New vs Old - Gamut USA showed us their new rollerless dual ring chainguide, shown on the left, next to the older Gamut Dual Ring guide on the right. The guide uses the same O-ring system as their P Series guides with a step to accommodate front ring shifting. They should be available soon and in a wide variety of sizes to handle all the different drivetrain options in the all-mountain and trail market. While this is a prototype, with bashguard, they're estimating a sub-100g weight.
