If KHE would offer their bikes without that headset it would be a different story, but those headsets completely kill the entire deal. I have spoken with more than a dozen riders who have owned KHE bikes and every single one (every one!) has had issues with the headset and for those who have run rear brakes the detangler is nothing but a nightmare to work on with brake cables breaking frequently and taking far to long to change.

Are you going to walk into a bike shop and say "I need a 2.5" headset please." and actually expect a response other than "Huh?".

The Signal gives people chrome plated rims which provide superior braking.
A basic DK freecoaster which I haven't heard major complaints about.
Straightforward decent frame geometry and design - no crazy non-standard stuff
Good aluminum pegs x 4
Nice tight small gearing

Really, it is an overall design winner for the entry level rider and since the frame is steel you can just go ride some light street with no problem - just avoid grinds with those aluminum pegs (get cheap steel ones if you want).

Heck, I ride some light street on my Ares Choise frame which is aluminum with no problems. Did on my Show too... before it cracked in 5 places in one day.

KHE just doesn't give you the same stuff that DK does, with chrome plated rims being the single biggest thing. Look at almost any pro rider out there who is running brakes... chrome rims are an absolute requirement. In flatland even moreso.

The better items (perhaps) on the KHE would be the stem and bars.

The better parts on the Signal: Frame and rims

Much easier to upgrade stem and bars than get a new frame and new wheelset.
