adjustment tool bike front derailer
What tools are available to help hold the derailer in place for tensioning the cable?

No such tool needed. FD is bolted to the bike and in bolting you adjust for height relative to the large
chainwheel and angle as well. Once these are set the mounting bolts are tightened. Then you adjust
the limit screw for inward movement of the cage to just clear the chain when the chain is on the small
CW and largest cassette cog. Only at this time do you connect the cable to the FD and begin the
task of tensioning the cable. The least tension scenario is when the FD is on the small CW and this
is when the cable can be tightened by pulling on it with plyers as you tighten the cable clamp bolt.
Maybe I am missing something here......

The most important tools for front der adjustment are your eyes and your brain. All else can be bought for much less. Andy (who knows that having good tools are second to better skills)

Agree and this requires having a good working bike stand so you can see and think and comfortably work on the adjustments.

I have found a 4th hand to be useful for adjusting front derailleurs

Park Tool site is great if you'd rather read. Shimano's own instructions for their 11 speed, I doubt I'll ever be able to commit those to memory.

Although no special tool was needed, my last adventure with an R7000 FD was frustrating to say the least. Cable
routing is a bit bizarre and even with 3 redos the shifter effort is higher than it has ever been on all previous bikes.
