenty of comfort across a variety of different surfaces.
