The Aurum HSP was created for one single purpose: to be the fastest downhill mountain bike available. The Aurum HSP's full carbon frame is engineered for maximum strength and increased vibration damping at speed. The High Single Pivot suspension relies on precision kinematics and a chain idler wheel to ensure the suspension absorbs any obstacle between you and victory, while remaining unaffected by drivetrain forces. The adjustable reach ensures easy adjustment for rider fit or preference. Available in both 27.5 and 29" models, the Aurum HSP features Norco's Gravity Tune geometry to provide the same ride characteristics and weight balance across all three frame sizes. Starting with this world-class frame, you get to determine every detail and scrutinize every part in building your ultimate descender to power around every corner and across the finish line for your time in the Hot Seat.
A modern day trail bike engineered to go fast, get loose, and have fun.
Poise and grace aren't typically used to describe a blazing DH run, but one ride aboard Norco's Aurum will have you stoked about the refined composure of this speed fiend's character. Precision carbon fiber engineering gives the Aurum's frame loads of stiffness for pinpoint control, while the RockShox Vivid RC2C Coil rear shock returns a supple, planted feel and big-hit capability when you need it most. The Aurum — Latin for “gold” — earned its name by turning the most challenging terrain features into advantages over other riders. Devour steep, gnarly sections with high-speed control and push your limits whether you’re doing park laps or racing against the clock.
The Aurum HSP was designed with a single purpose: to be the fastest downhill bike Norco has ever made. As an integral bike within Norco’s Race Development Program, the Aurum HSP’s proprietary design was developed and tested by Norco engineering in conjunction with the Norco Factory Racing Team. After a full year of testing and riding, including a complete UCI World Cup Downhill season, the result is a no-compromise DH race machine that delivers superior grip and control, capable of taking on the toughest tracks in the world in pursuit of gold. - Aurum HSP Full Carbon Frame: Lightweight and durable full carbon fiber frame for improved stiffness-to-weight ratio, increased vibration damping and maximum strength - Gravity Tune: Ensures optimal body position and ideal front/rear weight distribution for riders of all sizes to deliver superior handling and control at high speeds - A.R.T. Suspension: The most extreme iteration of Norco’s proven A.R.T. suspension philosophy to date. Optimized for DH race purposes delivering superior grip, support, and control on steep and rough terrain - Adjustable Front Center: Allows riders to make easy adjustments to the bike’s front center and wheelbase length for quick and easy fit and setup tuning - 27.5" or 29” wheels: offering M-XL riders a choice of wheel sizes to further fine-tune handling characteristics based on their riding style
Poise and grace aren't typically used to describe a blazing DH run, but one ride aboard Norco's Aurum might have you stoked about the refined composure of this speed fiend's character. 27.5-inch wheels provide a quick and stable foundation, while precision carbon fiber engineering gives the Aurum's frame loads of stiffness for pinpoint control. Norco chose to design the Aurum around the real-world benefits of a 7-speed cassette, using 142mm rear axle spacing to optimize the chainline and increase heel clearance, while keeping tighter gear ratios for race-winning runs. The Aurum C7.1 Framekit includes a Fox Float X2 Factory rear shock and Norco 142x12 thru axle.

