The 650b or 27.5er gravel wheels offer most of the quick acceleration and nimble feel of 26in mountain bike wheels, but with a nod towards the smoother feel, extra stability and enhanced traction of 29in wheels. They’re also more suitable for smaller riders than 29ers.

For gravel riders, the higher volume tyres associated with 650b rims allow for lower air pressures.G25 will be your good choice.

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.

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.

What hub does the 650B gravel wheelset G25 use?

The 650b gravel wheelset is equipped with ICAN Cycling's latest 6 Pawls Freehub with 72 Engagement Points.See the video below.
