[Closed] Sram Apex & Rival - how do they compare to Tiagra and 105?

A little bit late with this but tour's groupset comparison might be quite helpful - [url= http://www.tour-qtr.com/epaper_4_2011 ]http://www.tour-qtr.com/epaper_4_2011[/url]

And my 2 cents - I found using the brake lever for shifting on shimano road groups horrible. Might have been because I'd only ever used mtb shifting previously, but I really didn't get on with it. Especially trying to brake and shift at the same time. People don't seem to complain about it much though, but I found I much preferred Sram road groups primarily because of this. And from what I can gather apex through to force don't really have very much differences apart from weight savings, and the sram groups are already lighter than shimano's offerings by quite a bit.
