Ride report by Sven Martin // Photos by Adrian Marcoux and Sven Martin

Last year was quite a year for SRAM with the widespread adoption of their 1X drivetrain technologies. From Nino Schurter winning XC World Champs and the overall title to Jerome Clementz winning the Enduro World Series and even Kyle Strait and Cam Zink with their freeride performances at Red Bull Rampage, it’s about time we can reap the benefits in DH too. Today SRAM is officially launching the 7-speed X01 DH drivetrain - the same system Steve Smith used as he marched to a last minute 2013 World Cup Downhill Championship.

Welcome to Queenstown, New Zealand. This is the Remarkables Range at sunrise. Jet lag isn’t so bad after all.

With the delayed winter storms finally hitting the North Hemisphere with rain, snow and deep freezes, the Southern Hemisphere is a good place to be right now. What better destination than Queenstown, New Zealand to test out the soon to be available DH groupset? Long sunny days offering the perfect riding temperatures for the multitude of trails and types of riding are on offer. Queenstown, with the Skyline Gondola and their trail network and easy access to some World Class terrain, made it a logical choice for SRAM’s annual Trail House adventure. They invited a couple of us journalists to spend some time getting to know the products and trails and each other over a relaxing few days. Late wake up calls but long days on the bike and good food and drinks hot and cold all around.

Queenstown has a lot to offer any rider. DH, DJ, freeride and of course XC/trail/enduro. From the peak there are two tracks, one of which is more forgiving with less fall line and more turns allowing for better testing of the gears into and out of corners and on long rough straight aways.

Unluckily for me I already live in New Zealand and was making my way over from Chile after the Andes Pacifico Enduro. This meant I was to miss the first day of bike park fun and while others slept in I was plagued with 4AM jet lag induced early wake ups. This does however have an upside as I contemplated life and bikes over fresh coffee in the predawn hours watching the pink glow and light show of the sunrise over Lake Wakitipo from the deck of the awesomely situated SRAM Trail House.

I’m not a huge geeky product tester and I’m not super into all the stats and numbers, but I’m a big fan of real world situations. For me to draw any real world test comparison I like to base my experience on familiar trails. Being based in New Zealand means lots of trips to Queenstown for the riding and racing each summer, so I was happy to learn we would be riding Rude Rock which I have ridden many times before on both my trail bike with XX1 and my DH bike with 10-speed Type 2 SRAM derailleurs. In other words, a perfect track for subjective comparative testing.

It always feels good to get a ride on a brand new bike. Fresh rubber and the works. When I set up the bike on a deck that overlooks the beautiful Lake Wakatipu, it was hard to actually leave and go out for a ride.

The bike was a Devinci Wilson set up much like Steve Smith’s was for his World Cup Series winning season, complete with the new X01 DH drivetrain. Super grippy, confidence inspiring soft compound Schwalbe Magic Mary DH tires and perfectly custom tuned suspension made getting used to a new bike a breeze.


The 7-speed Mini Block X-DOME cassette has a 10-24 range and is the lightest cassette on the market. It’s compatible with wheels that can fit the XD driver body, and the space between the gears and spokes gives more safety clearance. Up front my test bike used a X-SYNC 34-tooth chainring. This gear range allowed me to still make the two pinch climbs that proceed the beginning of the Rude Rock track.

Even with the smaller 34-tooth ring up front (compared to my current 10-speed DH bike with a 36-tooth front and traditional 11-26 cassette) I could also push a harder gear at the other end of the cassette while having a touch more clearance. Make sense? Basically a bigger overall gear range than I had with fewer gears and a smaller front ring. Those really wanting to take advantage of that extra clearance have the option to go guide-less or to install a slightly smaller guide. The front chainring features the same alternating thick/thin X-SYNC tooth profile that has been so successful in XX1.

Mongo Scrub. Sometimes you feel really pro following Blenkinsop, mimicking his cat like scrubs on Rude Rock. Then reality sets in when you look at the photos and see there is a lot on room for improvement. #tuckyourknees

But what of the ride itself? Well Rude Rock is not a full on steep DH track, so that combined with the amount of traffic (and thus brake bumps) makes it a good track to test out shifting and drivetrain performance. It still has some steeps and flying fast sections but there are more than a few flat turns and blind rises. This adds up to plenty of sections to test up and downshifting, all while riding fast bumpy terrain.

Between and rock and a hard place. The Rude Rock (see rock feature in background) trail is great for both DH and trail bikes and has hosted races for both.

As I dropped in, out of habit I immediately made the mistake of dumping a bunch of gears in the first steep shoot like I would normally do on my own 10-speed setup. This isn’t necessary anymore. Each gear shift up and down is a much bigger ratio, and using half the amount of shifts to go through the same range of gears makes it a lot easier for precise gearshifts to match the changing terrain. Less shifts also means less mental fatigue on memorizing multiple shift points while racing and making sure you are in the right gear. It was surprisingly simple to adapt to, mostly because it just feels so right. Finally we have a production drivetrain with fewer gears - something we have been asking for and some of us have been custom doing for several years now. But the benefits of X01 DH extend far beyond just fewer gears and a better range.

Before Steve Smith blew his ankle on a gap that he couldn’t resist (SENDER STEVE STILL LIVES), he felt right at home in Skyline bike park. A mix of pine and native forest and some open trails with scenic backdrops make this a perfect place to visit or train in during the cold northern winters.

Perhaps the biggest benefit you feel is the precise, crisp, tight shifting even in the roughest and chattery of surfaces. That and the disappearance of ghost shifting under heavy pedal load in the same situations add up to a remarkably less clunky experience on the DH bike. You can pedal your way through each gear shift without a break in your cadence or second thought, and you know that when you start pedaling it won’t immediately slip like so many DH bikes often do.

This is likely a result of the whole system being designed under the “all for one” philosophy. Each component is designed to work better with the next, all offering separate benefits individually and a much better ride experience collectively. X-SYNC in the chainrings and pulley wheels of the derailleur provide maximum chain control - the tall square edge teeth, rounded chamfers and thick/thin tooth geometry grab the chain earlier and hold it longer. The recesses also allow the chain to get rid of mud (which we got none of) easier. The new X01 DH X-HORIZON derailleur, which only moves in a horizontal direction, eliminates vertical movement of the derailleur when smashing through the rough stuff, giving you faster shifts and no ghost shifting. This is a huge benefit, especially for racers. Combined with the Roller Bearing Clutch the system is very quiet, too. This is where this system really shines if you are looking for performance gains. There are a whole lot of other features, advantages and benefits like weight savings, reduced friction surfaces, mud shedding, spoke clearance, etc, but for me the two that I’m sold on are the gear range and the performance advantages with the X-SYNC and X-HORIZON. That’s enough for me right there.

SRAM's Chris Hilton drops into Skippers Canyon, one hell of a long ride.

For those that have just upgraded to 10-speed and not ready to sink money into a whole new drivetrain, fear not. SRAM have also made the derailleur available in a 10-speed configuration. Why upgrade from a clutched system? That horizontal derailleur movement is the key, and it really does make a remarkable difference on a DH bike.

When SRAM first introduced XX1 it was clear that there were a lot of potential benefits that would be applicable to downhill. It’s great to see this system come to life. This is what downhillers have been asking for for years, but done far better than we ever expected.

It wouldn't be a SRAM ride without good coffee in the beginning and cold beers at the end. Too bad they weren't Sprig and Ferns Pilsners. While Blenki abstains as he is in training, Boris (MBR Germany), Ed (Dirt UK) and I cheers bru and sink a few. Cheers to SRAM for another great Trail House adventure.
