Get these tires and never look back

The IRC broken double cross 42’s are the BOMB. They roll fast, handle chunk really well and are predictable in all types of terrain. The side walls are awesome with a plush ride yet. I’ve never seen a sidewall tear on any bike that I’ve seen these tires mounted on. I’ve seen lots of flats with other tires and many people not make the climb because they’ve lost traction or slide out in a turn, even though they have better bike handling skills than I do. Just like in the title of this post states get these tires and never look back.

Dee - thank you for your honest review of these tires. We really like them too!

Superior Off-Road Performance

These tires will make you fly on gravel, dirt, and sand race segments. Mucho traction so you can keep on the power. They are INCREDIBLE in the sand! As always, proper inflation is key to performance. They take a licking and keep on ticking!

Tires were excellent at the Rock Cobbler for a smooth ride and made the downhill corners stable! I greatly appreciated the tire psi recommendation from Steve that was hand written on my invoice!

Awesome shipping, Awesome tires

Really impressed with pure gravel prompt shipping. I ordered online and received my tires stem cap and orange seal within a few days. My wife and I have ridin many different gravel tires but once we found the IRC double crosses we stoped trying anything else. These tires do all conditions road chunk and gravel extremely well AND hold up and wear great. We either ride 42 on the front and 42 on the back or sometimes 42 on the front and 38 in the Back can’t go wrong with either combo.
Great job Pure Gravel and IRC.

Perfect for Bikepacking

Put these guys on and loaded down the bike for a 2 weeks trip. They have handled the weight in all conditions with no issues!
