1. When Norco began laying out the Aurum on paper what were the traits and strengths you were looking for the bike to have?
We were aiming to design the fastest possible downhill bike. To do this we paid special attention to wheel-path, leverage curves, braking performance and geometry.
2. Can you tell us a little about the custom hydroformed tubing you are using?
The Aurum frame uses double butted and formed aluminum for optimal strength, stiffness and weight. The frame’s curves are also functional, creating room for the shock, improved stand-over, heel clearance, chain clearance, caliper mounting, etc…
3. The Aurum features what is referred to as a Gravity Tune can you elaborate a bit on what it does and the benefits it provides? Is there anything a customer should keep in mind while setting up their new Aurum?
Gravity Tune ensures that all sizes of riders get equal and optimal handling characteristics. To do this we modify the front-centre and rear-centre within the frame’s front triangle to optimize the rider’s weight distribution.
4. With all the different suspension systems out what made you choose the FSR four bar for the Norco Aurum?
Norco has a strong belief in the Horst-Link as it offers superior square-edge bump absorption, optimum braking characteristics, lateral stiffness and great pedaling efficiency.
5. Can you elaborate some on the A.R.T. Suspension and explain a bit what was altered and why?
A.R.T. suspension is all about the rearward axle path. This helps the bike hold its momentum through rough terrain, helps the suspension remain active under braking and also improves pedal efficiently.
6. Was weight a very big concern when you went to create the Aurum bike? Do you know what the frame and shock weigh in it?
Weight is always a concern for any bike and the Aurum is no exception. Coming in at 7.5 lbs with a shock, the Aurum’s strength to weight ratio is something that we are very proud of.
7. The current crop of downhill bikes has undergone a slow evolution becoming
lighter, slacker and lower. Do you think we are approaching the magic set of
numbers for downhill bikes like MX bikes have had for years?
There will always be differences based on rider preference and suspension design but the variances are becoming less with every passing year. I believe that we are approaching a zone of perfection.
8. How do you think the three big suspension companies are doing with their most recent offerings of forks and shocks?
We have seen huge advancements over the past few years. Each manufacturer has stepped up their games and are pushing each other to remain competitive. The suspension technology available is getting better every year and will continue to improve moving forward.
9. What would you suggest to the suspension engineers to improve their products?
Mountain bike suspension could be improved through addressing durability and reliability. Weight reduction is another area to look at moving forward through the optimization of air springs in forks and shocks.
10. On future version can you see having adjustable BB, HA and chainstays or any form of chassis adjustment?
Not telling.
11. How long did it take to get the bike from Cad drawings to first production run?
The Aurum was a big push for Norco that we put a lot of resources into. Given the push we were able to move from a CAD model to a first production in a little over a year.
12. Who helped develop the frame?
The Aurum was a team effort. Our engineering team, product managers and team riders all had a great influence on the design and development of this bike.
13. How has the response been to the Aurum line?
Response to the Aurum has been extremely positive. Everyone who rides the Aurum raves about it.
14. What do you envision changing on the current Aurum frame over the next few years?
We are always striving for perfection and when it comes to the Aurum that means making it faster. Wait and see.
15. Any other thoughts or things we should know about the frame?
Go ride one and find out for yourself.
