Quicker and faster engagement is what race hubs are all about these days. There are a few instant engagement models on the market today that work great; but they are expensive! With Crupi's all new Quad hub, we have an alternative which is very similar to instant engagement - but without the higher cost!
The Quad Hubs feature 150 ratchet teeth which engage every 2.4 degrees so what you get it s much faster engaging hub and nearly impossible to tell that it is not instant engagement!
We still provide 4 cog spacers which allow you to position the cog where it provides the best possible chain alignment. Hubset comes with a 16t cog but is designed to work with any Shimano compatible cog and any Shimano type tool will remove the cog.
