Just for fun I thought it would be nice to post all new aerodynamic bike parts here together with the claimed advance in time or watt over the non aero counterpart.

Personally I am quite a fan of the aerodynamic revolution, but I think these claimed advances in time or watt are silly to say the least. That is why I would like to see if we can get a ridiculous advantage in time or watt.

To start of, here are a couple:

- Bontrager's new Kamm Tail handlebars; will save 23 seconds per hour at 40km/h
- Bontrager R3 TLR tubeless tire: will save 8 watts compared to other tubeless tires
- TREK 7 frameset: will save 25 watts or 120 second per hour at 40km/h compared to previous Madone series

Saved so far: 143 seconds and 33 watts

Happy hunting! :beerchug:

Id rather look at the power saving than time.

Ie, your saving roughly 38 watts at 40km/h

#1 Slam your stem
#2 Ride the drops

(Honestly though I think it's quite silly to claim savings without mentioning the conditions under which those are achieved. Claims are just marketing, documented reproducable/verifyable conditions are needed for a scientific approach).

Aside from the bike, me losing 20 lbs would be like gaining a lap or two...

I am not sure if all these power savings are additive anyway. I think they should be ignored unless you have a eind tunnel and test how different products work with you on the bike while you and the bike are rigged up with various air flow/pressure sensors. Could be the ultimate weight weenies/aero toy couldn't it.

Don't forget the peloton surrounding the test rig.

Because an improper fit is definitely the best approach.....

I've actually heard of aero paint jobs. No joke.

Ridley makes the "aero paint" hahaha

"they apply a textured surface treatment for boundary layer control. Ridley calls it "R-Surface paint", and our affectionate shorthand here is "aero paint". These thin stripes of texture are amazing. They purposely trigger a known amount of turbulence that re-energizes lost boundary layers, ultimately re-establishing laminar flow and minimizing drag. In other words, they carefully create an airflow mess in order to make an unprecedented cleanliness. Airflow control is why you see vortex generators on jets, and why you see dimples on golf balls. And it's exactly what Ridley does with their R-Surface paint."

Fisher, if you put a spoiler on a bus, it's stil a bus. Fit is not a constant, a low position can be trained just like other aspects of cycling. That said, I'll readily admit that my remark was tongue-in-cheek, which I had hoped would have been made apparent by the explanation below the "slam it" part.

Hah!
For the big (non-UCI) TTT last weekend I brought out the works:

Lycra shoe covers
Taped helmet holes
Cronosuit
60mm rims

It didn't help. I froze to death in the wind and the rain and had to let the team go 40 km from home. :lol:
