At some point you may not want to use the canned attributes.phtml groupings that magento provides, or you just want to cherry pick which attributes to show on your product listing page template/catalog/product/view.phtml
$_product = $this->getProduct();
//For the attribute bike_specs_rear_shock
$_product->getResource()->getAttribute('bike_specs_rear_shock')->getStoreLabel(); //label
$_product->getbike_specs_rear_shock(); //value
