I rode up Col du Tourmalet on Friday with a group of guests from the Cycling Lodge. It was a not unpleasant day with temps in the high teens down in the valley and 6c at the summit. Just as I was starting the descend it started to snow a little. Winter is on the way.
I used one of our 2016 model Lapierre Xelius SL 700 with Di2. Sweet bike. Super responsive and super comfortable.
