The February edition of Cycling Plus is out now!

The February edition of Cycling Plus is out now!

As road bike technology has changed in the last several years, so too has the idea of what a road bike is. The advent of the road disc brake has allowed designers to fit wider, tubeless tyres, while suspension and the way carbon fibre is manipulated means lightweight frames can be enjoyed on the roughest farm tracks. With that in mind, the six bikes in our main group test explore the new capabilities in the road bike market, all offering comfort and control-boosting, ride-expanding, puncture-saving, weather-beating advantages while still being fast enough to be properly flat-out fun. Elsewhere, senior technical editor Warren Rossiter fulfils a lifetime ambition of riding a custom-built titanium bike, collaborating with US Ti frame builder Lynskey on its Helix model. We’ve also got First Ride reviews of the Colnago Concept, Kinesis Aithein EVO, Canyon Inflite CF SLX 9.0 and Calibre Lost Lad, while the Cube Attain ...

SRAM Guide RS S4 MTB disc brake review

SRAM Guide RS S4 MTB disc brake review

SRAM’s imminently upgraded mid-range Guide RS brake is a great mix of practical performance and price without adding excessive costs for materials. Ultimate technology trickled down to SRAM’s Guide brakes While the Guide R is cheaper and looks very similar it lacks the internal ‘SwingLink’ cam that gives more clearance between the pads and rotor for quieter dirty weather running without reducing power or modulation at the contact point. You don’t get the bite-point adjustment dial of the Guide RSC, but you do get a tool-free reach-adjustment dial, and we found the default engagement setting to be spot-on for most members of our testing team. The distinctive arc of the broad blade lever amplifies average power in practical terms and it always feels pokey enough for challenging trails with a 180mm rotor. The big news is that from June 2016 all Guide brakes get the same all-new S4 calliper as ...

Ultimate technology trickled down to SRAM’s Guide brakes

Ultimate technology trickled down to SRAM’s Guide brakes

We’ve been big fans of SRAM’s Guide Ultimate brake. There’s plenty of power, loads of modulation and the lever is highly adjustable. The thing that really set it apart from the rest of the range was the Ultimate specific S4 caliper, which used a number of tricks to improve heat management and consistency over the standard item. The good news is that SRAM has now trickled down this technology to the rest of the Guide range. That means that even on the £112 / $133 Guide R, you’ll now get the same steel heat shield, insulated pistons and enlarged pad pocket to help keep things cool. Another welcome feature is that the caliper now uses the Bleeding Edge design, which has a special sealing bleed syringe to try and prevent air from being introduced into the brake when connecting or disconnecting it.The caliper also has different internal porting to help ...
