The new mountain bike playground, Jubes, has at last been officially opened.

The opening ceremony was due to take place in September, but had to be cancelled due to bad weather.

The rescheduled ceremony which was held on October 17 attracted hundreds of cyclists and local residents who watched bike demonstrations and tried the park for themselves for the first time.

“With the growing popularity of mountain biking, this great facility meets the community’s needs and is a fantastic way to get active in the beautiful bushland setting of Wahroonga,” Ku-ring-gai Mayor Jennifer Anderson said.

Benjamin Hay was the winner of the competition to name the new park.

He suggested Jubes (it is located in Golden Jubilee playing fields ) and won a bike hamper for his trouble.

Jubes Mountain Bike Park is located off Esk St, Wahroonga.

Singletracks.com - Elka Stage 5 MTB Shock Review

Comments: 0

Great review from the guys at singletracks.com;

I love having the opportunity to check out cool and exciting new MTB products, especially those from smaller niche manufacturers. Elka suspension opened its doors in Quebec, Canada back in 2000, starting out in the performance / racing ATV market. The company has now grown into a multi-discipline manufacturer but mountain bikers still get all the individual attention and professional support that only a pro racer would expect.

The Elka Stage 5 is a 4-way adjustable rear shock ranging in sizes from 7.5″ x 2″ all the way to 10.5″ x 3.5″, covering nearly all the AM-DH bikes that are out there.  The shining feature here is the bike-specific custom valving, a feature that no other manufacturer I know of provides standard. The shock is constructed using hard anodized machined aluminum on the body, main shaft, main piston and reservoir and features easy to use adjustments with a wide range of tuning. The clickers all have a very positive feel to them with no need for tools to turn them.

Due to the high-flowing internals of the shock, Elka uses a high-volume external reservoir to ensure adequate internal oil flow. To guarantee a long service life, Elka included long life premium seals, O-rings and wear bands in the internals of the shock plus DU bushing for the eyelets and a quality micro-cellular urethane bumper. As an added bonus, Elka didn’t want to re-invent the wheel so they used standard spring and mounting hardware (1/2″ DU bushing hardware and 1.38″ inner diameter springs). Looking carefully on the outside you will also notice the razor perfect lines of CNC machine work. An optional titanium spring is available for those who are concerned about saving weight.

Internally there is a standard De Carbon main damping system (shim stack main piston). The shim stack can be easily tuned by Elka during production to fit each bike and rider’s needs. Upon delivery the rider can further tune the shock externally, with the two HSC / LSC concentric adjusters. The technicians at the Elka factory tune and calibrate to perfection with the perfect amount of low-speed damping, usually on the strong side, providing a suspension that is firm, nimble, stable and quick. Out of the box the shock tends to maintain the bike’s ride height, using less travel and maintaining stability.

On the high speed side of things, the exclusive high-speed compression circuit is in fact an adjustable progressive blow-off valve, based on a piston and shim stack design. A calibrated spring controls the initial resistance of the valves and the HSC knob changes the pre-load on that spring. The adjustment controls the threshold where the blow-off circuit opens to reduce the pressure building up in the shock upon impact. Since this circuit is parallel to the low-speed compression circuit, the transition between the “firm” state and the “plush” state is progressive and smooth and proportional to the force of the impact. Elka’s rebound circuit is a shim stack that is speed-sensitive.

Having run the Stage 5 for a few months now I’ve decided this rear shock is one of my top three favorites (though it’s hard to say which of those three is the best!). Since the Stage 5 has a ton of settings, it’s important to follow the correct procedure when setting it up. After installing the shock, set the sag (assuming you have the correct spring rate) by adjusting the spring collar. Usually 2 – 3 turns maximum will do the job. If you find you’re turning more than 5 that is a good indication that your spring rate is too low.

After setting the sag it’s off to the slopes for testing! What I have found that works for me is setting everything at one third the total range. Doing this forgoes possible endos and other nasty things when you have way too little rebound.  At this point I focus on the things a rear shock should handle: cornering, hits (both big and small), and straightline stability. That’s a tall order but it’s what all the suspension manufacturers have to contend with!

When I dial in a shock I tend to set rebound first followed by low and high speed compression. The key is to do only one at a time until you’re satisfied. When setting rebound you’re looking to get to a point where the wheel maintains traction (contact with the ground) but does not pack up (lose travel after a series of bumps). Rebound takes care of the dreaded bronco-style rides that can result when the setting is way too low. I ended up having my rebound set at 23 clicks (out of 30) from full soft (pretty active).

