Christopher Brunsdon Posted August 20, 2009 Posted August 20, 2009 So a combination of a wipe out at Gravity and the Broomstix Cleaning Executive banging a solid door against my bike has resulted in a bent derailleur hanger. It was friggn awesome on my commute home tonight. So as usual I fire up google and discover to my dismay that its going to cost me R1K for a hanger alignment tool - Park Tool of course. No one seems to really stock the Cyclus which works out about R300. So anyone own a tool? Whats your opinions. From what I could see on the interwebs is that everyone swears by them. I don't mind paying for descent tools but R1K is a bit ouch. Considering of making my own with 10mm bolt and square tubing.
Peach. Posted August 20, 2009 Posted August 20, 2009 take your derailleur off, leave your wheel in place, take the biggest shifting spanner you can find and bend it straight.It works like a dream Peach2009-08-20 13:31:39
Racer X Posted August 20, 2009 Posted August 20, 2009 Either buy the 750 buck park tool off CRC, do what peach said or find two really decent bits of sheet metal. Insert the bent hanger between them and then go and find a really big hammer... Presto, like new.

[/quote'] JB is the man Hanger was not seriously bent and I did bend it straight (kind of) with my leatherman. Its too dark and cold outside to prick around with it now. Will see in the morning.
quickdraw Posted August 20, 2009 Posted August 20, 2009 I have one that you are welcome to use, but I am in Plumstead - so probably out of your way. If you are in the area, just give me a shout. 0828287437
Christopher Brunsdon Posted August 20, 2009 Author Posted August 20, 2009 Thanks for the offer. Not planning to go out that way soon but might take you up on the offer one day
Matchstix Posted August 20, 2009 Posted August 20, 2009 the tool will be worth it in the long run, If you want to make a tool just remember that the thread that goes into the hanger is not a standard M10 thread. cant remeber the exact dimensions but you can google it.
Dirtbreath Posted August 21, 2009 Posted August 21, 2009 New hangers are not always 100% straight. Might be a bit pedantic but lining up a new hanger is a good idea for perfect shifting. Still dont think I would buy the tool for 1k though.
dirtrider Posted August 21, 2009 Posted August 21, 2009 If you bend your hanger that often that you need an alignment tool I think it is time took look at the way you treat ur bike . Anyway if you have bend your hanger so badly that it affects your shifting you are just going to break it trying to bend it back in shape . Just buy a new hanger .
Matchstix Posted August 21, 2009 Posted August 21, 2009 not really a hanger can be bent slightly and affect your shifting dramtically. especially on MTB on you higher gears. The second thing is that some derailluer hangers are softer than others. I remember that the old cannondale hangers were very rigid and would brake if you try to bend them back. Some of the softer ones bends easily but can be bent back just as easily without braking them. The biggest problems that affects shifting in my experience, other than dirty cables is a bent hanger

droo Posted August 21, 2009 Posted August 21, 2009 I'm of the opinion that if it's a once in a while job, the LBS can do it. Same reason I don't own a headset press or a BB shell facing tool, it's just not worth it for the amount of use it'll get.

I have a GIANT and their hangers are soft and easily corrected. Not so sure what a hanger costs but it seems that R200 is the online price (CRC). So 1 tool is = 5 hangers.
