Ignore the speed fascists - I knew exactly what you meant and I'm guessing a lot of others did too. It wasn't like you were claiming to have done a stage of the TdF at 22 mph. I travel for miles at a time at 20mph+ and I'm just cruising along .. no effort, just turning the pedals .. but then I have fitted some aero bars, the road surface tends to be as smooth as and I know a lot of the time there's a very, very slight downward slant on those routes were this happens but that doesn't make my desire for aero benefits any less real.
Anyway there was a study published here on bike radar that showed that aero bars/position helped a rider to a large degree and that an aero helmet was the next best thing on the list that would improve a riders speed/time and that, I think, the effect of the lid was approx half off that offered by the aero bars/position.
Well my experience with clip on aero bars was pretty awesome so if I get half the effect with an aero lid again I'll be one happy bunny. The only problem is they are bl**dy expensive so hence my wait.
If you do go down the aero route please tell us how it goes - cos I, for one, love the idea of getting speed for free.
This nonsense really doesnt warrant a response however in the name of common sense, here is a brief reply.
How many commuters have you seen decked out in skinsuits and aero helmets riding TT bike to work?
The aero gains you are alluding to in the study you read, it was about gains per £, are aimed at competing tine trialists who may benefit on a competitive front from saving a few seconds over a 25 mile time trial.
Bingo! Thank you.
