WTB: Cyclocross Parts

[Kebuchan24]

I am switching my cross bike to 1x10 which means I need a few things to finish the project. The things I am looking for are as followed:

- Chainring Guard (110 BCD) 5 bolt
*I am going to be running a 39T ring in the front but might switch to a different size ring later. So I think something around a size 42T guard would work.

- 10 Speed Sram Rear Derailleur
*I would like to have Force or Red but only if it is used. They don't have to be pretty either. This is a cross bike so they will get dirty and scratched at some point. Unfortunately I don't have the cash for that shiny NIB stuff like most people :P

- 10 Speed Sram Cassette 11-28
*Same deal as the rear derailleur. Looking for Force or Red but used and functional is preferable.

Thanks.
