We will definitely consider such a version. As mentioned we have already been using a thru-axle up front as well, so are open for evaluation and testing of the various options. Thanks for the input though! We also already have wheels with x12 as well, but are trying hard to find the "best" performing solution for the current market situation.
First things first for now though and like that we are momentarily heavily working on the rim brake version of the "Vial Evo
". Sadly it had not panned out just quite with the promised pictures of the first production frames up until last weekend. According to the current schedule the frames should still be finished this afternoon, to then be painted tomorrow, so that I should be able to take the first 'spy shots' on Thursday.
As a small technical excurse to shorten the waiting time and to give some more insights on the hidden constructional “gimmicks” (that would eventually go unnoticed otherwise), I have been grabbing a set of rear stays for demonstration.
As one probably still easily spots the left and right chainstays are asymmetrical: the left side being a lot larger in diameter than the right one. The basic shape of the chainstays appears to be quadratic, but sports rounded “edges” for an improved force flow and reduced possibility of wrinkles respectively lower resin aggregation in the edges; however in fact the stays go pretty much towards a triangular cross section.
As one can see on this picture with the rear view of the chainstays the asymmetry is not only limited to the volume of the respective stays, but also applies to the general shape of them: The right side has a more distinct vertical ovalization in order to counteract the chain tension on this side.
On its outside there also is a visible bulge to make room for the small chainring without taking too much volume out of the chainstay – as one can still easily see the general dimensions of the stays are still rather traditional and slim.
The stays are systematically reinforced with high modulus fibers (from motorsports) on the outside, on the inside there are special elastomer layers embedded into the laminate (a patented process from our motorsports engagement where it is applied on almost all structural parts) which effectively dampen vibrations and thus boost both fatigue resistance as well as comfort (without affecting lateral stiffness).
