FAQs

Please read our FAQs page to find out more.

What size tires can I use on my G3 gravel rims?

Cenos gravel rims are wider than some of the competitors MTB rims. So there is no strict limit on tires. Though we do recommend using 30-50mm tires. Remember to keep up with the pressure requirements. If you run a road tire on them, make sure it is hookless compatible.

What is the system weight limit for you wheelsets?

We design our rims with durability and longevity in mind. The weight limit on road wheelsets is 120kg and 100kg on gravel and MTB wheelsets.

I have crashed and destroyed the wheel, can you help?

We have a crash replacement policy, you can find it here. Contact us and we will help you get back to riding asap.

Do you sell front and rear wheels separately?

Sure, we can sell the front or rear wheels separately. Please contact us by email and we will arrange it.

How much tubeless sealant should I use, and how often it need to be refilled?

The amount of sealant required depends on the width of the tire. The sealant should coat the inside of the tire walls and there should be a small puddle in the bottom. Use these values as a base, but more sealant would always give more protection.

  • 25mm tires – 40-50ml
  • 28mm tires – 45-55ml
  • 32mm tires – 55-65ml
  • 40mm tires – 70-90ml
  • 45mm tires – 80-100ml
  • 2.1” tires – 100-120ml
  • 2.25”+ tires – 120+ml

The sealant is water-based and dries out over time. Do not leave the tires in the direct sunlight as this accelerates the drying. Refill the sealant every 3-4 months.

Can I use metal levers to mount the tires?

Absolutely not. Our rims are designed for an easy tire mount. While mounting, make sure that the bead of the tire sits in the center lower part of the rims, and you should be able to do it without any tools at all. 

Why does Cenos offer ceramic bearing option?

Generally speaking, ceramic bearings are not suited for cycling. In industrial or medical equipment applications, where the rpm is high, the load is low and the operating conditions are clean, ceramic bearings perform well. However, that is not the case in cycling, where bearings are highly exposed to high loads and the ingress of water and dirt. The optimal ideal rating of ceramic bearings is 10.000rpm+. In cycling hubs applications, the maximum rpm may be up to 500-600rpm, (road wheel at 35km/h is 265rpm). In these conditions, the advantage of ceramic bearings is negligible and does not provide a performance benefit for cycling as many people and companies claim they do.

Another issue is the hardness of ceramic balls. The shocks of hitting potholes and other road bumps impact the hard ceramic balls into softer steel races, which eventually get dented and lose their smoothness. This causes drag and short service life.
