    "T" refers to the number of teeth on the front chainrings or rear cogs. What are you looking to replace? How do you feel your setup worked for you?

    the big ring on front gear seemed to be worn out. since i purchased this bike used locally like 3 weeks ago. bike is awesome, did some climbing that ive never done before. its just that i can tell that its a bit worn out, in fact i already ordered a new chain for the bike. i was thinking of changing the front ring.

    Are you looking to replace just that ring, or go to a single ring system? How many teeth? It should say on the ring somewhere...anywhere from 22-38 or so. What cranks are you running?

    Pretty easy to replace. Lots of companies make rings that will work as a replacement. Sounds like you just want a replacement, not a change in size, right?

    No, that ring doesn't have ramped teeth. You'll have a hard time shifting to and from a ring with no ramps. Keep looking, I'll look too.

    I can't think of a single benefit of using a 34t big ring on a 2x system. You lose top end and gain nothing on the low end.

    Blackspire is a good company. I think their superpro is their ramped chainring.

    Yep - so much gear. This whole forum is pretty much dedicated to parts and gear.

    Unless you've been slamming your chainrings into every rock and log in sight, or you've been riding several hundred miles a day in those three weeks, you haven't worn it out.

    Adjusting your gearing to suit your riding style and terrain, ok, I get that. But you haven't worn your chainrings out.

    Usually, a good sign that the chain ring is worn by looking at it (and you will get used to that every time you clean your bike). Do the teeth look "sharp" or are there plenty of "rounded" ones?
    If the person before you used the bike for downhill, chances are they didn't pedal much. They could have bent the front ring or smashed it on rocks.
    Most bikes, the rear goes out first, then the front.
    Chains also stretch.
    Unfortunately, putting a new chain on a really well used rear cassette and worn out used chainring can give you even more problems.

    Recommendations:
    Replace your chain
    Replace your chain ring if it looks worn
    Think about replacing your rear cassette if it looks in bad shape.

    As you put a whole lot of miles on your bike, change the chain before everything else gets too worn out. The chain is cheap and will save the rest of your transmission.

    How did you isolate it to your front ring? Was your chain slipping? Did you check the cassette? I know you mentioned getting a new chain and that's a good start. This may be a good time to get a bash guard if you don't already have one.

    OP: Without meaning to be rude, as it's not my intent. Are your cross chaining? using big ring at the front and big cog at the back.

    i slip on last ride while going pretty fast on bumps and rocks, a little bit of speed and i want to pedal more, i notice that im slipping, to the point of the chain bump to smaller ring (front) without me shifting it. im still a newbie, i have 60 rides under my belt well over 350 miles on 4 months run, i can tell the difference on my hartail and this one in terms of pedalling. i usually use biggest ring on front and 3rd biggest on the back (i dnt shift on rear since i refuse to learn! lol i just feel the bike) i need to learn more
