Processing Time

Rims that are in stock can typically be built into wheels and shipped in a week or less. We try our best to keep our Hyperlight, RCX 40/45/50, and GCX 40/45/50 rims in stock as they are our most popular options.

Wheels whose rims that are not in stock will require 10-15 business days (Monday-Friday) for processing before being shipped.

Orders placed from Monday-Friday will begin processed the same day. Any orders placed on Saturday or Sunday will start processing on Monday.

Shipping Time

Once your order has been shipped, we will send you the tracking number by email. Shipping times vary based on where you live, the chosen shipping method, time required in customs, etc. Understand that in some circumstances, shipping time may be outside of the range we provided. If you require faster shipping, please contact us. 

Shipping time varies by region, with orders arriving within 3-10 business days in East and Southeast Asia, 10-15 business days in Europe, and 5-10 business days in the US, Canada, Australia, and New Zealand.

Tracking Your Order

Once your order is shipped, we will send you a tracking number. You are welcome to track the shipping status using this link: https://www.17track.net/

*For orders shipped to Europe, tracking status typically will not change until 2-3 weeks after the order has been shipped. The tracking status only changes after the shipment has already passed through customs in Europe, at which point, will take only a few days to arrive.

Returns and Refunds

At Particle, we have a comprehensive return and refund policy. More information can be found at this link.

What is included in the box?

Wheels come with two spare spokes, tubeless valves, pre-installed rim tape, and re-usable minimalistic wheel bags.

What does the system weight limit include?

The rider weight limit includes the total weight of the rider, bike, gear, and any other accessories. Exceeding this weight will void the warranty. We offer wheelsets with different weight limits. Each wheelset weight limit is written in the product description. Ultralight and light series wheels have weight limits of 100kg and 120kg respectively, while team series wheels have 140kg weight limits.

What tire pressures can I run?

We recommend you follow the tire pressures found here. While our road and gravel rims have been tested to 150psi, you should never exceed the tire pressure written on the side of your tire. Doing so will void your wheelset’s warranty.

How strong are your carbon spokes? Are they easy to replace?

The replaceable carbon spokes we use have significantly higher tensile strength than steel spokes. They are suitable for both road and gravel riding, and are mechanically secured, preventing them from dislodging. Just like steel spokes, it is possible for them to break if struck with a high force, such as from a collision. As far as replacement, they are as easy to replace as regular steel spokes.

How strong are your carbon rims?

Our of our carbon road and gravel wheels have all been designed to be more than twice as strong as the UCI Vertical Impact Test standard, which is required for professional racing. You can be confident in their durability.

Are carbon spokes under warranty?

Yes. Carbon spokes are under warranty.

If I order from the US, will I get taxed?

No. There are no additional taxes or custom duties with our free shipping option.

What does UCI approval mean? Are the wheels UCI approved?

Wheels that are UCI approved can be raced in UCI sanctioned races. All of our wheels have passed more than double the UCI Vertical Impact Test. Currently, seven of our GCX Ultralight and RCX Ultralight wheels have received UCI Approval. The remaining GCX Ultralight and Hyperlight, and RCX Ultralight and Hyperlight wheels as well as a few RCX Team wheelsets should receive their certifications at the end in late February or early March.

Why does each rim have a hole in the side?

Each of our rims comes with a drain hole, which is designed to evacuate water using centrifugal force while riding. They reduce the amount of water that can accumulate inside the rim when riding in wet conditions. These drain holes do not affect the structural integrity or balance of the wheels.

Do our wheelsets come with thru-axles?

While quick releases are standardized, thru axles come in many standards. For this reason, we do not provide them. Typically, frame brands should provide thru-axles with their frames. If you need one, we recommend you contact them.

Do I need a spacer for my cassette?

If you are using a Shimano 9/10-speed cassette, you will need a 1.85mm spacer. SRAM XD MTB cassettes also require spacers when paired with SRAM XDR freehubs.

Where can I get a replacement freehub?

You can purchase freehubs directly from us. Please do not use other freehubs on your hub due to potential compatibility issues.

Where can I get replacement bearings?

Bearings can be purchased directly through us. We strongly recommend that if you want to replace your bearings that you do so with the help of a professional mechanic. We advise against replacing freehub bearings. Instead we recommend you replace the entire freehub.

Is there a 6-bolt disc brake option?

Yes. We offer a converter for those wanting to use 6-bolt rather than centerlock.
