    Help a newbie, 2 x 10 - do I need to worry about cross-chaining?

    I purchased a 2017 Trek ex-caliper 8 and am really enjoying it. My question is, do I have to worry about cross-chaining like a 3×10? I recall when I was younger you had to be careful what gears you used. I'm a complete newbie when it comes to correct wording of bike parts and wording. Google has been a help lol. I just want to get the most enjoyment out of my purchase and not shorten the life the drive train if I can help it.

    By the book, you shouldn't crosschain, as you have the chain taking extreme angles and accelerating wear. With the 2x10 the width of the front is a little less and the angles not so extreme.
    That said, if you are riding and need that next gear which happens to be a crosschain, in my opinion, grab it. You riding a museum piece or are you riding to have fun? Crosschain won't cause immediate damage, so ride that thing.

    It'll shorten its lifespan. You'll also explode. Kittens will die. Horribly. Also, baby seals.

    I love this.

    Bad news: I lost the race because I didn't switch gears on the last climb.
    Good news: I saved some wear on my chain!

    On a properly adjusted drivetrain, at least, I agree that you won't have any immediate major problems.

    The way I always handle is is that I make the shift, and if it happens to be a gear combo with a chain angle I don't like (say, it makes more noise than I like, which is a good indicator that it'll cause more wear in that combo) and I wind up being there for awhile, then I'll shift around so that I'm in a similar or same gear but with a better chainline. So I'll switch chainrings and then bump the chain over on the cassette a couple cogs to compensate.

    If I only need to use the 'cross chained' gear combo for a few pedal rotations, for example, then it doesn't really matter.

    Use the large ring for anything and stay out of the two smallest gears with the small ring.
    No worries.

    Blaming results on your gear again? Good thing you saved a kitten this round.
