I am a new trek 1000 owner and need detailed operating
instruction for the double shimano sora shifters and
any insights would be appreciated also.

I would recommend that you take your bike to the Shop and ask them to give you instructions...I'm sendin these sites for future DIY info....

Bonne chance!

Most newer riders (and I recall myself in this boat) make two typical errors with regard to shifting and riding in general.

1. Not shifting enough. That Trek 1000 has 24 gears. Use 'em. The shifters are located right where your hands are most of the time, so why not adjust constantly for variations in road grade, wind, desired speed. You'll be a whiz in no time just by forcing yourself to run through the gears. Depending on where you live, it is possible that you won't spend much time in your front chain ring (sometimes called a "granny ring") because it is mostly for big climbs.

2. Pushing too big a gear. You'll want to "spin" your feet fairly quickly. If you are good at counting it or have a cyclocomputer that measures cadence, start out trying to keep it around 80 or higher. In any event, no need to feel like you are "mashing" or pushing a bigger gear. It will fatigue the quads unnecessarily, and for some even irritates the knees. There's really almost no reason for cycling to bother your knees if your bike setup and technique are okay.

I remember being a little daunted by shifters on my first "real" road bike (ie., not the Schwinn Varsity of my youth), but within 2-3 rides where I really looked down and shifted a lot, it felt better.

The basic principles you'll learn are that the SMALLER the ring in front, the lower the gear. The front rings are the "big" jumps (like jumping chapters not pages, I guess, for a book analogy). In the rear, the BIGGER the ring the lower the gear, but the increments are smaller (like pages not chapters).

If you don't want to think of it as "big" or "small" you'll just see that shifting the chain towards the frame of the bike is always downshifting (easier pedaling) whether in front or rear. Look down a lot. Understand where you are in your gears and what actions have created the feeling you are getting in your legs. Soon you'll never look down again, but at first I think it does help self-educate.

Your right hand shifts the rear, and if you ever forget I suppose the easiest mnemonic is that both RIGHT and REAR begin with "R" (duh). Obviously, the braking is the same

Hope that wasn't more basic than you sought. Good luck and please visit here often. There is a wealth of info and good folks.

To shift in one direction you push the little lever with your thumb. To shift in the other direction, you push the bottom of the brake lever toward the middle of the handlebar with your little finger.
You must have strong pinkiesjtolleson

I couldn't shift an STI lever with pinky only... or at least I don't. I'm betting (can't totally picture it but will check later) that I use at least two figures when shifting via the brake lever. I use only my middle finger to shift the small lever (don't have Sora)
