Dessus new zipless aero jersey: is this really the “fastest” jersey out there?

8 to 12 watts increase just by wearing their jersey?  Bull Schit!!!!   If this is true then the average speeds at the TDF should increase each time some company comes out with something new that gives the rider and additional free watts, but we're not seeing those increases at the TD, in fact, over the last 60 years the average speed has only gone up by about 2 miles per hour, but the main reason for that speed increase is that the daily rides have gotten shorter, so the TDF race is 300 miles less than it was 60 years ago.  All this technology from steel bikes to CF bikes, to aerodynamics, has done nothing!  And yet we're supposed to believe that some jersey you're wearing is slowing you down so you better buy this fancy expensive one.  LMAH!!!

We've only had one speed spike at the TDF in 2005 but that was only good for 1 km/h, and that was because everyone was doping.  In 1960 the average speed was 37 KM/H, or 23 mph over 2,573 miles, in 2014 it was 40 km/h or 25 mph over 2,270 miles.   All done over 21 stages.

If you want me to believe all this saving watts crap is for real then you need to show the proof at the TDF, according to my best estimates all the watts that the industry is saving from aero bikes, helmets, shoes, pedals, jersey, rider position, etc etc etc we should be doing at least 5 mph faster than in the 60's.

We're just buying into the traveling medicine man show.

Shame they can't export any to Europe without loads of fees and taxes....otherwise I might be interested.

As tested with the Body Rocket system....That was was enough for me to ignore.

When are you going to stop writing this BS?  Please get someone who knows what they are talking about to write these articles, something CANNOT be X Watts faster, the Watt is NOT a measurement of speed.  Writing things like that just destroys all credability of everything else in the article, it really just points to the review being a manufacturer's worded advert and not an independent review of a product.

Can i hear you say jeasus, jeasus was sent to save your souls,

I've got one of the gen1 Dessus jerseys. It's a really well made jersey, fits great (despite me having a bad shoulder that wants to pop at every movement) and the only compromise for me are the rear pockets but it's no big deal. 

I think design is genuinely something different, it's not a massive name but it's designed here in the UK and the fact it boasts aero benefits is a bonus as I'm always chasing my own PBs.

I'm pretty the UAE team had something like this a while back.

So it's a t-shirt then.

Sounds like they could have saved a lot of time by adding the word 'tight' before the word 't-shirt'.  

Read great piece once upon a time, and for the bog -standard cyclist like me, with avg speed 14-16 mph over 30 -60 mile spins, there are only 2 things that make a significant difference to the time it would take me to cover 25 miles / 40 km - 1. more training, ie get fitter and stronger  and 2. a more aero position   ie tri bars  - -            A 3 kg lighter bike might save me 20-30 secs, an aero bike something similar  ,  dunno about an aero jersey but can't imagine I'm going anywhere near fast enough for it  to have a tangible benefit. Anyway, i'm getting older, so I have come to terms with the fact all my PBs are set in stone,  and  now i concentrate on enjoying myself on the bike
