Hi everybody, this is Doug from Corsair Bikes.
An important question was asked about chain growth. This bike has 5mm of chain growth at 180mm of travel. To put that in perspective, you'd be hard pressed to find another bike with that small amount of chain growth. Even most short travel XC rigs have much more than that.
And another point to make about how the idler pulley manages chain growth, it does so regardless of which chainring you are in. So while many bikes pedal 'differently' whether you are in the small, medium or large chainring, our idler pulley technology makes pedalling in any chainring the same.
A final note about the idler pulley technology. It is not mounted at the exact same place as the pivot. But where it is mounted creates a certain amount of 'anti-squat'. This greatly improves efficiency while pedaling and climbing.
Concerning the headset, we think our set-up is a big plus. We think there is no reason for everybike to have adjustable headtube angle. It is an aspect of the bike that is very personal. Not only steering feel, but a riders fork length/travel preference. By having adjustable headtube angle, the rider is able to tune the bike for their ideal reality while not sacrificing other important characteristics like BB height.
Finally on the headset topic, one could use a 'Zero Stack' headset in our frames, or we suppose some aftermarket guys will create some 'reducers' so that one could use a conventional 1 1/8" headset.
Check the link below. it has the full rundown on the Maelstrom.

Maelstrom frames have suffered further delays and will start to ship in September.
