Hey folks - Let me take a minute to explain these numbers and where they came from. As part of our rim development and testing, we do impact testing on a machine we built in our test lab. This constitutes impacting a rim with a square edge weight repeatedly until failure. We do this with a tire installed and from multiple directions so that there are impacts on both bead hooks and on single bead hooks so that we can best simulate real world use. The improvement numbers come from the number of impacts to failure when comparing old and new rims. For alloy rims, the improvement not only comes from an improved rim profile design, but also from the fact that some of the older rims used 6066 or 6061 alloys and the new rims are using 6069 alloys. While the numbers seem dramatic on the surface, they indeed are what we found from extensive impact testing of these rims. We spent A LOT of time on the shape and profile of the new Sylvan race rim and while the old TRS Race rim was actually already pretty darn strong, the new Sylan rim puts it to shame on the impact test we use. The impact test we use is pretty violent and we'll have a video of it up on our YT channel in the near future.

Thanks for the kind words @JMslo. Those 28mm carbon rims do REALLY well in our mechanical impact testing. They certainly perform above their weight class!

Hey Danstar10 Our policy is to replace warranty product with the same item that failed. If it is an older product which is no longer available we replace with the current equivalent in our product line. That said, we are happy to work with anyone if a different model is more appropriate for their use case so we can ensure they are on the best product for your riding style/terrain. Your lifetime warranty remains unchanged.

@chacou: Thanks for the kind words. Glad the new stuff is working out for you! We've been working hard on continued improvements.
