At A Glance

When you open up the box for the P30 bash ring and chain guide you’ll be surprised to find there isn’t much in it. Simplicity is something that Gamut have gone for here and it certainly shows. The bash ring is machined to save on weight rather than being a solid lump. The machining has been done to direct energy from impact away from the more expensive bits of your drivetrain. This isn’t just some fancy plastic work! The guide itself is very easy to fit to the frame, ours was ISCG 05 mount and we had it on in about 5 minutes. We fitted the bash ring to an XT crankset and aside from the usual trauma of getting the old chain rings off it was a very simple job. Albeit one that needed a vice!

On The Trail

The Gamut set up is billed as being one of the lightest and most silent guides on the market. Light it certainly is 160 Grams is frankly ridiculous! Silent isn’t a word we would use but it is certainly quiet, after a couple of minutes you really don’t notice it. We’ve had the system on a 160mm travel bike that has been round Afan, Betsy Coed, the Peaks and Aston Hill for the last two months and we haven’t lost the chain or had any issues with it since it was fitted. Long-term durability only time will tell but for the moment it has stood up to all the abuse that has been thrown at it. We fully expect it to serve us well in the Alps in the next few months. We’ll keep you posted!


Stunning looks and crazy lightweight so far the Gamut has packed a real punch in terms of performance and hasn’t missed a beat yet.

His first mountain bike was a Trek 820, which he bought in 1990. It didn’t take him long to earn himself a trip to the hospital on it, and he’s never looked back since. These days he’s keeping it rubber side down, riding locally and overseas as much as possible.
