Dura Ace front shifter woes

[Mike Muz]

Morning all ,

Tried out my new build on the way to work this morning .
All worked ok but for the front changer . It's a 7700 Dura Ace downtube shifter that doesn't want to stay where I put it , regardless of how much I try to tighten it by hand , and gradually edges towards the stop , it will end up shifting to the small chainring if I don't keep adjusting it , and that will never do!
It has a loop on it to tighten it up , and I'm tempted to use something on/through it to stop it from moving , but don't want to bend that either .
Should there be a washer or something between the mounting bolt and the plastic cover over the lever ?

Can anyone advise pleeeeese ?

Thanks ,

Mike

Morning Mike,

Have you the Shimano model number?

I remember stripping my DA 7401 gear levers and putting them back together wrongly and they just slid back,
after trial and error fitting a few different ways, they worked.

Hi Richard ,

It's a 7700 shifter .

Cheers Ian , think I'll have a rummage for a thin washer to put between the bolt and plastic cover when I get home . Should be a nice ride , the Sun has come out now

Still not sure if the frame is too big . :facepalm: Will put a quick thread in the readers bikes section soon .
But that's something I will find out during next weeks group ride which will be around 50-60 miles

My loft is ok actually , and I draw up the ladder when I'm up there so my finds are not found :facepalm:

Good plan,

Would work for me except there is not room for the ladder!!! Luckily my wife avoids ladders but i have to be careful she does not look up through the hole.

Last year I was waiting for a large box of bits, I had my friend call round and distract my wife. The van arrived and we got the box into the garage without being noticed. In the garage i unpacked the box and got the stuff into the attic quickly. I then cut the box up and got it into my friend's boot before my wife appeared.

What a tangled web we weave....

p.s. The plan worked so well, I have used it since!

I'm going to have to think up something . Mrs Muz is moving in next weekend . At the moment , I only have to hide stuff on Thursday evening before she comes over on Fridays .
You should see the state of my kitchen mid-week :shock: Thank goodness for easy wipe vinyl flooring
