Just recently more manufacturers have released their lightweight 520 steel rear sprockets. These are all about 1 pound more then a hard anodized alum rear sprocket. They use to be much heavier, but using certain techniques more weight has been reduced.

We now have a selection of the Driven Evo-Spec steel chain kits, the Drive systems superlight steel chain kits, and the Vortex lightweight steel chain kits. They all have their own unique design, but one other thing that is harder to see from the pictures is that the Driven and Drive Systems rear sprockets are a standard black where the Vortex is more of a matte black rear sprocket.

All of these kits are available with our wide selection of high end chains that all come with a rivet master link.

Hey Corey, I didn't them listed on your site, but which vendors do you carry Marchesini rear sprockets for? is that an additional charge when you order?

My current driveline should last the rest of the season, but I'll probably start fresh in spring.

Driven for hard anodized alum. Just order the kit for your bike and in the customer notes section of the order put "marchesini rear sprocket needed" and we'll get it for you. In this steel nobody does them for marchesini's though. So it would be the hard anodized alum Driven chain kit. We have most all of them in stock for the Marchesini rims as well.

Thanks :)

If you just want the rear sprocket there is a drop down on the Driven rear sprocket product to pick a marchesini instead of a bike. but if you want the whole kit just do what I said above and this way you get the full chain kit discount for buying it all as a kit.

Yeah, I've been working with the 530 setup the March's came with since I got them. I'll be switching everything over to 520.

If you want a SUPER long lasting set up get the ek zzz chain. Longest wear indicator life and strongest 520 chain on the market right now.

As long as is lighter than my stock setup, the kit will be on my Christmas list..

It will be much lighter then your oem 525 set up and last just as long if not longer as the products are much better.
