Use this kit with your Sweetroll for four-point attachment to Jones Loop H-Bars, Surly Moloko Bars or similar. We really like using this kit as it eliminates the need to attach the Sweetroll to your bike's headtube. The Sweetroll can be used on Jones/Moloko bars without this kit but the additional stability, security and separation from the head tube are well worth the meager price of entry.
This kit is only compatible with the Sweetroll and is NOT COMPATIBLE with Revelate's Harness.
Give Revelate's blog post a read for a bit more information on installation and setup tips.
