It also features laser etching to aid in setup and identify which mounting standard you are holding in your hands.

Developed by request from OEM customers, the G2 Steel uses the same polycarbonate parts from the existing mini G2 Alloy series and combines them with a steel backplate in order to offer a lower price point that performs exactly the same as the top-end alloy guides. Our plan is to offer the mini G2 Steel in ISCG and ISCG-05 models, but not with BB-mount. You will see this guide specified on several global bike brands for the 2011 model year.
