I am putting a bike together and have it all apart but don't see the derailleur hanger anywhere. Did I lose it or did the bike not come with it? If it didn't come with it, why not?

Thanks.

If it came with a derailer one would expect it to come with the hanger. –  Daniel R Hicks Feb 27 at 1:36
    
(And how would you lose a hanger? Are you assembling this in tall grass?) –  Daniel R Hicks Feb 27 at 1:38
    
What year is this frame? –  alex Feb 28 at 1:40

1 Answer 1

The rear derailleur hanger on the Trinity was not replaceable, it was part of the frame and was there at the time of production.

2007 Giant Trinity A1

If there is no hanger on the end of the rear drop out then it has likely been either:

  • purposely removed (to make a single speed or fixie, possibly for track racing);

  • sheered off in a crash (or deformed and then removed); or

  • not an authentic Trinity frame.

All the Giant road bikes I've seen have the hanger attached by 3 very small hex screws. From Google images, this looks no different –  alex Feb 27 at 8:07
    
I'd think alex is probably right - you can find the hanger at your local giant dealer probably. –  Batman Feb 27 at 10:48

@Alex the Trinity was a TT bike not a road bike. It's also probable that someone would use it as a track bike as well so would remove the hanger.. Feel free to post an answer and vote mine down if you know otherwise. –  DWGKNZ Feb 27 at 17:40
    
@Batman assuming one was in fact available the best source of replacement hangers is wheels manufacturing, they machine replacement hangers for most big manufacturers. It is unlikely the a local dealer would hold a part for a 6 year old frame unless it was a mountain bike (which break and bend often). –  DWGKNZ Feb 27 at 17:46
