Got a DAG-2 (derailleur hanger tool) and RD shifting adjustment is now cakewalk

Got a DAG-2 (derailleur hanger tool) and RD shifting adjustment is now a cakewalk. I had spent an entire hour trying to get it right last week, and could only get it 'almost-right'. Which is actually a lot more frustrating that getting it 'outright wrong' since in that case you'd know something else was going on.

The hanger adjustment I needed to do wasn't even that much. For sure it was off, but def not more than 1cm from top to bottom comparison.

Once the hangar was straight, I felt like it was nearly impossible to get a bad shifting RD. I barely even needed any cable tension - I just gently pulled it taut with my hand, and cinched it down. (I'd been pulling it hard with pliers previously to reach the extreme ends, but no more of that is necessary.)

It's a pricey tool, but honestly, compared to the value of my time spent trying to adjust the 'almost-right' RD, it's worth it.

It's indispensable in any service department in my opinion. At the shop, every derailleur equipped bike is checked with the DAG as part of every service.

I think it's worth it as well. It's use looks simple but can be deceiving. When I tried to use it for the first time, I was not able to get the hanger straight as well. After seeing a guy in an LBS do it, he did many very small bends in many positions around the wheel. So the secret is to take your time and do many little adjustments. Just another tool that takes time to get used to, I suppose.
