TT bikes are disabled for this scratch race. Over 1 lap of Ocean Lava Cliffside Loop (19.2 km), our physics model makes the Specialized Tarmac SL9 with Shimano C99/Disc the fastest legal combo, finishing in 34:48 (~33.2 km/h).
How this race tends to play out
A single lap of Watopia's Ocean Lava Cliffside Loop - 19.2 km with 156 m of climbing spread thinly rather than stacked into one wall. Nine tenths of the lap is tarmac, and the short dirt, wood and cobble stretches together come to under 2 km, not enough to pull the answer away from road wheels. Feather and Anvil are the powerups.
