IRC Serac CX Sand 32c Tubeless
Don’t be fooled by the name, as the IRC Serac Sand tire does more than just sand well. The diamond tread tubeless cyclocross clincher is a great option if you’ve got more dirt and gravel than pavement on your big ride.
Just as with the IRC Serac and Serac Mud options, the Serac Sand is woefully undersized for the non-UCI racing adult cyclocross racer, but they were the tires of choice for the NoTubes UCI-width-restricted team as well as Amy D’s Rebecca Fahringer (paired with wide NoTubes Valor rims) in 2016/2017.
The 32c tire measures out at 32mm on a wide 20mm internal width rim, or around 31mm on a 17.5mm rim. Without side knobs, the narrow width might fit on a long-reach road bike with a narrower rim, and offers plenty of room for mud or fenders on a normal cyclocross bike. We’ve heard a 40mm version is coming, but haven’t seen it yet.
The tubeless bead and casing make up for the lower volume, and without the worry of a pinch flat, you can go low and absorb the bumps or pavé. The Serac CX Sand provides a tight, reliable fit on most rims but doesn’t require as much effort to mount and seat as the WTB Exposure.
Bonus: Leave them on all summer and be ready for early season sandy cyclocross races, and keep them around for ice and snow.
At 376 grams, it’s not light for its size, but offers fast-rolling tubeless performance to get you to the velodrome or pub on time.