The Big Fat Dummy is a long tail cargo bike that took a few too many doses of growth hormones. At first glance, you might say that Surly just put bigger tires on a Big Dummy. But if you said that, you'd actually be very wrong so just… don't. Think of Big Fat Dummy as more of a second or third cousin to Big Dummy rather than a brother. They share some of the same DNA and look sort of similar, but they're two very different bikes and really only interact when they both reach for the potato salad spoon at that family reunion that no one really wants to be at anyway. Now that that's out of the way, let's get down to the nitty gritty of what makes this hulking beast of a bike tick. Surly's goal with designing a cargo bike around fat tires was to create the most stable, stiff, and traction-laden ride possible while hauling a ton of stuff. Big Fat Dummy has a longer toptube and slacker headtube than its more svelt cousin giving it a nice, predictable, and stable ride. They also used thinner, lighter tubing to construct its cargo area so while it's an overall burlier bike, there's not much difference in weight. Big Fat Dummy accepts either 10mm or 12mm axles in the rear with a spacing of 190/197mm. That big ‘ol spacing equates to one thing: tire clearance for days. Big Fat Dummy maxes out at a massive 26 x 5.25" tire.* While that large of a tire provides the most traction and stability a bike can possibly offer, it's also a lot of rubber to push and might not be for everybody. Luckily, Big Fat Dummy is also a blast to ride with 3" tires too. It uses the same 100mm suspension-corrected fork as the Wednesday, meaning if you want to add a little squishy-squishy to your ride, you can throw a Bluto on and let ‘er rip. If you intend to carry a passenger on your Big Fat Dummy, Surly requires use of their Dummy Rail Collars. These provide a secondary retention system for the rack, as well as stiffen the rack system. In addition, a stoker handlebar set up, found on tandem bicycles, is recommended as well. Make sure to check with seat post manufacturer for stoker handlebar compatibility. All Big Fat Dummy framesets and bikes ship with a Dummy deck, rails, bags, and the aforementioned Dummy Rail Collars so you can immediately start hauling cargo — human or otherwise. Big Fat Dummy is ready and willing to carry all sorts of crap — literally. It's already in use on an organic farm in Ecuador so it's likely that it's hauled some form of manure by now. *Using a 26 x 5.25" tire will cause some drivetrain limitations. For all the nuts and bolts of compatibility read Surly's blog on the subject.
Developed in collaboration with Norco Factory Racing, the Aurum’s World-Cup racing heritage will put any gravity junkie or passionate DH racer in the hot seat — at races and with your buddies during a day at the park. The Aurum A1 features Gravity Tune, with rear-center lengths that increase proportionately to the front center length for each frame size, achieving optimal body position and weight distribution for superior handling and control. The 6060-T6 frame includes strategic frame armor and integrated fork bump stops, with fender and shuttle guards for protection from day to day high speed riding and surprise get-offs. Designed around 27.5” wheels for strength and stiffness, the Aurum A1 has 142mm rear axle spacing and an 83mm BB shell for ideal chainline with DH drivetrains, and provides 200mm of supple travel with its Fox Performance Vanilla LSC rear shock. Because so many riders have their own preference for wheels, forks, drivetrain and brakes, we’ve made the frame available on its own to build your ultimate dream park rig!
Want to see what you're capable of? First, you need a bike to get you there. Get started with Norco's Range Carbon 7.3 Framekit. Its lightweight carbon frame is seriously stiff for inspired cornering and wonderful responsiveness, while the 650B wheels increase traction and hold momentum like a 29er, yet are quick, playful and strong like 26-inch hoops. Out back you've got 160mm of Norco's legendary A.R.T suspension so you'll have the confidence and control to barrel into anything full speed. Oh yeah, that's all driven by a Cane Creek Double Barrel shock for maximum trail steeze. The 7.3 framekit has the mount for a front derailleur, so it's all ready to go for 2x or 1x systems.
Norco’s Aurum Carbon 7.1 is here to blast backwoods shuttle runs, laps in the park, and World Cup courses alike. Its super-responsive, lightweight carbon frame uses race-proven geometry to rip corners and maintain stability when tackling some of the nastiest tracks on earth. Norco knows that DH bikes experience some of the roughest riding conditions, so they incorporate Armorlite resin and integrated frame guards throughout to bolster impact resistance, meaning you can focus on taking the fastest line, not necessarily the safest. Norco’s A.R.T. rear suspension with Gravity Tune powers Cane Creek’s insanely adjustable Double Barrel coil shock for a perfect blend of big-hit compliance with pedaling efficiency. Build up the Aurum Carbon 7.1 and get ready for the ride of your life!
