The uphill time trial – from Bourg d´Oisans to Alpe DHuez – features 21 bends, climbing to 1130 metres.
Jan Ullrich from T-Mobile and Tyler Hamilton from Team Phonak Hearing Systems will ride the TT with light-weight hand-made tyres treated for hours with Conti’s special tuning liquid.
"The interplay of fluid with the tread pattern concept leads to a clear improvement in rolling resistance," claims Continental.
"A field study with the T-Mobile team demonstrated that the tyres rolling resistance dropped by 15 percent thanks to the chemical after-treatment."
