Does the twitter link shortening service reduce link value (strength).

[WebRiverGroup]

We have many SEO team members that use Twitters link shortening service, will this reduce the strength or value of the page to be indexed? I ask this cause the displayed URL isn't the actual page it is going to and would like to make appropriate changes to improve our company's SEO

For example:

http://t.co/zHu8vIcjPx  is going to page http://4wheelonline.com/atv/QuadBoss.107503

Thank you for your assistance.
