JRA....

up the hill towards Lynne Briene, when....

There was a crunch, and everything stopped moving...

[img] [/img]

Kamikaze Mech had caught a spoke and hauled itself into the wheel, destroying itself and bending the mech hanger so much that it caught on the gears...

Much faffing and debating resulted in a fine singlespeed bodge by the combined efforts of the EMBC crew and got me up the hill back home, but I am left with a very bent mech hanger-

Anyone had any luck bending them back? As it's steel, it's not a separate one, so I can't just buy a new one ๐Ÿ˜ฅ

Is that an inbred? I did something similar to mine coming off Jacob's ladder (and indeed bodged it singlespeed to get home) - that nice man Jon at my LBS [url= http://www.bicyclesmithy.co.uk/ ]Bicycle Smithy[/url] bent it back into place for the price of a couple of bottles of beer

use an adjustable spanner to get it back. If you want to be absolutley sure its aligned correctly take it into your LBS (Clive Powell?) who can use tool on it.

I'd sned someone like Argos Cycles a pic with the wheel out and mech off and see what they say.

You might get away with a big flat spanner and a bit of effort from your lbs to straighten it but it might be best to get a 'proper' freame shop to do it as they can put some heat on there too if they think they need to.

Mech should be Ok with a new inner cage. ๐Ÿ˜‰

I'd agree with decent bike shop checking the frame hanger.

[s]Nope - I'd dump the hanger and get a new one - Unless you have a tool like above I doub't you'll get it shifting properly - tried it on my Orange Five and I couldn't understand while after a while it wouldn't index properly - replaced the hanger and whey!![/s]

Ooops - integrated hanger - Yup as above take it to LBS (if decent) to get it bent back and aligned with "the tool" ๐Ÿ™‚ ๐Ÿ˜ณ

It a Voodoo Bizango ๐Ÿ˜ฅ

Wasn't aware of hitting anything as I came down Doethie valley, but made some odd chain noises as I came back up the road to the Reservoir , and then that....

Sounds like it's a matter of finding an expert bike wrangler and plying them with beer til they get their tool out. Shouldn't take long... Does anyone know of such a person in Devon? My local bike shop is full of knuckle draggers...

If LBS re-align tool doesn't work, you can always get it welded & retapped - M10x1.mm I think.
Or use the Shimano saint type axle mount for the mech?

Find a decent LBS, be prepared for an hours labour.

Biggest problem I had with my Ti frame when it did the same as you was closing up the axle 'gap' We got the hanger aligned and to 10mm, but needed 9mm...

Ended up sending it away for a new chain/seat stay and drop-out.

if it does snap off, one of those 'emergency, fit any bike' hangers might do the trick..

Dead easy to fix. Just remove 8 of those 9 cogs back there and that useless lump of bent metal. Shorten the chain a bit and you're sorted.

Also remove the bird's nest that has been made in your frame. HTH.

that should easily bend straight with an alignment tool. I bent a rear hanger on a steel frame 90 degrees backwards and 90 degrees outwards (so basically horizontal) and it bent back perfectly. Cost me about 4 quid at the LBS.

I did that to my 456. I tightened an adjustable spanner around the hanger so all of it was in contact. Then I bent it back. That was 3 years ago now and it's going fine.

I did it by eye.

Adjustable spanner works. Shimano-style axle works better though- the thread is the same as a mech and it's far easier to gauge when it's straight. That's a hell of a bend but it'll probably be fine.

be careful with bending with a AJ not to distort the thread hole for the mech. if u get what i mean
