SRAM’s G2 brakes feel and look a lot like its proven Guide units but an entirely new caliper and detail changes throughout the design improve already excellent feel on the trail.
SRAM has always set the standard for easy installation and the G2’s ambidextrous levers bolt straight into the existing ‘Matchmaker’ synced shifter mount system. Leak-free connectors mean cutting pipes to thread through frames or get rid of excess length can often be done bleed free. If you do have to flush the system then the ‘bleeding edge’ circuit makes complete bubble removal blissfully easy and SRAM’s screw-in syringes are particularly nice to use. New hoses are even designed to reduce weird kinks and twists as you screw things into place so the installation is likely to look neater.
The cup-and-cone CPS angle adjuster washers that used to make setting up SRAM brakes a jaw clenching juggling act have been quietly forgotten and more consistent pad pullback makes scuff less likely when setting up. In short, you won’t find an easier brake to install on your bike.
SRAM brakes have always felt good (at least when new) under the fingers thanks to a close-to-bar pivot point. G2 improves on that with new bushings on the ‘cheaper’ RSC levers so there’s less slop and rattle from the forged alloy blades over time. Ultimate’s still get cartridge bearing pivots and carbon blades for a silky feel and warm winter fingers. Either way, the bite point adjuster dial feels crisper and clickier on G2 and the return feels faster and lighter thanks to improved piston seals at the caliper end. The caliper is all-new too. It’s still two pieces bolted together but it’s stiffer for a boost-in bite and the existing resin and sintered pad options have been joined by a new resin ‘Power’ pad.
Together SRAM says this adds up to a seven per cent power increase to keep it in line with ever-faster trail bike speeds. The most noticeable difference though is a crisper, better communicated feel all round, keeping heart rate reasonable even in the sketchiest, slipperiest, turn in or wipe out moments. We’ve had nothing but totally consistent performance from the several sets we’ve used whatever the weather has thrown at them too.
G2 has taken an already excellent benchmark trail brake and made it slightly better all the way through from stress-free installation to traction communication and braking control in the most mental moments. They stay that way whatever the weather or length of the descent too, making them a genuine fit or forget brake.
They are expensive though - particularly if you opt for the 15g lighter carbon and Ti trim Ultimate option. They also face serious competition from SRAM’s own Code brake which offers significantly more power for even more relaxed control and doesn’t weigh much more either.
