I have future questions on my build, I plan on getting the SRAM S300 from your site scrod, and it said that it was a 3/32inch chainring, and my current cog is 1/8th I believe, I'll have it checked out when I get a chance, I was wondering if I could use a 1/8th inch chain and be fine? Another question on that is will the MKS GR-9 work on the crank arms? are they the same thread size?

AND this is probably stupid but I have a spare rear brake caliper from my kilo and was wondering if it could work as a front caliper? they look the same, but I thought id get some clarification first rather than put it on and have it fail on me when i need it most.

I'll probably have more questions later on but, I'm still debating on parts to buy for my leader 725
