Am I going to die if I mix a new shimano IG51 6/8speed chain with a new Shimano Ultegra 6600 10sp front inner chainring? Will the chain be too wide for the narrower 10sp ring or am I overthinking it?
Cheers!

I've had a 1/8" chain on a 39t 10sp shimano chainring before on a fixed setup with no issues

Cheers, that's what I'd hoped was the case. I guess mixing a thin 10sp+ chain on an older, thicker chainring would maybe cause slight issues.

Probably be ok, are you running this single speed?

If gears, you’d really want at least a 9 speed chain for a 10 speed cassette

Well it's a bit of a triggers broom ;)
Old school Shimano XT 8sp cassette, IG51 chain and DA 7410 chainset with later 10sp rings. (not yet fitted hence question). All parts are nos/new...

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
