Straight blocks (11-20. 11-21, 11-23) are fairly standard and look like corn cobs to the hoi polloi.. Remember most of the early stages are flat and lower gearing is not needed. Note the cadence, typically in the 80-100 range, and of course the speeds, which are in the high 20's, occasionally low 30'smph. Their small CW will be a 42t rather than 39t most doubles are equipped with, at least until the mountains when most go to 39t.
The torque these guys can generate is phenomenal. Few pros in the TdF, Giro, or TdS generate less than 0.5 hp average. Lance types are in the 0.75hp range. Steve
