A secure, silent device that works well and looks good

Keeping a bike versatile without compromising performance is a big task, but Gamut have stepped up to the task with the P30 dual chainguide.

Gamut use a 6061 aluminium back plate that can be mounted to just about any bike (ISCG, ISCG 05 or bottom bracket) with a roller fixed on the underside of the ring to provide tension.

The polycarbonate bashguard ensures your chainrings remain intact and fend off any possible damage from stray debris on the trail. The device is a piece of cake to fit and just as easy to set up. With no top guide, the front mech remains undisturbed and can go about its business as usual.

The stepped roller helps maintain tension no matter what ring you’re using and shifting remains remarkably smooth throughout. We had no issues with dropping the chain, even after throwing some of the nastiest compressions and terrain at it – a good piece of kit.

Rob Weaver is BikeRadar's technical editor-in-chief. Rob manages all of the testing here at BikeRadar and across our magazines, Mountain Biking UK and Cycling Plus. Rob first graced the pages of MBUK back in 2001 when working as a freelance writer and went on to start testing bikes for the title in 2007. In 2010 he joined the team full-time and has been keeping a close eye on all things test-related ever since. Rob’s expansive knowledge of bikes comes courtesy of his passion for racing. He cut his teeth racing cross-country mountain bikes in the early 90s before finding his feet in downhill. After many years competing on the UK national circuit (including a year attempting to race UCI DH World Cups), Rob realised his know-how and passion for bike setup, tech and writing clearly outweighed his racing ability. A degree in sports technology and decades of riding experience all help to give Rob a thorough understanding of what’s needed to create a great bike or product. While Rob’s a mountain biker at heart and never happier than when he’s sliding down a Welsh hillside, he’s more than happy to put the miles in on the road or gravel bike, too.
