I need some help with my bike and I can't find the solution in my Zen book.<br><br>
I have 3 rings up front. When shifting from the big chain ring to the middle chain ring, it will more often than not, not engage. When I shift again, it goes straight into the small ring. Shifting from small to middle, middle to large, is not a problem though. I recently got a new chain, wondering if that is part of the problem. Any suggestions before I have to drag it to the bike shop?

Not engage? Do you mean it doesn't fall far enough to the left or it gets stuck between the big and middle CR?<br><br>

It gets stuck between the big and the middle, so then if I just try and tap my shifters, it heads straight into the small ring.<br><br>
By the way, a unrelated question, in the Coach Troy spinnervals, when he refers to big and little chain rings up front: most people only have two right? So for me, little means the middle???

Yeah, like at Starbucks "tall" means "small"<br><br><a href="http://www.illwillpress.com/sml.html" target="_blank">Foamy the Squirrel - Small, Medium, Large</a>

<span style="font-family:'Times New Roman';"><span style="font-size:medium;">Three rings means that front shifter must be indexed. Check to make sure that shifer is properly lubricated. It might be sticking when you downshift from the large to middle ring.</span></span><br><br><span style="font-family:'Times New Roman';"><span style="font-size:medium;">Dan</span></span>

2-gear front rings are usually around 53/39, so I'd find the 2 closest to those numbers and adjust your rear accordingly if your's are close to that. I'm usually off a couple gears off in the back from Coach Troy anyway depending on how my trainer is deciding to act that day. (yes it varies, not it's not in my head)

If you just had a new chain fitted, take your bike to the bike shop - sounds like they just haven't tuned it properly <img alt="sad.gif" src="http://files.kickrunners.com/smilies/sad.gif">.

It's possible that the chain is incorrect, you can take a magnifying glass and read the model number stamped on the plates and goodgle it to see if it is 9 speed compatable, most generally are. The symptoms you describe make me wonder if the cable is binding a little somewhere, perhaps where it runs under the bottom bracket. follow the cable back from the front derailer and inspect the little track it runs through, then grab it as it runs down the down tube and pull gently to see if the action is fairly smooth.<br><br>
If the bike does this durning a ride or race, you can often get it to complete the shift by reaching down and grabbing the derailer cable and giving it a pull, then let it snap back, just pull it an inch of so. This is an old mountain biker trick for when the bike is all full of mud and ice and refuses to shift.
