I'm wanting to upgrade a bike that has 105 10-speed front and rear mech to 11 speed Ultegra mechanical. Anyone foresee a compatibility problem with the GXP BB and cranks?

It currently has rotor chainrings, assuming the crank can remain unchanged do you reckon I can get away with keeping them or are new chainrings needed?

Won’t be completely perfect but it will work fine. 10 to 11 speed in terms of cranks and rings are only slightly different and one will work with the other

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

For syntax highlighting, surround the code block with three backticks:

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