Hey Guys.

Next issue I have with my winter/training bike is my 105 STI leaves have some funky marks on the levers.
The lines seam to be some sort of corrosion and the finish is flaking away.

As you can see there is some damage to the plastic housing but none to the levers.
Bike has been stored in a dry garage for 2-3 years and they went like this.

I was thinking of dismantling them and getting them anodised.
But going to return them to the dealer for a quote to fix first.

Anyone experienced this or any cool ideas on how to reuse them.

Alan

Hi, Just found someone else with the same issue.

http://weightweenies.starbike.com/forum/viewtopic.php?f=3&t=30361&hilit=Corrosion+105

looks to be from a faulty batch.

i've seen this quite a bit of shimano levers... mostly the 9 speed era stuff though that's been around longer - ultegra and 105... maybe it is from sweat penetrating through the anodize and causing corrosion?

I've encountered this on a couple of bikes and buffed back to clean metal using a combination of a rotary brass brush stripper and steel wool. Then Autosol paste for a final polish.

The exposed surface is still prone to corroding (but not the creeping lines as per the pic above) and can be repeatedly cleaned up again without too much effort. Applying automotive or marine wax helps keep them shiny for longer.

Hasn't happened on Campag alloy levers which seem to have a milky anodisation treatment that is pretty tough.

Hey guys,

The only thing the local bike shop could do is give me 10% discount of a new pair of STI levers.
(treated myself to a pair of new 105 STI's)
And I got nowhere with Shimano.

So... I dismantled the levers and sanded them down and polished them.

Then I found a local anodizer through a friend and got them anodized.
(They came out dark due to the levers being cast aluminium)

They will do great for my fiancée's bike, if I ever pick one up, I can convert it to 10 Speed.

Alan

Nice work. What did you do the initial clean up with?

Hi, various gains of sandpaper (1200 to finish) then autosol metal polish.
