Dry or wet, soft or hard pack, the Assegai is a true grip monster yet still rolls well thanks to it's closely spaced and ramped tread. Tall should tread provides corner ripping grip in all conditions and the Assegai is incredibly under braking too, providing all the traction you'll ever need.

The IRC Formula Pro RBCC Tubeless Road Tyre is race tyre with the emphasis on wet grip and durability. This tyre is the ultimate all round race tyre. Offers superb grip in wet conditionsHighly durable tyre with a high TPI casingRace proven tyres fully tested in the UKOffers a superb ride and low rolling resistanceMore tread cover on the tyre improves grip in cornersThere are lower rolling resistance tyres, but they tend to puncture more easily and don't have the same grip across a range of conditions. The rice bran ceramic compound (RBCC) has been revised to improve grip in wet conditions. IRC claim a 4% improvement and a 10% drop in rolling resistance. These are race tyres and have been race proven in the U.K throughout 2017/18. After a season racing by Team on Form the tyres and a Belgian team are not even close to worn and have helped the riders clock up wins. The tread rubber now covers more of the tyre so you can lean even further into a bend than you probably should. The natural latex lining is retained to improve comfort and reduce rolling resistance. The High TPI casing means the ride on these tyres is sublime. Rough roads are taken in their stride. The new tyres measure 25mm and 28mm on wide rims! Unlike most brands IRC know wide rims offer the best performance and a 28mm tyre that sits like a 31mm tyre is not going to fit in many bikes. The tyres also do not sit tall and this is useful for those running mudguards.
The original full-performance version. CushCore Pro allows you to push the limits of your tyres and suspension to new levels. The best choice for most wheels, terrain and riders.Tyre Widths - 2.1"-2.6"Inner Rim Width - 22mm-35mmWeight - 250g (27.5") / 260g (29")Includes 2 x CushCore tyre inserts, 2 x 44mm CushCore Presta air valves, valve core tool, installation instructions and rim stickers.Not all tyre inserts are created the same. CushCore is no ordinary tyre insert and is based on a new concept, tyre suspension. Any suspension system has a spring and a damper, and with CushCore, pressurised air in the tyre is the spring and the CushCore tyre insert is the damper.Like traditional suspension, a constant damping force wouldn't work. It must be dynamic. Suspension should be supple on small bumps but firm on the big hits.CushCore responds differently depending on the tyre load and scenario. The more the tyre flexes, the more damping it provides.Go Bigger - CushCore improves suspension performance by 16% and reduces impact force from big hits by 50%. Send it with total confidence.Corner Harder - 35% more sidewall stability eliminates tyre squirm and burping, even at low tyre pressure. Rail corners with total confidence.Ride Faster - CushCore provides a 12% smoother ride and 3% reduced rolling resistance. Ride with more control, more momentum, and less fatigue. It's like taking fewer punches in a fight.
