No issues for me. I'd be very interested to see a picture of the damaged seat post and X-Lab's response to the issue. In the bottle is a sports drink concentrate that I take a pull from ~2x / hr. The BTA gets refilled with water at the aid stations.

take a look at this thread

Yeah there are actually a couple methods we have seen strapping a Mini Bag with a Delta on the back.

Best method where it attaches to the seatpost. This athlete put some longer velcro on the top to make it go completely around the seatpost.

This athlete strapped the top strap onto the cage. Although it works, it puts a lot of pressure on the arm of the Gorilla cage and we don't recommend it as it could very likely snap the arm. As soon as the Aero Pouch 300s are available this athlete will be switching :)

Thanks Candice

What if I got the Stealth Pocket 100 and flipped it up vertical using the two Velcro straps to the seat post with the tapered in pointed down and the headset strap around the saddle rails?
Seems like that would work. It may look odd, but on the longer journeys in the middle of nowhere vanity doesn't really matter a whole lot :-)

edit: or I suppose I could just attach the Stealth Pocket in its intended location if having something on the top tube doesn't bug me too much :-)

Love the look of that Candice, question, does the Aero Pouch 300 have to be over a Delta type carrier, or can I use that with my ziptied Gorilla cages?

You might try the Mezzo Bag. The straps are nice and long, easily goes around the wide aero post of my S5. Holds a ton, but can shrink nicely with the strap that wraps around the center of the bag. I will use this bag by itself, or if it's a long training ride and I want two bottles behind, I'll hang it under a Carbon Wing with 2 cages attached.

That particular customer's issue was involving the Delta Sonic & the seat post, nothing regarding the X-Strike (the CO2 holder). In regards to the damage, although there was no definitive conclusion (due to not hearing back from the customer after our suggestion of getting a replacement seatpost), the customer's seat post looked severely worn, much different to the multiple seat posts we have in house, and therefore the level of wear could have assisted in the Delta Sonic becoming loose. Cervelo is very good at replacing cracked seat posts. Feel free to peruse the thread that the poster above referenced. With our experience if you have a seatpost that looks like the ones I posted you will have no problems.

We are working on a solution to enhance the sturdiness of the mount, but this is more of an enhancement, it is not required. We have a few top pros that use this carrier and have had zero complaints on cracking seat posts. We actually started selling Delta Sonics mid-2012 and have only had a couple complaints on cracking. Most of which we concluded were for either severely worn seat posts or what looked like hitting it with your leg due to mounting/dismounting. We were able to tell this from the direction at which the crack appears.

Top tube is definitely the best place for the Stealth bag, but you can also do your first suggestion. Before we came out with the new bag we recommended a Rocket Pocket with a similar setup.

The bag is meant to be bolted down, there are no straps on the bag, so yes it has to go over a Delta type mount. We are still performing some rugged life testing on the bag and will suggest adding zip ties to the testing, but I doubt it will come about that we actually formally recommend it as we have seen over and over again zipties breaking and you end up losing the whole lot.

Thanks
I did a quick web search for images and found a few bikes with the Rocket Pocket XL mounted on the seat post and saddle rails. I think it looks pretty good and should serve my needs.

Cool. Yeah depending on what you want to store back there will decide the right bag. For Rocket Pocket you can fit a tube, levers, CO2, Inflator & Patch kit. The Rocket Pocket XL will fit a tubular ture, levers, CO2 and inflator.

Hi Candice, thanks for the info. It is my opinion that the clamping system employed by X-Lab isn't commensurate with the product cost, hence I'll look at a different option right now. Whilst pro endorsement is great, they often have different requirements to amateurs, i.e. less of a focus on durability. A knock mounting/dismounting is probably an unfortunate reality.

Once again, thanks for the feedback.

And appreciate your opinion, everyone has their own!

