i just replaced my gear and brake lines on my 12 speed road schwinn. 1st time i have done this in over 20 yrs.

i am having trouble shifting gears now. what did i do wrong? do i still need to adjust my derailleur? i don't have a mount to keep the bike from moving so i did this with the bike upside down. i put the gears to the top[ most stetting so both r closet to the handlebars. i had a lil bit of slack in rear gear line and tried to pull it tight and when i shift to a different gear it pulls the line tight but the gears r not shifting. help?

Are the deraillers (both front and rear) movable by hand? If not try putting some lubrication on their pivot points like a light oil. Double check and make sure the cables are installed without being kinked.

If its the first time for maintenance go through all your bearings , wheels, crank, head and clean and lube. How to videos on this site.

As per shifters and cables clean and lube, make sure they are not binding anywhere and that they are routed the same as before. Putting a tight bend in can cause a lot of friction, loose is best.

Thank you both. I know the derailers are movable by hand and i will check on the rest and let ya know.
