Is a single-ring best for cyclo-cross?

SRAM’S JP Mccarthy, road product manager and expert in CX, talks about why riding 1X off-road is the better choice over a double-ring chainset

“Most importantly SRAM 1X improves the rider experience,” says JP Mccarthy, the man who oversaw the migration of 1X tech from mtb to the cross and road market. But what is it?

The system is made up of three parts: SRAM’S X-sync singlering, chain and the clutched rear mech. “Those three components are critical. Chain retention and mud-clearing capabilities are important upfront and the rear derailleur helps manage chain motion. It has a clutch that keeps the chain from bouncing, along with guide pulleys that all help to stop chain slap and derailment.”

Simplicity “The simplicity really speaks to cyclo-cross riders, eliminating parts that might fail and parts that need to be cleaned. “In a lap you can find up to 20 different features; as long as you’ve got the range in your cassette you can go into the right gear with just one hand, not worrying about the big shift at the front that can often lead to deraillment.”

Security “We have been riding 2X and 1X sideby-side and we’ve found that the 1X has fewer chain drops than a 2X.”

Quieter “On the 1X system we have no chain slap; we really emphasise that for 1X in general because a quiet experience is a better ride experience.”