Low speed compression (LSC) takes care of things like rolling hills and rider inputs (pedaling) and corner entry. I rode a series of high speed berm turns and flats to jumps to get the attitude and level of control I wanted. I wanted my bike to be sensitive enough that I felt the ground beneath me without too harsh of a ride (chatter). I also tried off-the-saddle sprints when pedaling to jumps and I ended up with 17 click of adjustment (out of 22).

Finally I set the high speed compression (HSC), and based on the recommendation from Patrick at Elka I did my best to set up the shock with as little HSC as possible. Following the guide I started with no HSC and added 2 clicks at a time until I was satisfied that the bike was not bottoming out. Seeing that from slope to slope and park to park there are wild combinations of jumps and varying degrees of height, this is a setting that will see a lot of adjustment. With the slopes of Blue Mountain and my style of riding (I tend to land both wheels at the same time) I found a setting of 6-8 clicks (out of 22) was all I needed. The bike stayed in control, didn’t feel harsh, and as a few other riders who also tested out the bike said, it was amazing.

So check out Elka and contract them if you’re looking for a near-custom valved shock for your AM – DH rig. Elka’s ability to provide the individual service in itself is worth the $498 RRP

Thanks to Patrick and the folks at Elka for providing the Stage 5 for review.

Leaf Cycles Motostick Cranks review in AMB

The lattest issue of Australian Mountain Bike Magazine is now on the stands, make sure you go grab a copy and check out the Leaf Cycles Motostick Crank review.

 

Leaf Cycles Motosticks Full Review



"There are some areas of your bike that compromising on strength just isn’t intelligent. Your cranks are of these. Of course, if you can go strong without adding horrendous amounts of weight it’s even better. The new Motosticks crankset from Leaf are definitely a product that fits this ludicrously strong, kinda light description. They use a tubular steel construction, but the weight is less than most BMX-inspired cranks at 799g (plus bottom bracket). It’s their two piece construction that really appeals – rather than using a ‘floating’ axle like most BMX cranks, the axle is pressfitted into the right crank arm. This makes for a stronger connection, as well as making installation/removal much simpler, although you do need specific tools for the operation which must be purchased separately. It’s worth taking the time to get the spacing right first time around as the left hand crank fits so tightly to the axle that removing it to tweak the chainline is hard work (trust us). Speaking of the axle, it’s a beefy 19mm in diameter and uses a 48 tooth splined interface for huge contact area between the axle and crank arm. The bottom bracket houses four bearings for excellent axle support and better bearing durability. We’ve had these on our dirt jump bike for over six months now and we’ve not even had to give them a moment’s thought. No creaking, grinding, bending or other problems to speak of, which is impressive on a bike that gets used and neglected this much. When we went to pull them off the bike to check them out for this review the crank bolt was as tight as the day we installed it and the bottom bracket bearings felt like new. You can’t ask for more than that.

2011 Australian National MTB Championships

Comments: 1

The 2011 Specialized Australian National MTB Championships has kicked off to a great start. Last year CTN Imports was there in full support, and we were naming sponsors for the pump track and had a great day tour down in southern Australia. This year the champs have clashed with BMX games, however we didn't want to miss the opportunity to support all the good work that is done by the riders and event organisers. We are still going ahead with our sponsorship and have sent down some great goodies for the riders of the pump track, dirt jumps, 4x and also the downhillers. $100 gift vouchers will be given to winners and runners up of various events.

Eagle Champs Logo

We want to keep you updated so as Day 1 wrapped up last night, Day 2 is off to a great start today. Day one at the event went smoothly with Supprise entry Mick Hanna on the Downhill and Jared Graves returning to DH. The Pump track is getting lots of use and the 4x Track is now bunted and looking great.

The big screen is MASSIVE and the tunes are online. If you're not there already, make sure you get there!

Pump Track Winner

Last year's winner of the Leaf Cycles Pump Track was Connor Fearon, Adelaide local and DH racing machine! Walking away with an $875 frame sure is a nice way to spend your day.

This year Connor is in tight competition with rival Troy Brosnan from the I Am Specialized team to take out the crown.

The Pumptrack last year was the first one ever created at a DH national event. This year it's bigger and better, let's see who can handle the wrath and speed of Connor this time.
