Have you checked that the cable is running thru the casing and under the bottom bracket nice
and smoothly?

Correct, Almost impossible to take apart and reconstruct but no small parts available anyway
from shimano.

May try flushing with 'STI repair kit', WD-40, but Quality Bike Parts, a distributor, sells single
STI levers.

How long you have the bicycle, By all means flush the units with either of the fluids mention
previous replies, WD40 or Powerlube. Shimano warranty this unit for two years, however, my unit was
replaced and it was more than four years old. Contact Shimano via their webpage or at this phone
number 949 951 5003 X 2900. I have taken the right level apart and drilled a hole so as to get more
tension from the old spring. http://www.billcotton.com/sti_shifter_repair.htm since the parts or the
aren't available from Shimano.

The right side tends to fail more often, and most folks buy a pair since the price isn't much
different. So there should be lots of left side levers around. Try eBay.

These levers are really poor. They last for 6 months then rattle themselves to death.

Be careful of lubing, these units are held together with screws that are coated in a thread lock.
After I lubed my right unit, the screw holding the two levers together came loose every 5 miles and
it wouldn't shift. Eventually it dropped out all together and now it rattles like crazy.

I heard that the Ultegra levers suffer the same problem. This is one reason why Shimano have changed
their 105 design for 2003.
