installing derailleurs
 

I'm doing a "reverse conversion"! after riding my Salsa Casseroll fixed for a few years, I want to try it as a geared bike. I'm putting a Tiagara RD, Ultegra FD and Shimano bar end shifters on - all parts I picked up along the way. My question is which derailleur do I set up first? I've been looking uat different sites and videos on this, but not sure if it matters that I do either the FD or RD first. I'm a relative noob at this, but am fairly mechanically inclined. Any tips from any of you pros out there??:)

doesn't matter. you'll only adjust them after installing a chain.

adjust rear first

I like to get the rear set up first. That way you can easily shift across the whole cogset and check for chainrub when you're setting up the front.

Fail.

You have to adjust the rear first.

How else do you set the front derailleurs low limit or high limit if the chain doesn't even sit in those sprockets?
