Would love to have shot. What's the hub take-up like? Could you change the speed by changing your chainring/sprocket combo? </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=7908#post-79680 Sat, 28 Jul 2012 07:58:43 +0000 Dave 79680@http://citycyclingedinburgh.info/bbpress/ <p>As I was demoing at PY yesterday, I took apart my SRAM Automatix and changed the speed at which it shifts to be a more reasonable 15mph.</p> <p>In case anyone's interested, I <a href="http://mccraw.co.uk/sram-automatix-review/">wrote it up</a> on my blog...</p> <p><a href="http://mccraw.co.uk/sram-automatix-review/"><img src="http://farm8.staticflickr.com/7256/7654722010_c2f3fb4fa9.jpg"></a></p> <p>Knees much happier now! :) </p>
