Advice for a newbie?willierides

Hi. My first post over here (I used to post quite regularly on the MTB Passion board).
After a lackluster season last year I'm rejuvenated to ride a lot more in the coming year. In addition to buying a decent mountain bike a few years ago, I've decided to build a decent road bike over the winter. I've been riding a Lotus that I bought at Sears about 10 years ago. Although I successfully converted it to a triple chain ring last year, it just doesn't fit me all that well and I've decided that I deserve a decent bike after all these years of riding junk.

So.....I have a new 2001 model Giant TCR 0 frame, fork and headset. I also have a set of wheels (700c, no cassette yet) and Tiagra STI shifters (nine speed, triple). I need to get brakes, cassette, chain, crank, bb, seat, seatpost, handlebars, stem and derailleurs and a kick stand....okay, kidding about the kickstand.

Are pretty much all derailleurs (Shimano) compatible with my Tiagra shifters? Can I mix and match Ultegra, Tiagra, 105 and Dura Ace as long as they're for 9-speed, triple application? I bought the Tiagras to put on my Lotus, but would like to use them on my new build. I want to go with AT LEAST 105 cranks and derailleurs now.

My frame is set up for a braze-on front I need to worry about top or bottom pull?

Also, what ta heck is "Octalink" and "Isis"? I guess as long as I make sure that I buy compatible cranks and bb I'm ok, but I'd like to know what they mean.

Well, that's a lot for a newbie to ask in their first post, but I'd appreciate any feedback, including general tips and advice on building my first quality road bike. I've always wrenched my own bikes and I'm really psyched to get going on this....meanwhile I'm stuck riding my old Lotus on my trainer and looking at my frame (which my wife won't let me touch until Christmas!) or heading out to the snowy trails on my mtn bike.

Okay, I'll stop now. Thanks in advance for any help!

AFAIK, any Shimano 9 speed derailleur will work with your Tiagra shifters. All road front derailleurs (from all manufacturers) are bottom-pull, no worries there. Octalink is Shimano's proprietary 8-spline interface, while ISIS is a 10-spline interface. There aren't many ISIS cranks and BBs for road bikes yet, but there are some excellent ones from FSA. Good luck w/your project, and have fun!

go at least with 105 shifters and save cash on other parts. in the end, the shifters are the interface between the user and a bike, and loads if not most of shifting performance depends on the shifters. Other than that, welcome to the dark side. Kick the sh¡t out of that tarmac!!
