Can I run a 9 spd Shimano mtn cassette (something in the 34 tooth range) with a long cage rear derailleur even though I have Ultegra STI 10 spd shifters? I have a rather hilly century + ride coming up and want to save my knees some pain. I have a compact 50/34 and normally run a 12-27.
[quote="nerdag"]10sp brifters will work with 9sp rears if you use the B Cable anchoring position: [url="http://www.sheldonbrown.com/dura-ace.html"]http://www.sheldonbrown.com/dura-ace.html[/url[/QUOTE]I won't argue with The Captain! 😉
