- For installation of 700c clincher or tubeless specific tyres that comply with European Tyre & Rim Technical Organisation standards.
- Do not exceed the maximum tyre pressure as stated on the interior of the rim!
Basic precautions > riding
Riding a bicycle always involves potential danger to both the rider and others around. Even with the proper use of approved safety devices and equipment, accidents resulting in injury or death can occur. Acknowledge these risks and be conscious of these risks and ride within the ability of yourself and those around you. Do not overestimate your technical ability!
Risk of accident through damaged wheels
Avoid riding through potholes, over curbs, steps, rough edges or compromised road surfaces. • Check your wheels regularly for damage — particularly the outer perimeter of the rim which is most susceptible to impact damage. This is especially important after a big impact or a tyre blow-out. If any dents, cracks, large areas of abrasion or other abnormalities are present, then contact us direct at: email@example.com to arrange an inspection. • Lightly pluck each spoke to check tone. Each spoke should ping (not rattle) but will only vary significantly in tone from left-to-right of the wheel. Please note; front and rear wheels will also sound subtly different. • Never ride damaged wheels. • Do not continue to use your bike after a serious crash, before getting the whole bike inspected by a reputable bike mechanic.
Basic precautions > care
Be aware of your own technical ability. The hubs are the only serviceable part(s) outside of the factory, but even here, good technical competence and prior experience is essential. Be aware of maximums and minimums. • Tyre pressure: 6.2bar/90psi (Maximum) • Tyre size: 25-32mm Clean and inspect wheels regularly. Clean with only light detergents. For more stubborn residues such as tar, the frugal use of isopropyl alcohol is permitted, but contact of isopropyl alcohol, on the decals should be avoided. Never use a pressure washer or steam system to clean your wheels. Use light dedicated bicycle cleaning detergents only. Ensure the disc brake rotors are not contaminated during any cleaning. If in doubt, source a dedicated disc brake cleaning product from your local bike store.
Storage and transport
Your wheels are designed to be exceptionally strong in-service for as-intended use. However, they are still vulnerable to abuse and improper storage. The sidewalls of the rim are of highly-ordered carbon fibre, but very thin (~0.2mm at its thinnest) and supported by a structural foam material. Although most effective for its intended application, is susceptible to point loads and contact damage. When transporting or storing your bike/wheels, ensure suitable padding is used to provide a soft interface and an even distribution of load. Do not store your wheels with ambient temperatures above 60OC

On the road
Never ride on a flat tyre and stop as soon as possible if a blow out occurs
Never ride with damaged wheels, or wheels that have been subject to a significant impact. If such instances occur, send your wheels to Partington for inspection, even if there is no visible damage. Arrangements can be made via firstname.lastname@example.org. Avoid riding over potholes, curbs, steps or unduly rough terrain.
