Valve silencing and wheel balancing kits Effetto Mariposa Shelter

Valve silencing and wheel balancing kits Effetto Mariposa Shelter

Shelter Wheel Kit consists of 35 adhesive washers: slipped onto the valve, they stick to the rim and prevent vibrations or annoying noises in an elegant and almost invisible way.
The Kit is also ideal for balancing the wheels, with the added effect of reducing the vibrations of the visco-elastic material.

STRENGTHS:

• eliminates annoying noises in the valve area, especially on high profile rims


• Shelter washers can be used to balance the wheels


• the visco-elastic behavior of the material reduces the propagation of vibrations

CHARACTERISTICS:

How to make valves silent:

Shelter Wheel Kit consists of 35 adhesive washers: slipped onto the valve, they stick to the rim and prevent vibrations or annoying noises in an elegant and almost invisible way.
The resealable bag ensures that unused washers retain their characteristics even for subsequent applications. Once the Shelter washers are glued onto the rim, the valve can be removed and reinserted, without losing the precious "silence". This is the simplest feature of the Shelter Wheel Kit, but there's so much more.
No one would drive a sports car whose wheels were not carefully balanced once the tires were installed. In the cycling sector, current high-performance wheels perhaps equipped with ceramic bearings and very light carbon rims cannot reveal their full potential without having been correctly balanced. It's a simple operation that requires a Shelter Wheel Kit, a wheel stand (bench... or an upside down bicycle), a little patience and a few minutes of time

How to balance the wheels:

1. Fit the tire and any brake disc so that the wheel is ready for use. Place the wheel on a support where it can rotate freely.


2. Turn the wheel with a light push. After a few complete revolutions in the direction of thrust and a few partial adjustments, the wheel will stop. The lowest point of the wheel is where the excess weight is located .
   Normally the wheels stop with the valve at the lowest point... but sometimes an uneven distribution of weight on the tire prevails, so the heaviest point may be elsewhere.


3. Mark the lowest point of the wheel with a pencil or a piece of tape. We will call it point “A”.


4. The diametrically opposite point on the circle, point “B” is where we will glue a Shelter washer. This is to counterbalance the excess weight at point “A”.


5. Repeat the process from step .2, putting the wheel back into rotation. Each time the heaviest point "A" will remain approximately the same (with a tolerance in the position of +-10 cm) and each time we will proceed to glue a Shelter washer at point "B".

When point “A” moves more than 20 cm from the previous position, it means that the wheel is balanced. By spinning the wheel, point “A” will become a random position, influenced by bearing friction rather than true excessive weight accumulation.

Shelter washers can be glued on top of each other, or next to each other, on top of the rim or on the sides (depending on the size / profile of the rim).

An elegant trick, although not always possible, is to find a spoke near point “B” and glue the washer around the nipple, after cutting it on one side with scissors.

Each washer weighs approximately 1 g. Wheel imbalance can require 4 to 12 grams of counterweight.

Visco-elasticity reduces vibrations:

The transmission of vibrational energy through any structure can be reduced by adding visco-elastic elements at certain points. That's exactly what Shelter does, not only protecting rigid carbon frames from impacts but reducing vibrations at the same time.
