Replacement for Shimano C101 Front Derailluer

JayEInd · Dec 21, 2016

I have a Giant Cypress with a Shimano C101 front derailleur. The bike has three front chain rings and 7 rear cassette. The front derailleur has a great deal of play and so bad I'm afraid it's coming apart. I tried to order a replacement from Performance Bicycle, but they did not have anything that would work and sent me to Nashbar. Nashbar did have a replacement part, but it had to be back ordered. The ship date has been moved back several times since the original order. Can any one offer a suggestion as to a derailleur that would replace the C101 or another supplier that I might try? Thanks for any suggestions.

It may be the FD-A073. It's in the Shimano Tourney model group. It's only road triple for 7-speed I could find.

Chances are you can ditch that C 101 and replace it with a mountain bike front derailleur. It doesn't matter if your C 101 is the nasty E-type (attached to the bottom bracket). I've taken a number of E-types off bikes and replaced them with clamp-on front derailleurs.

Bring the bike to a shop whose owner or manager can think outside the box. Number of speeds don't matter much since cages can be slightly widened or narrowed if needed with some very basic tools.

Is it definitely the FD that is the problem? If you have the Suntour crank (48/38/28), as the current Cypress does, those chainrings are very prone to bending. I am UK based so I have no idea f these prices are good, but there are some inexpensive cranksets on here if your chainrings are bent.

Thanks All. JSR I ordered the FD AO73 from Universal Cycles, should have it next week. Riccardo that is the crank set I have, I just put a new one on two weeks ago. I don't know if it was bent, I replaced it because I had ran a chain too long and had to replace both the cassette and chain ring...........won't make that mistake again! The FD had seemed to me to have way too much play for some time so decided to change it out while I'm in the mood. Thanks everyone, I greatly appreciate all the advice. Jay

How did the FD-A073 work for you?

I also have a Giant Cypress. I've owned it for nearly 4 years and bought it off Craigslist. I've replaced pretty much all the components everything on it over time and wheels and learned a lot about bikes! I haven't touched the front of the drive train yet (derailleur, crank set, chain rings). I think about retiring this thing from time to time but it's been a dependable daily commuter (10 Km return) for me for a few years now.

Anyways, the front derailleur won't change to the small chain ring most of the time (I replaced the shifters and tried adjusting the H/L and also pulled apart the derailleur but I think the recoil spring is just toast or the thing is just overall tired. The large chain ring teeth have seen better days and shifting up there could be smoother... I'm thinking of replacing the crank set, chain rings and the derailleur. Anyone have a suggestion on cheapish crankset? I'm running a non-replaceable chainring crankset that is 28-38-48T w/ Shimano FC-C103 markings. I believe this is a square taper and cranks measure 170mm centre to centre.

Lastly... Is the only reason to replace the bottom bracket is if there is play? Sounds like the width can be different...

Cheers.
