Hi all hope this is helpful to all for accurate alignment of rear wheel

Drive chain following chain adjustment for slack (50-60mm) when on centre stand. Rear wheel axle nut tightened to 95 to 105 ft-lbs.
The laser alignment tool I got from Bikesmart for £66.90 inc vat and delivery as they were cheapest in UK. German made quality tool this is the magnetic version as rear sprocket on Pan is steel.
