Thanks for the recommend, I need to replace my Tyre Pressure Sensor batteries soon and fit some new boots for my France trip in May.
Just ordered a pair of Michelin Pilot Road 4 (Trail) in GSA fitment from tyre leader for £173.68 delivered (just seen the same pair on eBay for £209 with black circles). After hooning around on Metzeler Tourances for years, these should be interesting.
