>>969390your advice is true in theory but not in practice. Chance is that OP is using bearings in a retainer (unless they have an old French bicycle, an old English cycle, or some garbage belief that they should pack headsets loose ball), so they would not leave a bearing out. The retainer has already left that bearing out for them, so now their bicycle would have two (2) missing bearings.
In theory bearing grade is important, but in practice, especially in a system like a headset, you can really get away with not caring. Just place the retainer with a missing bearing at the top of the headset, which receives a a very small amount of load.
>>969442>>969444pop your shifter into it's lowest gear. Feel the tension on the cable. It should be taut, but it shouldn't be piano wire tight. Tension the cable if it is loose. If that doesn't fix the problem, go back down to your lowest gear and squeeze the brake lever closed so you can see into the guts of your STI. You should see the head of your cable resting in a small purpose made stop (where the red arrow is point in pic). If the head of your cable isn't in there, you are in a bit of a pickle, since you (or someone else) installed the cable incorrectly. You'll have to fish the old cable out and place it in it's lil stop before you shifting will work.
