Part of the DERAILLEUR snapped [56k warning]

Hi

After squeezing my bike (Saracen vice 7002 aluminum) into the back of my car the gears have not been functioning correctly. I managed to fix the front gears by tightening the cable as seen in some videos (in the links from stickys)

I then got to the back gear which is meant to have 7 except 1st year is actually gear 3 and 7th is gear 4 So I spent a long time trying to tighten it like the front gear but with no luck. I then noticed that a part had snapped. I have taken pictures and just wondered if anyone would point me in the right direction of what I need to buy. Or weather a LBS would be better? and how much such a job should cost me. From my web searchs the only parts are as about as expensive as the bike

i have taken some pics, I have tried to use a hat (from my phones photo thing) to point towards the fault. The plastic seems to have just snapped.













THANK YOU for any help
Ben

Where have you been shopping? An upgraded rear derailleur for that bike is less than $20:

get to know your lbs mech and I guess its owner or salesman--- when you upgrade maybe you'll get a lesson and a deal...... being personable with those in control helps... this is not an expensive part.... but if you do it yourself and you do it wrong than you might pay more in many ways....

kool thanks, I found the same sort of thing on ebay for 15 which seems ok, the only thing I am not sure about is.

1)Will it fit all 7 gear bikes?
2)It does not look like the broken part is included, is that bit needed or what?

Thanks for your super fast reply and help

Ye I think I will ring a few tomorrow, see what they say on the price side. Because I read some want 125 ($250) just for the labour (incs a basic service) and then I would have to pay there part prices too.

I have a mate at school that built a BMX bike, maybe if I ask him nicely he will help lol. I can change break cables as stuff like that, this looks overly more complicated though

Thanks again for your help

Almost all Shimano derailleurs are cross-compatible (the exceptions are rare and expensive).
The broken part is the cable adjuster. It's included on the new derailleur, except it's in a slightly different spot. You may need a little more cable housing and a new derailleur cable to make it work. All the more reason to make friends with your neighborhood bicycle mechanic.

I just found new ones for $10 on average. That and a book or Sheldon Brown's website is all you'd need. Easy enough to learn to install and maintain a derailleur.

It doesn't look like it's actually broken, just the plastic finger knob which isn't essential. Either way, your LBS probably has one kicking around that they'll give you for nothing.

PS- does anyone actually still use 56K?

I put my specs on and the pics were still blurry. Must be a $2 camera.

Good news! The bike has been fixed not sure how.

he said it just screwed back on? and the gears needed re aligning. I think however he could of just glued it on and then sorted out the gears but works perfectly now and it is hardly a part that goes through a lot of strain so glue should be fine anyway?

In the end cost 15 ($30) plus a new break cable.

He also suggested my wheel needs re-tuning, I did not really feel it was worth 15 and leaving my bike there, but is it something that is possible to do at home or not?

They where not that blury, but the camera was only a phone. You did click on them right for a bigger version?

Just a photo tip... try using your macro function for those close-ups. Camera should have a button or icon like a flower... Allows you to focus on those close objects(6in-18in or so).

I don't see anything broken. You unscrewed your barrel adjuster too far. Very simple.

Try to take this as constructive, but if you didn't realize that, I think you'll be way over your head trying to work with wheels. Don't do it unless you have someone to teach you.

Perhaps he suggested "re-truing" (adjusting the spokes so the wheel is round and has no left/right wobble)? As others have suggested, working with wheels is among the trickier aspects of bike work. If you spin the wheel and don't notice any big wobbles, you're probably fine for while.
