Speedfil Users - Like it? Hate it?

I am just looking for some thoughts from those of you that use the Speedfil aero bottle. It seems rather bulky and looks like it could cause some significant drag. I know their website claims it was developed in a wind tunnel and that it has aero benifits but every triathlon product on the planet claims the same thing. Just looking for some real world experience.

Thanks!

Thanks! Sorry I didn’t realize this question was already out there.

Don’t do it! Just say NO!

Love it. On hot days I don’t drink enough unless the straw is right in front of me. It may be overkill on shorter rides (under 40km) but I don’t care…
I tried the Profile Designs Aerobar bottle (its good for shorter rides), Xlab sonic wing system (didn’t work for me), regular bottles (actually, these kinda work ok). Speedfil is still my fave.

It’s great but make sure to clean it thoroughly and immediately after rides.

I got the Speedfil this season. A few weeks ago, I raced with it for the first time. It was nice to be able to drink at my convenience and stay aero. I also used the Infinit Nutrition system that puts everything you need in one bottle. I my opinion, for HIM distance and Oly dist this is a great way to go.

I like it, I haven’t tried the in bar solutions so I can’t compare the two but it definately looks better.

Thanks for all the feedback. I decided to order one today with the new silver cover. I have always had a problem hydrating properly on the bike so hopefully this will cure my problem.
