Just use a top guide and clutch rear mech, a Zee shadow + rear mech would suit you fine and if you are worried about dropping a chain then have a look at “absolute black” or “works components” front chainrings designed to run in a 1×10 system – there is no need for anyone to run top and bottom guides these days.
Hi.. I have a specialized stumpjumper fsr expert carbon 2010 model… I want to convert to single 1×10 setup.. the frame takes press fit bottom bracket so no iscg mounts or adapters fit the bb.. I know the e13 xcx guide can help the top but what about the bottom? what chain tensioner can I use?
