Has anyone tried the Terracycle Idlers? What are your reactions? I have a 2005 Screamer and want to make some improvements to the chain handling. There are a couple of easy modifications I can do using the stock idlers and new mounts but the concept of the toothed chain ring style of the Terrcylce idlers intrigues me. They are quite pricey so I wanted to get a reaction from anyone who has used them particularly on Rans bikes since the geometry and setup would be similar to mine.
