    Help! I just bought a Trek 820

    I bought a Trek 820 off craigslist. I paid $65 and it's barley been used. It's a few years old. It's the first "real"/not Walmart bike I've ever owned. Also the shifting is different can someone explain to me how the shifting mechanism works? It feels like I can gear up, but not down. It's not a 2014 model. I know it's at least 5 years old and I can't find this information anywhere. Pictures will be attached below:

    There is an identical mechanism on the left side

    ^ That is back side of the mechanism.

    If its like the shifters I had on a previous bike, one button is for up, the other down. Never had an issue with it, but they did change the design later.

    I was excited by the prospect. The guy didn't know what he had. I didn't really know either. I needed something for college. Figured I could find someone who knew.

    That's how I assumed It'd work. Maybe it's just be but, both triggers feel like they're gearing up. No matter which one I hit the pedaling just stops doing anything productive.

    Best thing to do would be to take it in to a local bike shop, and have them give it a once-over to see what kind of work/adjustment it might need, if any. They could undoubtedly also help you out with learning how the bike's componentry functions (or should​ function, at least).

    I guess I'll take it over to one tomorrow.

    It probably just needs some tweaking. If its the shifters themselves, they aren't expensive to replace.

    That's Shimano Rapidfire, not Rapidfire+, Rapidfire hasn't been available since the very early 90's, it was defiantly gone by 1993, so that bike is 20+ years old at least.

    My previous hybrid was bought three years ago, and came with Rapidfire, not Rapidfire+. I am not questioning your dates, just that sometimes makers get creative. They don't throw out parts.

    no worries. I've been there too. once bought a bike without even spinning the wheels and found out at home one needed to be replaced. oh well. sounds like a decent bike, so what if it needs work. most used bikes do. whether it's just cables or undoing what someone else messed up. a ride-ready tuneup from a bike shop will be money well spent. have them check the wheels while they are at it ...

    Really? WOW. You bought a NEW bike with push-push, under the bar shifters?

    What make/model was that?

    Most manufacturers don't hold onto parts from 20+ years ago.

    Sometimes they just need a good flushing with copious amounts of WD-40 to get shifting again. Sometimes they're just plain broken and it would take a watchmaker to fix them.

    If replacement is needed you should be able to get into some 7-speed trigger shifters and some decent brake levers (make sure you get some that can be set up for cantis) for around $50. Probably $25-50 for installation.

    Shimano 200GS shifters. They came on my very first real bike. It was a Diamondback Sorento bought back in 1990. If I remember right this was Shimano first or second year going to push button shifting. Worked quite well. Like said above they only were around for a couple years then everything went Rapidfire+.

    Until #rumrunn6 comes back, thinking probably Mircoshift, as they are a similar (Visually) design to the old Rapidfire shifters

    Ah think you may be correct, and I could be mistaken, it was Microshift not rapidfire, but the buttons look like the OP's picture.

    Yes it happens, I make mistakes. I'm an old guy with fewer active memory brain cells.

    But they work the same way as the rapidfires, two buttons/levers one for up, one for down, one over the other. I know they changed it, but I never had an issue with it. My son uses that bike now and he loves it compared the gripshifter on his older MB.

    Man, I miss those shifters. I had to have mine replaced and it took a while to get used to the new ones.

    If it's a 7-speed it's most likely a 90's era bike. Do you have a photo of the entire bike?
    Currently riding a 2013 Handsome Devil custom build and an early 90's Specialized Rockhopper Single-Speed.
