    So I was at Sears looking at torque wrenches and they had 2 models, one that went from 25-250 in/lbs and one that went from 10-75 ft/lbs. When I was there, I thought they were both in ft/lbs, so I got the 10-75 ft/lbs model. Now I realize that the other one is actually in in/lbs so I need that one (I need a lower range), but it only goes up to about 20 ft/lbs of torque.
    This is my first torque wrench, so:

    How often do you use more than 20 ft/lbs of torque when working on your bike? Do you ever, or is 20 more than enough? Will I need both the larger AND the smaller model, or just the smaller one for regular bike work?

    Thanks!

    keep that one for your vehicles if you will ever work on them, otherwise return it. the most typical range you will need is odwn to 10 inch pounds. I prefer the clicker type wrecnh rather than bar and needle type

    Ok, I don't have a car yet, so I'll pick up the other one.

    Thanks

    on cars, 20lbs/ft and more is extremely common.
    btw, torque wrench accuracy has a sweetspot (usually around the middle) and then drops a little from there to both ends, so its good practice to have more than one wrench with overlapping ratings.

    stay away from bar and needle wrenches. clickers are way better.

    Yeah, no car for me but it sounds like even though both would be nice, I'd only need the smaller one, is that right?

    What do you mean clickers and needles?
    Mine has the main shaft and the grip rotates around that and makes little clicking sounds every half pound/foot. Is that what you mean by clicker?

    Here. I'm just not sure where "here" is.
    The clicker-type are technically called break-away because they physically have a break in the movement when the set torque is reached. I know this because almost 30 years ago, I used to calibrate torque wrenches.

    While a calibrated "clicker" torque wrench is more accurate, when used correctly, an indicating type is just as accurate for the home mechanic. I use an indicating type wrench myself.

    I actually was in the exact same boat. For xmas I got the inch pounds version and exchanged it for the foot pounds version. usually the only thing I use TWs for is bottom brackets and cranks. which are generally 30-40 ft lbs.
