Cycling manufacturer Shimano has issued a global review of one of its most prolific bike parts after widespread reports of malfunction and injury.

Key points:

    • Bicycle part manufacturer Shimano has issued a global review of its cranksets

    • There have been long-running complaints about the crank arm splitting from the body of the bike, causing crash risks

    • The review was only launched after an investigation in the United States found the fault potentially contributed to a serious accident

At least 2.8 million cranksets globally are set to be the subject of an inspection and review program launched this week by Shimano, the largest manufacturer of bicycle components in the world.

It follows investigations by product safety agencies in the United States and the European Union after more than 4,500 complaints were made in just over a decade about the cranksets failing riders.

The crankset, or ‘crank’, is the part that connects a bike’s chain to the arm of its pedal.

But Shimano’s Hollowtech II model has become notorious for problems with its adhesion corroding over time, forcing the crank arm to split when pressure is applied to the pedal.

Since learning of the widespread problem, cyclist Henry Strong noticed his Shimao crankset was among those that had started splitting.(ABC News: Jade Toomey)

Canberra cyclist Henry Strong owns two sets of the affected cranks, and said it was frightening to be using potentially faulty equipment while cycling at high speeds.

“The feeling that you might have faulty equipment when you’re doing 75 or 80 kilometres [per hour], that’s quite terrifying,” he said.

“When you’re cycling, something going wrong could, of course, be fatal.”

The issue has been the subject of long-running online forums and dedicated social media pages.

Canberra bike mechanic Stuart Carling said the faulty equipment should have been recognised earlier.

“I don’t think I’ve seen [a recall] like this in this industry, it’s huge, it affects potentially thousands and thousands of people,” he said.

“This is something that should have been recognised years ago.”

Mr Carling counted eight bikes affected by the problem in his small bike workshop in Canberra, even though they were originally being repaired for different issues.

Shimano said it had not been able to determine the cause of the issue, but had now acted on the complaints after a US Product Safety Commission investigation found the fault could have contributed to a serious accident involving an American rider.

“We are deeply sorry that any riders have been affected by this issue,” a Shimano spokesperson said.

Shimano’s Australian branch declined to reveal how many complaints it had received about the issue, and how many units it anticipated were affected in Australia.

The company said it would launch an app in October to facilitate its replacements.

“But it’s too little too late, if you ask me,” Mr Strong said.

“You’ve already had thousands of people that have had incidents, many broken bones, some people hospitalised.

“It appears as though they’ve finally come to the point where they have to acknowledge it, but I think they should have done it a lot sooner.”

Mr Strong, who competes in triathlons, will not be able to use his bike without a replacement before the first race of the upcoming season in two weeks.

“I don’t feel particularly safe using this equipment,” he said.

“We trust that the equipment we buy and invest in will support us, and will be reliable and meet a certain standard.

“I think Shimano has failed to meet that standard by continuing to manufacture and sell faulty equipment for close to 11 years.”

Riders are directed to get their bike inspected at a Shimano dealer, who will decide if it needs to be replaced.

Mr Carling said he was bracing for an influx, but questions about who would pay to fix the issue remained.

“I don’t believe that should be the customer, it is probably going to have to fall back on Shimano, but how are they going to do that?” Mr Carling asked.

A spokesperson for the Australian Competition & Consumer Commission (ACCC) said it was aware of the recall in the US and EU, and that Shimano Australia had commenced an inspection and replacement program for affected cranksets.

“If a supplier becomes aware of a death or serious injury/illness caused by a product they supply, the supplier must make a mandatory report through the Product Safety Australia website,” the spokesperson said.

Shoalhaven Bicycle User Group 25th Anniversary Silver Celebration

Tips for Group Riding from Bicycle NSW


Riding in a group is an exciting experience and can lead to some amazing adventures! St George BUG has come up with some helpful hints to ensure everyone remains safe and has a fun time.

Bike riders cycling together


  • Your bicycle should be in good working order, with tyres pumped and chain oiled. 
  • Do not ride if your brakes are defective.
  • You must wear a helmet – it’s the law.
  • Take a full drink bottle of water and be sure to drink regularly. 
  • Wear suitable clothing – a brightly coloured top is advisable. 
  • Carry a spare tube which is the correct fit for your tyre, a pump and tyre levers. 
  • If the ride is in the early morning or evening, make sure you have front and rear lights. 
  •  A mirror on your handlebar or wrist is an advantage. 
  • A bell is very necessary when riding on shared cycle paths. 
  • Use sunscreen when appropriate – you’ll probably be out in the sun for a few hours.

