|Yesterday on my daily ride my left Dura Ace double shifter stuck when I pushed the brake lever to upshift from the small ring to the large ring. It shifted OK but would not return to the straight ahead position. I gave it a very gentle push and it popped back like normal. This happened every time I shifted. It only has about 1500 miles on it, but I shift alot to maintain a very tight cadence range. It's never been in the rain or dust, although it has been very low humidity here in southern california the past few weeks. I seem to remember a thread awhile back about pulling off the top cover and spraying WD-40 down inside to solve sticky shifters. Any other ideas?|

|You can try the WD-40 thing, spray it in the levers while the bike is upside down and let it dry out for a couple of hours (or over-night) then put a couple of drops of Triflow in.....you might try lubing your cable also... at 1500 miles they should just be getting broken in...is this on a new bike? Might be a warranty issue....also check your front der adjustment, cable might have stretched and you need to take in some slack (I'd try this first)...|

|Turn your bike upside down & clean the BB Cable guide & then lub the cables here. I had the same thing you are describing happen & found that Sugar from gatorade Had gunked up the cable guide.

|I had a similar problem. Turned the bike upside down, drowned the shifter in WD40. Have put 1500 miles on the bike since then and it shifts fine. Glad I didn't take others advice who told me to get a new shifter.

|Make sure that the shifter cable is not catching on anything around the derailleur|
|could be cable too tight, also nm||trekkie1|