The Delta Sonic design was in coordination with Cervelo and with the concept that we had at the time we chose the best material, stainless steel and the bend is rather difficult to do. Thus the cost. In regards to pros and durability, from my memory without looking at the actual orders, Caroline Steffen and Rachel Joyce have had their model for about a year now. The only thing we switched out was the cage because we changed the look of it. I referenced the pros because of the number of races that they do, the amount of training they do, the travel wearing on the product and that these products are a path to earning a living. Not saying an age grouper doesn't do this, but it is a good example.

One thing XLAB takes pride in is durability, stability of mounts and reliability. To this day I see people using our Saddlewing that we introduced in the early 90s and 1st/2nd gens of our Carbon Wing, even flatwings! We bring in thousands of pieces of hardware a month because we care about the type of hardware that is used. Often times people come up to us and say "I should have bought XLAB in the first place". That is why we are here, to help our customers so they do not have to worry about losing hydration and we can continue to support them for years to come.

I purchased both the Stealth Pocket and the Rocket Pocket XL. I posted some pictures here (sorry I have not cut and cleaned up the Velcro straps yet).

http://thecyclingaddiction.blogspot.com/...10/xlab-options.html

I have not decided which bag to use behind the seat post yet. Both fit nicely even though they were not intended for that location.

There you go! Nice overall race setup. Let us know which one you decide to use!

Candice, I am really interested by the Aeropouch 300. Any ideas when this will be out? Also, I currently ride a sitero saddle with a bolted saddle on the integrated mount, will I be able to use the Aeropouch 300 (say with an xlab bottle cage bolted to the sitero).

thanks for the feedback

I am expecting that we will release it in about another month. Just doing some refinements to it. As far as mounting the pouch with a Sitero saddle, let me check on that and get back to you.

I don't have time to read through this whole thread, so I apologize if this is repetitive...

The key to single bottle placement is to get that bottle as close to the saddle (and, therefore, your arse) as possible. This will almost always result in a reduction of drag as it fills the wake you're leaving behind (no pun intended). Zip ties are great, but both Xlab and Speedfil mounts can get them close too.

The moment that bottle moves out from the saddle, another cylinder is placed in the wind thereby increasing drag. Same goes for bottles hanging between your extensions on the front. If it's out away from the head tube, well, you've just created two head tubes. No good. Up against the head tube...very good.

crap, so what you are saying is the Xlab Carbon wing is like dragging a parachute behind you?

PS after IMAZ I will be giving you guys a call, I need to get refit, and following your posts on ST has me convinced that you guys know what you are talking about...

Not necessarily. You just need to set up as close to the saddle as possible. Two bottles, which we really haven't tested enough of (we tend to take them off only to put something else back on), tend to be more benign for some reason - neither a help nor a hindrance. I plan on conducting some more extensive testing on all of this with several different riders in the very near future.

Now, if only there was some place I could post all our independent test data both using the Alphamantis system and the wind tunnel. If only some web site could be planned for the future that might allow you to filter through theses results to help you make informed decisions. If only...:-)[/img]

Im assuming that is a tease for a new site, of course that didnt stop me from scouring your site to try to find it...

I did check the twitter feed, and started to follow. Already looking forward to a fit!

Assuming one will be using three bottles, a BTA bottle for hydration, a second bottle for flat repair and a third bottle for hydration what in general would be the more aerodynamic solution assuming a Cervelo NP3. A bottle on the downtube and a bottle tucked in tight behind the saddle, or no bottle on the down tube and a dual bottle setup behind the saddle?

Dual bottles behind the saddle. You want to make sure that they are as narrow as possible, not widely spaced behind the saddle.

I saw one pro testing two BTA bottles (placed back to back), so that might be another option.

Candice, any idea of the ETA for the new aero pouch 300?

Hey frenchieTT, I thought the bag was further along then it actually was. Our first prototypes didn't meet the 110% quality we want in a ground-breaking new product. As of right now I can tell you we are doing further internal testing on a new unit. I will make sure to keep everyone updated as it gets closer to shipping. I can assure you this pouch will be worth the wait and I am not basing that off my bias views, but the reactions I have received from the media, consumers & our athletes!
