Notes from MyBikeThing
The GP4000S II is Continental’s benchmark race tire — Black Chili compound for grip and low rolling resistance, backed by Vectran puncture protection. The 650c size is tougher to find than standard 700c, making this pair a solid pickup for anyone running a tri or TT bike spec’d for the smaller wheel.
Workshop Wisdom
On 650c tri/TT setups, check your rim’s bead seat diameter before ordering — 650c isn’t standardized across brands, so confirming ETRTO 23-571 compatibility with your rim avoids a frustrating mismatch.
