A good question. Jay?

the grip may malfunction only when cable connected to terminal pull...

That is a good question. I'll check tonight.

Dear f***wits, here is my question: you can buy a DT clamp that is a braze-on substitute and install a braze-on FD or you can buy a FD with a clamp built-in. Is one better than the other?

Question No. 2 (for those people who actually know anything), after installing the new 6700 FD (left) Ultegra lever (this is the old 10 speed group), it feels really stiff -- as did the prior lever. I'm wondering if this is because it is paired with an old FD from an earlier group. It also doesn't seem all that happy with a compact, but I don't think there is any such thing as a compact FD. My adjustment is good.

Please submit your papers, double spaced. Grammar will be graded.

If you are serious :-)

The height of the front derailer depends on the diameter of the large
chain ring. The braze-on derailer mount is fixed in place and has a
limited range of height adjustment. Thus if one were to change from a
52 T chain ring to a 44 T chain ring there may not (probably won't be)
sufficient range of adjustment. The clamp on is probably the most
logical choice.

It might be noted that Shimano made some front derailers that were a
brazed on model with a clamp ring that could be used in place of the
braze-on fitting.

I do use braze-ons on bikes that I've built or made major repairs to
but only after considerable forethought. Andrew says there is a slight
danger of the braze-on effecting the strength of the seat tube... but
they look so cool :-)

Re question #2. If you have exposed cables try pulling on the derailer
cable about halfway down the down tube on a number of bike. That
should give you a sense of how much tension is "normal".

BASIC.....check parts as separate untis....

apart from the Chevy method...replace each individual part and bill...

.......super method if yawl bought degradeable parts for the Shelf


ah XXXX the discomflabuator is belly up again......replace....works AAA

a collaree sneaks up here here the discomfla is inconveineinced by the flumarbax.

Flumarbax aare infamous for breaking discomflabulators

ssomewhere a wag worked out a humor for the subject...analysis can be finite in order of congruence.

part A breaking part B while A remains obscure produced great historic disasters tho I'm not coming up specifics beyond the square knot.....

eccentric and unseen joints moving freely when examined individually but jamming when pressured are primary malfunctins

Can I shut my eyes and scream "NO MORE NO MORE"?

You are talking about a front derailleur and not a rear. The bolt-on braze-on was only designed for people that had a braze-on derailleur and didn't want to go through the trouble of getting a more appropriate one to fit their bike.

Is there any real difference between a clamp on and a clamp-on braze-on adapter? No. But there are additional bolts that can loosen or fail.
