Had a really long day at Ironman this year... 5 years of bike hassles in 180kms.... Best be forgotten Nonetheless - this got me thinking. Why does no-one ride a 1-11 setup on a TT bike? Answers to my own questions would be: minimal weight saving (Cabling, derailleur, chainring, shifter etc...dont add up to much) Any weight saving would be reduced by having to add a chain guide Gap between gears is too large. Optimal cadence is in a very narrow range of maybe 5 rpm (not sure what Sheldon Brown says about this) My situation further compounded by running Osymmetric (not Rotor etc...) front rings. Thoughts?
