When California-Giant disbanded at the end of the 2015 season, Tobin Ortenblad was without a team and without a bike. As a Santa Cruz native, a partnership with Santa Cruz Bicycles, which recently re-released the Stigmata, only made sense for both.
Cyclocross Magazine first profiled Ortenblad’s Stigmata last year at the Sea Otter Classic, and we caught up with him and his custom-painted Stigmata at the Derby City Cup in Louisville before the final race in the Sho-Air US Cup-CX series.
Santa Cruz calls the Stigmata a “’cross, gravel, just go ride bike,” but for Ortenblad, it is his weapon of choice for racing on the cyclocross course. “The Stigmata rips,” the Santa Cruz / Donkey Label Racing rider said. “Santa Cruz really nailed the geometry on this bike.”
He continued, “I feel way too many companies are making the front ends of their bikes way too aggressive, like a road bike. This definitely makes them feel good when you’re dancing on the pedals up a smooth climb, but that’s not what ’cross is about. The front end has a perfect amount of [trail]. You can push the Stigmata into corners so hard and you know right where you’ll exit them. It’s almost like riding a 16-pound trail bike.”
Santa Cruz designed the Stigmata to take advantage of composite technology and the experience they gained making carbon mountain bikes. Although not the latest trend in cyclocross bikes, the Stigmata uses time-tested front and rear post mount brakes, a 12x142mm thru axle in the back and a 15x100mm thru axle on the fork. The frame ships with a Cane Creek 110 headset, and features a PF30 bottom bracket, a first for Santa Cruz.
Ortenblad rolls on Zipp 303 carbon tubular disc wheels with Donnelly tires glued up. Ortenblad’s wheels were set up with 140mm SRAM Centerline rotors, which Ortenblad prefers because of their decreased bite. In Louisville, he ran 700x33c intermediate-tread MXP tires modified to clear mud more effectively.
Zipp also provides the cockpit. Ortenblad’s bike features a Zipp Service Course SL stem, Service Course compact aluminum handlebar and an SL Speed carbon seatpost.
While carbon rails are not the most common thing on cyclocross bikes, Ortenblad has had no problems with his SL8 carbon cross country saddle. “I saw the SL8 saddle two years ago and picked it up off the counter and said, ‘Wow, this is insanely light!’ We put them on all the ’cross bikes and haven’t had an issue with them, so we just keep abusing them and they keep taking it,” he told Cyclocross Magazine.
Zipp parent company SRAM provides the drivetrain, outfitting the bike with a Force CX1 groupset. The Force HydroR brake levers are connected to Force post mount calipers, which feature 18mm pistons and organic brake pads. Ortenblad’s Force 1 rear derailleur features a clutch to prevent chain de-tensioning which could cause chain drop on a 1x system. The 175mm carbon cranks are fitted with a 42-tooth X-Sync chainring. Ortenblad uses the top-end Crank Brothers Candy 11 titanium pedals.
