Product Description

Shelter Wheel Kit is made of 35 washers that fit snugly over the valve stem, gluing at its base, with an elegant and almost invisible silencing effect.

It's also great to balance wheels, with an additional vibration-reducing action.

Key Features:
  • Eliminates valve noises, especially on high-profile rims
  • Shelter washers can be used to finely balance wheels
  • Visco-Elastic behaviour reduced vibrations

How to silence valves:
Shelter Wheel Kit is made of 35 washers that fit snugly over the valve stem, gluing at its base. With minimum bulk and weight, they provide an elegant and almost invisible silencing effect, cancelling unwanted valve movements and vibrations. The re-sealable bag makes sure washers retain their properties if needed for successive applications.
Once Shelter washers are applied on the rim, it’s possible to remove the valve an re-insert it without loosing the silencing effect. This is just one application of our Shelter Wheel Kit, but there’s more.

Nobody would drive a fast car whose wheels haven’t been carefully balanced after mounting tyres on.
Current high performance bicycle wheels, with fancy ceramic bearings, lightweight carbon rims, cannot deliver their full potential if not properly balanced.
It’s an easy task that only requires a Shelter Wheel Kit, a wheel truing stand (or a bicycle turned upside down..), patience and some minutes per wheel.

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 (that can be added later). 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.

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.
Often wheels stop with the valve at the lowest point… but sometimes uneven weight distribution on the tyre or less-than-accurate carbon fiber lay up overcompensate that, and the lowest point is not corresponding to the valve.
Keeping the lowest point of the rim/tyre as reference, identify the opposite point on the rim (you can find it using a ruler, aligned with the lowest point and the wheel axle) and adhere a Shelter washer there.
Repeat the process from #1. Each time the heaviest point may move slightly (because of friction in the hub), but it will normally remain within a +-10 cm (4 inches) range.
The wheel is balanced when, upon making it turn, IT WILL STOP WITHOUT ENTERING THE PENDULUM PHASE (it won’t change its rotation sense). With each subsequent spin, the lowest point when the wheel stops is a random point on the circumference, changing every time and depending on bearing friction.

Washers can be adhered one on top of the other, or side by side, on top of the rim or on its side (depending on rim profile/size).

A good trick, although not always possible, is finding a spoke that’s close to the lightest point of the wheel and cutting the washer on one side, so that the washer can be put around the spoke.

Each Shelter washer weights around 1 g. Typical wheel unbalance ranges from 4 to 12 grams.

Visco-elasticity reduces vibrations:
That’s an added bonus when balancing a wheel with Shelter washers.
The transmission of vibrational energy through any structure can be reduced by introducing visco-elastic materials at discrete points. It’s exactly what Shelter does, contributing to reduce vibrations on very stiff wheels.

Occasionally, without notice, manufacturers change product design and/or specifications.

Wheel & Tyre Tool Guide

 

Wheel & Tyre Tools

Essential to a smooth rolling bike is well-maintained wheels and tyres. Removing old and fitting new tyres is much easier with the correct tools. While wheel maintenance is a little more involved, it can be done at home with the correct tools. Keep your wheels and tyres running as they should with our wide range of tools.


Tyre Tools

Even the most basic toolbox or on-bike tool kit should include at least one tyre lever, though having a pair makes removal and fitting of a tyre much easier. Not all tyre levers are created equal and you might be surprised by the price of some pairs, though the investment will be worth it when compared to the annoyance and struggle of using cheap tools. The best tyre levers have become go-to workshop tools and can be part of your tool kit for use on any type of tyre for any bike. Please see our guide on how to fix a puncture for more detail on tyre lever use.

Tubeless tyres use sealant to seal any small punctures, but occasionally you will get a larger hole that the sealant cannot seal. Anyone who rides with a tubeless set-up should carry with them a tubeless repair kit just in case. Having a repair kit that is easily accessible means you can get to fixing the puncture before too much air is lost, making inflating that much quicker and easier. Most use some type of plug or dart that is pushed into the hole to seal, quickly removing the insert tool keeps the plug in place and you can keep rolling and continue your ride.

Wheel Tools

A spoke key is a simple tool that allows you to straighten your wheel if it becomes slightly bent. Part of any good tool box, the spoke key is effectively a very small spanner, the spokes of a wheel are attached to the rim using threaded nipples. In the construction of a wheel, the spokes are tensioned equally to the rim, creating a strong and "true" wheel with no side to side wobble or flat spots. Over time and impacts, some spokes can loosen, or the wheel develops a wobble, a spoke key is used to tighten or loosen the nipples to true the wheel. Most are not one size and have several different sizes to suit different size nipples.
