I have a 2015 Vitus Sommet. Bought it as a frame-only an built it up myself.
A month ago I thought I would get myself the upgraded Debonair sleeve for the Monarch on the back. I’m going to the Alps later this year and though a bit more volume and tuneability would be useful.
The new air sleeve arrived last week, and I was surprised to see it appeared identical to the one already installed.
Imagine my surprise to discover that the frameset was sold as the frame-only version of the “Pro” full bike, so already includes the Debonair sleeve. However, this being very early on in the Debonair’s history, there is no visible label which identifies it as such. All the modern Debonairs have the logo on the Plus canister. Mine doesn’t, only on the label which is neatly nestled and hidden within the seat tube.
So, now I’ve got a really handy spare air sleeve, just in case, I dunno, mine gets hit by a very well aimed, heavy rock?
