Guerrilla Gravity DH (GGDH) Updates

GG has done some updating to their GGDH. They have gone the 650b route, added rear tire clearance, and made the frame a tad bit longer.

GGDH Updates

  • Park Mode is the shorter travel, lower BB, and more progressive mode. This mode is ideal for jump lines and riders who thrive on a more playful, poppy platform.

  • Race Mode is the longer travel, higher BB, and more linear mode. This mode is for smashing through rock gardens and riding the absolute steepest terrain you can find.

  • Improved tire clearance now provides a very roomy 12 mm per side with a Maxxis 2.4 DH tire, more than double the EN required amount

  • Longer front-center to ensure continuity between their other bike models for given rider height

  • Ever important frame color choices--10 frame colors and 6 decal colors are available, allowing riders to build something unique to them

 

GGDH Features 

  • 203 mm (8") rear travel
  • Dual modes adjusted via shock mount
    • Race Mode
    • Park Mode
  • Threaded bottom bracket, greatly reduces creaking and loosening (vs press fit)
  • Massive 25mm pivot axle
  • Zero Free Play pivot and axle interfaces
  • Premium Enduro dual-lip sealed cartridge bearings
  • 7.9 lbs. (3,583g) frame with hardware (size Medium, no shock)

GGDH Specs

  • 30.9 mm seatpost (34.9 mm clamp)
  • 1.5" head tube (49 SHIS - compatible with all steerer tubes and the Cane Creek Angleset)
  • ISCG05 chainguide mount
  • 148 mm rear wheel spacing
  • 83 mm bottom bracket spacing
  • 240x76 mm shock
  • Max tire size: 27.5 x 2.5

SIX NEW RIMS AND WHEELSETS FROM IBIS

Two years ago, Ibis introduced the ultra-wide 41mm 741 and 941 wheels to a few raised eyebrows. Once people rode the wheels and experienced all the benefits, those raised eyebrows quickly became high fives. Elbow pad sales spiked due to the massive traction of the wheels, as lean angles to approached 90°. OK, we made that part up but you get the idea.

4 In Carbon Fibre

  • New Asymmetric Profile Carbon Fiber Rims
  • Lower Profile Nets a 30% Increase in Impact Strength
  • Less Material Saves 7.5% Weight
  • Industry Nine Hubs Machined in USA
  • Boost Front and Rear
  • SRAM XD or Shimano Drivers
  • 27.5" and 29" in 41mm and 35mm Outer Widths
  • Wheels Built in USA
  • Available May 1, 2016
  • Wheelsets $1799

 

2 In Aluminum

  • Asymmetric Profile 6066 Aluminum Rims
  • New Super Durable Ibis Hubs
  • Work Great with Plus Tires
  • Boost Front and Rear
  • SRAM XD or Shimano Drivers
  • 27.5" and 29" in 38mm Outer and 35mm Inner Widths
  • Available May 15, 2016
  • Wheelsets $549

 

With the 742/942, we’ve retained the 41mm outer/35mm inner widths of our 741/941 rims, while increasing impact strength, reducing weight and maintaining all-important lateral stiffness.

The 735/935 feature 35mm outer and 29mm internal rim widths. The 735/935 are ideal for lighter trail bikes that see more XC time, and also great for riders looking to save as much weight as possible, while taking advantages of the features that wide rims bring you.

Our new carbon rim design features a lower cross section height for increased impact performance.  The lower 19.5mm section height makes the wheel better able to distribute the loads of localized impacts from rock strikes or hard landings.

Also, we are introducing a new hybrid carbon fiber layup, strategically combining layers of a new, high-toughness carbon/epoxy prepreg with our original carbon composite, increasing both ultimate strength and impact durability.  This, combined with the asymmetric rim design that features 5mm of offset (2.5mm on 735/935)  allows for higher spoke tensions that are nearly equal from one side of the wheel to the other. As a result of all this, the 742/942 nets a 30% increase in impact strength yet a 7.5% decrease in weight, compared to our previous rims.

