Sticky STI shifters(4 posts)

My STI shifters (105) are a bit sticky. They aren't very crisp. I would like to recondition / repair them or find someone who will for a reasonable fee. Advice on how / who? I'm selling the bike and don't want to spend much; especially not $150 to replace them.

Sticky shifters are common in cyclo-cross with all the mud or dusty road rides, I usually flush the shifters with soapy water and/or compressed air.

If the cables/housing is a year old you should also change those. Rusted or grity cables hamper shifting and braking, not to mention the possibility of a broken cable.

They even are sluggish off of the bike w/o cables attached. It's the rachet mechanism inside the shifter which is crapped out. Any hope?

You can try flushing the shifters with a generous spray of WD40 or something similar. Then chase it with lubicant spray such as GT85.

Good luck.
