Really Bike Rumor? “Cannondale Breaks Down…” You couldn’t have worded that any other way?

The bike looks awesome though. Well done.

What, no thru Axel? Just kidding! I think it’s awesome. And for quick wheel changes in race situations it’s mint if the stiffness numbers are true.

29er, short stays, agility, and an asym rear triangle for better der clearance and even spoke tensions?

Sound like Bystickel circa 2006.

regarding the chainring moved out to the outside : will that not result in supporting only a crankset with a rather large q factor ?
in other words something around 170mm ?

well done on the mud clearance and general design !

many mountain cranks have plenty of room to move the rings to the right before they interfere with the arms. but likely it’s all a non-issue anyway when using their crank w special spider.

Why does everyone keep banging on about thru axles? Is torsional stiffness in the rear wheel of an XC bike that affected?

Did anyone watch guys try to change thru axle wheels at Nove Moste? It was excruciatingly slow and awkward.

I own a 2006 Cannondale prophet and I have to release the front caliper in order to release the front wheel from the lefty ?

Unless it is different with newer lefties (feel free to correct me) it looks to me that wheel change is a dubious reason to keep quick releases at the rear.

How does increased fork offset and slacker headangle offer a quicker steering? I would have thought it did just the oposite.

I wonder if, with the geometry changes, if the fits will be the same–that is, if a person rides a large now will the new large be the same fit?