Riding Etiquette

  • If you haven’t ridden with a group before, let the group know, so they don’t ride too close to you. 
  • Listen carefully to the ride leader’s instructions at the start of the ride. 
  • Watch for hand signals from riders in front of you, e.g. left and right hand turns, slowing or stopping, debris or potholes on the road. The ride leader will show you the signals. 
  • Pass on the signals to the riders behind you, or call them out if you are unable to do them. 
  • Call out “bollard” when approaching one as you might block it from the vision of riders behind you. 
  • Keep to the left when riding, so others can pass you if necessary. 
  • If you pass a rider or walker, call out “passing”.
  • When riding on a road single file is preferred. If the sweep calls out “car back”, it means a car needs to pass, so make sure you keep to the left in single file. 
  • When approaching a roundabout, check behind to see if the road is clear, then take the middle of the lane to go into the roundabout so you don’t get nudged to the side if a car tries to pass. 
  • Always stop for red lights even if the riders ahead have gone through. They will wait for you. 
  • Don’t shout abuse at pedestrians, cyclists or motorists or use rude gestures. 
  • Remember that pedestrians have right of way on most shared paths. 
  • If the group has stopped to wait for you, don’t ride up to the front of the group, but join the back of the group.

Avoiding Accidents

  • Always move yourself and your bike to the left edge of the path when you stop. Not only does this avoid riders colliding with you, it also stops others who use the path from getting annoyed. 
  • Don’t swerve in and out of the group. 
  • Bollards come in all shapes and sizes. Watch out for them on shared paths, slow down and call out to riders behind you to alert them. 
  • When riding up onto a footpath or across a gutter, always approach at a right angle. If you approach side-on, your tyre might not get over the lip and your bike will stop suddenly. 
  • Look out for potholes and tree roots and always be on the alert for changes in the path or road surface. Concentrate on the path ahead. 
  • Watch out for bushes, tree branches or vines that encroach on cycle paths. 
  • Occasionally there are off-leash dogs on paths. Slow down and be prepared to stop as they are often unpredictable and can cause you to fall over.
  •  Ring your bell to let walkers with dogs on leashes know you’re going to pass so they can pull their dog to the side. 
  • Small children enjoy riding as much as we do but many of them zig zag across the path, so be patient, slow down and give them a wide berth.
  • Sometimes soft sand blows onto cycle paths. Avoid sudden braking in soft sand. If unsure, get off and push your bike through. 
  • Loose or stony gravel can also be a hazard, depending on its depth, looseness and on the type of your tyres. Try to ride through evenly and not brake suddenly. 
  • Avoid riding parallel to train and light rail tracks in case your tyre gets caught in them. Don’t brake on wet steel tracks or metal drains as this causes your tyres to slide. 
  • Wooden boardwalks also become slippery when wet. 
  • Don’t attempt tight turns when riding in a group, unless you are confident of following through. 
  • Before riding through any intersection, always check that it is safe to do so – don’t just follow the rider in front. 
  • Don’t ride too close to the rider in front of you in case your wheel clips theirs. 
  • Don’t stop suddenly if you can help it. Shout “stopping” or “slowing” when you’re going to stop. 
  • Look out for approaching hills so you can change your gears before you start the climb.

Riding Two Abreast

30 May 2018

Cyclists often ride two abreast for a reason.  It’s safer. It increases visibility and reduces the chances of being in an accident with a motor vehicle.

Bicycle riders are one of the most vulnerable road users, and riding two abreast make them more visible.  Two riders cycling side by side can be seen from much further away, than a single rider. Being able to see riders from a further distance will enable drivers to prepare to overtake the riders safely, in accordance with the Minimum Passing Distance law.

Riding two abreast also allows the motorist to overtake the group of riders more quickly as the line is only about half as long. This allows the vehicle to pass the group less time (giving for moving in and out to the correct location on the road).  A good overtake is safer for everyone, the other vehicles on the road, the driver and their passengers and all the riders on the road in the group.

Broken Centre Line Overtaking is legal, when safe to do so.

Unbroken Centre Line Overtaking is legal, when safe to do so.

What do cyclists need to know about riding two abreast?

Cyclists must be within 1.5 metres of each other when riding two abreast.  A third rider can overtake these two riders, but cannot continue to ride beside them.

Riders should be courteous and consider other roads users around them, and if safe may change to single file in some circumstances.

What do drivers need to know when overtaking cyclists riding two abreast? 

Only overtake when it is safe and legal to do so. We want all road users to get to their destinations safely.

Drivers in NSW must provide a minimum of 1 metre when overtaking 1 bike rider or multiple.  When the speed limit is 60km/h or under, drivers must provide 1 metre when overtaking – this is measured from the furthest point of vehicle (i.e. mirror) to the furthest point of the cyclists (i.e. handle bars, cyclists elbow). If the speed limit is over 60km/h, drivers must provide 1.5 metres of space when overtaking.

Drivers are able to cross double lines and go on painted islands to provide bike riders with this distance, if it is safe to do so.


A few seconds can save a life so please be patient. Our roads are shared spaces. Mutual respect and cooperation are the key to ensure everyone remains safe. 

Minimum Passing Distance – Update

In May 2018, after a 2 year trial, the Minimum Passing Distance became permanent law in NSW.  Providing space when overtaking cyclists, is helping to protect our most vulnerable road users.


What is the Minimum Passing Distance? 

When driving 60km/h and under, a motor vehicle must provide bike riders 1 metre of space when overtaking.

