Fix Shimano 200GS and many other trigger shifters without even taking them apart. You don't even needs any tools. These shifters are on a 1991 Trek 820 mountain bike. The right shifter wouldn't catch to shift to the larger cogs. It was also very stiff when it would catch a little bit. The left shifter would shift to the larger cog, but wouldn't catch to stay there. Basically it's the same problem that all these shifters have. The pawls get stuck with old grease or oil. they just need to be cleaned up and lubed. But these shifters were easy to fix as the mechanism is accessed without having to remove them or take them apart. **If the video was useful or interesting please give it a "thumbs up" and consider subscribing. -Website: http://www.RJTheBikeGuy.com -Facebook: https://www.facebook.com/RJTheBikeGuy -Subscribe Here: http://www.youtube.com/subscription_center?add_user=shyflirt1 -YouTube Channel: https://www.youtube.com/RJTheBikeGuy

thank you very much for this simple video it's going to help me a lot with my problem, I just have one question after I clean everything with WD-40 I have a high-end silicone-based 3 in 1 oil .Can I use that to lubricate the pawls?

This video has a very cool stroboscopic effect at 1:00-1:03: the tire seems to be moving in the opposite direction of the spokes.

Thanks! My Trek 7200 had this problem on my rear gears. WD 40 worked like a champ! I will add a regular spray lube next.

THANK YOU! I just got one of these off Craigslist to use as my heavy cargo bike and the shifters are really caked. I got the rest of the bike working and I had been dreading taking those things apart. I'm out to try your method right now.

Thanks!

P.S. Do NOT subsitute WD 40 with Carbarator cleaner, Melts the plastic and gets on your fingers! LMAO ....yeah a lil Birdie told me. ;)

Same problem on my wife's Trek Antelope - this worked!

Thanks for posting this, So simple and saved me a lot of money. I thought I would finally have to replace something on my Marin after 16 years of faithful service but NO!!! ;-)

What cable size is the 200gs?

Triflow is great stuff ....smells really good too --LOL

Thanks for the great information! I took my bike to a repair shop, they said the shifter was non-repairable and they wanted $50.00 to replace it...I said no...found this video and they now work like new! Thanks for saving me the money....

Awesome!

Thanks for this - mine had been stuck for years and a shop had told me they weren't repairable and would have broken inside (spring or similar). Half an hour working the shifters while soaking with WD40 and they're now working good as new! The large lever to work the rear derailleur was the worst and took forever, but once things started moving properly they sorted themselves out. Thanks again, probably wouldn't have tried something so simple before opening them up and no doubt breaking them!

I also found Tri-Flow at a Fred Meyer store back in the Seattle area (sort of like a Walmart type store). Auto parts stores might carry it too.

Cool!

Thank you for posting this! Mine was quite badly stuck, and it took a little more spraying and working than the video showed (I almost gave up), but eventually freed up, and now works like new.

It's called Tri-Flow. You can find it at bike shops. The books I have read suggest a heavy oil or a light spray grease. Many guys in the bike forums recommended Tri-Flow as did the guy at the bike shop. So that is why I am using it. I has worked so far. I think this is one of those things where many different things will work and it is a matter of personal preference.

What kind of lubricant did you use? Not familiar with the brand you mentioned...Is it silicone based or what?
