Ultegra 6700 3 gear change problem

extrusion

Hi

Find this difficult to describe so bear with me.

I'm having a problem with new shifters I added to my bike, so I now have full ultegra 6700.

Everything works fine apart from when moving the rear derailleur from smaller cogs to bigger BUT doing it with 3 clicks in one go (full sweep). The chain jumps up the cogs fine, then I let go of lever and it drops back down one cog.

This only happens on the last 5 or 6 biggest cogs.

Prior to this I had Tiagra levers which worked fine.

You would think increase cable tension perhaps, but I did this which worked, but meant I could no longer shift to the smaller cogs.

Very very odd ...

Any ideas anyone??

Wild guess. The lubricant put inside the shifter internal mechanism when they were manufactured has conjealed over time siting in storage somewhere. So may not function 100%

Try re-lubing the mechanism with spray grease or oil.

The proper way to do it is flushing out the old lube with a degreaser. Then clean it off. Then re-lube.

Seems very smooth to shift otherwise so I'll relube as a last resort. Oh wait, last resort is a new frame!

After some garage investigation the shifter doesn't click on the third click if moving from cog 4 to 1 or 5 to 2. I guess this means it's not engaging and therefore the shifter is either a load of cack and needs to go back or as you say some lubing is required!

You could just one click one gear....?!?

Multiple shifting... spend a bit more money on Campag.

Cos I'm used to doing three when I need to ...
Just read the F manual, it only specifies 1 or 2 shifts. doh! Why can you do three in some gears then !?!? Oh well. Shall have to recalibrate my fingers.

Or spend a bit more money and completely change almost every mechanical component on my bike. Yes ...
