Product information "OVAL GUIDE -ISCG05-38" Since oval chainrings are very trendy for many of you, we offer our Oval Guide the lightest fully adjustable chain guide on the market. The assembly is done in no time and without disassembling the crank. The chain is held securely in any position on the oval chainring. The CNC milled scale makes it easy to adjust to the chainring size and the adjustment of the chain lines is a breeze with the help of a table and spacers. The front flip technology allows you to remove the chain without tools in case of a breakdown on the trail, or pull the crank out of the bottom bracket during service without having to disassemble the chain guide. The versions marked with the 38 have a chainring adjustment range of 26-38 teeth covers.
