    I have a Schwinn 700c, 7 gears on back and 3 in front, i want to replace the front and rear Derailleur
    , and the crank set. My rear derailer is Shimano Tourney tx35 and front is probably a Schwinn . Tell me if thesw parts will fit,
    shimano Altus FD-M311 Dual Bottom Front Derailleur and Shimano Altus Rear Derailleur - Direct Mount - RDM310 and Shimano Altus 7/8 Speed Mountain Bicycle Crankset - Black - FC-M311. Also since im new with bikes , please tell me what direct mount. Please ( Idk if it helps but the front Derailleur has a mount)

    Don't know if the parts will interchange, but I can answer the "Direct Mount" question. Direct Mount means there is no clamp supplied with the front derailleur because it's intended to mount to a bracket permanently affixed (welded) to the bike frame. I can't tell from the picture if your current derailleur can be separated from the mounting clamp, if so, that might work. If it's a one-piece unit (the clamp and derailleur are not separate components) you'd need to buy an adapter. The rear should work so long as your gearing is within range (typically derailleurs have a maximum rear gear limit and a range limit). The range limit is the largest front and rear gear (total number of teeth) minus the smallest front and rear gear total number of teeth. Or in other words, if you went from needing the most chain to needing the least chain, what would be the difference in chain length. No idea about the cranks, sorry.

    Try going to at least Deore instead, not much of an upgrade from Tourney to Altus.

    Hard to see from the pics but your front mech is high clamp (aka bottom swing), a direct mount will not work.

    This article is good so you can identify what you got, SRAM and Shimano front derailleur types and mounts explained - BikeRadar USA

    Have you had the existing drivetrain adjusted yet, i.e. cable tightening, hi-lo on RD, adjust on FD, chain check/clean/lube? Unclear if you necessarily need new components.

    The front is a bottom swing also known as high clamp that can handle rings up to 48 teeth, can be used on frames pulling the cable from the top or bottom and can be used on different size seat tubes using shims, the rear attaches to the frame with a bolt just like most rear mechs.

    Before spending money take it to a shop and have it adjusted.

    Just throwing this out as a possibility, if you were trying to switch gears while pedaling uphill with the drivetrain under load, it won't change gears smoothly. You need to change prior to the climb and let off on the downforce for a second if shifting while climbing.
    This post is a natural product. Variances in spelling & grammar should be appreciated as part of its character & beauty.

    Throwing money at something rarely works when comes to fixing something. A better description of the problems would help . Have you tried any adjustments ,replaced the cables and housings?

    I have to admit, you're not making it easy for us.

    What is it that you think will happen if you change the parts? If you think it will make that bike more trail worthy ,it won't. That bike wasn't make for riding off road ,it was made to ride paved paths and roads,and a little dirt road. You want a mountain bike ,get one ,cheaper in the long run.

    It's going to be a lot cheaper if you just buy a used mountain bike. Figure $100 and grandpa can tune it up. Boom! more durable, safer, and you now have two bikes!

    If you let me know your height and a general area in florida I bet we can find you something great for the same cost of upgrading your bike.
