Ich habe mal nach der Berechtigung des Custom Link von Cascade Components gefragt, wo doch das SC MT schon progressiv ist. Hier die Antwort:
Santa Cruz doesn't really publish any material about leverage curves so where the notion that the Megatower is very progressive has come from I don't know. It's definitely progressive, but in a way that's fairly similar to the Nomad. For reference the V10, which feels awesome descending is has a similar leverage curve to what our Nomad link creates. A lot of people and reviewers alike seem to have attributed the Megatower's sometimes harsh feel to the leverage curve when in fact it's related to the tune Rockshox uses for this bike. The compression damping is too firm. I was talking to Steve at Vorsprung and he said that the Megatower is actually the only bike he's made the tune softer than the stock tune.
Now for what our link will have to offer and why it should exist. The Megatower link's two main purposes are travel options and suspension feel. The stock link isn't designed for longer stroke shocks and actually hits the frame with a 230 x 65 shock installed. Our link is designed to work with 230 x 57.5, 60, and 65. These equate to travel options of 166, 170, and 180 mm. With the stock shock and it's slightly harsh damping tune running 170 or 180 mm of travel allows it to be sprung slightly softer which offsets the stiffer damping enough to make it feel better. Running a non-RS shock the added progression is easy to deal with and it feels quite good at any of the travel options. For those who like RS products sourcing a shock like the Nomad shock, which has a slightly softer damping tune, is a good way to achieve a better damping feel. The increased progressivity actually helps maintain small bump sensitivity while having enough bottom out resistance for more aggressive riding. As for why we would want more travel, a lot of the riding up here in the PNW is quite well suited to bikes with more travel. Some trails are even DH bike worthy. The catch is you have to pedal to them. We designed the Megatower link to not affect its pedaling while giving it near DH bike descending capabilities. Because it's more progressive mid-stroke support is increased which prevents it from feeling like it's wallowing in it's travel if it's set up with a longer shock.
Long story short it opens up options that can make the Megatower an even better descender and gives riders the ability to tune the travel to what suits them best.
