The suspension stem freeQENCE absorbs up to 75% of all vibrations and impacts and therefore reduces your fatigue. You are riding more comfortable, faster and safer on paved roads, cobblestones, gravel roads, singletrails and technical terrain. The significant relief of your wrists may also avoid tingling and numb hands.
The torsionally stiff and ultra compact parallelogram construction guarantees optimal absorption of vertical impacts. In contrast to single pivot suspension stems, the handle bar does not tilt down. In contrast to supension forks, the frame geometry remains unchanged. The freeQENCE parallelogram enables an internal spring linkage.
In contrast to single pivot supsenion stems, the lever length does not influence the spring characteristics - due to the elaborate and complex parallelogram kinematics. No matter if you use your handebars hoods, drop or top position - suspension and damping performance always remain optimal.
The brandew suspension stem Vecnum freeQENCE
is the winner of the Design & Innovation Award 2022.
Four unobtrusive but perfectly tuned high-tech elastomers protect you from harsh impacts and vibrations. The maximum suspension travel of 30mm is split into 20mm positive travel and 10mm negative travel - similar to the sag of a supension fork. The supension stem freeQENCE has a homogeneous, linear spring characteristic with srong progression towards the end of stroke.
The suspension stem freeQENCE offers you an external and steples adjustment to your weight and inteded riding style. The patented internal spring linkage makes setting up your desired spring characteristics easier than on any suspension fork.
The freeQENCE design is consequently optimized for high loads and low weight - starting with 287 grams at 90mm length. That is only about 150 grams additional weight compared to a standard stem. Without the disadvantages of a supension fork, your bike does not suffer ftom aerodynamic losses, it remains light and agile when sprinting and riding out of the saddle. The bike geometry remains unchanged. You do not need a lockout for your freeQENCE stem.
The suspension stem freeQENCE is simply mounted like a standard a-head stem. Upgrading is easy and done in a few minutes. Thanks to the open face 4-screw clamping, nothing needs to be dismounted from your handlebars.
Available in 3 lengths - 90 mm, 105 mm, 120 mm.
For 1⅛ inch forks and all handlebar types with 31,8 mm diameter including carbon handlebars. Please note the required shaft length of your fork.
At Vecnum, development, CNC processing, assembly and field testing is all single source and under one roof. As usual we focus on highest quality: all structural freeQENCE parts are machined from solid AL7075, the stem is equipped with titanium axles and screws, etc.
The suspension stem freeQENCE was tested externally by the independant EFBE laboratory according to their test standards for gravel stems and handlebars.
