What is anti-rise in simple terms?

It's how much the design prevents the bike's rear end from rising (extending) when you brake with the rear brake. It's the cousin of anti-squat, but for braking instead of pedaling.

Is high or low anti-rise better?

It depends on the use. High keeps the geometry planted and stable under hard braking, but the suspension becomes less sensitive right when you're hitting bumps while braking. Low leaves the suspension more active and with more traction, but the rear moves more. It's a balance.

What is anti-rise (the rear end under braking)

Quick answer

Anti-rise is the cousin of anti-squat, but for braking. When you squeeze the rear brake, your weight shifts forward and the rear tends to rise (extend). Anti-rise measures how much the design counteracts that. High = the bike stays planted and stable, but the suspension becomes less sensitive under braking; low = more active and with more traction, but the geometry moves more. It's part of suspension kinematics.

If your bike feels "weird" or stiffens up right when you brake on a bumpy descent, it's no coincidence. It's anti-rise doing its job — for better or worse depending on the design.

Have you felt how, braking hard downhill, one bike "digs in" firm and another seems to lift its tail? That difference is anti-rise.

When you brake with the rear brake, your mass transfers forward (like when you brake in a car and lurch toward the windshield). That transfer tends to extend the rear suspension. Anti-rise is how much the design resists that extension.

Anti-rise: braking at the rear sends weight forward and the rear tends to rise; anti-rise keeps it planted — Anti-rise = how much the rear resists "lifting its tail" under braking.

High vs low: the balance

High anti-rise (near 100%): the geometry stays stable under braking, the bike feels planted and predictable — but the suspension "stiffens up" a bit and tracks bumps worse while you brake. Low anti-rise: the suspension stays very active while braking (more grip in the rough), but the rear rises and the geometry moves more.

Neither high nor low is "better": a DH design seeks stability (tends toward more anti-rise), a trail design wants the wheel to keep tracking the terrain under braking (usually runs lower). It's a decision of character.

What it depends on

Unlike leverage ratio, anti-rise doesn't depend on the spring or the shock: it comes purely from the geometry — where the pivots are and where the brake force line passes. That's why it's a fixed property of the frame that you can't change with adjustments; it comes decided from the factory.

Common mistake: confusing the stiffening from anti-rise with a suspension problem and starting to drop pressure or open up compression. If the rear only "binds up" while braking hard and runs fine otherwise, it's design anti-rise, not a fault: no shock adjustment removes it.

Frequently asked questions

What is it in plain terms?

How much the design prevents the rear from rising when you brake with the rear brake. The anti-squat of braking.

Is high or low better?

It depends: high = stable but less sensitive while braking; low = active and with traction but the rear moves more. A balance.
