We got a good look at Helen Wyman’s new Kona cyclocross bike today at Gloucester, and we also had a few minutes to chat with her about the first use of the new Chicane tires from Challenge that she and her husband helped design.

Wyman’s bike, a Super Jake CX, is Kona’s carbon foray into disc brakes, and it’s not just disc mounts on the old carbon frame that Wyman and Barry Wicks raced last season. Wyman explained, “First of all, to make it disc brake compatible, they’ve taken the entire frame and redesigned the rear triangle and it’s incredibly stiff.” The European Champion gushed, “It’s incredibly light, it’s lighter than last year’s bike.” We last looked at an iteration of Wyman’s ride back in 2010 when she was on the Kona Major Jake.

For componentry, the most interesting part is the exclusive Easton wheels, using Easton’s new wider EC90 SLX rims mated to Easton’s M1 mountain bike disc brake hubs.  “The wheels are Easton but they’re specially made for us and the Rapha team, with a road rim and mountain hub,” Wyman points out.

She added, “It has the new tires from Challenge on it, the Chicane, which will be out soon.” It was interesting to observe that Wyman’s tires are not Challenge’s Team Edition cotton versions, at least not yet.

Wyman remains on 10-speed components, and instead of SRAM’s new Red hydraulic disc brake, she’s using TRP’s mechanical Spyre system. Of her new mechanical disc brakes, Wyman had nothing but praise: “I really like disc [brakes]. It’s like you’re on cantis, but you stop. For the first time ever, you actually stop.”

@bkappius "We" apparently does not include the companies still supplying these for 'cross. If they do know, then it's negligence.


@KingOfTheApples Why/how does it happen with HY-RD? Thought that was the problem the hydro caliper solved?


@jverheul bummer about being sponsored and told what to ride. Although trp makes a mechanical to hydro one. Mech are great, if it's dry


@jverheul I thought same, but helped a guy at who’s brakes failed. Readjustment fixed problem. They did not self center/compensate.
