As with all VeloSolo products the Disc Cog is custom manufactured in England by the UK's leading international aftermarket motorcycle gear and sprocket engineering company with over 70 world champions riding its products.

Blanks are machined from EN36 cro-moly steel stock, teeth precision milled and cogs drilled to very tight tolerances before undergoing heat treatment. Bright nickel passivated and laser engraved for a beautiful finish. Very strong, very round and a perfect fit. Not to be confused with cheap laser cut or stamped cogs. Reversible without affecting chainline for even longer life.
