Record 10 Steel?(5 posts)

I have a carbon fiber bike with the record 10 groupo, hubs and petals too. I wanted to know what parts are made of steel so i can prevent rust from forming by keeping a close eye on them.

If I'm not mistaken, the vast majority of the grouppo is aluminum (obviously what is not carbon fibre), which can oxidize if not kept clean. The only steel part in the group are the cassette cogs (if you have the steel cogs, you did not say), the bearings in the hubs, and the chain. This is all I can come up with. Can anyone else think of something I'm missing?

I think you have most of them, the way to find out is to take a magnet and run it over the surface of the parts, it sticks to anything steel.

The aluminum parts are anodized, which is an oxidation process; they are oxidized already!

The cogs are nickel plated along with the chain, so as long as you keep them reasonably lubed and don't scratch them up and leave them out in the rain they won't rust.

About the only things that can rust are the hub cones, washers, and lock nuts, and some attachment bolts. The bolts in the toughest environment are the brake lever clamp bolts - they see a lot of salt from sweaty hands. The brake mounting nuts see a lot of crud coming of the tires, especially if you ride in the wet. There are many other steel parts: brake bolts/nuts (but they are chromed) and springs (stainless or chromed). Brake bearing races are steel, but there is usually some lube around to keep them from rusting. The shifter internals have many steel parts, but that area is well-lubed.
