Newbie question - should I be concerned?

Hey guys,

I just got my first road bike a couple of weeks ago and today was just my fifth ride, so please go easy if I am worried about nothing. Today when I started out, I messed up and was trying to use my left hand to change the rear derailleur and of course was in fact shifting the front one. But, I realized it pretty soon, though at one point it looked like the chain was caught in between the chain rings for a couple of seconds and then it was fine. Then about 6 miles into the ride, I couldn't move the chain between the chain rings. My bike has SRAM Rival, so I did try to push it a bit further but nothing happened. I was scared I might mess it up further, so I didn't try to change it any further for the rest of my 12 mile ride. After getting home, I lifted up the bike and tried once again, just pushing it a bit more and suddenly it worked. Then, I wanted to test it again on my drive way, but when I shifted the front derailleur this time, the chain came loose. I put it back and took it for another short ride and everything seems fine now.

So my question is should I be concerned that I couldn't shift the front derailleur temporarily and also that the chain came loose? Do I need to take to my LBS for a quick check?

Sorry for the long post, if any of you experienced bikers did read it fully, please let me know. Thanks!

No clue. I do know that after 50-60 miles your cables might have stretched some and you might need some readjustment.

I don't really have a clue what happened but I doubt you did any damage.

If it were my bike I would ride it, and shift gently the first few times and then just ride it.

OK thanks. LBS from where I bought the bike will do a free two month tune up. So hopefully, if I don't see this issue again, I will bring it up during the tune up.

Keep an eye on it - if it does it again take it to your shop, they'll fix you right up.

And.. welcome to the Bike Forums.

Be careful. I brought my bike in for the 'first tune up' and then 20 miles later the front derailur fell off and ground into my front sprocket.

OK, thanks guys. I will keep an eye on it. Just was wondering if the chain coming loose was a common occurrence or not...

Regardless, in my opinion, take it back to shop, let them ride it, and get it fixed or adjusted. This sounds more like an improper assembly or initial adjustment issue. Cables should not be stretched in that short amount of time. My front deraileur acted up at the shop the day I bought mine and they adjusted it no questions asked. Should have zero impact on your freebie tune up. Good luck.

I ride w/SRAM components too. I would bet it is a result of cable stretch. This can easily be corrected...do you have barrel adjusters? If so, play with the front...turn slowly and continue to check.

Excellent suggesting.

I'd go a step further.

Check out YouTube for video on adjusting derailleurs. Got to the Park Tools site and read what they say.

Then ... play with the barrel adjuster.

If you turn it the wrong way you can turn it back, no problem. If you felt adventurous, you could tighten the cable from the clamp.

Even if you could never get it to work again, you could taker it back to the shop and have them fix it for free..

OK, thanks for the suggestion guys. I will watch the video on the barrel adjuster and see if it helps.

I would definitely learn how to make those adjustments yourself, but still take it into the shop since it's new if it's not too much hassle to get it over there.. A good bike shop will fix it no charge. But you want to know how to tweak those adjustments on your own if it happens in the middle of a ride, or when you can't get it over to the shop for a few days. The more you can fix your own bike, the more time you have to spend riding it, and the more money you save in the long run

Not common, but it happens. If I stop with my chain half off a front chain ring and then back pedal a little it will fall off the front. If it's happening a lot something needs adjusting.

You should absolutely bring it back to be looked at since you are unfamiliar with how to adjust these.

Your chain should NEVER jump off your crank - ever. If shifting throws the chain off, your stops are off. If you can't check your stops yourself, they need to.

Maybe a twig flew up or a pebble, which caused this, but that should take the mechanic 3 minutes to double check the stops.

If your stops aren't right and you throw your chain into your rear wheel, that's bad news.

Personally, I'd look up videos and learn. Mess with it, and get an understanding of how it works. But if you're not very mechanical, absolutely have them double check this.

Only happened once so far... but, I didn't take it for a longer ride since. Will test it out. Thanks.

OK, will try to check myself - I have done a few things with my car successfully, so hopefully I should be OK.

Either stretched or slipped.

On a RD, i can believe that stretch would affect the shifting, esp. on a 10+speed.
A front dr, however, i can't see being that touchy, even a triple.

Sounds like the cable was set too loose, or slipped a little in the clamp. I know i've installed a new derailleur, or new cables, and just set the clamps 'snug' while i make sure everything is lined up right, and then forgot to tighten the cable clamp. First time you make a hard shift,everything moves.

Excellent advice here. Sounds like the initial setup was off. The "error" that you made was nothing and nothing should have happened besides shifting the wrong derailleur. We've all done that from time to time.

Another important consideration is a relationship with a good shop. This is important for you and them. Get to know them and they will take care of you. For a LBS that's good business and good customer service. I have a LBS that I'm extremely loyal to and in return they treat me well. Watching a youtube video is nice but nothing beats a seasoned bike mechanic showing you how to do it, in person, on your rig.

+1...I am by no means a seasoned mechanic and agree that in person instruction is sometimes better than YouTube. Nothing worse then getting yourself into something w/the bike and not being able to fix/put it back properly

If it were me, I would take it to an LBS and have them look at it. This will also give you an opportunity to see if you like that LBS for future whatever. I also found that the guy at my LBS adjusts the cables and derailleurs by ear which I do not have the experience yet to do. Also a word of warning. I had my chain jump off the chain ring and I tried adjusting it myself. I am a newbie, but no matter what i did, i could not get the derailleur adjusted. I took my bike to the LBS and sure enough there was a bent link in my chain causing me to fail at the adjustments. The LBS spotted it in about 5 seconds.

I have been fighting this for months on my Raleigh ... tonight I will swap the chain.

Potentially, enormous thanks.

For what it's worth, the LBS straightened out the link with some vice grips without swapping the chain and it has been solid for a couple hundred miles now. I really need to start learning to adjust the mechanics of my machine, but I will need a repair stand first.

I got a $55 repair stand and I am Really glad. Cheap Walmart product, but it does everything any other stand can do ... and it folds up and hides away.

I figured I would swap the chain because if that Didn't fix it, no sense going link by link through the old chain.

If I find a bent link, I will ply it with pliers. If I mess it up I will blame you.
