This was never going to work but someone asked about 650x47 in the Mason Resolution frame:

Badlands setup was 700x50 GK SK+ which actually fit better than the 650x50 because they're on 18/19mm rims rather than 23/25:

Yeah, of course it does. The top pulley reduces the angle by 1/12th, and the bottom reduces it by 3/14ths. I think - I might be a bit too stoned to be sure.

Bigger pulleys, less angle. There's more wrap than you'd get with a longer cage like the upgrade kits, but I'm pretty sure that counts for jack shit, it's just the articulation angle that matters.

BTW, these pulleys I bought off eBay specifically to jam in my Red derailer, which took them with no modification. Different story with the Dura-Ace number, had to cut off one pin and go more than halfway through the other one.

That was my point. You've got bigger pulleys but less distance between them so I wonder how much of the larger pulley benefit it's negating. I want test data...

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

> Quote text by starting lines with >

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

```
Your code goes here

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

If you upload more than 5 files we will display all attachments as thumbnails.