When driving over 60km/h, a motor vehicle must provide 1.5 metres of space when overtaking.


The measurement is taken from the widest part of the bike (i.e. handle bars) to the widest part of the motor vehicle (i.e. a mirror)

Exemptions to the law that enable driver to provide bike riders with this space. 


Drivers will be exempt from the following rules, as long as it is safe to pass the bicycle rider with at least a metre of space and they have a clear view of approaching traffic:

  • Keep to the left of the centre of the road (two-way road with no dividing line)
  • Keep to the left of the centre of a dividing line – broken and unbroken lines
  • Keep off a flat dividing strip
  • Keep off a flat painted island
  • Driving within a single marked lane or line of traffic
  • Moving from one marked lane to another across a continuous line separating the lanes

Extending the courtesy to paths

When riding on shared path and footpaths, we strongly encourage riders to give pedestrians and other riders 1 metre of space when overtaking.

Bike riders are allowed to ride on footpaths if they are under the age of 12, or are with an under 12 bike rider. This means that parents, guardians, friends and siblings aged 12 years or over are legally allowed to ride on the footpath if they are accompanying a rider under 12.

Driver Education

NSW Parliamentary Inquiry – Driver Education, Training and Road Safety

Watch for cyclists sign In February, Bicycle NSW along with 75 other bodies, made a submission to the NSW Parliamentary Inquiry in to Driver Education, Training and Road Safety. You can read our submission on the NSW Parliament Inquiry website. Our main recommendations were:
  • To include approved bicycle safety courses in the total training hours for Learners that count towards their logbook.
  • Driver Education be included as a compulsory part of the Year 10 PDHPE curriculum in NSW High Schools
  • Include a Vulnerable Road Users component in the Learner rules testing and practical examination
  • For NSW Drivers to undergo a computer based Rules test every 5 years which must include a Vulnerable Road Users component
  • A high priority be given to ongoing driver education through effective media campaigns
  • Transport infrastructure projects to include a component for the Positive Provision of Active Transport Infrastructure
  • The bicycle infrastructure component of the total transport infrastructure budget be raised to 5%
On May 22nd, we appeared alongside the Amy Gillett Foundation and the Australian Cycle Alliance, to present further to the inquiry on our recommendations and need for greater education across all road users. The topic has garnered significant media interest resulting in news articles and radio interviews. We spoke to 2HD Newcastle ahead of the hearing and discussed the proposal and the work our local affiliated BUG, Newcastle Cycleways Movement have been doing in pushing for the CycleSafe Network. We will continue to update our members and stakeholders as the outcomes from the Inquiry are made available.

Increased Fines for Bicycle Offences

Bicycle Fines – More Education, less Big Stick.

Bicycle NSW presents their position on the new fines for bicycle offences;

Dear Members and Friends,

Recently we discussed the mandatory Photo ID issue, and this elicited a great range of responses. Thank you for this.

This week we wanted to present the Bicycle NSW position on the large increases in fines for bicycle offences:

  • Not wearing a helmet: from $71 to $319. Equivalent to the motor cycle fine, even though a motor cycle has much higher power and can reach much higher speeds.
  • Running a red light: from $71 to $425. Equivalent to cars, even though at many intersections bicycles are unable to trigger the traffic signal. This is a 500% increase.
  • Riding dangerously: from $71 to $425. This is a 500% increase.
  • Not stopping at children’s/pedestrian crossing: from $71 to $425. Equivalent to cars.
  • All other general bicycle fines: from $71 to $106.

Our position remains that we oppose the automatic equivalence of bicycle and motor vehicle fines. The fines should be based on the potential negative consequence of the offence. For example at present, some speeding fines for heavy vehicles are much greater than for cars because the potential consequences are considered.

At Bicycle NSW we believe any policy or regulatory changes should make riders safer and encourage riding, so as to benefit health, transport, community and the environment. We do not believe that these fine increases will help achieve these aims. As NSW roads face more and more congestion, the Government should be looking at ways to encourage bike riding as a form of transport, rather than discouraging riding.

We encourage all road users to follow the rules and share the road. We know that a good education campaign is the key to behavioural change. During the Government’s committee process there was no hard evidence that higher fines would produce greater compliance than an effective education campaign. The recent Queensland “Stay Wider of the Rider”,  and the NSW motor cycle safety “Ride to Live” campaigns are good examples.

The proposed new fine levels seem ad hoc, draconian, and particularly to target bicycle riders. In fact, the new bicycle fines lead to some interesting anomalies, eg:

  • Ride bicycle without working warning device (eg bell, horn): $106
  • Pedestrian crossing a level crossing when an approaching tram/train can be seen/heard: $71

Which of these is far more dangerous? And look at:

  • Car driving in a bicycle lane: $177
  • Car driving in a bus lane: $319

Who is the vulnerable road user here?

At Bicycle NSW we will continue to work with the Government to achieve a better solution. To aid this, and support our voice, we suggest that concerned riders should write to their Local MP, and to the Premier seeking a reconsideration of these measures.
