With the SXg, MRP wants to deliver a guide without compromise and with no equal. MRP claims that the desire for protection and both upper and lower retention no longer have to come at the expense of weight, efficiency, or the addition of moving parts. Read more in the official press release.

The MRP SXG is supposed to be super versatile.

With the SXg covering all those bases, it’s the first guide in history that’s equally at home on anything from aggressive, short-travel bikes to Armageddon-ready Rampage rigs, and everywhere in-between. It’s a guide that refuses to be pigeon-holed, blurring the lines between typical industry definitions – a little country and a little rock, as they say. But, in this case, it’s whole lotta rock.

With only 106g for up to 34T, it is really light.

The SXg introduces a new revolution in drivetrain security – the Whippersnapper. As the name implies, the Whippersnapper lower guide halts the otherwise drop-inducing chain whiplash caused by deep compressions and successive hits. Ill-advised hucks to flat? Multi-story cliff drops? Ankle-deep bike park braking bumps? No problem.

It is supposed to handle all you throw at it.

Your choice of either an aluminum or carbon backplate provides the backbone of the SXg. Up top, you’ll find our new HD upper guide with co-molded TPU material on the interior walls and ceiling that silences chain contact. It’s attached via a tracked and grooved backplate interface that increases stiffness and eases installation. At bottom, the SXg skid provides safeguard to the chainring and glides over rocks and obstacles. Employing the same co-molding technology of the upper guide, the Whippersnapper uses nylon and a TPU material to provide durable protection from external blows and muted internal contact with the chain. Both the upper and lower elements of the guide feature our trademark Swingset pivoting hardware that makes installation and adjustment a snap.

Are you probably asking for too much?

So whether you’re a rider whose probably asking more-than-a-little too much of your short-travel trail bike, a racer that drops serious coin to race and wants to hedge against any possibility of a mechanical, or a thrill-seeking hucker who desperately needs their chain in its proper place while riding the thin line between death and glory – the SXg belongs to you.
