STI RIGHT SHIFTER PROBLEM ????

Hose it out with some spray Triflo. If that does nothing, replace it. I know it's a bummer, but
that's life with STI. Garry

When I try to shift on my right shifter from a low gear to a higher gear, big sprocket to a
smaller sprocket(pressing the smaller lever), the brake lever travels over as well and won't allow
the shift to take place. The only way I can shift is to hold the brake lever to the right while I
push the small lever to the left and it will shift. Any solutions ???????

Thank you so much,

Very common failure mode of the right STI. Can try to flush with WD-40, this may help but sounds
like a warranty to me.

DA or ultegra flitedeck? Three year waaranty on DA, two on ultegra.

This problem is very similar to some discussed in another recent thread... I have had direct
experience with no fewer than 5 such failures in the RH lever of STI systems. It is very common, and
9 out of ten times the answer is to replace the lever.

If you simply must have integrated shifting, my honest suggestion would be to move over to Campy if
you can afford it. The quality is superior and, particularly with regard to the Ergo lever, the
thoughtfulness of the design is simply way out in front of Shimano. Note that every time you brake
with your Shimano levers, the shifting mechanism internals are exposed to the elements. This is not
the case with Campy's design. Also, the Campy lever doesn't place the up- and down-shift actuators
in such close physical proximity to one-another.

The nice thing about Campy, too, is that they seem to pay more attention to quality in their 'lower'
end lines. Veloce, which is their least expensive group for a 'serious' cyclist, is on par with
Shimano's Ultegra, and costs less than Shimano 105. I have a friend who uses Veloce, and honestly I
don't see much difference between that and my wife's Chorus set-up.

The best solution, in my humble opinion, is to dump integrated shifting all together and just go
with bar-end or good ol' down-tube shifting.

Best of luck,

Michael Doleman

I've never tried WD-40, but one bike mechanic suggested that to me when I had a stuck right shifter.
Another mechanic freaked out when I mentioned that suggestion, and pointed out that WD-40 contained
high MW paraffinic hydrocarbons which will gum up a shifter. Go figure. I ended up taking it into a
bike shop to get it cleaned up but not sure what they used.

Don't worry about gumming up the shifter, as the lube-flush is but a band-aid to get a few more
miles out of the lever. Once they start sticking, it's Shimano's way of telling you it's time to
warranty or buy new. Think of it as a wear indicator and you'll feel better about it ;-\ --Jim

I had a similar problem about four years ago. Flushed it with WD-40 and haven't had any problems
since (20,000 miles later).

Wow, most don't make it that far. I've used Tri-Flow, WD-40, LPD-9, etc., and most barely last the
season. Obviously, your results may vary. --Jim

with the same exposure, i.e., spray, quick dip or prolonged immersion. WD-40 contains no silicon,
teflon or chloroflourocarbons.

RUBBER: No visible effects on surfaces of various types of rubber sprayed with WD-40. Certain types
of rubber will swell upon prolonged immersion in WD-40.

Effusion Test.

FABRICS: The following fabrics were exposed to WD-40 with no effect, except slight staining which
was readily removed with naptha or dry cleaning solvent: Nylon, Orlon, Wool, Dacron, Cotton.

PAINTED SURFACES: Many types of paint on various surfaces have been exposed to WD-40 with no effect.
Wax polishes and certain wax coatings may be softened by WD-40.

PLASTICS: The following plastics were immersed in WD-40 for 168 hours with no visible effects:
Polyethylene,Formica,Epoxy,Delrin,Ploypropylene,Acrylic,Vinyl,Teflon,Polyest er and Nylon.

Clear polycarbonate and polystyrene may stress craze or crack in contact with WD-40.
