this post deserves to be repeated. I've got 66.5 with my lyrik solo air on my cove hustler, and its a bear to handle. definitely wanders and forces an inordinate amount of attention to keep it tracking where you want. sometimes you just need to go with the flow! it's probably a bit slacker than I'd prefer, but I can manage the climbs and it makes for a fun descender. definitely wouldn't want it any slacker as it would definitely become an unruly pig at that point.At that point they would be "slopestyle/mini DH bikes" not trail bikes.
Have you climbed with anything slacker than a 65deg. head angle?
It's really not so much fun. To me, my trail bike has to be able to get me to the top in order to be able to blast the downhills in the trail. Further more, if someone is going to market a bike as a "trail" or "all-mountain" bike, people will expect it to climb well. A slack head angle on climbs is quite awkward and the wheel loves to flop. In addition not everyone wants to have to flip a lever to raise there seat and twist a knob to lower their fork everytime a hill arises(poor pun intended). Finding a happy medium, that allows me to hop on, pedal to the top and blast down without worry appeals to me. Less is more, and I want more; more fun, more time on my bike, and more stories about how much fun it is to ride a bike.
Maybe I'm the only one that doesn't want to make my trail bike into a short travel bike wishing it were downhill bike.
