|   Yeti AS-R: does suspension lock out under braking? | timjboston
Jan 7, 2002 8:30 AM | | I'm considering buying an AS-R. I've read conflicting statements regarding whether the rear suspension locks out under braking. MBAction wrote in its review last month that it does indeed lock out under heaving braking, causing it to chatter. However, I've also read (in the blurb accompanying the AS-R advertisement for Adrenaline bikes) that the AS-R's linkage is SPECIFICALLY designed to isolate the suspension under heavy braking, such that the shock can still move through its full range of travel. Which is correct? Yeti owners? Dealers? Other knowledgable parties? While I'm at it, how does it climb as compared with a 4 bar linkage, horst link bike? (I currently own a Tracer, which climbs anything like a champ, but I simply don't like the high bottom bracket and relatively small cockpit) |

Jan 7, 2002 7:06 PM | | The differences are very subtle in rear braking and mostly due to the type of brakes, disc vs rim, and rear tire design. After those major factors there are less perceptible differences in rear braking.
Bikes that allow (or worse even induce) fast extension will stiffen up suddenly at top out or require more than average rebound damping to stabilize and smooth out the jack (extension).
High pivoting suspensions won't allow as hard a rear brake as lower pivoting suspensions due to the difference in traction when compressing with a rearward path in relation to the bike's weight momentum vs extending with a forward path to the momentum.
Bikes requiring slower damping and stiffer springs for stability brake the rear wheel worse than stable handling bikes with softer rear springs and faster damping.
The AS-R will act like a middle height monopivot with rim or disc brakes due to it's IC focus around the main pivot with rim brakes and mono-pivot geometry with a rear disc. It will brake with much stability due to it's anti-jack geometry and feel a little bit stiffer than a Tracer under braking and pedaling and bob about the same (very little). It will require an average amount of damping for handling stability. Although it won't do anything as quite as well as a Tracer, or any other FSR licensed geometry available today.
