Patented 6-bar suspension technology. Independent control of dCSL and shock rate.
Engineered by Level One Engineering
01 / Technology
In conventional 4-bar and single-pivot designs, chainstay lengthening rate (dCSL) and shock rate are kinematically coupled — optimizing one inevitably distorts the other. Every suspension design becomes a set of compromises. The L6 system breaks this constraint.
By adding two links and three pivot points beyond a conventional 4-bar layout, the L6 architecture introduces additional kinematic degrees of freedom. A defining feature is the three-pivot chainstay link, which provides direct control over the chainstay's motion through travel. The result: dCSL and shock rate can be shaped independently, enabling suspensions that are precisely optimized for their intended platform.
01
dCSL and shock rate are decoupled, giving engineers freedom to optimize pedaling dynamics and shock performance independently.
02
The shock rate curve shape — rising rate, linearity, progression — can be designed exactly as intended without distorting chainstay behavior. No other linkage type offers this.
03
Anti-squat and anti-rise characteristics can be tuned separately from shock rate and dCSL. Pedaling efficiency is a design choice, not a side effect of other compromises.
04
From short-travel trail bikes to long-travel enduro platforms and e-MTBs, the L6 system scales across travel ranges and riding disciplines.
