Effetto Mariposa Shelter Wheel Kit

Balance Your Wheels For Better Performance
Nobody would drive a fast car whose wheels haven’t been carefully balanced after mounting tyres on so why do it on a bike? Current high-performance bicycle wheels with fancy ceramic bearings and lightweight carbon rims cannot deliver their full potential if not properly balanced before you ride. Why suffer poor performance when an easy task can be carried out which only requires an Effetto Mariposa Shelter Wheel Kit, a wheel truing stand (or a bicycle turned upside down), and a little patience.

Valve Silencer
The Effetto Mariposa Shelter Wheel Kit is a great way to balance wheels and to enjoy additional vibration-reducing action to sweeten the deal. It's also a super-efficient Valve Silencer. The kit features 35 washers that fit snugly over the valve stem, gluing at its base, with an elegant and almost invisible silencing effect. Once Shelter washers are applied on the rim, you can still remove the valve and re-insert it without losing the silencing effect.

HOW TO BALANCE WHEELS
Mount the tyre (and eventually disk) on the wheel, so that the wheel is in its rideable form. IMPORTANT: If balancing a tubeless wheel, make sure there’s very little or no liquid sealant inside (you can add that later). This is because liquid sealant spreads while riding without creating wheel unbalance, but it will interfere with static balancing.

Place the wheel on a truing stand and make sure it can rotate freely. Then with a gentle push, make the wheel spin. After a few complete rotations in the direction of the push, the wheel will enter a pendulum phase where it makes partial rotations, back and forth. Behaving like a pendulum, the excess of weight on the wheel is subject to a restoring force (due to gravity) that accelerates it toward the equilibrium position. Amplitude of swings will reduce until the wheel stops: the lowest point is where the excess weight is.
