Hi, this is Doug from Corsair Bikes. I would like to comment on the discussion of pedal feedback as it has to do with our DH race bike, the Crown. First the facts, this bike has 11mm of chaingrowth at 170mm of travel and 26mm of chaingrowth at 240mm of travel. Compare those numbers to any other bikes with these travels. And also consider that the Crown is offering rearward axle path. Not vertical or vertical to forward axlepath.
Next consider the two benefits of our idler pulley technology; First, to reduce chain growth/chainpull and second, the positioning of the idler pulley creates downforce on the swingarm while pedaling. One of the key benefits the Crown offers is the fact it is a very efficient pedalling bike. For racing, this is critical for improved acceleration and pedaling efficiency.
Next, when considering the function of a DH bike, it is important to understand you only do three things on a bike like this and that is pedal, coast and brake. Certainly you don't push down on the saddle. And certainly it is easy to understand the benefits of improved pedaling efficiency outweigh any 'firming' of the swingarm 'during pedaling'.
Finally, we will be doing a couple of very interesting videos in the next month or so to show, in a very visual manner how the Crown reacts under pedaling, coasting and braking forces.
Had a great time up in Edmonton and Calgary and can't wait to come back this summer. Stay warm and check out our new FaceBook page. 'Corsair Bikes North America'

Does the pedal feedback we witnessed on the showroom floor not translate to feedback on the trail/sore ankles? Is that negated by the axle's path?

true enough. My mechanic friend compressed the rear end of this DH rig 5 quick cycles (by hand, pushing the saddle) and the cranks backed up a full 90degs.
I was far more impressed with the slopestyle/play bike.

I'm actually considering saving up for one of those (a konig), they look like a really fun bike.

I took it for a rip around the neighbourhood when doug stuart was here in November and it was fun. Balanced, light and tight.

gnarly spring right there. I love corsair bikes, gotta wonder about the pedal feedback though.