Our carbon wheels now come with the excellent Industry Nine Torch hubs. The durable hubs are made in the USA in Industry Nine's Asheville machine shop, and feature a 60t ratchet with 6 out of phase pawls that results in a 3º engagement. They are equipped with Enduro bearings and come with either Shimano or SRAM XD drivers.

A wider rim delivers better sidewall support so in many cases you can run lower pressures in your rubber. Tires mounted on wider rims don’t burp as easily. Lower pressures, even a pound or two, do several beneficial things, including increasing the contact patch, which results in better traction. Running lower pressures on varied terrain actually reduces rolling resistance. Wider rims are stronger and stiffer. With increased traction comes increased braking control.

The 742/942/738/938 rims are ideal for the ultra low pressures (10-18 psi) that we like to run with 2.8 Plus tires (or 18-25psi for 2.25" - 2.5" tires). Running any of our 35mm internal width rims work incredibly well with the new 2.8 Plus rubber we've been riding from Schwalbe and Maxxis. The low system weight of the wheels with these rims and tires combined with the monstrous traction advantage have been a revelation for those who have ridden them.

We've also had great luck with the 3.0 tires on the rims, and our tire manufacturing friends have informed us that there are a lot of new Plus tires in the pipeline.

Wide Rim Benefits

  • Dramatically increased traction
  • Reduced rolling resistance
  • Less tubeless ‘burping’
  • Works well with Plus tires up to 3.0"
  • Stiffer, stronger wheel
  • lighter than most narrow aluminum rims
  • Better braking control
  • Improved flat protection
  • More predictable feel
  • You can run a lighter tire with similar durability
  • Hookless bead rims are far stronger
  • Easy to mount tubeless with just a floor pump

 About Ibis Wheels

Our new carbon wheels feature all the good points about our prior wheelsets, with a few bonus features. The asymmetric design with offset spoke holes allows us to build a wheel with identical spoke lengths on the drive and non-drive side. The spoke tension is evened out between the two sides this way, building a more durable wheel. We are using a new hybrid carbon layup as well, layering a new high-toughness carbon/epoxy prepreg with our original  carbon composite, which increases  both ultimate strength and impact durability. So they are lighter and they are stronger.

Our new carbon wheels come with the excellent Industry Nine Torch Hubs. The hubs are made in the USA in Industry Nine's Asheville machine shop, and feature a 60t ratchet with 6 out of phase pawls that results in a 3º engagement. They are equipped with Enduro bearings and come with either Shimano or SRAM XD drivers.

The 742/942/738/938 rims are ideal for the ultra low pressures (10-18 psi) that we like to run with 2.8 Plus tires. They also do wonderful things to the performance of a number of 2.25” - 2.5” tires that start with fairly rounded profiles. We run lower pressures in 2.25-2.5” tires with the wider rims as well, in the neighborhood of 18-25 psi depending on rider weight and riding conditions.

Rocky Mountain Launches The 2016 Pipeline 27.5+

Features

  • Wheel Size: 27.5+
  • Intended Use: Aggressive Trail
  • Front Travel: 150mm
  • Rear Travel: 130mm
  • Smoothwall carbon front triangle, FORM alloy rear triangle.
  • Fits up to 27.5x3.25 tires.
  • 1x specific.
  • Lightweight bolt-on axles save 50g per bike compared to a Maxle.
  • BC2™ pivots feature grease ports for easy maintenance.
  • Stealth dropper post equipped.
  • Internal cable routing.
  • PressFit BB92 bottom bracket, IS42/IS52 headset, Boost axle spacing.
  • Sizing: S/M/L/XL

The confidence of plus-sized tires in raw, technical terrain is now available in an aggressive trail chassis. The new Pipeline plows through greasy roots and square-edged chunder with authority, while providing near limitless traction on rocky, slippery climbs.

“Early on in testing I realized I could take the ‘stupid lines’ on our local North Shore trails and the big tires would just flow straight through them,” said product manager Ken Perras. “The more technical a line, the more I felt like I was cheating.”

