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.
