If you aggressively ride an IBIS Ripley V4, then I can't recommend this chainguide enough. Wow, the fit, the function, the size, the clever adjustment points. I would buy this again and recommend to all my friends. There is not very much room with the DW Links on this version of the Ripley and this guide is a perfect all mountain "keep the chain on" but not *overkill* guide. This guide bolts directly to the IBIS "bottom bracket spacer tab thinga-ma-jig" that is meant to mount guides to. Perfectly. I used the bigger spacer washers on my application and the chain is perfectly centered across the cassette range and does not rub anywhere. LOVE LOVE LOVE. Stop reading. Buy it. I'm serious. I have owned a ton of guides (I tried to get all of the old ones to fit this bike to no avail!) and this one is KING. Order now.
