Hi all -
I have a new Giant Escape hybrid which I've put about 60 miles on these last 2 weeks. Last ride, I noticed when I switch gears on the rear cassette, it skips gears when downshifting. I have the stock shifters on the bike (SRAM X.4 Trigger), so there is a lever you push to downshift, then a button you click to upshift. Upshifting is fine, no missed gears.
From browsing the web a bit, my newbie guess is the cable tension has slacked off due to the new cables stretching a bit? Is this something I can adjust using the barrel adjusters? I get a free tune-up at the shop I bought it from, so if it is something more involved I can take it there, but I am learning how to fix stuff and while the drivetrain is above my pay grade right now, I'd be more than comfortable with small adjustments (just don't ask me to take it apart then put it all back together again!)
Also - and sorry here for the horrible description - on the front rings, I initially had a problem where I would push the shifter lever (the action is opposite from the rear rings - on the front, the lever upshifts, the click button downshifts - please, if there are better terms to use, let me know) and the chain wouldn't quite make it onto the bigger ring. I quickly realized if I pushed the lever in a bit more and held it for a second, I would smoothly shift gears. So that's what I've been doing with the rear, assuming they work the same as the front. Maybe I am pushing the lever in too much?
Again, sorry for the awkward description, hard for a newbie to put this into words
thanks for any insight/advice you can offer
