Mech hanger £15 or Alignment tool £30

[DrSquirrel]

I need a new mech and hanger - I could get a hanger for £15 or the alignment tool for £30.

Which would you say is best?

If the mech hanger is alloy, you'll need a new one. Aluminium is remarkably intolerant to being bent - even if you manage to bend it back into alignment without it breaking it's been seriously weakened and will fail.

With steel you could probably get away bending it back. But most mech hangers are aluminium alloy.

+1The hangers are designed to be the weakest point to safe the mech from being damaged.

That's a bit too categorical. They're soft alumninium and you'd probably get away with bending a hanger once or twice but not much more. I have.

OP. If you buy the tool you can check for and resolve many instances of the problem, if you buy the hanger you just get to replace one that you know is bent. You pay your money and take your choice.

With over 200 different hangers to choose from, great fun will be had by all!

Luckily I know which one is needed anyway...

I realise that - and im not looking for the cheapest option - just that if the alignment tool will help me out in more cases vs needing to replace a hanger anyway.

I guess another advantage with the tool is I can use it as and when, rather than waiting for a new part.

mech hanger....you could try bending the current hanger back into place using your hand, but you are unlikely to need more than 2 more hangers

I have just had my hanger straightened, it was only out 2mm but it really screwed my gears up big time.

I have experience of hanger failure
Snapped in half, followed by the mech being ripped out of the frame, which then snapped the chain, which then cut into the frame.
It went as I was riding up a hill... at the time I was more grateful that I was sat in the saddle as (based on the way it went bang) had I been standing, I think I would have been crying over more than a broken bike!

Simple really.

I also suspect the tool is for brazed on hangers that actually can be trimmed with bending so that they run in line with the frame, with a bolt on aluminium one it's straight or it's in the bin.

I have though on occasion straightened bolt on ones one by leaving it clamped in a girt big vice, it wont take repeat performances of this of course.
