Following along the same lines as the Ballig bridge thread ,over the years there have been quite a few changes and improvements to the TT course , are there any in particular that have made a significant difference to lap times ? I know this is not a easy thing to answer because there is a year between each meeting the bikes improve as well .
A friend of mines dad reckons that quarry bends are straighter than they used to be, or is this just a visual thing because the edges are clearer ?
