Re: [RBW] Front derailleur options for 38/24 front, 11-36 rear?

[Patrick Moore]

It just occurred to me that I can use a good FD that still has the outer
throw limit arm -- the extension of the parallelogram that contacts the
bottom of the outer limit screw; I cut off that on my 7400 when using it
with a Silver triple -- the throw was just right sans stop to get the chain
onto the 46 t ring -- and ditto for the 7402, to get *that* one to work
with a wide-Q (172 mm IIRC) Bontrager Race Lite pipe spindle external
bearing triple. That too serendipitously worked perfectly without any
except design limit to its outer throw. But I should replace the 7402 with
the 7400 on the Matthews because with 158 mm Logic (triple converted to
double) there is far more throw on the 7402 than needed -- whence a
"manual" stop when I shift -- while the design limit on the 7400 ought to
be just right for this Logic.

I don't see the latter listing (auction had closed when I looked) but I'll
honor my commitment; the various other DA FDs that popped up were in tht
$40 to $60 range, which I don't mind paying. And I'm 9/10 convinced that

 It might, since with such a small outer cog the chain will be closer to
 the chainstay and bottom of the FD cage than with a bigger outer like a 13
 or 14. Whether this makes a difference in your case, I cannot say for sure,
 but again I'd *guess* that, since you will be using the 11 only with
 the 38, this won't matter.

 There's also the matter of a wider cassette and chain rub on the
 derailleur cage. Is your cassette 11 speed or more? If so, I can't speak to
 that, but the wider the change in chain angle and the narrower the FD cage
 (as, for a 1st-gen DA road FD for 5 o 6 speed freewheels) the more chance
 of chain rub on the extreme outside and inside cogs unless you trim the FD.
 For me, I use my DA 7402 (I am pretty sure) FD with a 10 sp cassette and
 when I set the FD "in the middle" of its range there is no chain rub either
 in small or big cogs, and I think there's still futher leeway for chain
 angle without rubbing.

 Also affecting chain angle is chainstay length, but as this the RBW
 list and not rec.bicycles.tech or Cat.6.fredlist, I'd guess that will not
 be a problem for you.

That is extremely generous of you, Patrick, wow! I will then order this

 Fargo for a 2X9. The 3X7 consisted of 46/36/24 rings pulling (iirc) a 
 15-24 
 7sp cassette, and I swapped that out for a 38/24 X something-like 13-26 9 
 speed (29 1/2" Schwalbe Big Apples, then ditto Big Ones).

 The derailleurs were both LX of the period. When I converted the 
 chainrings I simply swapped the 46 outer for a (BBG) bashguard, swapped 
 the 
 36 for a 38, and adjusted the FD throw limit screw. I did *not* change 
 the position of the FD on the seat tube. After all, the FD shifted the 
 36/24 properly in that position, and it's not surprising that it shifted 
 the 38/24 properly in the same position.

 Later I swapped the LX FD for an ancient Dura Ace FD which I did mount 
 a bit lower, but for the bottom of the cage to clear the chainstay as well 
 as for the lower edge of the cage to clear the (IIRC, 48 t-size) bash 
 guard, the FD had to be placed much where it would have been placed for a 
 46/36/24. The DA FD worked just as well as the LX. Again, 38/24 X 15-24 
 (or 
 close) drivetrain.

 Nowadays, I have a 44/28 wide-range "subcompact" setup and the same DA 
 FD positioned high enough above the 44 to 

Re: [RBW] Front derailleur options for 38/24 front, 11-36 rear?

[Patrick Moore]

Forgot to address one of your questions: * Does me running 11-36 cassette
have anything to do with the front derailleur choice?*

It might, since with such a small outer cog the chain will be closer to the
chainstay and bottom of the FD cage than with a bigger outer like a 13 or
14. Whether this makes a difference in your case, I cannot say for sure,
but again I'd *guess* that, since you will be using the 11 only with the
38, this won't matter.

There's also the matter of a wider cassette and chain rub on the derailleur
cage. Is your cassette 11 speed or more? If so, I can't speak to that, but
the wider the change in chain angle and the narrower the FD cage (as, for a
1st-gen DA road FD for 5 o 6 speed freewheels) the more chance of chain rub
on the extreme outside and inside cogs unless you trim the FD. For me, I
use my DA 7402 (I am pretty sure) FD with a 10 sp cassette and when I set
the FD "in the middle" of its range there is no chain rub either in small
or big cogs, and I think there's still futher leeway for chain angle
without rubbing.

Also affecting chain angle is chainstay length, but as this the RBW list
and not rec.bicycles.tech or Cat.6.fredlist, I'd guess that will not be a
problem for you.

Re: [RBW] Front derailleur options for 38/24 front, 11-36 rear?

[Patrick Moore]

I've not used a first-gen DA FD, but I have used a 7400 and a 740n --
either 01 or 02; I think it's the latter. Again, it shifts very well over a
44/28 and also did so ove a 38/24.

Now, I may simply be less demanding about FD performance; and I don't shift
the front a great deal (my setups since the 2X9 on the Fargo are 1X +
granny) but when I do shift the front, I don't have any more problems than
I had with more typical road doubles or old-time mtb tripls.

I do have a chain catcher mounted to the chainstay just aft of the bb to
prevent chain suck, but I first installed that on the Fargo with the
46/36/24 triple when I was having chainsuck problems; I've not had that
problem with the 2Xs.

To sum up and answer your question directly re the 1st-gen DA FD: I guess
it will work fine. But if you ask me in court, I'll deny everything.

Good luck! And keep us informed.

and I swapped that out for a 38/24 X something-like 13-26 9 speed (29 1/2"

The derailleurs were both LX of the period. When I converted the chainrings I 
simply swapped the 46 outer for a (BBG) bashguard, swapped the 36 for a 38, and 
adjusted the FD throw limit screw. I did not change the position of the FD on 
the seat tube. After all, the FD shifted the 36/24 properly in that position, 
and it's not surprising that it shifted the 38/24 properly in the same position.

Later I swapped the LX FD for an ancient Dura Ace FD which I did mount a bit 
lower, but for the bottom of the cage to clear the chainstay as well as for the 
lower edge of the cage to clear the (IIRC, 48 t-size) bash guard, the FD had to 
be placed much where it would have been placed for a 46/36/24. The DA FD worked 
just as well as the LX. Again, 38/24 X 15-24 (or close) drivetrain.

Nowadays, I have a 44/28 wide-range "subcompact" setup and the same DA FD 
positioned high enough above the 44 to clear the 48-t-equivalent bashguard; 
here too front shifts are just fine.

FWIW.

Matthews "road bike for dirt" with 42/28 (before I installed the 44) and Dura

of the outer FD cage plate and the top of the teeth of the 42 t ring:

[RBW] Front derailleur options for 38/24 front, 11-36 rear?

[Robert Calton]

Good afternoon group! :) Hoping to tap into the collective wisdom here to 
pick a front derailleur for my Homer build, it's the last piece! 

I'll be using the Silver 38/24 crankset, 11-36 cassette with the Shimano 
Deore XT M761 rear derailleur. I saw that the matching XT front says it's 
for a triple chainring, so I need to find something that's for a double. 

What would folks recommend?
