I have a Shimano FD-R453 front derailleur that needs replacing. 50t and bottom pull with a 31.8 clamp. There are three gears in the front and 9 gears in the back. Could somebody help me with getting something similar as they don't make these anymore.

    I did a quick search for Shimano 453 and 450 series. There was a 6 speed MTB group but no 9 speed. Can you check the group set series and provide us either the name? Was this road or MTB? Aprox how old is the bike? Jan 22, 2019 at 22:21
  • Road Bike (Specialized). The Bike is 7 years old, and bought it new. Seems like they had a lot of trouble with the FD-R453.

Looks like The FD-R453 is a non-series (i.e. it does not get the 'Tiagra', '105' etc label) component. I believe it's roughly equivalent to Tiagra in quality though.

Any Shimano 3x9 front derailleur is going to work, Tiagra 4500 series - which is not current but is probably available, Sora 3400 or 3500 series also. The Sora FD-3030-B looks right.

  • @jimmyg. Sora is Shimano's dedicated 9-speed groupset. For a triple front the latest selections are FD-3503, FD-3403, FD-3030. The 3030 mech is designed for a 50t chainwheel. Thought I'd offer that as you referenced "50t" in your question, which i assumed that to mean what you have now.
