TT Bike single front chainring

[Red_Zebra]

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?

I am seriously considering this option - my frame has been damaged around the front derailleur, so removing it altogether is my thought....

I want them to develop a wide/narrow chainring for TT bikes as well. If they could make a 53, 54 or 56, then I will buy it. Most TT's are anyway on flattish roads and how many people shift up front when using that bike.

Ironman 70.3 and IMSA are both very hilly courses
