Looking for a crankset to fit a 2017 CAAD12 - preferably a 50/34. Bike shop tells me I need a 89mm spindle length.

89? 109 more like.

Yeah I'm only finding 109 out there... I guess the bike shop is wrong :/

They probably don’t know the ins and outs. It’s a fairly specific part so don’t hold it against them too much.

You’ll also need the spacers and bearing shields and whatnot. If you find the exploded diagram for hollowgrams it will show you the part numbers.

Getting the Si crank will be easy and cheap, the Hollowgram cranks less so.

Hi, thanks for the info - much appreciated. They've been pretty helpful so I won't give them a hard time!

Cheers for the heads up about spacers & bearings. Just found the diagram so I think I know what I'm after now.

I think I'll just look for the Si one for now. Thanks.

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:
![](https://www.google.co.uk/images/srpr/logo4w.png)
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.
