First Look: KHS Goes 650b for Downhill - Introducing the SixFifty 656DH 23
KHS did it. They went to 650b on their downhill bike. As far as we know, they're the first company to give it a go. The larger wheel size has a few advantages, like the ability to roll over rocks faster, but suitable downhill wheel and tire options are quite limited at the moment.
The KHS Factory Team will be testing out prototype models of the SixFifty 656DH in the next six weeks. In fact, Logan Binggeli plans to ride the 650b version at the Red Bull Rampage this year, so keep an eye out for that.
The bike is based around the current DH300 but has slightly tweaked geometry to accommodate the larger wheel size. As of right now the anticipated release date is late 2013 or early 2014.
What do you think? Is 650b fit for downhill?