Geometry

The Pipeline is based on our much-loved Instinct platform. Like the Instinct, the Pipeline is stable and balanced, with a massive range of adjustments available thanks to RIDE-9. A neutral bottom bracket drop and plus-specific fork offset contribute to an intuitive ride feel with excellent steering dynamics.

Wheels

Riders attacking technical, choppy terrain will immediately feel the benefits of high-volume plus tires. Their large contact patch and lower pressures improve traction, mud shedding, and small-bump compliance for more on-trail confidence.

Technologies

  • The RIDE-9™ system allows riders to adjust geometry and suspension rates to specific riding styles, terrain, and rider weights. Nine configurations are possible thanks to two interlocking chip inserts that move on two separate axes.
  • Smoothwall™ carbon uses one of the world’s most sophisticated carbon processes to build frames with industry leading stiffness-to-weight, ride quality, and durability. By using rigid internal molds, we are able to perfect the shape of the internal features and eliminate excess materials. We use different types of carbon in specific frame areas to maximize stiffness and impact resistance while minimizing overall weight.
  • FORM™ alloy tubesets are engineered for specific purposes within each frame, ensuring optimized strength, weight, and ride quality. FORM™ tubesets use premium materials to meet our strict requirements.
  • Smoothlink™ suspension stays supple yet supportive through a wider range of gears than conventional single pivot or other four-bar suspension configurations. This patented system reduces both pedal-bob and bottom-outs, while allowing us to fine tune variables like braking and climbing traction across a wide range of intended uses.
  • BC2™ pivots are lighter and stiffer than conventional bearing pivots. Unlike other bushings, our patented system uses a hardened alloy insert that bottoms out to control the contact of the bushing surfaces, reducing the preload that causes stiction and binding. BC2™ Pivots also feature grease ports for effortless maintenance.

Wade Simmons finally speaks out on what he calls the "de-gnarification" of Vancouver's North Shore.

AARON GWIN WINS DEBUT WORLD CUP FOR THE YT MOB IN LOURDES

Reigning World Cup Champion Aaron Gwin scored a historic win for his new team’s title sponsor, YT Industries, by taking their TUES CF Downhill bike to a maiden victory on the slopes of the Pyrenees on the outskirts of Lourdes France. The opening round of the UCI Mountain Bike World Cup, the 24th season of the series, presented plenty of challenges throughout the week due to changeable weather conditions.

Despite the sunny weather on race day, threats of a looming storm late in the afternoon certainly gave everyone something to think about as Aaron went up the hill to start his race. His win last year on this course was in extremely dry and dusty conditions, far from today’s track conditions, so to walk away with a podium result would have been a great start for the new team. After the first split it was clear that Aaron was on a great run, building on his lead throughout each of the 4 sectors before finally crossing the line with a 3m 09.131secs, some 2.7secs faster than previous fastest Danny Hart (GBR).


Nine riders were left to come down but all eyes were waiting on crowd favourite and World Champion, Loic Bruni of France. Bruni was showing incredible pace and was up on the first 3 splits but a small mistake was a sign of things to come as he pushed a little too hard towards the bottom and came off his bike. The win was Aaron’s. In fact, this was Aaron’s 50th World Cup start, his 30th podium, of which 15 have been wins.


Aaron said: “I’m so stoked to win the first round of the year with the new team. This week was especially challenging for everyone on the mountain due to the changing weather conditions, nearly every run was different, so to have it all come together on race day is really cool. I want to say a big thank you to the team staff, everyone at YT, and all of our team sponsors. We put in a ton of work in the offseason to get us ready for the races and it’s awesome to see it all come together so well. Really looking forward to the rest of the season; this was a great start and I believe we’ll continue to get stronger from here!”


Aaron’s team mate Angel Suarez had a tough week and after a heavy crash on a Saturday practice run and was suffering from a sore back. Unable to complete his second practice run he went straight into qualifying but was unable to ride at his limit and just missed out on the top 80.


The team now prepares for Round 2 in Cairns, Australia, on April 22 and 23.
