Quite literally ... [URL]http://www.sweller.co.uk/sob/guzzi.html[/URL] Needed the front wheel's bearing carriers machining to get the original two piece brembo discs to fit the T3 wheels and forks. I was really surprised that the spoked wheels were appreciably lighter with tyres, bearings and discs than the cast alloy /without/ the discs and tyre. Still needs a little work with a file on one of the spacers but the front wheel is only off centre by 1mm.
