Bit of a long shot, but as above!

In retrospect I was a bit arrogant in my chainring choice given the amount of time I spend in the Kent hills. Probably seen around 1000km so in very good nick, looking to trade for equivalent Ultegra 50/36, or equivalent (oval chainrings also considered)

Cheers

Just get a 36 chainring?

I figured the jump would be too big, is that not the case?

Yes

Yes it's too big or yes that's not the case?

Too big a drop.

I believe 14 tooth difference is what is listed as the limit.
You might get away with maybe 1 or 2 more than their limit but 17 😲

OK thanks. Also now thinking a new cassette may be a better idea, any implications of upsizing there with current chainset?!

I'm on 52/36 R8000 which shifts great. Is 1tooth more going to make it explode?

No, it's not.

I've used a 53/36 combination with absolutely no ill effect in t'Alps, and still run it with good effect to this day.

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

Just like Github, a blank line must precede a code block.
