IRC Boken Doublecross 42

Cyclocross + Gravel = DoubleCross

As its name implies, the Boken DoubleCross is a dual-sport tire. It is a CX race tire and an aggressive all-conditions gravel tire.

Our engineers optimized the tread pattern for each size. The 33mm gives you that bite you need in high-torque CX racing and tight cornering. The 38mm and 42mm have a fast-rolling center tread for gravel and adventure riding paired with burly side knobs that hook up when the gnar gets gnarly.

With more bite than our file-tread Boken, the Boken DoubleCross gives you superior performance on loose, rough, or loamy terrain.

Love the BOKEN Double Cross

I put a pair of the 42 mm tires on my gravel bike a year and a half ago and I have ridden this bike in many different parts of the country and the tires perform great everywhere. I live in Arizona and I ride rocky, nasty single track in Phoenix, and I can ride it on the pavement too. The tires have been phenomenal. Pure Gravel is the place to get your tires.

Get them.....

I have ridden my Doublecross tires in Africa, Kansas, Arkansas and Arizona. Every gravel surface is different but these tires gripped in the corners, were fast on the flats and left me feeling secure at all times. I beat the hell out of them and they kept coming back for more.


The best gravel tire.

Get 'em

Been riding and switching between the Bokens and Doublecrosses for while now (even riding one of each at times for certain conditions) and have decided that the Doublecrosses are my new go-to tire. It's amazing in every condition. Worth every penny!

These tires Rip!

Everyone knows IRC makes the best gravel tires. What is incredible is how much they have improved/enhanced an already excellent line up. The Double Cross 42's I am running seriously hook up in the dirt. I am riding tough sections noticeably faster than before. To add to the stoke, they still roll super fast on the pavement. Lastly, I have been testing out lower air pressure with these tires (recommended). After choosing a bad line…. or two, I have smacked my rims a few times, and these tires remain unscathed! I highly recommend this tire!
