Braze-On vs. Clamp FD?

I ordered a Ultegra FD and I guess it's a braze-on. I really didn't even know there was anything else. Now, I do know :)

Should I have gotten a clamp instead? I'm riding a Blue RD-1, carbon frame/fork.

If your bike doesn't have the braze for it (looks to have a clamp-on FD) you can order an adapter that clamps onto your seattube and the FD clamps to that. http://www.bikeman.com/Braze-On_Adaptor_Clamps.html

Is it more worthwhile for me to just return it and get the clamp model? The clamp was $10 cheaper than the braze-on.

If you can, I'd return it and get the correct one. Be sure to make sure the size is correct; there are different clamp diameters for different seat tubes.

Man, I feel completely and totally inept.

So, this is my bike. www.rideblue.com RD-1. It says the FD is FSA Energy Band Mount 34.9.

So, okay, I need a 34.9.

So, I'm trying to order this. http://www.performancebike.com/webap...00_20000_65500

And it gives me two different drop down options? 1 1/4? 1 3/8? What the hell do I need?

I wish I knew more :(

You need the 1 3/8", which equals 34.9 mm. To convert from inches to millimeters, multiply the number of inches by 25.4.

thanks for everyone's help!

Depending on your situation, you could keep it and get the adapter. I intentionally did this because I have multiple bikes- some braze-on, some clamp on. By getting the braze-on FD, I can swap it out to a different bike if I need to - I move components around a lot. :)
