Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

What Front Derailleur

I have a 2004 Trek 1200 and the front derailleur broke. All I know is that I took off a tiagra derailleur. I just when off a whim and bought an ultegra replacement without thinking about it and now that its installed it seems pretty clear that it does not fit (granted the possibility that I installed it wrong is also on the table). I am trying to figure out what exact part I need but the internet isn't treating me so well. I would just like to put a part on it to sell the bike, so nothing fancy needed. Thanks!

P.s. if you want a new ultegra derailleur....

Are you triple? if yes than select 3x10 (works w/ 9spd) you need to know the tube size, you don't know...what size seatpost do you have? Its the next size up from that post size

Shimano clamp-on derailleurs often have the size stamped on the inside of the band (e.g., 31.8). Double vs. triple is a concern with both clamp and braze-on styles.

Do you still have the original FD? It might also say something like 'FD-4403' on there, which would really assist this forum in helping you out.

That bike is a triple, if you bought a new ultegra then its a double, now you have an excuse to swap the rest of the drivetrain!

Haha yes it is a triple, but no I can't afford to switch out the drivetrain!! (Great idea though!)

Thanks!

Something like this will work just fine:

wiggle.com.au | Shimano Tiagra 4603 Triple 10 Speed Front Derailleur | Derailleurs Front - Road

Just figure out whether you need a 31.8mm band on or a 34.9mm one.

The below is probably suitable, assuming you need a clamp-on 31.8 like my 2002 trek 2000
