Hey everyone, I'm brand new to the forum and still very new to biking. I've recently gotten really into riding, but havent had a road bike to use. After searching for awhile, my girlfriends dad gave me an old schwinn 10 speed which im fixing up. I am keeping alot of original components, but replacing all of the "drivetrain?"... crank, freewheel, derailleurs. The shifters and brakes are salvageable for now. I was looking for a bit of help on compatibility as I can only find so much out on the internet. 1.Would this crank be able to replace the original threaded crank? Bikeman: FSA Omega MegaExo Compact Crankset 170mm 34-50t Black w/ BB 2.if so, can i use a 7 speed shifter on my 5 speed such as... Shimano Tourney/TY TX71 6/7-speed Direct mount rear deraille.. 3. what compatible front dérailleur would you recommend to compliment the two. I know this is a lot to ask, but i need the help. Thanks!
