In addition they have updated their support for the Intel APIC that is paving the way for ongoing work on multiprocessor support where their previous APIC driver couldn’t escape the single processor constraint of an original Intel 8259.Īside from these its new-found support for multiple monitors should delight more productive users, and its improved support for ISA plug-and-play cards will be of interest to retro enthusiasts. Sadly this doesn’t seem to mean that this now does the job of a 64-bit Windows API, but it should at least take advantage internally of the 64-bit processors. ReactOS has had 64-bit builds for a long time now, but it appears they’ve made some strides in both making them a lot more stable, and moving away from the MSVC compiler to GCC. Their most recent update has a few significant advances mentioned in it that hold the promise of it moving from curiosity to contender, so is definitely worth a second look. One we’ve casually kept an eye on for years is ReactOS, the long-running open-source Windows-compatible operating system that is doing its best to reach a stable Windows XP-like experience. It certainly has the performance of a top aero bike and the ability to be able to take wider tyres is a bonus for comfort.In the crowd of GNU/Linux and BSD users that throng our community, it’s easy to forget that those two families are not the only games in the open-source operating system town. Calipers sit on top of CNC'd aluminium Disc Cooler fins which reduce operating temperatures by up to 35%." Calipers are mounted on the chainstay for better dissipation of braking forces using the flat mount standard for a neat, flush fit. Cycling Weekly described it as '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'.Īll Reacto come with powerful hydraulic disc brakes. Small details such as integrating the front disc cooler behind the fork and the rear disc caliper in the rear triangle and creating new bolt through axles with the thread integrated into the fork dropout minimise drag and improve aerodynamic performance.Ī myriad of small improvements over-compensate for the aerodynamic compromises made to give the Reacto bigger tyres, resulting in the perfect package of comfort, aerodynamic, lightweight and style.Ī long string of test wins, perfect scores and awards confirm the successful evolution of the race-proven DNA of the previous model with the latest trends and technologies. The Reacto CF5 needs just 209 watts effort for 45 km/h speed, 1 watt faster than its predecessor so it's in the leading group of aero road bikes ever tested by TOUR magazine. Prototypes were wind tunnel tested following the German TOUR magazine standard, including the 'moving leg dummy' test. Computational Fluid Dynamics (CFD) calculations were used to model performance in a virtual wind tunnel, guiding the changes which offered the most aerodynamic benefit: In the world of Pro-Tour racing no area can be ignored. The 4th generation model is more slippery and beautiful than ever, incorporating wider tyres, much neater cockpit cable integration and a series of incremental improvements to boost performance. Merida says: "The Merida Reacto has always been a class leading aero bike, combining state of the art aerodynamics with rider comfort. What do the manufacturers say about it? How does that compare to your own feelings about the bike? Tell us what the bike is for and who it's aimed at. Real-world aero benefits, a great ride quality and a respectable price It's a very capable race bike that also does well on price. The Reacto 7000 is a high-performance bike that certainly highlights its aero design cues when you ask it to get a shift on, and the high level of stiffness means that it performs when you get out of the saddle too. The Venturi is also available for £4,599.99 with SRAM Rival eTap and deep-section wheels, but it's the Tailor Made Orro Venturi STC SRAM Force eTap model that includes an upgrade to a BLK TEC carbon fibre handlebar and stem for a little bit of extra bling.Ĭanyon's Aeroad CF SLX 7 also comes with an eTap Rival groupset and costs £4,799, but in addition to that it gets a swanky set of DT Swiss carbon wheels and a carbon cockpit. I rated the Orro Venturi STC Force eTap Tailor Made, which is a similar bike to the Reacto. The Giant's a few hundred grams lighter and comes with the same finishing kit level as the Merida. The Reacto 7000's £4,350 price makes it a lot cheaper than the £5,499 aero Giant Propel Advanced Pro 1 that Mat tested recently. Bike companies often sacrifice quality tyres when speccing road bikes, so it's impressive to see top-end rubber straight out of the factory.
