does anyone know if trek bikes take a trek specific chainring? this is what the guy in the shop told me but i don't really believe him. if this is a lie would i need a shimano type a or type b. it's a 53t for a double i'm after.
cheers

it says 130-s. for double shimano you need type a or b and they're not interchangeable apparently. it's not actually my bike so i dont know much about it just trying to find out for a friend. cheers for the reply gogosama.

Never heard of a Trek specific chainring, you should be able to fit any old chainring with a 130bcd, I think an A type chainring goes with a 42 inner and a B type goes with a 39 inner but it shouldn't make that much difference according to Sheldon

Edit, prob find a better shop if that's the advice they're doling out.

Formatting Help

Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.

Tips:

Create headers by underlining text with ==== or ----

To *italicise* text put one asterisk each side of the word

To **bold** text put two asterisks each side of the word

Embed images by entering:

That's the hard one: exclamation, square brackets and then the URL to the image in brackets.

* Create lists by starting lines with asterisks

1. Create numbered lists by starting lines with a number and a dot
