The Reverse Components single-speed conversion kit allows you to convert your conventional hub with a Shimano freewheel body to a single-speed drive.
Thanks to the seven different spacers, the cog can be optimally positioned on the freewheel body to guarantee a straight chain line. The Reverse single speed cog comes with an extra wide flange of 7 mm, which improves the power transmission gently to the freewheel body. The common width of the flange is only 2.8 mm, which can cut into the softer aluminium freewheels easily, which can lead to permanent damage to freewheel body! The 7 mm width Reverse Cog reduces this possibility. Other cog sizes (13-18 and 20 teeth) are available separately!

The product was already use !! You can tell but looking at the single speed kit =scratch marks and secondly it didn't come in its original packaging but in a previous handlebars backing. So what the point of paying for a product and you get a second hand product. And for the shipping you pay for 24h shipping. You phone them and they say we can, we can contact the shipping company or give a gift card of 3 euros. But with the disappointment of the product. I didn't bother to write a email to them.
