The benefits of gravel wheels G25

For riders on rugged and loose terrain, mainly riding on dirt, it is important to usually find more confidence and control from larger-capacity tires.
G25 can be applied to wider tires, allowing you to face various situations with ease in bikepacking.
G25 gravel wheels get rid of the shackles of road wheels, allowing you to get a riding experience no less than MTB ride.

Gravel biking is sweeping the world, and ICAN has been part of the revolution since it began. The company keeps up with new technology and  research findings to produce cutting edge, affordable carbon frames and bike components for gravel riding. And now ICAN engineers have come up with a new 650B carbon wheelset – a handbuilt landmark in wheel design, launched in 2021.

Meet the new 650b gravel wheelset G25. It has everything a gravel rider or backpacker needs in the 650B size.

At 27.5” diameter, performance strikes a happy medium between 26” and 29” wheels. Fatter tires and lower pressures guarantee a stable, comfortable ride, somewhere between the sharp responses of a 26” MTB wheel and the smoothness of a 29er. And it's popular among shorter riders, who find a 29” wheel is too tall for them.

carbon 650b gravel wheels

The entire wheelset mass is only 1340 grams. With an internal width of  25mm, the carbon rims can take tires measuring between 35mm and 50mm.

They give what enthusiasts call “a real MTB” feel” on a rough or unstable surface. And they are ready to go tubeless. The lay up is in Toray T700 fiber, for a rim that's 35mm deep. Black alloy spoke nipples match the rim color, and the 24 tough spokes are Sapim CX-Ray, laced in two-cross pattern.

The disc brake hubs are the new ICAN D21 – thru-axle centerlock,12x100mm in front,12x42mm rear, and ready for disc brakes. The rear freehub is a marvel in itself, with six pawls, and no less than 72 attachment points. Freewheel, and listen to that sweet buzz! It's ready to take a Shimano 10 or 11 speed cassette – or a Sram XDR.

As off-road cycling spreads out into various branches, ICAN engineers are ready to meet difference  performance demands.

And the carbon gravel wheelset G25 is just such a no-compromise design, with a single purpose – to give the gravel rider and backpacker an optimal experience. It sells for $650 and comes with a two-year guarantee.

What is the best tire size for my ICAN wheels?

The best tire size for your wheel, which depends on the wheelsets type, size and the conditions you plan to ride the wheel in.
If you focus on speed,aerodynamic, each carbon wheel will have a specific recomended tire width, which is listed on specific product pages under rim specs.

We find(Not necessarily 100% correct):

  • With a broader external width, ICAN Cycling wheels roll most optimally with a 25mm/28mm (actual width) tire.
  • For Jet wheels, we recommend 25mm (actual width) tires, but 28mm (actual width) tires are still an excellent choice.
  • Unless a podium step hangs in the balance, the difference in the speed of the Jet, using a 25mm tire versus a 28mm tire, works out to only 0.05 kph. That’s approximately 3 – 4 seconds over 40km.

What is the recommended tire pressure

If you want the right tire pressure,please read the guide for recommended tire pressure.

The prices of the same products in different warehouses are different. We have prepaid taxes and freight for users who purchase products in overseas warehouses.

The reason may be that the spokes tension of wheels is too high. Please check that the spokes tension to make it at a the proper range.

When riding for the first time, freehub needs to run in with the wheels. Just ride for a while, freehub will run well.
