Bike discount do one at £29 one posted, or the CRC one at £40...

Any other options though?

Cheers guys!👍

EDIT: This is just as relevant on a replaceable mech hanger on a mountain bike, right??  😉

The CRC one looks like it has more clearance where it threads into the hanger (like the newer park one).

How about buying a new hanger from Superstar? £7.99 or so 😉

Haven't used the tool you mention but I bought a cheap ebay one a while back

The tool itself has a fair bit of play in it, like 5mm by the time you're measuring position of tool handle relative to rim!

Still it's perfectly usable, you just try and bend the hanger to where you estimate the middle of the tool's play is. Does the job for my steel inbred frame (with integrated hanger).

An olde worlde cup-n-cone rear axle threads into the mech hole on the dropout. THen stick a straight edge- I use a bit of old threaded bar, other straight things are available- through the droputs, to give you a comparison, and straighten by hand/eye. Easy

Google DIY hanger straightener. Loads of examples much cheaper than buying one. Making one for myself at the moment.

As long as you take up the play the same way by pushing in or pulling out for both measurements its fine.

I have the cheap lifeline one, loads of play, in use it doesnt matter so it does the job and if I didnt have it I would buy again for sure.

Well, went for the x tools one in the end.

LBS want £20!

Are you kidding? So use it twice and it's paid for...

I have two (check me out!), a cheap x-tools one and a parktool one. They are night and day to use by both work. The cheap one has more play so you have to take account of that but it works. The parktool is more foolproof, it has no play and a locking thing so it is really easy.

super useful tool, I use it a few times a week.

The Lifeline one has a grub screw the same as the Park one to take the slop out IIRC. Not sure about X-Tools.

Good to hear that the cheap option works....with a bit of "initiative". Lol

I usually can't run to park tool prices unfortunately, though it is nice stuff for sure!👍

I've used an old bolt-on front wheel from another bike; screw it into the hanger & move the wheel around until the two wheels are about parallel vertically & horizontally (or something like that, maybe I rotated it to check the same point crossed the other wheel at the same distance, was years ago, but it worked well).

As someone said an old front axle and a bit of steel with a 10mm hole.

If your passing by gatwick airport I will do it for nothing. I had a bit of square tube left over from
something and made a hanger straightener;-) I used to use a pair of Stilsons and a straight edge!

The tools are really useful for steel frames as bending steel does not affect it's structural performance but I would not recommend trying straighten out a cast hanger as the grain structure is coarse and it will snap quite easily and for the cost of a replacement it's not worth risking.
