I was riding my bike and the chain jammed between the smallest sprocket in the back and the frame, and I popped it back in. Now, when i go to shift from the middle sprocket in the front (2nd) to the biggest one (3rd), the chain makes a grinding noise, and I have to press the shifter hard for it to shift up. The only time that this doesn't happen is when I'm riding faster than about 20 MPH.
The Bike's a Trek 4100

Hey Cms,
-Your rear derailer "High" stop needs to be readjusted. When you go to your smallest or your highest gear the rear derailer is pulling the chain way too far outward past the small sproket and the chain is getting jammed between your frames dropout and small sprocket.
-When you are trying to shift from 2nd to 3rd your bike makes a clicking or chattering noise because the rear shifter needs to be readjusted. Your rear derailer is not pulling the chain over to the third gear, it is stopping between 2nd and 3rd gear. You mentioned that you had the bike tuned-up on Saturday. I suggest taking it back, because they did not do a very good job adjusting your rear derailer. They will also have to readjust the front derailer after the rear is readjusted.
You might also need new shifter cables if the shifting is really hard or sticky. Hope this helps. = )

This is what it sounds like. Your front derailleur needs fine tuned, probably nothing more than a quarter turn or so of the barrel adjuster. The chain sticking is called chain suck and can be the result of a worn or dirty chain. Replace the chain or at least clean it. Check the chain to be sure it's not bent that can happen when they get stuck and you pull them out like that.

sure it relatively is undesirable (undesirable habit). yet that does no longer propose there something incorrect with the motor vehicle yet. yet once you have been to try this commonly you will smash your syncro-mesh (the area of the handbook transmission that stops the gears from clashing and grinding). as long as you notice no different concern (different than the gears stepping into with partial clutching), you haven't any longer have been given a concern yet. merely determine you grab each and each of ways any further. good success. P.S. you're saying "something" is incorrect. What makes you sense there is something incorrect? be careful approximately bringing in vehicle to a mechanic. they're going to locate something incorrect - relatively on an previous vehicle.

I would suggest taking your bike to your local bike shop and having them take a look at it and to check if your bike needs a tune up.
Other than that, always make sure that your bike is being taken care of and you are keeping up on the maintenance should keep further issues to a minimum:
Keeping your bike parts properly lubricated is crucial for good performance. Lubrication protects moving parts from excessive wear caused by friction and keeps rust and corrosion from attacking exposed metal components.

Your chain may have become damaged. Had this happen to me, although it was wheel and casset that it became jammed between. If your chain is bent, or damaged, you might damage your cogs.
Check your chain and replace any bent or damaged links. You might also have moved your derailier out of true, so you might have to re-index. But I would say it is your chain. If push comes to shove, you could always get a new chain.
Luck
