I most likely should replace the acera but I want to see if it is even worth adjusting if there are anyadjustments to make.
The problem is: When I shift from 6th to 5th or from 5th to 4th the rear derailleur seems to get caught. It will not shift to 5th gear or if I am in 5th it will not shift down to 4th unless I tap on the derailleur or hit a bump as I am riding. The shifters indicate that I am in 4th or
5th but the bike is actually in 5th or 6th depending which gear I am shifting from. Is there anything I can do to adjust this problem or should I just replace the derailleur? Keep in mind this is a new bike wth all new components on it. I dont want to replace anything yet but if I have to, well then I have to.

sounds like your cable tension is off. adjust it with the barrel adjusters. look it up on the park tool website. oh, and yeah you should replace the acera

iron bike - Never assume when a rear deraillure is doing something strange that it needs replacing. 90% of the time its just an adjustment that needs made.

Yes, it is mostly likley cable tension. This page explains it well, you do not need any special tools besides a 5mm Allen Key or 9mm spanner. You may need a Phillips head screwdriver aswell to adjust limit screws. HERE

Oh and no you dont need a new deraillure, but if you want lighter, better quality and better shifting and upgrade would help but is not nessesary.

Good Luck

thanks for the replies.

I messed around with the adjustments all night last night & it still seemed off. So being tired of the problem I broght it to a friends shop, he is going to overhaul the whole bike since I haven't had a tune up on it since I bought it a couple months ago, & I have well over 100 miles on it. I am going to wait on upgrading the derailleur for now, it allways shifted smooth & quick when I first got it so I will wait until next yr to make that decision.
