A question about Q-factor. If you put a straight edge on the back of the chainring, what is the distance between the ring and the back of the pedal eye? Most cranks are about 15-20mm; I need a crank where it's about 25mm. Sugino XD is too narrow as is TA Alize Track (I've measured them both).
It's to avoid hitting the chainstays on an unusual frame
Longer BB and some chainring spacers to take the ring back in (or mounted on the other side of the spider)?

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

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

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